I discovered a weird issue with Video Enhance AI, and it is definitely not my computer:
I have a source .ts file at 720p and I wanted to upscale it. If I use Proteus, Artemis, conversion is at about 0.28 s/frame when scaling to 1080p.
However, when choosing 4k, it takes 6.9s/frame, which is comparatively a huge difference.
Long story short, as soon as the upscaling reaches 240%, processing slows to a crawl at 6.9s/frame. But if I choose 239.99%, it processes at 0.28s/frame!
The models affected are at least Artemis and Proteus. I assume this must be a bug somewhere.
