## Screenshot Template

https://mpv.io/manual/stable/#screenshot

Specify the filename template used to save screenshots. The template specifies the filename without file extension, and can contain format specifiers, which will be substituted when taking a screenshot. By default, the template is `mpv-shot%n`, which results in filenames like `mpv-shot0012.png` for example.

The template can start with a relative or absolute path, in order to specify a directory location where screenshots should be saved.

If the final screenshot filename points to an already existing file, the file will not be overwritten. The screenshot will either not be saved, or if the template contains `%n`, saved using different, newly generated filename.

Allowed format specifiers:

`%[#][0X]n`
  A sequence number, padded with zeros to length X (default: 04). E.g. passing the format `%04n` will yield `0012` on the 12th screenshot. The number is incremented every time a screenshot is taken or if the file already exists. The length `X` must be in the range 0-9. With the optional # sign, mpv will use the lowest available number. For example, if you take three screenshots--0001, 0002, 0003--and delete the first two, the next two screenshots will not be 0004 and 0005, but 0001 and 0002 again.
`%f`
  Filename of the currently played video.
`%F`
  Same as `%f`, but strip the file extension, including the dot.
`%x`
  Directory path of the currently played video. If the video is not on the filesystem (but e.g. `http://`), this expand to an empty string.
`%X{fallback}`
  Same as `%x`, but if the video file is not on the filesystem, return the fallback string inside the `{...}`.
`%p`
  Current playback time, in the same format as used in the OSD. The result is a string of the form "HH:MM:SS". For example, if the video is at the time position 5 minutes and 34 seconds, `%p` will be replaced with "00:05:34".
`%P`

  Similar to `%p`, but extended with the playback time in milliseconds. It is formatted as "HH:MM:SS.mmm", with "mmm" being the millisecond part of the playback time.

  Note

  This is a simple way for getting unique per-frame timestamps. (Frame numbers would be more intuitive, but are not easily implementable because container formats usually use time stamps for identifying frames.)

`%wX`

  Specify the current playback time using the format string `X`. `%p` is like `%wH:%wM:%wS`, and `%P` is like `%wH:%wM:%wS.%wT`.

  Valid format specifiers:
    `%wH`
      hour (padded with 0 to two digits)
    `%wh`
      hour (not padded)
    `%wM`
      minutes (00-59)
    `%wm`
      total minutes (includes hours, unlike `%wM`)
    `%wS`
      seconds (00-59)
    `%ws`
      total seconds (includes hours and minutes)
    `%wf`
      like `%ws`, but as float
    `%wT`
      milliseconds (000-999)
`%tX`
  Specify the current local date/time using the format `X`. This format specifier uses the UNIX `strftime()` function internally, and inserts the result of passing "%X" to `strftime`. For example, `%tm` will insert the number of the current month as number. You have to use multiple `%tX` specifiers to build a full date/time string.
`%{prop[:fallback text]}`
  Insert the value of the input property 'prop'. E.g. `%{filename}` is the same as `%f`. If the property does not exist or is not available, an error text is inserted, unless a fallback is specified.
`%%`
  Replaced with the `%` character itself.
