- HFR stands for "High Framerate", which means up to 60 FPS, whereas non-HFR is limited to 30 FPS
- Non-HFR 1080p+ H.264 and VP9 variants are not provided for HFR videos anymore
- Same IDs are reused for 360° videos
- 1440p+ H.264 variants are only provided for 360° videos anymore
- At the moment, AV1 variants are only provided for popular videos
- All AV1 variants can be HDR (no separate non-HDR AV1 variants are offered)
- AV1 HFR High: High refers to the bitrate. These variants have ~3-4 times the bitrate of their normal counterparts. Additional side effect is providing AV1 HFR variants for low resolutions (<=480p). These variants are rare even among videos with AV1 variants. Found on this video.
- AV1 HFR 4320p: Format 571 has roughly 50% higher bitrate than 402. Sometimes only one of them is offered, sometimes both. Can be seen on this video.
- VP8 can be found this video.
- At format 616, it is the only YouTube premium video format.
Those duplicate video IDs of m3u8 as Apple Native HLS are linked to common numbers, not a rare numbers.
270 (m3u8) == 137 (https) are same video quality, but different protocol.
Thanks, dtlnor for explanation of equalation video IDs.

AgentOak (original owner) made YouTube list formats of video and audio ID especially with tips.
MartinEesmaa (forked owner) updated YouTube list formats for up to date.
Special thanks for finding/fixing by:
qzmtch for finding missing 616 format
dtlnor for little interesting explanation of duplicate formats same
r8420 for finding missing 612 format
Ciancy28 for finding high quality of Opus 256 kbps (format 774) in YT Music
joaquinito2070 for renaming youtube-dl to yt-dlp and fixing incorrect bitrates. Some commits were on it.
No, not all videos' format 18 are 128kbps. https://youtu.be/FAyKDaXEAgc (not a music video) is also 128kbps, but https://youtu.be/laFY-8vD9ig is 96kbps. Maybe it depends on video length.
