Oh, one more thing AntcuFaalb, the script in the first post has the option to determine the correction from two different sources, and then apply it to a third. So you MAY get a bit more accurate results if you crop the GOUT and the rental copy to match each other first, and then apply the changes to the uncropped GOUT. The version that You_Too posted doesn't have this option, so I'll make an updated version after Christmas that has all the options of both scripts, and maybe a YUV version as well. I don't have my computer with me right now, otherwise I'd get on it sooner.
