Open Broadcaster Software (OBS) Studio is a great, free program that lets you stream and/or record your entire desktop, a specific application window, a webcam, or a combination of multiple sources. On this page we will discuss the basic settings for a single screen recording.
Contact the TSG for help with more elaborate setups.



==Installation==
Download and run the installer for your operating system from the [https://obsproject.com/download OBS website].

==Configuration==

When opening OBS Studio for the first time, you will see a large black canvas which is the preview window of what you are recording. By default, no source is selected so nothing is visible. Before setting up our source(s), let's make sure our canvas and recording settings are correct, otherwise we'd have to adjust the sources again later. Click the "Settings" button in the bottom right.

===Video Settings===
Go to the "Video" tab and adjust the resolution and frame rate to match your source and desired output. For recording, we advise to keep the Base Resolution and Output Resolution the same; we can always scale down the recorded video later.
[[File:Obs tut videoSet.png|thumb|none|500px|Typical resolution settings for recording on a Full HD monitor.]]

===Output Settings===
Next, go to the "Output" tab and then the "Recording" sub-tab.
*Select your default folder for saving the recordings to under "Recording Path".
*Set your recording format. We recommend using Hybrid MP4<ref>Hybrid MP4 is only available in OBS version 30.2 or newer [https://obsproject.com/kb/hybrid-mp4]</ref>. See [[#Recording Formats]] for more info.

*Select your encoder. You'll probably want to use x264 or Nvidia NVENC H.264 if available.
*Set the Rate Control. CBR is best in most cases, because it ensures the video can be recorded and played back at a consistent bitrate, making it less likely to cause performance drops. The downside is a potentially larger file size.
*Set your Bitrate. Check the [[Video_Codecs#Bitrate|Video Codecs]] page for more info on choosing your bitrate. In our example of a basic 1920x1080 screen recording, 8000Kbps usually gives a good balance between video quality and file size. If you have a lot of fast moving objects or fast changing colors to record, you might want to choose a higher bitrate. If your screen is largely static, or if you use a lower output resolution, you can opt for a lower bitrate to save space on your hard drive.
[[File:Obs tut outputSet.png|thumb|none|500px|A good place to start for recording a Full HD screen]]

If audio is important to you, you can fiddle around with the settings in the "Audio" tabs, but for most cases the default settings will do.
Apply the new settings and close the settings window.

===Sources===
Now let's add a source for our recording. Click the plus icon underneath the "Sources" box at the bottom of the screen. A dropdown menu will appear in which you can select your source(s). OBS allows you to select multiple sources and place them on top of each other (picture in picture), side by side, or in any other configuration. In this guide, we will stick with a single source.
[[File:Obs tut sourceSet.png|thumb|none|500px]]

====Desktop Capture====
To capture your entire screen, select "Display Capture". If you have multiple displays connected, choose the display you wish to record. You can also choose whether to include the mouse cursor in your recording. Click OK when done. If your display resolution matches the canvas resolution we set earlier, you should see our Display Capture source fill the entire preview window. If not, you can drag the red corners of the window to scale it up or down to fill the screen or to position it wherever you want.
[[File:Obs tut desktopCapture.png|thumb|none|500px]]

====Webcam====
To capture a webcam, select "Video Capture Device" form the Sources dropdown menu. From the "Device" dropdown menu, select your webcam. If you do not see your webcam listed, make sure it is connected and not used by another program.
Some webcams will default to a low resolution; you will notice this when the webcam image does not fill up the entire frame. To ensure your webcam is using the correct resolution, scroll down the device properties and set "Resolution/FPS Type" to "Custom". Then type the resolution (e.g. 1920x1080 for our Logitech C920/C922 webcams), and set the FPS (refresh rate) to "Highest FPS" for the most stable stream.

===Saving Your Setup===
When you are happy with your source settings, we strongly recommend saving your settings by going to Scene Collection -> Export. This allows you to recover your settings after an image update, or easily transfer your setup to a different lab.

==Usage==
To start recording, click the "Start Recording" button in the bottom right. The button will change to "Stop Recording", which you can click again to stop recording. The recordings are stored in the folder you specified in the Output settings.

===More Use Cases===
*[[OBS Studio/Recording Multiple Audio Sources|Recording Multiple Audio Sources]]
*[[OBS Studio/Recording A Teams Meeting|Recording a Teams Meeting]]

==Recording Formats==
We typically recommend using MP4 as [[Video Codecs#Container Formats|container format]] for your videos. As of version 30.2, OBS offers 3 flavours of MP4 as its recording format:
*'''MPEG-4''' Regular MP4 container with widespread playback support. Only downside is that your recording will be unrecoverable if OBS crashes before finalizing the file.
*'''Fragmented MP4''' Records video data in fragmented chunks, making it recoverable after a crash, like the MKV container. However, playback support may be limited.
*'''Hybrid MP4''' Records video data as Fragmented MP4, but converts ("remuxes") it to a regular MP4 after the recording ends. It's the best of both worlds, so this is the one we recommend.

We have previously recommended using MKV as recording format and remux to MP4 afterwards. This is still a very useful method. The remuxing can be automated; see below.

=== Remuxing ===
If you have chosen MKV as your recording format but wish to (also) have the video in MP4 format, go to the "Advanced" tab to set OBS to automatically convert ("remux") your recording to MP4 format. This will happen as soon as you press the "Stop Recording" button. Remuxing means it only changes the container, not the codec, and so this will not degrade the video quality.

Video Codecs

2026-04-09T09:59:44Z

E.vandenberge:

We advise users to contact the Technical Support Group to discuss which codec and export settings are best suited for your video stimuli. This page functions only as reference.

For a guide on recording your screen, see [[Screen Recording with OBS]].

== Information ==
=== Codecs ===
To find out what video codecs are and why they are used, grab a cup of coffee (or other non-alcoholic beverage of choice) and reserve about 45 minutes of your life to watch this comprehensive video: [https://vimeo.com/104554788 How Codecs Work (Vimeo)].

=== Bitrate ===

When compressing a video, you will be asked to enter a 'bitrate'. This is what determines how much information is stored for every second of video. The more information, the higher the quality of the video. The tradeoff is file size. The more information, the larger the file. So setting a bitrate is striking a balance between limiting the file size without losing too much quality. The smarter the compression format, the easier this is to achieve.

