Does the new Premiere no longer support .mkv files? I was working on a project and updated to the new edition and now all my .mkv files are gone and aren't showing up in my folders anymore. If .mkv files are gone for good, how can I convert the files I have into a supported format?

I think Adobe dropped MKV support with the release of CC2019.

You could use the free (and incredible) LosslessCut app to very easily turn your mkvs into MOVs or mp4s

Okay. For whatever reason, .mkv is the only format OBS Studio puts out, so do you know of any good alternatives to that? I'd ask their forums, but it's a living nightmare there.

Technically, it is supporting this file... just not the video part, which is generally more important to me than the audio.

So this video is Variable Frame Rate, which Premiere is notorious for not playing nice with (do not confuse VFR with Variable BIT Rate, VBR, which is fine). Unfortunately, OBS defaults to VFR. Can you try changing your OBS recording settings to Constant Frame Rate, CFR, record a small test, and see if you can get that file into Premiere?

Also, 3Mb/s video bitrate is on the low side. Are you okay with the quality of the video (when you can see it)?
