Video Codecs: Difference between revisions

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 frames, resulting in possible lag if your processor unit cannot keep up. For this reason, we advise using a constant bitrate.