If you are using H.264 compression, you can calculate a ballpark estimate for your target bitrate using the Kush gauge, a helpful formula written by a guy named Kush:
Target Bitrate (kbps) = Frame Width (px) * Frame Height (px) * Frame Rate (fps) * Motion Factor * 0.07 / 1000
"Motion Factor" is an arbitrary value (typically 1, 2 or 4) that you can assign to your video based on the amount of (fast) movement in the video. Higher amounts of movement require a higher amount of information to be stored in order to prevent quality loss.
Example calculation for a typical 720p video:
1280 * 720 * 25 * 2 * 0.07 / 1000 = 3225.6 kbps (= 3.2 Mbps)

Bitrate can be set to Constant (CBR) or Variable (VBR). A variable bitrate can help decreasing file size when your video has a combination of high and low amounts of movement, as it will optimize the distribution of information storage for those parts in your video. The downside is that your video player has to sometimes suddenly decode a lot more information than the previous frame, potentially causing laggy playback. For this reason, we advise using a constant bitrate.

=== HEVC ===
High Efficiency Video Coding (HEVC, also known as H.265) is the successor to H.264. Together with AVC, VP9 and AV1, it is one of the latest standards that yield significantly better compression rates than H.264. However, support is still far from universal and you may experience performance issues in some programs or on some devices. Therefore, we do not advise storing your videos in these formats unless it is for archival purposes only.

=== Container Formats ===
The container format determines what extension your video file will have, and provides information about how the video data is structured. Video container formats are often independent from codecs! So you can't always tell which codec is used by looking at the file extension. This sometimes leads to playback errors, when your software is able to open a container, but not able to decode the video data inside. Or visa-versa, like [[#Presentation|Presentation]]. So it's important to choose both the right codec AND right container for your videos!
Some container formats offer more features than others. A comparison of the most common video formats is found here: [https://en.wikipedia.org/wiki/Comparison_of_video_container_formats]

When using the H.264 or HEVC codec, the most common container format is MP4.

Note: This list is incomplete and will be updated as soon as we have tested all the common and recommended video formats with all supported stimuli software.

== Neurobs Presentation ==

Neurobs Presentation does not support the .mp4 container, so you will have to convert your H.264 encoded .mp4 videos to the .avi container. We recommend doing this with [[FFmpeg]].

Neurobs recommends using MP4Cam2AVI Easy Converter<ref>http://www.neurobs.com/wiki/Presentation/Video#Video_Encoding</ref>. Be sure to uncheck 'preview On' before opening your files, because the program might crash otherwise.

{{Warn|There are performance issues with playing videos in Presentation. Please contact the TSG if you plan to use videos in your Presentation experiment.}}

== Downloads ==
=== Converters ===
We recommend using [[FFmpeg]] for encoding/converting your videos. If you prefer using a GUI for converting to mp4, Handbrake is a decent option. Find a quick start guide here: https://handbrake.fr/docs/en/latest/introduction/quick-start.html

}}

The Hollyland Lark M2 is a wireless lavalier microphone system. It does not offer much in terms of controls and features, but this makes it very easy to use.
It is ideal in situations where you need a small, unobtrusive microphone to record someone for e.g. a promotional video, or when you are interviewing people on location.

If you're worried about sound quality, latency, and fine adjustments, this is not the microphone for you.



==Contents==
The Hollyland Lark M2 Camera kit contains:
* 2 Wireless lavalier microphones (transmitters)
* 1 Wireless receiver
* 1 Charging case
* 2 wind screens
* Carry bag
* Magnetic clips and lanyards for attaching the transmitters to
* USB-C, Apple Lightning and 3.5mm jack cables
* Stickers to cover the Hollyland logo <ref>Stickers can be requested from TSG</ref>

We also have some Lark M2 Combo kits available that add low-profile receivers for smartphone or [[Ipod]].

==Usage==
The Lark M2 has no internal storage, so you will always have to connect it to a separate recording device, like a regular microphone.

# Take a transmitter and the receiver out of the charging case. They will automatically turn on and connect to each other.
# Attach the transmitter to your subject (see attachment options below)
# Connect the receiver to your camera/phone/computer via USB or 3.5mm jack.
# Turn the volume knob on the receiver to adjust input volume.

When you are done recording, place everything back in the charging case. The transmitter(s) and receiver will be automatically recharged from the case's internal battery. Make sure to recharge the case itself when the indicator lights on the front run low.

===Attachment options===
The Lark M2 transmitters can be magnetically attached to your subject using the included magnets, clips or lanyards.
* Use the clip to clip the transmitter to e.g. a collar or the edge of a button-up shirt.
* Hold a magnet on the inside of a shirt and snap the transmitter in place on the outside (like a sandwich).
* Use the lanyard in case someone is wearing very delicate fabric or no shirt at all.
* Use the magnet to attach the transmitter to a nearby metal object (or actual microphone stand).

The magnet sandwich is often the most secure way of fixing the microphone in place, but make sure to ask consent before sticking your hand up someone's shirt.

For the best results, make sure the transmitter is not covered by any layers of clothing or hair that may rustle against it.

Attach a wind screen when recording outside in windy conditions.

=== Noise cancelling ===
Press the button on the transmitter to enable noise cancelling (LED will turn green). This can work great at filtering unwanted environment noise, but will likely decrease your overall audio quality. Press the button again to turn noise cancelling off (LED will turn blue).

=== Stereo recording ===
By default, the Lark M2 will record mono, meaning the signal of both transmitters will be combined into one audio stream. Stereo recording, whereby transmitter 1 is recording to the left channel and transmitter 2 is recording to the right channel, is only possible via 3.5mm jack output.
Adapter cables and audio interfaces are available at TSG to allow you to record separated channels via USB.

To enable stereo mode, press the Mode Switching button on the receiver (volume indicator LEDs will turn blue). Press again to switch back to mono mode (volume indicator LEDS will turn green).

Note: when connecting the Lark M2, it will present itself as a stereo input device, even if it is in mono mode. In mono mode, the combined signal is sent to both channels equally.

