I assume we'll be able to turn on HDR support even in stable Firefox through config flags once the underlying code reaches beta and release versions, but it won't be enabled by default for a while I imagine.

I really think 90% of Internet connections should have 0 KB/s upload rate

YouTube's recommended upload bitrate is imo way too low, especially in this case.

Uploading Exanima footage at that bitrate results in an awfully blocky and compressed image as soon as there's any movement.

The image quality improvement from a much higher bitrate is MASSIVE.

Importing the remuxed video seems to have fixed it for me.

Basically, that mkvmerge argument sets the video's framerate to exactly 60 fps instead of the fractional framerate captured by OBS.

It seems like Resolve doesn't like framerates that aren't exactly 60 fps, just like OBS.

It's kind of complex to type out here, but I could do it successfully for 59.999725, for example. It came out to be 654537/10909 with a remainder of .000025.

Basically, I ended up with 11,000 after multiplying by 1000, 2000, etc until I got the biggest or smallest remainder, then worked backwards.

I get this too, and I think everyone does, to varying degrees. I could fix it in OBS using the fractional fps recording trick. My real refresh rate was 60.000285, so I now record at 210541/3509 fps.

Apparently capture cards with buffering enabled don't suffer from this issue.

FYI: The kind of stutter I'm talking about manifests somewhat randomly in the recorded footage, even if the game was a perfect 60 fps the whole time.

It might take up to 15-20 minutes (or even longer) of recording for the stutter to show up.
