You_Too,

I just thought about this option, but the "pyramid" set has no fixed aspect ratio, and it has few lines of resolution top and bottom, and less left and right... to match those two edition, first every scene has to be checked, then the "pyramid" should be cropped top and bottom (loosing few horizontal lines of resolution) and the THX laserdiscs captures should be cropped left and right (losing some vertical lines of resolution)... at this point, the picture is the smallest possible!

I tried some solutions on VirtualDub - as Spaced Ranger suggested - and found some setting are good, but still not perfect... I must find some time for more testing. If these (of more) settings could be right for the whole movie(s), then it can be possible to apply them only to pinkish scenes, and use the needed ones to replace the clipped-white/crusched-black ones.

It came also to my mind the idea of making a "pyramid" ruLes project... why not?
