Description

This is the output argument I am using:
-o "Downloads\Videos\%(extractor)s - %(uploader)s-%(upload_date)s-%(playlist)s #%(playlist_index)s - %(title)s [%(id)s].%(ext)s"

I would like for youtube-dl to, instead of always using this and then later requiring me to remove all the NA-NA-NA from files without the tags, know if the downloaded video actually has the tags and do a if check.

For example: https://v.redd.it/ps7wzmoq02j41 outputs Reddit - Artem10397-20200225-NA #NA - Russian cyberpunk. [ps7wzmoq02j41].mp4.
My feature proposal would make youtube-dl automatically rename it to Reddit - Artem10397-20200225- Russian cyberpunk. [ps7wzmoq02j41].mp4

That's technically impossible to implement what you request in your example. The max that can be is inserting empty strings instead of NA.

Are you saying that it's now possible to change to an empty string?
I agree with the @HASJ 's intention. It would be nice to change the NA statement with conditional or OR operation.