The Hollyland Lark M2 is a wireless lavalier microphone system. It does not offer much in terms of controls and features, but this makes it very easy to use.
It is ideal in situations where you need a small, unobtrusive microphone to record someone for e.g. a promotional video, or when you are interviewing people on location.

If you're worried about sound quality, latency, and fine adjustments, this is not the microphone for you.



==Contents==
The Hollyland Lark M2 Camera kit contains:
* 2 Wireless lavalier microphones (transmitters)
* 1 Wireless receiver
* 1 Charging case
* 2 wind screens
* Carry bag
* Magnetic clips and lanyards for attaching the transmitters to
* USB-C, Apple Lightning and 3.5mm jack cables
* Stickers to cover the Hollyland logo <ref>Stickers can be requested from TSG</ref>

==Usage==
The Lark M2 has no internal storage, so you will always have to connect it to a separate recording device, like a regular microphone.

# Take a transmitter and the receiver out of the charging case. They will automatically turn on and connect to each other.
# Attach the transmitter to your subject (see attachment options below)
# Connect the receiver to your camera/phone/computer via USB or 3.5mm jack.
# Turn the volume knob on the receiver to adjust input volume.

When you are done recording, place everything back in the charging case. The transmitter(s) and receiver will be automatically recharged from the case's internal battery. Make sure to recharge the case itself when the indicator lights on the front run low.

===Attachment options===
The Lark M2 transmitters can be magnetically attached to your subject using the included magnets, clips or lanyards.
* Use the clip to clip the transmitter to e.g. a collar or the edge of a button-up shirt.
* Hold a magnet on the inside of a shirt and snap the transmitter in place on the outside (like a sandwich).
* Use the lanyard in case someone is wearing very delicate fabric or no shirt at all.
* Use the magnet to attach the transmitter to a nearby metal object (or actual microphone stand).

The magnet sandwich is often the most secure way of fixing the microphone in place, but make sure to ask consent before sticking your hand up someone's shirt.

For the best results, make sure the transmitter is not covered by any layers of clothing or hair that may rustle against it.

Attach a wind screen when recording outside in windy conditions.

=== Noise cancelling ===
Press the button on the transmitter to enable noise cancelling (LED will turn green). This can work great at filtering unwanted environment noise, but will likely decrease your overall audio quality. Press the button again to turn noise cancelling off (LED will turn blue).

=== Stereo recording ===
By default, the Lark M2 will record mono, meaning the signal of both transmitters will be combined into one audio stream. Stereo recording, whereby transmitter 1 is recording to the left channel and transmitter 2 is recording to the right channel, is only possible via 3.5mm jack output.
Adapter cables and audio interfaces are available at TSG to allow you to record stereo channels via USB.

To enable stereo mode, press the Mode Switching button on the receiver (volume indicator LEDs will turn blue). Press again to switch back to mono mode (volume indicator LEDS will turn green).

Open Broadcaster Software (OBS) Studio is a great, free program that lets you stream and/or record your entire desktop, a specific application window, a webcam, or a combination of multiple sources. On this page we will discuss the basic settings for a single screen recording.
Contact the TSG for help with more elaborate setups.



==Installation==
Download and run the installer for your operating system from the [https://obsproject.com/download OBS website].

==Configuration==

When opening OBS Studio for the first time, you will see a large black canvas which is the preview window of what you are recording. By default, no source is selected so nothing is visible. Before setting up our source(s), let's make sure our canvas and recording settings are correct, otherwise we'd have to adjust the sources again later. Click the "Settings" button in the bottom right.

===Video Settings===
Go to the "Video" tab and adjust the resolution and frame rate to match your source and desired output. For recording, we advise to keep the Base Resolution and Output Resolution the same; we can always scale down the recorded video later.
[[File:Obs tut videoSet.png|thumb|none|500px|Typical resolution settings for recording on a Full HD monitor.]]

===Output Settings===
Next, go to the "Output" tab and then the "Recording" sub-tab.
*Select your default folder for saving the recordings to under "Recording Path".
*Set your recording format. We recommend using MKV, because this format allows you to recover the video in case of a crash. See below how to automatically convert the file to MP4 after your recording, which is typically the format you want to use if you want to edit the video later.
*Select your encoder. You'll probably want to use x264 or Nvidia NVENC H.264 if available.
*Set the Rate Control. CBR is best in most cases, because it ensures the video can be recorded and played back at a consistent bitrate, making it less likely to cause performance drops. The downside is a potentially larger file size.
*Set your Bitrate. Check the [[Video_Codecs#Bitrate|Video Codecs]] page for more info on choosing your bitrate. In our example of a basic 1920x1080 screen recording, 8000Kbps usually gives a good balance between video quality and file size. If you have a lot of fast moving objects or fast changing colors to record, you might want to choose a higher bitrate. If your screen is largely static, or if you use a lower output resolution, you can opt for a lower bitrate to save space on your hard drive.
[[File:Obs tut outputSet.png|thumb|none|500px|A good place to start for recording a Full HD screen]]

If audio is important to you, you can fiddle around with the settings in the "Audio" tabs, but for most cases the default settings will do.
Apply the new settings and close the settings window.

===Advanced Settings===
If you have chosen MKV as your recording format, go to the "Advanced" tab to set OBS to automatically convert ("remux") your recording to MP4 format. This will happen as soon as you press the "Stop Recording" button. Remuxing means it only changes the container, not the codec, and so this will not degrade the video quality.

