Excellent! The smearing definitely is reduced, and I agree the color change is slight enough to get away with. I have no technical know-how in writing programs or scripts, so this is very much appreciated.

One note though, I’ve noticed most of the shots have different luminance from the screener, which is affecting the saturation of the colors. Look at the chap on the right’s face and the back wall, both are too dark and saturated in the merged version compared to the screener. Would there be any way to adjust this with the program given the crushed values of the Blu-Ray?
