@jsl76 Thanks. dupeGuru found a few more!
I had to set the "filter hardness" quite low, like to 20 (lots of false positives)... but it was fun.

@pawpcorn Thanks, and it also helps to remember the "active / including dead / only dead" pulldown next to the Search button.

My wishlist was growing and shrinking, "mysteriously" until I realized that some torrents go back and forth between active and dead, dependent on who is seeding at the time.

@b779a I haven't used Topaz but have seen results from others... and it does add sharpness, detail etc. the AI is able to guess what the existing (bad) video was downgraded from.

so the answers above from 2020 saying no it's impossible, are behind the times.