ℹ️As of version 30.2, OBS has introduced the new "Hybrid MP4" and "Hybrid MOV" containers<ref>[https://obsproject.com/kb/hybrid-mp4 Hybrid MP4 & Hybrid MOV Formats]</ref>, which aim to combine the convenience of MP4/MOV and the recoverability of MKV. We have not extensively tested it yet, and recommend sticking with the MKV + remux option for now.
[[File:Obs tut advancedSet.png|thumb|none|500px|Set OBS to automatically remux the recording file to MP4]]

===Sources===
Now let's add a source for our recording. Click the plus icon underneath the "Sources" box at the bottom of the screen. A dropdown menu will appear in which you can select your source(s). OBS allows you to select multiple sources and place them on top of each other (picture in picture), side by side, or in any other configuration. In this guide, we will stick with a single source.
[[File:Obs tut sourceSet.png|thumb|none|500px]]

====Desktop Capture====
To capture your entire screen, select "Display Capture". If you have multiple displays connected, choose the display you wish to record. You can also choose whether to include the mouse cursor in your recording. Click OK when done. If your display resolution matches the canvas resolution we set earlier, you should see our Display Capture source fill the entire preview window. If not, you can drag the red corners of the window to scale it up or down to fill the screen or to position it wherever you want.
[[File:Obs tut desktopCapture.png|thumb|none|500px]]

====Webcam====
To capture a webcam, select "Video Capture Device" form the Sources dropdown menu. From the "Device" dropdown menu, select your webcam. If you do not see your webcam listed, make sure it is connected and not used by another program.
Some webcams will default to a low resolution; you will notice this when the webcam image does not fill up the entire frame. To ensure your webcam is using the correct resolution, scroll down the device properties and set "Resolution/FPS Type" to "Custom". Then type the resolution (e.g. 1920x1080 for our Logitech C920/C922 webcams), and set the FPS (refresh rate) to "Highest FPS" for the most stable stream.

===Saving Your Setup===
When you are happy with your source settings, we strongly recommend saving your settings by going to Scene Collection -> Export. This allows you to recover your settings after an image update, or easily transfer your setup to a different lab.

==Usage==
To start recording, click the "Start Recording" button in the bottom right. The button will change to "Stop Recording", which you can click again to stop recording. The recordings are stored in the folder you specified in the Output settings.

Our [[Lab Computer]]s are installed with a [[wikipedia:System_Image|System Image]] to unify software and driver versions and configuration in all BSI and DCC labs. This allows researchers to easily transfer their experiments from one lab to the other in case of booking constraints, or conduct research in multiple labs simultaneously with identical settings.
The TSG will periodically update this image to improve performance and security. 
During the update, the Windows (C:\) and Linux system drives will be wiped, as may the Data (D:\) drive. Therefore, please make sure to transfer your data from the Data drive to your network drive every time you leave the lab.

==Configuration==
The system image for the lab computers installs a configuration with Windows 11. The storage drive is partitioned into system drives and data drives. As mentioned above, the system drives will be wiped during a system image update. The data drive(s) can be used to install your experiment scripts on and write data from your experiment to, but are not meant as long-term storage.

==Pre-Installed Software==
Below is a list of the most frequently used applications that are installed as part of the system image. 
⚠️This list is incomplete and outdated. Please contact our [[Administrator]] if you want to know if a certain program or additional version is installed, or check the [[System_Image/Changelog | changelog]].

FFmpeg is an open-source command-line tool to convert audio and video files. 
We know command-line tools can seem scary! But conversion software GUIs are often a more limiting, or will obfuscate what gets done to your video or audio file. For the highest level of control and transparency, we therefore highly recommend using FFmpeg for all your AV conversion needs.



==Installation==
===Windows 10/11===
#Download the latest ffmpeg-release-full build on https://ffmpeg.org/download.html
#Unpack the 7z/zip file anywhere you like
#Add ffmpeg to Windows' Environment Variables:
## Open the start menu and start typing "Environment Variables"
## Select "Edit the system environment variables"
## Click "Environment Variables"
## Select "Path" and click "Edit"
## Click "Browse" and go to the folder where you unpacked your FFmpeg files. Select the 'bin' folder inside (e.g. "C:\ffmpeg\bin")
## Click OK on all previously opened windows.
# To test, go to the command line (Windows+R -> cmd) and type {{cmdline|ffmpeg}}. It should tell you the installed ffmpeg version.

==Usage==
FFmpeg needs to be run from the command line, but you can create batch scripts to automate the process for multiple files. There is also a plugin for Python (https://pypi.org/project/ffmpeg-python/), but it is fairly limited so we recommend using subprocess instead (see example below).

The following are examples of conversions that we commonly use. For [[Psychopy]] applications, please follow the more strict instructions under [[Video Playback#FFmpeg]].

===Basic Format Conversion===
{{cmdline|ffmpeg -i input.mp4 output.avi}}

<code>-i</code> specifies input file

The last argument is always the output file. Without specifying any codec or bit rate (see examples below), FFmpeg will encode the video (and audio, if included) using some arbitrary default settings, depending on the input file and output format.

===Encoding===
{{cmdline|ffmpeg -i input.mp4 -vcodec h264 -b:v 8M -r:v 25 -acodec aac -b:a 256k output.mp4}}

<code>-vcodec h264</code> specifies video codec. "h264" is a shorthand for FFmpeg's x264 encoder, it is (by default) interchangeable with "x264" or "libx264". "-vcodec" is interchangeable with "-c:v".

<code>-b:v 8M</code> sets the video bit rate, in bits per second. You can use "k" or "M" as shorthand for a thousand or a million respectively. See [[Video Codecs]] for help choosing a bit rate.

<code>-r:v 25</code> sets the video frame rate, in frames per second. By default, the frame rate of the original video is kept.

<code>-acodec aac</code> specifies audio codec. AAC is used by default if your output is a .mp4 file. For AVI the default is MP3. "-acodec" is interchangeable with "-c:a".

<code>-b:a</code> sets the audio bit rate, in bits per second. Default for AAC is 128k.

===Remove audio from video file===
{{cmdline|ffmpeg -i input.mp4 -vcodec copy -an output.mp4}}

<code>-vcodec copy</code> means the video won't be re-encoded, preserving the quality.

<code>-an</code> strips the audio

===Extract single audio channel from video file===
<code style="background-color:#000; color:#fff; padding:1px 3px;">ffmpeg -i input.mp4 -af "pan=mono|c0=c0" output.wav</code>

<code>-af "pan=mono|c0=c0"</code> extracts a single channel from the file. Use <code>c0=c0</code> for left channel, <code>c0=c1</code> for right channel (assuming source audio is stereo).

===Add audio to video===
{{cmdline|ffmpeg -i inputvideo.mp4 -i inputaudio.wav -vcodec copy -map 0:v -map 1:a output.mp4}}

<code>-i</code> is used twice here to add a second input file.

