Ah, nice! I tried to avoid powershell while on windows, so don’t know much about it.
You can get all the IDs using yt-dlp
yt-dlp --flat-playlist --print id
Assuming you’re on linux, you can add at the end to save the list to a file. ids_all.txt
You can also add
--compat-options no-youtube-unavailable-videos
to get only the list of available videos instead and then, again assuming you’re on linux, do
diff ids_all.txt ids_available.txt
to get the odd ones out. That’s the simplest I could come up with. You’ll have to hope you can use the wayback machine, or a good old exact search to turn up what video that ID actually referred to
If you’re getting rid of a (rusty) drive and it leaves your hands with the cool magnets and shiny frisbees still inside, you’re doing something wrong.
I’m just here to lay some hate on the proprietary apps: they bad.
