We could add a few validators for audio & video files. We would need something to analyse such files and ... tada! There is already one built-in Rails around FFMPEG:

• video: https://api.rubyonrails.org/v7.1.3.4/classes/ActiveStorage/Analyzer/VideoAnalyzer.html

We would then just have to build the validations on top on the retrieved metadata, that wouldn't be such a big issue I guess :) A bit of work yes but nothing too hard.

@igorkasyanchuk & @gr8bit what do you think?
