FFmpeg is an open-source command-line tool to convert audio and video files. <br/>

We know command-line tools can seem scary! But conversion software GUIs (graphical user interfaces) 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~~

#Go to https://ffmpeg.org/download.html

#Unpack the 7z/zip file anywhere you like

#Under "Get packages & executable files", select the Windows logo and follow one of the links below (''gyan.dev'' is most common)

#Download the latest ''ffmpeg-release-essentials'' .7z or .zip file.<ref>The FFmpeg "essentials" version should be fine for most purposes; use "full" version for more obscure/obsolete/experimental formats</ref>

#Unpack the 7z/zip file anywhere you like.

#Add ffmpeg to Windows' Environment Variables:

## Open the start menu and start typing "Environment Variables"

<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.

⚠️If you use <code>-vcodec copy</code> to trim without re-encoding, FFmpeg can only cut to the nearest keyframe, so the output may not be exactly the same length as specified.
