Anyway to import Matroska .mkv files?

For some lame-brained reason OBS defaults to the .mkv format when recording video, so I now have a couple of hours of footage in a few .mkv files. Is there any way to load these files into DaVinci Resolve?

I suspect I'm going to have to use something like Handbrake to transcode them into something usable. A possible further complication is that I was trying to capture them with an H.265 hardware encoder. Not sure if Handbrake can handle that...

OBS has a remix function built in (Files -> Remix recordings) that does this for you automatically

Or you can just change the default output format (subject to caveats it warns you about when you change the default setting)

No need for handbrake / etc

Don't recompress with Handbrake, just re-wrap into .MOV or .MXF. A program like Shutter Encoder can do that.
It's a pretty fast process if your source and destination are on different media, preferably SSD.

I always recommend hardware recorders for screen capture you intend to edit. They typically offer editing friendly options like DNx and ProRes, whereas software normally doesn't.

OBS does, you just need to choose it. Planning of your workflow should be the start of your project, not recording.

Thanks for this, you probably just saved me a few hours of transcoding. I've remuxed video before with FFmpeg but it was rather difficult getting the syntax just right.

I'm new to this, so I'm still making noob mistakes, and likely will for a while...

That's why I suggested Shutter Encoder, it's actually just a front-end for ffMPEG, but a nice one.

Just an aside that Shutter Encoder is an absolutely amazing, and underrated app. It can also do Cinedeck style insertions into existing Quicktime masters (I really wish Resolve could do this, natively), as well as auto detect “Media Offline” screens in masters for all the major NLEs. It has an ugly-AF UI, but it’s quickly become one of my go to Swiss-army knife utility apps for post-production.
