I'm trying to fix some old 640x480 Inuyasha footage which has some rainbowing issues. My ultimate goal is to get a decent upscale up to 1280 so that I can then crop it down to my 720 video. I tried to get mfrainbow running but it throws an error saying it doesn't know what UnsharpMask is, even though I have warpsharp included. I then settled for Bifrost but for the life of me, I can't seem to get it to actually do anything. The result I get out still has the horrendous rainbowing on the coat.
Does anyone have any suggestions on how to tackle this? Is the footage a lost cause? Below in the spoiler is a screenshot of what I'm dealing with. Any advice would be appreciated.
