   @alyx so initial test was h264 120fps grey10le clip that was 5 minutes, 689 Mbps, and 24.1 GiB in size.
   
   This help article seemed to suggest that 120fps might work:

   What YouTube spat out was yuv240, vp9, 60fps, 381 Mbps, 13.3 GiB
   
   YouTube seems to have done a good job preserving all of the noise at 4k. It's artifact city at the lower resolution.
   
   That's wild.
   
   What's also cool is you can see what each resolution is capped at. 1440p seems to be capped at 65 Mbps while 1080p appears to be capped at 10Mbps. It also shows how YouTube is phasing out h264. They really only put effort into their 1080p h264 stream which makes sense as it's likely the most popular of the h264 streams by far.
   
   I wonder if different frame rates have different bitrate caps.
   
   But yeah 4k seems to get crf with no vbv cutoff limit.