<code>-map 0:v</code> tells FFmpeg to take video from the first input (count starts at 0)

<code>-map 1:a</code> tells FFmpeg to take audio from the second input (1)

===Trimming video===
{{cmdline|ffmpeg -i input.mp4 -ss 00:00:04 -to 00:00:06 -vcodec h264 -b:v 8M output.mp4}}

<code>-ss 00:00:04</code> specifies the starting time, in this case 4 seconds (use format HH:MM:SS, or HH:MM:SS.MS)

<code>-to 00:00:06</code> specifies end point, in this case 6 seconds (same formatting as above)

Alternatively, instead of <code>-to</code>, you can use <code>-t 00:00:02</code> to cut exactly 2 seconds from the starting time.

<code>-vcodec h264</code> specifies video codec.

<code>-b:v 8M</code> specifies video bit rate, in this case 8Mbit/s, which determines video quality.

Note: you can use <code>-c copy</code> to trim without re-encoding, but in this case FFmpeg can only cut to the nearest keyframe, so the output may not be exactly the same length as specified.

===Batching===
The following is a batch script (text file with .bat file extension) that converts all .mp4 files in the specified folder to .avi:
<syntaxhighlight lang="batch" overflow:auto;">@echo off
setlocal enabledelayedexpansion

:: Set source video folder, as absolute path or relative to this script
set src="videos"

:: Set destination folder
set dst="videos/converted"

for /R %src% %%F in (*.mp4) do (
:: Put your FFmpeg command here
ffmpeg -i "%%F" -vcodec copy "%dst%\%%~nF.avi"
)

pause
</syntaxhighlight >

===Python===
<syntaxhighlight lang="python" overflow:auto;">import subprocess

inputFile = "input.mov"
outputFile = "output.mp4"

subprocess.run(f'ffmpeg -i "{inputFile}" -vcodec h264 -b:v 8M "{outputFile}"')
</syntaxhighlight >
The command within <code>subprocess.run()</code> is the same as you would type into the command line. You can use Python's [https://docs.python.org/3/tutorial/inputoutput.html#tut-f-strings string formatting] to insert variables.

The RME Babyface Pro FS is a professional USB audio interface. The device is fully configurable in software, giving you complete control over all audio inputs and outputs.



==Specifications==

==Installation==
The RME drivers and TotalMix FX software are installed on all our lab computers as part of the [[System Image]].

==Configuration==
We recommend using the TotalMix FX software to configure your device, instead of using the controls on the device itself. This way, you can save and load your settings, giving you consistent results for all your experiments.

Ask the TSG for help configuring your device.

⚠️ '''NEVER''' turn on 48V (Phantom Power) on any input channel unless you are sure you're using a compatible [[microphone]].



==Usage==
# Open Totalmix FX from the start menu or the system tray.
# Load your Workspace (File -> Load Workspace)
# Load your Snapshots (File -> Load Snapshot)
# Select your snapshot; Check channel configuration
# When using (a) microphone(s) to record participants; adjust the gain on the input channel to compliment their speaking volume.

⚠️Input gain is set by the Gain knob; '''NOT''' by the input fader (slider). The fader only controls how much of the input gets routed to the output (e.g. speakers or headphones).

Open Broadcaster Software (OBS) Studio is a great, free program that lets you stream and/or record your entire desktop, a specific application window, a webcam, or a combination of multiple sources. On this page we will discuss the basic settings for a single screen recording.
Contact the TSG for help with more elaborate setups.



==Installation==
Download and run the installer for your operating system from the [https://obsproject.com/download OBS website].

==Configuration==

When opening OBS Studio for the first time, you will see a large black canvas which is the preview window of what you are recording. By default, no source is selected so nothing is visible. Before setting up our source(s), let's make sure our canvas and recording settings are correct, otherwise we'd have to adjust the sources again later. Click the "Settings" button in the bottom right.

===Video Settings===
Go to the "Video" tab and adjust the resolution and frame rate to match your source and desired output. For recording, we advise to keep the Base Resolution and Output Resolution the same; we can always scale down the recorded video later.
[[File:Obs tut videoSet.png|thumb|none|500px|Typical resolution settings for recording on a Full HD monitor.]]

===Output Settings===
Next, go to the "Output" tab and then the "Recording" sub-tab.
*Select your default folder for saving the recordings to under "Recording Path".
*Set your recording format. We recommend using MKV, because this format allows you to recover the video in case of a crash. See below how to automatically convert the file to MP4 after your recording, which is typically the format you want to use if you want to edit the video later.
*Select your encoder. You'll probably want to use x264 or Nvidia NVENC H.264 if available.
*Set the Rate Control. CBR is best in most cases, because it ensures the video can be recorded and played back at a consistent bitrate, making it less likely to cause performance drops. The downside is a potentially larger file size.
*Set your Bitrate. Check the [[Video_Codecs#Bitrate|Video Codecs]] page for more info on choosing your bitrate. In our example of a basic 1920x1080 screen recording, 8000Kbps usually gives a good balance between video quality and file size. If you have a lot of fast moving objects or fast changing colors to record, you might want to choose a higher bitrate. If your screen is largely static, or if you use a lower output resolution, you can opt for a lower bitrate to save space on your hard drive.
[[File:Obs tut outputSet.png|thumb|none|500px|A good place to start for recording a Full HD screen]]

If audio is important to you, you can fiddle around with the settings in the "Audio" tabs, but for most cases the default settings will do.
Apply the new settings and close the settings window.

