filter videos with(out) given subtitle

Hi,

Is there any way to filter a video section or tv show based on the presence or not of a given (language) substitle?
Thanks.

There is not, unfortunately.

If you want this as a list of movies to try and fetch subtitles, the best you can do is to use
Plex2CSV to export your library into a text file.
Then use a spreadsheet application to sort and filter for the ‘Subtitle Language’ column.
