Backing up a TikTok collection

I wanted to back up my TikTok collections in case they become unavailable in the future. Thankfully yt-dlp has pretty good TikTok support.

yt-dlp \
  -o "%(title).200B.%(ext)s" \
  --trim-filenames 80 \
  --restrict-filenames \
  --write-subs \
  --write-description \
  --write-link \
  --write-info-json \
  https://www.tiktok.com/@arnerk/collection/SF-7268525669053696810

Will back up all the videos in that collection (my list of SF-related videos) and create files for the subtitles, description, URL and a JSON file with all parsed metadata. The filenames are based on the video description so I force ASCII-only and truncate to 80 characters.
