Occasionally my personal/literature/academic/tech notes link to a youtube source, but when clicking on it I find the video has vanished with no way of knowing what it was or even what it was called (it's sometimes impossible to track down an identical/replacement source). I lost many valuable references that way.
Wayback machine solves for webpages, but nothing I'm aware of (short of youtube-dl-ing the video yourself and storing it somewhere openly, probably at risk of various infringements) solves this. Quite a lot of hassle for something rather simple.
It would be great to be able to immortalise them on a per-video basis, so if it's important enough, we can be sure that references made to the content will still be there in the future when needed.
I do not see how that becomes possible without the Internet archive effectively mirroring a large percentage of YouTube. I recall at one point, IA wanted to archive just the video metadata and realized even that would be technically challenging.
Only if a user chooses to submit the URL - I think parent comment is referring to an organized attempt by IA to archive a significant portion of YT's videos.
It would be nice to prioritize videos which are deemed at "high risk" of being deleted, with bayes statistics or machine learning or something like that.
Any video you care about, you need to make it your own responsibility to backup the metadata and/or streams. If you're lucky you can internet search the video ID to get the metadata, even after deletion.
