You can also use special names to select particular edge case formats:
- - `best`: Select the best quality format represented by a single file with video and audio.
- - `worst`: Select the worst quality format represented by a single file with video and audio.
- - `bestvideo`: Select the best quality video-only format (e.g. DASH video). May not be available.
- - `worstvideo`: Select the worst quality video-only format. May not be available.
- - `bestaudio`: Select the best quality audio only-format. May not be available.
- - `worstaudio`: Select the worst quality audio only-format. May not be available.
+ - `b*`, `best*`: Select the best quality format irrespective of whether it contains video or audio.
+ - `w*`, `worst*`: Select the worst quality format irrespective of whether it contains video or audio.
+
+ - `b`, `best`: Select the best quality format that contains both video and audio. Equivalent to `best*[vcodec!=none][acodec!=none]`
+ - `w`, `worst`: Select the worst quality format that contains both video and audio. Equivalent to `worst*[vcodec!=none][acodec!=none]`
+
+ - `bv`, `bestvideo`: Select the best quality video-only format. Equivalent to `best*[acodec=none]`
+ - `wv`, `worstvideo`: Select the worst quality video-only format. Equivalent to `worst*[acodec=none]`
+
+ - `bv*`, `bestvideo*`: Select the best quality format that contains video. It may also contain audio. Equivalent to `best*[vcodec!=none]`
+ - `wv*`, `worstvideo*`: Select the worst quality format that contains video. It may also contain audio. Equivalent to `worst*[vcodec!=none]`
+
+ - `ba`, `bestaudio`: Select the best quality audio-only format. Equivalent to `best*[vcodec=none]`
+ - `wa`, `worstaudio`: Select the worst quality audio-only format. Equivalent to `worst*[vcodec=none]`
+
+ - `ba*`, `bestaudio*`: Select the best quality format that contains audio. It may also contain video. Equivalent to `best*[acodec!=none]`
+ - `wa*`, `worstaudio*`: Select the worst quality format that contains audio. It may also contain video. Equivalent to `worst*[acodec!=none]`
-For example, to download the worst quality video-only format you can use `-f worstvideo`.
+For example, to download the worst quality video-only format you can use `-f worstvideo`. It is however recomended to never actually use `worst` and related options. See [sorting formats](#sorting-formats) for more details.
-If you want to download multiple videos and they don't have the same formats available, you can specify the order of preference using slashes. Note that slash is left-associative, i.e. formats on the left hand side are preferred, for example `-f 22/17/18` will download format 22 if it's available, otherwise it will download format 17 if it's available, otherwise it will download format 18 if it's available, otherwise it will complain that no suitable formats are available for download.
+If you want to download multiple videos and they don't have the same formats available, you can specify the order of preference using slashes. Note that formats on the left hand side are preferred, for example `-f 22/17/18` will download format 22 if it's available, otherwise it will download format 17 if it's available, otherwise it will download format 18 if it's available, otherwise it will complain that no suitable formats are available for download.
If you want to download several formats of the same video use a comma as a separator, e.g. `-f 22,17,18` will download all these three formats, of course if they are available. Or a more sophisticated example combined with the precedence feature: `-f 136/137/mp4/bestvideo,140/m4a/bestaudio`.
+You can merge the video and audio of multiple formats into a single file using `-f <format1>+<format2>+...` (requires ffmpeg or avconv installed), for example `-f bestvideo+bestaudio` will download the best video-only format, the best audio-only format and mux them together with ffmpeg/avconv. If `--no-video-multistreams` is used, all formats with a video stream except the first one are ignored. Similarly, if `--no-audio-multistreams` is used, all formats with an audio stream except the first one are ignored. For example, `-f bestvideo+best+bestaudio` will download and merge all 3 given formats. The resulting file will have 2 video streams and 2 audio streams. But `-f bestvideo+best+bestaudio --no-video-multistreams` will download and merge only `bestvideo` and `bestaudio`. `best` is ignored since another format containing a video stream (`bestvideo`) has already been selected. The order of the formats is therefore important. `-f best+bestaudio --no-audio-multistreams` will download and merge both formats while `-f bestaudio+best --no-audio-multistreams` will ignore `best` and download only `bestaudio`.
