Also known as itag or format codes and way back they could be specified with the fmt parameter (e.g. &fmt=22) used to be on website address bar after YouTube Video ID, (deprecated?).
Depending on the age and/or popularity of the video, not all formats will be available.

- 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 356 & 712, it is the only YouTube premium video format and requires your YouTube account subscribed with Premium subscription to pass cookies file. Format 356 is connected to format 616 (available on yt-dlp, not 356) of M3U8.
- At format 214, some rare videos were encoded and it is linked from format 379 (available on yt-dlp, not 214) of M3U8 can be found this video
- For some marked parenthesis format like
(271)means that it may be claimed by someone without video link, was old superseeded format from YouTube or something else. I honestly don't know yet... - Please take note that YouTube started to use AI for use super resolution (announced it in late 2025, Q4) from low quality videos (e.g. old nostalgia videos) into high quality videos for some resolutions selected. For example source video resolution is 240p and it has extended resolutions up to 720p and after format adds suffix
-sr. Most videos are not super resolution formats available, some videos may have. Example video
Some rarely videos may get AV1 video codec for low views or/and upload date less than 24 hours for average 10 minutes duration video.
It could be luck or/and conveniency for YouTube's quiet decision.
Here is sample videos:
https://www.youtube.com/watch?v=BizgNeskJ6o (20 hours ago and at least 50 views, reported on 26.06.2025, later it was deleted it)
https://www.youtube.com/watch?v=r-X4DJxT6gY (4 years ago and unlisted video, got couple months to get AV1)
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.
Also even special thanks, gamer191 to report linked M3U8 codes to common codes.

Examples of two videos:
Extra video formats of 72p & 608p
Formats of 228, 779, 780 and 788 were rarely encoded to some YouTube videos, the video resolution is 1080x608 and always under 30 FPS:
But for format 228 is 72p quality and only 6 FPS.
| Code | Container | Video Codec | Explanations |
|---|---|---|---|
| 228 | MP4 | AVC | Like thumbnail quality with slow FPS |
| 779 | WebM | VP9 | Efficiency possible saving data for mobiles |
| 780 | WebM | VP9 | Best quality possible of VP9 than format 779 |
| 787 | WebM | AV1 | Saves more sizes with quality than VP9, some videos only |
| 788 | MP4 | AV1 | Saves sizes and quality little than VP9, but some videos only |

Thanks to @GammaBoost for finding three formats (779,780,788)!
Thanks to @aokin1999 for finding a format 228!

Update yt-dlp via pip (recommended):
pip install yt-dlp -U
Since late 2025, YouTube has given sleep time delay before downloading videos, this may be delay for pre-download method, even cannot download a video with age-restricted method trying to bypass it...
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.
mscalindt for finding format 379 that was undocumented before I updated it now. It was linked to format 214 of DASH video.
Manwithpants812 for finding missing format 356 due to undocumented which is related to format 616.
Low-power for claiming the experience finding of format 22 removed since 21 June 2024.
Aokin1999 for finding spot fixes & corrections, also pretty cool with fork gist :)
