Pre-Note: This isn't supposed to be very useful or clean yet. I just wanted to organize this in my own and I'm trying to do it. :>
Note: This is all almost full YouTube ID informations. Original owner goes to AgentOak, and thanks for most updates to Martin Eesmaa and the incredible internet community. :>

Also known as itag or format codes and way back they could be specified with the fmt parameter (e.g. &fmt=22).
Depending on the age and/or popularity of the video, not all formats will be available.

- HD stands for "High Resolution", it includes all 720p and higher resolutions.
- HFR stands for "High Framerate", which means up to 60 FPS, whereas non-HFR is limited to 30 FPS.
- HDR stands for "High Dynamic Range", which means higher range for lights, shadows and colors. HDR format used by YouTube is the open HDR10 standard (10-bit sampling + static metadata).
- 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 were only provided for 360°
- At the moment, AV1 variants are only provided for popular videos
- All AV1 HD/HDR formats and VP9 HDR can also have standard framerates
- AV1 4320p: Format 571 has roughly 50% higher bitrate than 402. Sometimes only one of them is offered, sometimes both.571 can be seen on this video.
- VP8 can be found this video.
- Formats 616 and 721: These are the only YouTube premium video formats. 721 is still on experimental stage so it isn't fully available. Anyway, premium formats are only applied for popular videos.
- 144p Low: Formats 598 and 597 were the lowest quality offered for mobile clients and had half the framerate of standard non-HFR formats, these aren't provided anymore as DASH video. Only VP9 144p Low is still offered for m3u8 HLS (602).
Those duplicate video IDs of m3u8 as Apple Native HLS are linked to common numbers, they're not just rare numbers.
270 (m3u8) == 137 (https) are same video quality, but different protocol.
Thanks, dtlnor for explanation of equalation video IDs.

These are the frame thumbnails that appear when moving the cursor over the progress bar. So they're called storyboard (sb) too. These are numbered from sb0 (max resolution of the preview) up to sb2/sb3. The highest number has always the lowest resolution. Format sb3 is only used for 16:9 and 21:9 aspect ratios (likely). If original res is low then Youtube won't use the highest sb2/3 ids. It's variable depending on aspect ratios and resolutions, so just check it with yt-dlp in your video. It's a total hell to explain this and it's useless as nobody cares about storyboard. Last detail before the table, very short videos (non-ytshorts, and likely under 15 seconds) may not have any storyboard.
| Format\Aspect Ratio | 4:3 | 3:2 | 16:10 | 16:9 | 1.85:1 | 21:9 | 2.35:1 | 2.39:1 | 16:6 | 32:9 |
|---|---|---|---|---|---|---|---|---|---|---|
| sb(max number) | 48x27 | 48x27 | 48x27 | 48x27 | 48x27 | 48x27 | 48x27 | 48x27 | 48x27 | 48x27 |
| sb(max number - 1) | 60x45 | 67x45 | 70x45 | 80x45 | 83x45 | 105x45 | 105x45/106x45 | 107x45 | 120x45 | 180x45 |
| sb(max number - 2) | 120x90 | 135x90 | 141x90 | 160x90 | 166x90 | 210x90 | 211x90/213x90 | 214x90 | 240x90 | 320x90 |
| sb(max number - 3) | ???/320x180 | 420x180 |
Most formats are easy to find out, so no samples for every one.
16:6 format sample here
Different approximated "2.35:1" samples here and here
This is a total pain, for <16:9 the height rules, and for >16:9 the width rules the aspect
IDK what other aspect ratios are allowed by YouTube and which will be resized. An entire table of all could be enormous if there are even more than those listed... :<
Formats of 779, 780 and 788 were rarely encoded to some YouTube videos, the video resolution is 1080x608 and capped to 30 FPS (no HFR found yet, maybe there is not).
But for format 228 is 72p quality and only up to 7.5 FPS (probably).
| Code | Container | Video Codec | Explanations |
|---|---|---|---|
| 228 | MP4 | AVC | Like thumbnail quality with slow FPS (1/4 of standard framerate), only m3u8 ID available |
| 779 | WebM | VP9 | Efficiency possible saving data for mobiles |
| 780 | WebM | VP9 | Best quality possible of VP9 than format 779 |
| 788 | MP4 | AV1 | Saves sizes and quality little than VP9, but some videos only |

Thanks to @GammaBoost for finding three formats! Thanks to @aokin1999 for finding a format 228!

Special thanks for finding/fixing by:
qzmtch for finding missing 616 format
dtlnor for little interesting explanation of duplicate formats same
