Here’s how I would do it. Let’s say you have 5 videos, 1 for each wardrobe change. They were shot at 30fps. In Resolve I would sync these to the music on 5 video tracks. Then I would export TIFF image sequences 5 times to 5 separate folders, each time disabling all tracks but one. This will make 5 folders of each take with all the files named the same and the same sequential numbers. I would then create a dos batch or AutoIT script that copied every 5th frame, alternating between the 5 folders, into a new folder and renumbering them so they increment by 1. Import this new image sequence into Resolve, making sure Resolve interprets it as a video clip. In the clip attributes, set it to 6fps. Drag it to a 30fps timeline and it should now play at the original duration, in sync to the music track.
