turning good quality 64 hex 480 resolution videos into higher quality ones (see the charmane star screenshots I posted above). these were done through Topaz
The 2nd pic has been downscaled to 1080p, but I actually upscaled it to 288 hex 1620 using Topaz Video's newest Starlight Precise model.
hope I'm not violating any rules here, this is one screenshot from a Alexa Grace vid from InterracialPass that I had to downscale from 4k to 720p in Topaz
I've seen some old scenes upscaled with Topaz. It's the kind of stuff that works well when the source has already good definition.
With tools like Topaz Video AI/Photo Pro AI/Gigapixel, this is fairly easy now although for best results, some mucking around is required.
