How to convert/remux mkv files to mp4 using OBS

Not all video editing programs support mkv files, but OBS Studio (Open Broadcaster Software) has a built-in way to convert (or, more accurately, “remux”) mkv files to mp4 files. Here’s how to do it:
Open OBS, click File, then Remux Recordings

This video was created using OBS Studio 24.0.1

Thank you so much for this. Straight to the point. Wish I knew this earlier because I was using a free online converter every time and if I knew this earlier it would've said me a lot of trouble and time. Great tutorial.

i have a lager file that i am trying to remux, however it keeps telling me that the remuxing is complete, however some files may be incomplete. Any help??

This is a literal life-saver! I usually just record my videos but never really edit them because finding a legit converter website and using it was just too much of a hassle. Thank you for showing me this! I'll be uploading more often now!
