by extension for the extensions aac, m4a,
mp3, mp4, ogg, wav, webm. You can also use
the special names "best", "bestvideo",
- "bestaudio", "worst". By default, youtube-
- dl will pick the best quality. Use commas
- to download multiple audio formats, such as
- -f
+ "bestaudio", "worst". You can filter the
+ video results by putting a condition in
+ brackets, as in -f "best[height=720]" (or
+ -f "[filesize>10M]"). This works for
+ filesize, height, width, tbr, abr, and vbr
+ and the comparisons <, <=, >, >=, =, != .
+ Formats for which the value is not known
+ are excluded unless you put a question mark
+ (?) after the operator. You can combine
+ format filters, so -f "[height <=?
+ 720][tbr>500]" selects up to 720p videos
+ (or videos where the height is not known)
+ with a bitrate of at least 500 KBit/s. By
+ default, youtube-dl will pick the best
+ quality. Use commas to download multiple
+ audio formats, such as -f
136/137/mp4/bestvideo,140/m4a/bestaudio.
You can merge the video and audio of two
formats into a single file using -f <video-