===Advanced Settings===
If you have chosen MKV as your recording format, go to the "Advanced" tab to set OBS to automatically convert ("remux") your recording to MP4 format. This will happen as soon as you press the "Stop Recording" button. Remuxing means it only changes the container, not the codec, and so this will not degrade the video quality.
[[File:Obs tut advancedSet.png|thumb|none|500px|Set OBS to automatically remux the recording file to MP4]]

===Sources===
Now let's add a source for our recording. Click the plus icon underneath the "Sources" box at the bottom of the screen. A dropdown menu will appear in which you can select your source(s). OBS allows you to select multiple sources and place them on top of each other (picture in picture), side by side, or in any other configuration. In this guide, we will stick with a single source.
[[File:Obs tut sourceSet.png|thumb|none|500px]]

====Desktop Capture====
To capture your entire screen, select "Display Capture". If you have multiple displays connected, choose the display you wish to record. You can also choose whether to include the mouse cursor in your recording. Click OK when done. If your display resolution matches the canvas resolution we set earlier, you should see our Display Capture source fill the entire preview window. If not, you can drag the red corners of the window to scale it up or down to fill the screen or to position it wherever you want.
[[File:Obs tut desktopCapture.png|thumb|none|500px]]

====Webcam====
To capture a webcam, select "Video Capture Device" form the Sources dropdown menu. From the "Device" dropdown menu, select your webcam. If you do not see your webcam listed, make sure it is connected and not used by another program.
Some webcams will default to a low resolution; you will notice this when the webcam image does not fill up the entire frame. To ensure your webcam is using the correct resolution, scroll down the device properties and set "Resolution/FPS Type" to "Custom". Then type the resolution (e.g. 1920x1080 for our Logitech C920/C922 webcams), and set the FPS (refresh rate) to "Highest FPS" for the most stable stream.

===Saving Your Setup===
When you are happy with your source settings, we strongly recommend saving your settings by going to Scene Collection -> Export. This allows you to recover your settings after an image update, or easily transfer your setup to a different lab.

==Usage==
To start recording, click the "Start Recording" button in the bottom right. The button will change to "Stop Recording", which you can click again to stop recording. The recordings are stored in the folder you specified in the Output settings.

E.vandenberge: /* Scene Setup */

For data security reasons, we generally advise against using the built-in recording options in Microsoft Teams (or similar software) when wishing to record e.g. an online interview with research participants.
Instead, you could record the session locally, with [[OBS Studio]].

⚠️ '''ALWAYS''' check with your institute's data security guidelines/steward/officer if recording is allowed. 
⚠️ '''ALWAYS''' get explicit consent from all people involved in the call before recording. 

==Configuration==

===Scene Setup===

# Set up a new scene with Desktop Capture (see [[OBS Studio#Configuration]]).

(You can also setup Application Capture for Teams specifically, if you don't wish to record the entire desktop)

===Audio Settings===
# Goto File -> Settings
# Goto the Audio page (sidebar).
# Set "Desktop Audio" to "Default".
# Set "Mic/Auxiliary Audio" to your microphone.
# Click "Apply"; Close Settings menu.
# Check audio levels in the Audio Mixer by playing some music on your computer and speaking into the microphone.

Desktop Audio (what you hear) is used to record everyone else in the call. 
Your microphone is used to record your voice, as this is otherwise not included.

====Notes====
* You may need to turn off Exclusive mode in your microphone settings, as it needs to be accessed by both Teams and OBS at the same time:
*# In Windows 10/11: Open Start Menu and type "control panel" -> Open Control Panel.
*# Select View By: Small Icons.
*# Click "Sound".
*# Go to "Recording" tab.
*# Select your microphone and click "Properties".
*# Select Advanced tab.
*# Uncheck "Allow applications to make exclusive control of this device".
*# Click "Apply" and close all settings windows.
* Ideally, set your desktop volume to 100%. Otherwise, the desktop audio will be very quiet in the recording. We recommend using an external headphone volume controller to adjust your headphone volume. Most [[Audio Interface]]s have independent volume control for main output and headphones.
* Optionally, you can configure your track routing to record desktop audio and your microphone on different tracks. See [[OBS Studio/Recording Multiple Audio Sources#Track Routing]] for example.

==Recording==
# Set up your Teams view in a way that makes sense for the recording.
# In OBS Studio, click "Start Recording" to start recording when you're ready.
# Click "Stop Recording" to stop recording.

The recorded video file can be found in the folder you selected before. You can open said folder via File -> Show Recordings.

⚠️ '''ALWAYS''' let people know when the recording has started and ended.

Qualisys is a Swedish manufacturer of high-end optical motion capture systems. Several Qualisys systems are in use within the Faculty of Social Sciences.

Motion capture data can be collected and processed using QTM, for which a site license is available.


==Cameras==
A Qualisys system is an optical motion capture system, meaning it uses cameras to record motion of your subject. This is traditionally done with markers, which emit or reflect infrared light that can be captured by the cameras. By placing multiple cameras in different locations, the system can triangulate the position of a marker.

A typical capture setup (in our labs) consists of 8-10 cameras, placed in a circle around the capture area. Usually, all cameras in a system are the same type, but Qualisys cameras can be mixed and matched to some extent. Cameras with the same connector can be daisy-chained together, and otherwise separate "loops" can be joined via a network switch. When combining different cameras, the maximum frame rate of the entire system is limited to the maximum frame rate of the "worst" camera.

Every Qualisys camera can be used in either "Marker mode" or "Video mode". In Marker mode, they contribute to calculating the 3D position of each marker. In Video mode, the camera captures a regular video (avi), to either aid in labeling markers and movements, or to process for markerless motion capture. Cameras in Video mode do not contribute to marker tracking.

==Markers==
[[File:Passive markers.jpg|thumb|240px|A selection of passive markers]]

Passive markers are little (hemi)spheres covered in retro-reflective material. They reflect the light emitted by the cameras, so that they show up on the camera's sensor. Markers come in all sizes from 2 - 50mm, and with different atachment methods (glue-on, velcro or screw).
Choice of marker size depends on the subject and the distance between the subject and the cameras. The smaller the subject (e.g. baby's fingers), the smaller the marker needs to be. But the smaller the marker, the higher the resolution or the closer the camera should be to capture it.

The benefit of using passive markers is that they are (relatively) cheap, and they need no cables for power or anything. The downside is that passive markers are not inherently identifiable, meaning they need to be manually labeled afterwards and cannot be streamed in real-time unless they are part of a rigid body. A rigid body is an object with 3 or more markers

All optical markers (both active and passive) have the disadvantage of being easily obscured (something blocking the view from the cameras to the marker, making it impossible to track). Therefore, marker placement has to be considered carefully, and often it is wise to place additional markers for redundancy. Standard marker placement templates exist for full/partial body tracking.

===Active Markers===
Active markers are markers that emit infrared light themselves. They require an active power source (meaning they're attached to cables), but they can potentially work over longer distances, and most of all they can be individually identified.

