Compressing flics

I was wondering, is there any way to "quantize" a flic? You know, compare each pixel in frame B with the coresponding pixel in frame A. If the color-difference is within a certain threshold, make the pixel in frame B a non-delta pixel–reducing the number deltas where the colors from one frame to the next are very close (or not so close). Depending on the threshold you could control quality verses size. It would greatly reduce the size of 3D rendered flics that have "crawlys" and flics produced from video sources. Is there a POCO that will do it, or some other way? -Jeff B.

There's no POCO routine at present that does that. Sounds like an interesting task for someone… – Jack

Yah, would be nice if it were an INK so you could apply it to selected areas only. You can sort-of do it full-frame by importing the flic into Video for Windows doing RLE or Video-1 compression on it. But that's painfully inconvenient and slow, esspecially to convert it back to FLC. I have a 500 frame 640×480 FLC. If I start it now, it'll be done by Christmas. -Jeff B.
