Please find below the results of mediainfo in the Zoom-generated mp4 file. No, they stopped doing variable framerate some time ago to improve compatibility ( ). I was not able to find information on this matter. bitrate, or different CRF parameters), adjusting sound quality (1 channel, 32Khz sampling - as the original -, 64 Kbps) but I could not come close to the size or quality that the mp4 generated by zoom provided.Īny hint? Of course if anyone has information regarding the options that Zoom uses to generate the mp4 file, that would be a good first step.

I also reencoded it in 1920x1280, to save some space, using several options (avg. I then used Shotcut to make a nicer edited version, removing the same parts and adding a part of very short text sections. But the result is not really nice: no title for the lecture, no text noting that there was an initial discussion, a break, etc. of 260Mb (the part I cut had most of the movements / changes in the imace). I can edit it using another tool to remove the chunks that are not interesting, aligning to keyframes, and copying everything else. This conversion is quite efficient: 2-hour lecture (90% of it still slides) in 3008 x 1692 resolution is converted into a 390Mb mp4 (h264/aac) file that looks very good (text is sharp, transitions do now show artifacts), despite a low (video) bitrate of 364 kb/s.

As a recap, Zoom, a VC system, allows recordings of VC that are saved (locally or in the cloud) in some undisclosed format that their tools can convert into.
