youtube-dl is a way of getting videos off of youtube and some other sites. I've successfully used it on soundcloud to download Trillbillies and And Introducing episodes that weren't normally downloadable, but I haven't tried it elsewhere.
You run it through command lines instead of browser add-ons like other downloaders I've used in the past, which makes it seem intimidating at first if you aren't accustomed to it. Once you get the basic functions, it's pretty good though. You can even download whole youtube playlists in one command.
Here's a "cheat sheet" a person wrote for using it: https://sachithmuhandiram.medium.com/youtube-dl-cheatsheet-bcc0782e7124
indispensable tool. also worth getting it directly from the site since the GitHub repo was briefly taken down by an absurd DMCA claim by the RIAA (and also GitHub is generally Microshit)
One thing the cheatsheet doesn't mention is you can specify both the audio and video format at the same time and youtube-dl will combine them.
In the example given in the post, the best format that has both video and audio included is
22 mp4 1280x720 hd720 221k , avc1.64001F, mp4a.40.2@192k (44100Hz) (best)
but there are better formats available in video only and audio only:
248 webm 1920x1080 1080p 1445k , vp9, 30fps, video only, 48.80MiB
251 webm audio only DASH audio 144k , opus @160k, 15.32MiB
so to get those as a single file you would doyoutube-dl -f 248+251 video-url
You don't even have to dig into the available qualities, you can just do
youtube-dl -f bestvideo+bestaudio video-url
and it will automatically pick the best format for each and combine them into one file.Thank you i never quite understood how that work, but the cheat sheet got me to download and install super easy!
