DataLad "version" of the Андрій Попик YouTube channel serving a prototype/test-bed for establishing collection/update of videos from YouTube with subtitles etc.
You would need git-annex with or without DataLad and youtube-dl to be able to fetch video files.
Moreover you would need to run
git config annex.security.allowed-ip-addresses all
to allow git-annex to download using youtube-dl.
You would also need to set locally or globally
git config core.quotePath false
to see proper unicode filenames in output of git commands.
