I’d actually be pretty interested to hear your results of using a median script on these various sources. I do think it runs the risk of basically selecting pixels from the same source all the time, due to slight color differences between the sources. That might be ok, if you rig it so the best source is likely to have the median pixel values, except in the case of encoding error, etc.

On another note, did you happen to see any other HDTV rips of Episode I? The Blu Rays of TPM and AOTC are so different as to make them unusable for this process, and you need three sources to do a median. I have the Premiere, SKY and Cinemax sources for AOTC, but only the first two for TPM.

Also, I know it’s somewhere else, but could you post your motion compensation script? I’d like to see how it works with these.