+
+## Filtering Formats
+
You can also filter the video formats by putting a condition in brackets, as in `-f "best[height=720]"` (or `-f "[filesize>10M]"`).
The following numeric meta fields can be used with comparisons `<`, `<=`, `>`, `>=`, `=` (equals), `!=` (not equals):
Any string comparison may be prefixed with negation `!` in order to produce an opposite comparison, e.g. `!*=` (does not contain).
-Note that none of the aforementioned meta fields are guaranteed to be present since this solely depends on the metadata obtained by particular extractor, i.e. the metadata offered by the video hoster.
+Note that none of the aforementioned meta fields are guaranteed to be present since this solely depends on the metadata obtained by particular extractor, i.e. the metadata offered by the video hoster. Any other field made available by the extractor can also be used for filtering.
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.
-You can merge the video and audio of two formats into a single file using `-f <video-format>+<audio-format>` (requires ffmpeg or avconv installed), for example `-f bestvideo+bestaudio` will download the best video-only format, the best audio-only format and mux them together with ffmpeg/avconv.
-
Format selectors can also be grouped using parentheses, for example if you want to download the best mp4 and webm formats with a height lower than 480 you can use `-f '(mp4,webm)[height<480]'`.
-Since the end of April 2015 and version 2015.04.26, youtube-dlc uses `-f bestvideo+bestaudio/best` as the default format selection (see [#5447](https://github.com/ytdl-org/youtube-dl/issues/5447), [#5456](https://github.com/ytdl-org/youtube-dl/issues/5456)). If ffmpeg or avconv are installed this results in downloading `bestvideo` and `bestaudio` separately and muxing them together into a single file giving the best overall quality available. Otherwise it falls back to `best` and results in downloading the best available quality served as a single file. `best` is also needed for videos that don't come from YouTube because they don't provide the audio and video in two different files. If you want to only download some DASH formats (for example if you are not interested in getting videos with a resolution higher than 1080p), you can add `-f bestvideo[height<=?1080]+bestaudio/best` to your configuration file. Note that if you use youtube-dlc to stream to `stdout` (and most likely to pipe it to your media player then), i.e. you explicitly specify output template as `-o -`, youtube-dlc still uses `-f best` format selection in order to start content delivery immediately to your player and not to wait until `bestvideo` and `bestaudio` are downloaded and muxed.
+## Sorting Formats
+
+You can change the criteria for being considered the `best` by using `-S` (`--format-sort`). The general format for this is `--format-sort field1,field2...`. The available fields are:
+
+ - `video`, `has_video`: Gives priority to formats that has a video stream
+ - `audio`, `has_audio`: Gives priority to formats that has a audio stream
+ - `extractor`, `preference`, `extractor_preference`: The format preference as given by the extractor
+ - `lang`, `language_preference`: Language preference as given by the extractor
+ - `quality`: The quality of the format. This is a metadata field available in some websites
+ - `source`, `source_preference`: Preference of the source as given by the extractor
+ - `proto`, `protocol`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8-native` > `m3u8` > `http-dash-segments` > other > `mms`/`rtsp` > unknown > `f4f`/`f4m`)
+ - `vcodec`, `video_codec`: Video Codec (`av01` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other > unknown)
+ - `acodec`, `audio_codec`: Audio Codec (`opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac3` > `dts` > other > unknown)
+ - `codec`: Equivalent to `vcodec,acodec`
+ - `vext`, `video_ext`: Video Extension (`mp4` > `flv` > `webm` > other > unknown). If `--prefer-free-formats` is used, `webm` is prefered.
+ - `aext`, `audio_ext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other > unknown). If `--prefer-free-formats` is used, the order changes to `opus` > `ogg` > `webm` > `m4a` > `mp3` > `aac`.
