This is 10bit AV1 1080p encode using high quality settings.
Because this is AV1 codec, and because it uses 10bit, it WILL be hard to decode on weaker machines, so expect some framedrops.
Make sure your preferred media player is using latest Dav1d decoder version, with time and improvements to the decoder playback will improve dramatically.
