Any Alternatives For Finding Deleted/Private Videos

I have recently been going through my older playlists trying to recover some videos from channels I followed when I was younger that have had either their channels or large amounts of their videos nuked, Violette1st and ImJayStation in particular. I have been trying to use the Internet Archive’s Wayback Machine with the urls I can find, but their defective website only manages to save about 1/20 videos despite the site claiming to have “archived” the url. I was wondering if anyone else has had similar experiences and if you have found a site that is better at archiving Youtube videos?