The TSG is currently (August 2025) testing Qualisys' "Traqr" active marker systems; they will likely be available for use in the labs in the near future.

==Usage==
If you wish to capture motion with a Qualisys system, please contact the TSG. They will assist you in determining which system is best suited for your needs and, when available, will set it up for you in one of our research labs.
A training session with [[Erik van den Berge]] is required before you can use the system.

===New Project===
At the start of your experiment, or whenever you have made significant changes to the setup/configuration, you should create a new QTM project. You can do this when launching QTM -> New Project, or File -> New Project if you already have a project open.

Give your project a distinct name (preferably includes your personal and/or research-project name) and select the project folder path. The folder is best located inside your own user folder on the D:/ drive. Create one if you haven't already.

We often recommend basing the new project on an existing project, which is an option in the New Project window. This will copy all settings, 6DOF bodies, AIM models and scripts from a previous project; saving you some time setting things up.

Choose 'Base the project on: "Settings Imported from another project"' and select the Settings.qtmproj file from the base project. There's usually a TSG-created project matching the current camera-setup, that you can use as base.

Don't forget to periodically back-up your project folder! (even if you only use QTM for streaming)

===Rigid Body Tracking===
In QTM, you can define rigid bodies; objects with multiple (>3) markers in a fixed configuration that can be tracked in 6 degrees of freedom (position X,Y,Z + pitch, yaw, roll).
Consult the QTM manual or the TSG for creating a rigid ("6DOF") body.

Rigid bodies can be saved and loaded via Project Options -> Processing -> 6DOF Tracking. This is handy when using common objects between multiple projects.
Be careful when loading a rigid bodies XML file: this will clear any existing bodies from the list! If you wish to add multiple sets of rigid body files, it is best to manually combine the XML files.

===Automatic Identification of Markers (AIM)===
For cases where it isn't possible to create a rigid body, but where marker relations ''are'' constrained in some way (e.g. as part of an arm where the distance between each joint doesn't change but their rotations may), QTM's unique AIM system offers a potential solution to aid in labeling markers. This can save time in post-processing, and allow real-time streaming of individual markers.

Consult the QTM manual or the TSG for creating an AIM model.
Like rigid bodies, AIM models are transferable between projects.

===LSL===
Data from QTM can be streamed in real-time, as well as in playback-mode, via LSL using the [https://github.com/qualisys/qualisys_lsl_app Qualisys LSL App]. Only labeled markers (3D) and rigid bodies (6DOF) can be streamed over LSL.

The TSG has developed a GUI script that lets you launch the LSL app from within QTM. It is usually included when copying a TSG project (see [[#New Project]]).

===Data Processing===
When you have captured marker data, you can process it in QTM to label the markers and fill any gaps. Some analysis tools are available within QTM; otherwise you can export the data in a suitable format (c3d, matlab, tsv, fbx).
You can request access to QTM on your own PC from [[Erik van den Berge]].

===Mouse Sensitivity===
You can change the sensor sensitivity of our Logitech mice to change how fast the pointer moves across the screen with every inch traveled. This is measured in dots per inch (DPI).
Press the DPI button below the scroll wheel to cycle through presets. A notification will pop up on screen telling you the current DPI level. Warning: notification may be delayed if you press the button multiple times!

If you want to set the mouse sensitivity at a custom DPI value, or if you wish to prevent participants from changing the sensitivity (accidentally or otherwise), please contact the TSG.

Note: this is completely independent from the pointer speed setting in Windows Settings. That slider should ALWAYS be set to 6 (the middle position), as any other value may introduce pointer acceleration, which is almost never wanted. "Enhance pointer precision" should be off for the same reason.

Using labs

2026-02-19T09:48:09Z

E.vandenberge:

Here are some general rules for using BSI and DCC labs.

==Keys==
There is valuable equipment in the labs. Therefore lab keys should be handled with caution. Researchers must keep the key with them at all times and do not lend it to others. Even when leaving the lab for a short while, all doors must be locked.

==Noise==
Within the DCC lab area, noise levels must be kept to a minimum. In consideration of your colleagues working in the labs, you are expected to speak softly and limit conversation with others.
All mobile phones and pagers, of both experimenters and participants, should be switched off in the lab.

==Food/drinks==
Food is '''not''' allowed in the lab area, including candy for participants. Drinks are allowed for EEG-participants.

==Equipment==

===Hardware===
Without explicit authorization by the TSG, (re)moving hardware (computers, keyboards, mice, button boxes, electro-caps, furniture, etc.) is strictly prohibited! In case you want to change the technical setup in a lab, you have to discuss this in advance with the [[Lab Coordinator]] and/or a member of the TSG. The last registered user will be held responsible for any damaged or missing equipment.
After conducting an experiment, the lab should be restored in its original state.

===Software===
Do not change any of the software settings installed on the [[Lab Computer]]s. Do not install any programs unless explicitly authorized by the TSG.
Software updates are performed on all lab computers simultaneously.

Your experiment scripts should be stored on ''data drive'' (D:\).
Never run your scripts from a USB drive or network drive, as this can heavily impact performance.

==Data==
Always save experiment scripts and data on the ''data drive'' (D:\)!
The C:\ drive will be '''wiped''' with every round of periodic maintenance. This can include the desktop and user folders.

Back up your data to a workgroup drive at the end of each day you're running the experiment. You can use Ruconnect for this (icon on desktop)

Never save your data to a network drive directly, as this can impact performance.

==Lab supplies==
In case there is a shortage of supplies, or if you need something that you cannot find in the lab, please contact the [[Lab Coordinator]]. Do not take supplies from other labs without consent from the lab coordinator, or (in absence of the lab coordinator) one of the TSG members.

==DCC lab 'Buddy rule'==
For reasons of general safety on both researchers as participants the DCC decided to implement a buddy rule for measurements outside office hours. Please respect this rule from now on.

Details on the rule can be found below or on the following intranet page: https://intranet.donders.ru.nl/index.php?id=4706

"buddy rule" experiments

Testing outside office hours, e.g. between 6pm and 9am, weekends and holidays can only be done when, next to the participant, at least two people are present, the so-called "buddy rule".

