Last updated: 20 August 2026 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. DASH video Resolution AV1 HDR (HFR) AV1 HFR AV1 VP9.2 HDR (HFR) VP9 HFR VP9 H.264 HFR H.264 VP8 MP4 MP4 MP4 WebM WebM WebM MP4 MP4 WebM 4320p 702 402/571 272 138 2160p 701 401 337 315 (313) (305) (266) 1440p 700 400 336 308 (271) (304) (264) 1080p 699 399/721 335 303 248/356 299 137 170 720p 698 398 334 302/612 247 298 136/214 169 480p 697 397 333 244 135 168 360p 696 396 332 243 134 167 240p 695 395 331 242 133 144p 694 394 330 278/598 160/597 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 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, 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) 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.
