Don't upscale frames that don't change from a previous frame. It's useful for upscaling anime where video has a lot of repeating frames

Expected Behavior

Doesn't reupscale repeating frames

Current Behavior

upscales all frames

Mark this as help wanted because this requires some kind of on-going visual analytic algorithm.

What's the problem aside from taking a long time?

Sveagruva commented 1 hour ago

No problems aside from redundant work being done. I don't think it requires complicated algorithm. When upscaling a frame check if it matches previous one (pixel by pixel) and if it does just copy previously upscaled frame instead of upscaling it.

Yeah.. that needs the image recognition algorithm to analyze pixel differences. I'll see what I can do. Mark this as optimization feature.
