I don’t see why it wouldn’t work. Everytime you press “S” on the HDV footage, you’re probably not on a GOP boundry. This would be the same difference. You’re picking a specific frame. It might have to work harder to get the info for that specific frame, but you’re not actually deleting the other footage so it can still determine what should be in that frame by going back to the original file.
