Thanks for the suggestion. I tried it without success. Maybe because I’m on Mac? I’m on OS 10.6.8. Are you on Mac?
I imported a simple QuickTime video of 12 frames running at 12fps. While I can see that Photoshop has created 12 layers and they are all correct, Photoshop also created a Timeline of 30 fps. I’m not sure why it didn’t recognize that the film clip is 12fps.
So I changed the Timeline from 30fps to 12fps and rendered the video as an image sequence at 12fps. What a mess! – it spit out 23 frames: 1 frame of each of frames 01 to 04, missing frame 05, one of frames 06 to 09, missing frame 10, one of frame 11, and 15 copies of frame 12!