+ - `ext`, `extension`: Equivalent to `vext,aext`
+ - `filesize`: Exact filesize, if know in advance. This will be unavailable for mu38 and DASH formats.
+ - `filesize_approx`: Approximate filesize calculated the manifests
+ - `size`, `filesize_estimate`: Exact filesize if available, otherwise approximate filesize
+ - `height`: Height of video
+ - `width`: Width of video
+ - `res`, `dimension`: Video resolution, calculated as the smallest dimension.
+ - `fps`, `framerate`: Framerate of video
+ - `tbr`, `total_bitrate`: Total average bitrate in KBit/s
+ - `vbr`, `video_bitrate`: Average video bitrate in KBit/s
+ - `abr`, `audio_bitrate`: Average audio bitrate in KBit/s
+ - `br`, `bitrate`: Equivalent to using `tbr,vbr,abr`
+ - `samplerate`, `asr`: Audio sample rate in Hz
+
+All fields, unless specified otherwise, are sorted in decending order. To reverse this, prefix the field with a `+`. Eg: `+res` prefers the smallest resolution format. Additionally, you can suffix a prefered value for the fields, seperated by a `:`. Eg: `res:720` prefers larger videos, but no larger than 720p and the smallest video if there are no videos less than 720p. For `codec` and `ext`, you can provide two prefered values, the first for video and the second for audio. Eg: `+codec:avc:m4a` (equivalent to `+vcodec:avc,+acodec:m4a`) sets the video codec preference to `h264` > `h265` > `vp9` > `av01` > `vp8` > `h263` > `theora` and audio codec preference to `mp4a` > `aac` > `vorbis` > `opus` > `mp3` > `ac3` > `dts`. You can also make the sorting prefer the nearest values to the provided by using `~` as the delimiter. Eg: `filesize~1G` prefers the format with filesize closest to 1 GiB.
+
+The fields `has_video`, `extractor_preference`, `language_preference`, `quality` are always given highest priority in sorting, irrespective of the user-defined order. This behaviour can be changed by using `--force-format-sort`. Apart from these, the default order used by youtube-dlc is: `tbr,filesize,vbr,height,width,protocol,vext,abr,aext,fps,filesize_approx,source_preference,format_id`. Note that the extractors may override this default order (currently no extractor does this), but not the user-provided order.
+
+If your format selector is `worst`, the last item is selected after sorting. This means it will select the format that is worst in all repects. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-f best -S +size,+br,+res,+fps`.
+
+**Tip**: You can use the `-v -F` to see how the formats have been sorted (worst to best).
+
+## Default Format Selection
+
+Since the end of April 2015 and version 2015.04.26, youtube-dlc uses `-f bestvideo+bestaudio/best` as the default format selection (see [#5447](https://github.com/ytdl-org/youtube-dl/issues/5447), [#5456](https://github.com/ytdl-org/youtube-dl/issues/5456)). If ffmpeg or avconv are installed this results in downloading `bestvideo` and `bestaudio` separately and muxing them together into a single file giving the best overall quality available. Otherwise it falls back to `best` and results in downloading the best available quality served as a single file. `best` is also needed for videos that don't come from YouTube because they don't provide the audio and video in two different files. Note that if you use youtube-dlc to stream to `stdout` (and most likely to pipe it to your media player then), i.e. you explicitly specify output template as `-o -`, youtube-dlc still uses `-f best` format selection in order to start content delivery immediately to your player and not to wait until `bestvideo` and `bestaudio` are downloaded and muxed.
If you want to preserve the old format selection behavior (prior to youtube-dlc 2015.04.26), i.e. you want to download the best available quality media served as a single file, you should explicitly specify your choice with `-f best`. You may want to add it to the [configuration file](#configuration) in order not to type it every time you run youtube-dlc.

+$ youtube-dlc -S 'res:720,fps'
+
+
+
+# Download the video with smallest resolution no worse than 480p,
+# or the video with the largest resolution available if there is no such video,
+# prefering better codec and then larger total bitrate for the same resolution
