Just been looking at the available playback options for this video <https://www.youtube.com/watch?v=_u7d1wNDOyc> (rCLCasanovarCY by L.A.B.,
if you donrCOt want to have to click to find out ;)). youtube-dlrCarCOs rCL-FrCY
option reports, among other things, the following:

248 webm 1920x1080 25 roe 26.86MiB 1019k https roe vp09.00.40.08 1019k video only 1080p, webm_dash
313 webm 3840x2160 25 roe 263.14MiB 9986k https roe vp09.00.50.08 9986k video only 2160p, webm_dash
571 mp4 7680x4320 25 roe 316.53MiB 12013k https roe av01.0.16M.08 12013k video only 4320p, mp4_dash

ThatrCOs 2K, 4K and 8K video options.

Note the 10|u jump in the video bitrate going from 2K to 4K, for only a
4|u jump in the number of pixels. Then 8K (another 4|u increase in
pixels) is only about another 20% on top of that.

OK, so the 8K version is using a different codec. But it seems to me
either the 4K one is at a needlessly high bitrate, or alternatively
the 2K one is set too low. I suspect the former.

rCayt-dlp, actually, since the original youtube-dl is now defunct. But I
have it aliased to the command rCLyoutube-dlrCY, for old timerCOs sake. ;)
