Question / Help Conversion mkv to mp4

[teolona]

I used OBS to record a video using a camera connected to my laptop through the Blackmagic intensity shuttle. The video recording in the mkv format is perfect, but when I convert it to mp4 (using OBS's tool) it looses audio/video sync. What can I do to fix the problem?

Try with Avidemux.

First open your ".mkv" file and set both "Audio Output" and "Video Output" options to "Copy". Then select "MP4 Muxer" as and output format and save the video.
