WebAug 1, 2016 · The only way with your method is to completely write the video using OpenCV by generating all of the frames, then when you're done you use FFMPEG to compress the video by altering the bitrate. However, it's possible to directly send RGB data to FFMPEG using pipes but that does not use OpenCV. – rayryeng. Aug 2, 2016 at 2:34.

WebMay 23, 2024 · Note that when -maxrate and -bufsize limit the max bit rate, by necessity the average bit rate will be lower, so the video will undershoot the target size by as much as 5-10% in my tests (on a 20s video at various target sizes).