The “buddy rule” entails:
• At all times during outside office hours, the experimental subject has to be supervised by the experimenter and one additional person (both with DCC-checked-in status).
• The buddy should be present in the control room of the lab, or if the lab lacks such a room, it is allowed that the buddy stays in an adjacent room, of which the door is left open.
• The buddy-system applies to ALL labs.
• The experimenter is responsible for finding a buddy.
• No buddy is needed if both the experimenter and the subject have a DCC-checked-in status. In this case both should be in the same room or in directly adjacent rooms with recording door left open, such that subject and researcher are not fully separated.
In addition, it is the responsibility of the experimenter to make sure that safety-procedures are known to both experimenter and the subject.
6. Please note that for interventional studies, a buddy always needs to be present, also during office hours! (See also brain stimulation guidelines for TMS-specific rules, https://intranet.donders.ru.nl/index.php?id=4707)

The DCC is aware that this puts an extra claim on the time available to all of you. However, this rule has to be implemented for reasons of general safety on both the participant as well as the experimenter.

Cameras are video capturing devices that can turn your cat into a Tiktok or Instagram sensation. They can also be used to create stimulus material or record participants during your research experiments.
Different types of camera can be used for different purposes. When in doubt, ask the TSG which camera is most appropriate for your situation.

Aside from technical suitability, it is also very important to consider data privacy and protection when choosing a type of camera for research purposes, especially when recording outside of our lab environment. Always talk to your data officer/steward/person before starting your project. They can advise you on the type of recording media you are allowed to use and/or protocols to follow to ensure sensitive data isn't leaked.


= Camera Types =
Below is an overview of available cameras within our faculty. Click on the individual pages for more information.

== Ipods ==
{{see also|Ipod}}
The TSG recommends the use of Ipods for general observational recording of research participants. Most people will know how to operate the camera on their smartphone, so setting up and using the iPod should be familiar and easy. Our iPods are passcode-protected, providing an extra layer of data protection in case the device gets stolen or lost.

'''Pros:''' Ease of use, data protection

'''Cons:''' Limited options, image & audio quality

== Webcams ==
{{see also|Elgato Facecam|OBS Studio#Webcam}}
Webcams can be used to stream and record video directly to a [[Computers|lab computer]] or laptop. This is helpful in situations where you wish to link/sync video data to other measurements, and/or to process the video data in real-time.

'''Pros:''' Ease of use, real-time monitoring

'''Cons:''' Limited options, image & audio quality

== Camcorders ==
{{see also|Camcorder}}
(High-end) camcorders are primarily used for recording stimuli material, or in cases where high image quality is required. Due to their larger sensor size and more advanced control over shutter speed, aperture, etc., camcorders can offer a much higher image quality than other cameras listed on this page, especially in low-light conditions.

'''Pros:''' Image quality, image controls

'''Cons:''' Ease of use

== 360 Degree Cameras ==
{{see also|Insta360 X3}}
360 degree cameras are special in that they can record a 360 degree view around them. You can use a 360 degree camera to create unique stimuli material, or in situations where you wish to record multiple subjects at once and placing multiple normal cameras is not an option.

'''Pros:''' Unique 360 degree view

'''Cons:''' Data security, file sizes, special editing software required

== Surveillance Cameras ==
{{see also|Surveillance Camera}}
Surveillance cameras are, at least in our case, effectively webcams with a network connection. They are primarily used for monitoring only (not recording).

'''Pros:''' Ease of use, real-time monitoring

'''Cons:''' Limited options, image quality

== Motion Capture Cameras ==
{{see also|Qualisys|Optotrak}}
Motion capture cameras are highly specialized cameras used for tracking optical markers. What makes these cameras special is their global shutter (as opposed to a rolling shutter found in most other cameras, which is much cheaper but can create [https://en.wikipedia.org/wiki/Rolling_shutter distortions]), and their sensitivity to the infrared spectrum (wherein motion capture markers are visible).
While it is possible to use some of our [[Qualisys]] cameras for recording regular video, it is not advised for any purposes other than motion capture.

'''Pros:''' Global shutter, high-speed marker tracking

'''Cons:''' Everything else

Camcorders are video recording devices used to create stimuli and/or record participant behavior during research experiments. In an effort to standardize video recording formats and control interfaces, the TSG has adopted the Canon Legria and XA/XF ranges of camcorders for use in our research labs (effective 2019). For simple, more user-friendly video recordings, you can use [[Ipod|iPods]]

==Usage==
===Observation===
The most common use of our camcorders is to record participant behavior in our labs. Be aware of your recording settings when filming many participants for many hours: the higher the resolution, framerate and bitrate, the larger the file size. Large files may take a long time to transfer and backup, and will cost the faculty a lot of server storage space when archived in Workgroup folders and Data repositories. The TSG advices the following settings for general purpose recordings for an optimal quality to file-size ratio, as well as for easy importing in any video coding software:
{| class="wikitable"
|-
| Format || MP4
|-
| Resolution || 1280 * 720 pixels (720p)
|-
| Framerate || 25 fps (progressive)
|-
| Bitrate || 4 Mbps (for h264 codec)
|-
|}

If you wish to record highly detailed movements, or retain more detail over larger distances, increase the resolution and bitrate. In most cameras these values are linked. Check the user manual or our quick start guide for your camera model to see how to adjust these settings.

===Stimuli Recording===
If you wish to use our camcorders to record video for creating stimuli, please contact [[Erik van den Berge]].

Log in to the computer that is there with your U/E/S number. Then you can log out again. On the computer there is a gray sticker with a number that starts with C, remember this number!

===Mouse Sensitivity===
You can change the sensor sensitivity of our Logitech mice to change how fast the pointer moves across the screen with every inch traveled. This is measured in dots per inch (DPI).
Press the DPI button below the scroll wheel to cycle through presets. A notification will pop up on screen telling you the current DPI level. Warning: notification may be delayed if you press the button multiple times!

If you want to set the mouse sensitivity at a custom DPI value, or if you wish to prevent participants from changing the sensitivity (accidentally or otherwise), please contact the TSG.

Note: this is completely independent from the pointer speed setting in Windows Settings. That slider should ALWAYS be set to 6 (the middle position), as any other value may introduce pointer acceleration, which is almost never wanted. "Enhance pointer precision" should be off for the same reason.
