Hi Nils, I just stumbled over this thread, as I also need to change the field dominance of literally thousands of clips in an hour-long timeline. We’re trying to up-res an old SD show that was unfortunately mastered in letterbox format even though it was shot in DV 480p 16:9 anamorphic… this effectively reduced the usable vertical resolution from 480p to 360p. 🙁
Our plan is to nest and scale the original 4:3 letterbox sequence into an 854x480p or 1280x720p ProRes timeline in order to avoid re-composing all the content. This works great for everything (keyframed stills, text, graphics, etc), but the main video clips look terrible unless their field dominance is set to “none” (the material was shot in a progressive 30p format on a Sony DSR450WS… great camera/format even by today’s standards, btw).
Do you have more information on this “bug” trick you found to change item properties for multiple clips in a timeline? I cant figure out how to get this to work… any help would be *very* appreciated!
thanks,
Robert.
