OUTPUT TEMPLATE

The -o option is used to indicate a template for the output file names while -P option is used to specify the path each type of file should be saved to.

tl;dr: navigate me to examples.

The simplest usage of -o is not to set any template arguments when downloading a single file, like in yt-dlp -o funny_video.flv "https://some/video" (hard-coding file extension like this is not recommended and could break some post-processing).

It may however also contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to Python string formatting operations, e.g. %(NAME)s or %(NAME)05d. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations.

The field names themselves (the part inside the parenthesis) can also have some special formatting:

Object traversal: The dictionaries and lists available in metadata can be traversed by using a dot . separator; e.g. %(tags.0)s, %(subtitles.en.-1.ext)s. You can do Python slicing with colon :; E.g. %(id.3:7:-1)s, %(formats.:.format_id)s. Curly braces {} can be used to build dictionaries with only specific keys; e.g. %(formats.:.{format_id,height})#j. An empty field name %()s refers to the entire infodict; e.g. %(.{id,title})s. Note that all the fields that become available using this method are not listed below. Use -j to see such fields
Addition: Addition and subtraction of numeric fields can be done using + and - respectively. E.g. %(playlist_index+10)03d, %(n_entries+1-playlist_index)d
Date/time Formatting: Date/time fields can be formatted according to strftime formatting by specifying it separated from the field name using a >. E.g. %(duration>%H-%M-%S)s, %(upload_date>%Y-%m-%d)s, %(epoch-3600>%H-%M-%S)s
Alternatives: Alternate fields can be specified separated with a ,. E.g. %(release_date>%Y,upload_date>%Y|Unknown)s
Replacement: A replacement value can be specified using a & separator. If the field is not empty, this replacement value will be used instead of the actual field content. This is done after alternate fields are considered; thus the replacement is used if any of the alternative fields is not empty.
Default: A literal default value can be specified for when the field is empty using a | separator. This overrides --output-na-placeholder. E.g. %(uploader|Unknown)s
More Conversions: In addition to the normal format types diouxXeEfFgGcrs, yt-dlp additionally supports converting to B = Bytes, j = json (flag # for pretty-printing, + for Unicode), h = HTML escaping, l = a comma separated list (flag # for \n newline-separated), q = a string quoted for the terminal (flag # to split a list into different arguments), D = add Decimal suffixes (e.g. 10M) (flag # to use 1024 as factor), and S = Sanitize as filename (flag # for restricted)
Unicode normalization: The format type U can be used for NFC Unicode normalization. The alternate form flag (#) changes the normalization to NFD and the conversion flag + can be used for NFKC/NFKD compatibility equivalence normalization. E.g. %(title)+.100U is NFKC

To summarize, the general syntax for a field is:

%(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type

Additionally, you can set different output templates for the various metadata files separately from the general output template by specifying the type of file followed by the template separated by a colon :. The different file types supported are subtitle, thumbnail, description, annotation (deprecated), infojson, link, pl_thumbnail, pl_description, pl_infojson, chapter, pl_video. E.g. -o "%(title)s.%(ext)s" -o "thumbnail:%(title)s\%(title)s.%(ext)s" will put the thumbnails in a folder with the same name as the video. If any of the templates is empty, that type of file will not be written. E.g. --write-thumbnail -o "thumbnail:" will write thumbnails only for playlists and not for video.

Note: Due to post-processing (i.e. merging etc.), the actual output filename might differ. Use --print after_move:filepath to get the name after all post-processing is complete.

Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. E.g. for -o %(title)s-%(id)s.%(ext)s and an mp4 video with title yt-dlp test video and id BaW_jenozKc, this will result in a yt-dlp test video-BaW_jenozKc.mp4 file created in the current directory.

Note that some of the sequences are not guaranteed to be present since they depend on the metadata obtained by a particular extractor. Such sequences will be replaced with placeholder value provided with --output-na-placeholder (NA by default).

Tip: Look at the -j output to identify which fields are available for the particular URL

For numeric sequences you can use numeric related formatting; e.g. %(view_count)05d will result in a string with view count padded with zeros up to 5 characters, like in 00042.

Output templates can also contain arbitrary hierarchical path, e.g. -o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s" which will result in downloading each video in a directory corresponding to this path template. Any missing directory will be automatically created for you.

To use percent literals in an output template use %%. To output to stdout use -o -.

The current default template is %(title)s [%(id)s].%(ext)s.

In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the --restrict-filenames flag to get a shorter title.
