Tguyus, I appreciate both your first post and that you came back and adressed legitimate objections with concise positive knowlege. My mind DID gravitate to your solution, because I did it once on a small scale. I had a folder of 300 frames, .tif, and I wanted to test an idea for "guerilla post-processing." So, I opened one frame in my graphics software and establsihed the change I wanted. It amounted to a desaturation of about 50 frames in one place, and the overlay of a layer starting in a certain place and going to the end. In both cases the exact same edit was needed on each subsequent frame. I was able to create a macro. I set it loose on the folder. It took a LOT of fiddling, but I DID get it to work. My software is Canvas. (Yes, I know, no one in this forum has ever heard of it and howcome operaguy does not have Photoshop. Insert smiley face here.) Now...is there a substantive difference in manipulating the frame with a great 2D editor and running a macro (if the change is consistent, such as a re-size or crop) then there would be with top-flight video editing software? You never know. There COULD BE. Perhaps even the best video editing software would fall short in some respect (2D graphics pros -- I am not one -- can do insane magic - and it may be memorizeable)...and there might be a window of opportunity to take a copy of the master folder and unleash the most godawful macroization ever attemptd on it. Might need one of those dual opteron screamers jacqui mentioned above! I appreciate you placing two posts here on this issue, especially the important information that you DID achieve superior results in Photoshop than in a few mediumly fine editing apps. I will definitely give this out-of-the-box idea due respect. Thanks. ::::: Opera :::::
