Bug Report Remuxing from MKV to MP4 causes constant framerate to change to variable

[TheUntamedVoid]

Hi all,

I've only seen this posted a couple times on these forums, and those threads seem dead, so I thought I would post again with some detail of my own.

I have version 22.0.2 of OBS Studio x64 to record gameplay footage in CBR via the MKV file format. Playing that file back in Premiere Pro works fine, no desyncs - but if I remux (or record directly) to MP4, the file will be read as variable in both MediaInfo and Premiere Pro with a small portion of the video recording missing at the end of the playback and audio out of sync throughout the recording.

NOTE: Sometimes, the remuxed MP4 file will play fine, no desync, but a majority of the time it will have the problems stated above.

I have read up that this is a possible bug with FFmpeg but was wanting to see if anyone here has found a stable workaround?

Thanks for reading,
Dylan

i have the same problem. i'm converting from MKV to MP4 with OBS itself tho. In mediainfo it reads as CBR, as it should. doesnt happen to all the files, only to a few. i think that must be some premiere issues, and not OBS tho. VLC plays the files correctly synced.
