• 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

Rare videos of AV1

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)

https://www.youtube.com/watch?v=r-X4DJxT6gY (4 years ago and unlisted video, got couple months to get AV1)

Duplicate video IDs

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:

30 fps video

60 fps video

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
788	MP4	AV1	Saves sizes and quality little than VP9, but some videos only

Credits and special thanks

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.

Fixed it, moving 214 format from VP9 to H.264, @aokin1999. Thanks! :)

• Martin Eesmaa

I think I found something rare on Grover Washington Jr. - Just The Two Of Us a couple of itag codes which has 256kbs audio but for free not pay per listen in m4a format but the picture is totally black screen in my media player and that black picture has an AV1 codec according to YouTube the stats for nerds itself so maybe AV1 doesn't mix well with 256 m4a or maybe my video l=playing sofeware is too out of date to get a picture.

I checked the itags out because I was curious why did my software which uses m3u8 give me a black screen with m4a 256 for free as well on that itag and these are the 2 itags that 256 free had.

616 1080 m3u8 Rare 256 m4a Free Audio Broken Picture Black Screen
290 1080 m3u8 Rare 256 m4a Free Audio Broken Picture Black Screen

And this is what the non formats code scanning gave me on the same video for interesting comparing

251 1080 Sound Code which is normally VBR 128-160 vorbis
399 1080 Picture Code
398 720 Picture Code
397 480 Picture Code
396 360 Picture Code
395 240 Picture Code
394 144 Picture Code

So all the picture codes were all in a row but the sound code lesser bitrate than the in free mode so 256 free m4a is still on m3u8 but not on http.

Very fun that. The video with the black screen was 128 bitrate and the m4a was 256 on the itag but it also had problems even downloading in my software becasue it was so exotic the side panel download wouldn't even trigger but if you clicked hard download from the menu it got that verson out of it's m3u8 itag not like it needs the artwork on the file to listen to the track anyway.

File also had special enhanced audio on YouTube which I can't access but maybe those itags was it but if you have those itags you can get it for free it's one thats not blocked on my test download either way from those 616 and 290 itags.

The weird things you do to find out why you got a 256 file when you shouldn't be getting it for free.

Edit: Interesting 616 and 290 are not in your list of m3u8 formats so there you go it is legitlly exotic this free 256kbs with a blank picture itag but what is the code for free 256 when you convert that from m3u8 to http itag codes as it's probably an itag google never wanted us to learn about and more snaggers use http than m3u8 only the one I use for radio probably even uses it?

We really need the full list of these http to m3u8 conversions as well as m3u8 to http for those 2 codes as you can really analyse it for fun the weirdness of exotic video formats.

I think you guys should rethink making yt-dlp command line only as MSDOS is really out of date now and not everyone knows how to use it anymore we need you to make a GUI 32/64-Bit for your software as well Martin so we can have a play without having to be bothered about using the command line which is out of date and shouldn't really be used for software anymore.

YouTube Video and Audio Downloader (WebEx) by [feller] used to be a GUI available for yt-dlp with FFMPEG features available but available for your Firefox but feller hasn't updated it in years and the codes as well as URL's database is so out of date his GUI doesn't work for us anymore but it shows you how much better if yt-dlp stepped away from command line coding into a safe to use browser GUI yet along Windows GUI, Linux and Mac non browser and the experience is so much better than having to use out of date command lines and dare I say it better than Windows GUI's becasue that type of GUI is in your browser.

Command line mode within the extension as well would be good though for those things you actaully need it for but yeah we need a better experience for those who can't code or too lazy to type it in.

616-96=520
290-96=194

So the other formats flipped to +96 m3u8 might be this

251+96=347
399+96=495
398+96=494
397+96=493
396+96=492
395+96=491
394+96=490

Thats if it's +96 -96 like the rest of the conversions in the smaller m3u8 codes list we have to begin with it really needs to be updated to full though if +96 -96 is all there is to all the conversion like it looks to be if m3u8 was fully updated there wouldn't be so much issue in m3u8 relying software for the speed of the protocol software detecting stuff at the moment.

If going by the rest of the list might be the m3u8 to http conversion so if they are the conversions they are not even on the list neither so it really is new and exotic and so far only encountered on a YouTube Music 80s file becasue of having to mess around for radio and found out that it was exotic.

Edit: Maybe thats not so simple as +96 there are some +300 conversiosn as well in the existing lists. lol

Sorry about that I do yak a lot when nerding out.

@TEOL85 🙄
251 is Opus ~128kbps (vorbis used other ids muxed with vp8, and those are deprecated, tho there are still a few standalone vp8 encodes)
616 is m3u8 id for 1080p Premium VP9 (356 https id) thats usually listed on popular 1080p videos (higher resolutions wont have premium formats)

270 (137) and 290 are both H.264/AVC 1080p, m3u8 rates are always artifically higher than https but consistent in a same video so probaly 290 is an higher bitrate variant of 137, so maybe it is 216. All these are video only, including 616(356). Only current format with both audio and video is 18 if i'm not wrong.

All the rest you say I just don't understand it. YT-DLP is commandline, and python, though there are .exe builds for windows. For some reason I can't download the 290 stream (but 270 doesn't give any problem). Maybe I would need to use some specific options but I don't have patience or time now, so, anyone else try to get it (and get the equivalent ID if possible).

Last edit (yeah I did a lot): I realized there are more avc formats, so I dunno, maybe a lot of different encodes (higher quality? tho it's still image so i doesnt make much sense) or just duplications.
