I was going to show the results of this Avisynth script to align the 2 scans. On double-checking before posting, I noticed the video of one film was shifted by 1 frame even though none of the settings had changed (and were printed onto the picture). Going back and running it again, they then were properly aligned, with the same settings . .

Clearly something in Avisynth (this system is running v.2.5.8) is wrong and cannot be relied upon to serve up the correct images. Sorry this approach turned out to be useless.

(Normally I’d put a cool, animated smiley here, but my smiley resource site "http://www.freesmileys.org/" completely disappeared a several days ago …

… and a lesson for us all -[as spoken by Tony "Felix Unger" Randall].) 😉
