You can't save a configuration file from QuickTime Player Pro. (How hard would that have been?)
You need to open video file, set up the export settings, then run an AppleScript like this one:
tell application "QuickTime Player"You'll need to edit the "BootDrive ..." stuff to match your hard drive (Volume) name and user name.
tell first document
save export settings for QuickTime movie to file "BootDrive:Users:jfaughnan:Documents:aic2.set"
What a nuisance!
