Thanks Baedi1966, but are you sure about that? TMPGEnc Autoring Works 7 says it's 20 fps, and that's why the sound from the projector at 18fps is also lagging......
Hello, it is scanned frame by frame and then the film is played back at 18 frames per second... which is standard for cine film! There were also cameras where 24 frames per second were possible, but that was rather the exception! But as a rule you will want to post-process the film with a video editor anyway, where you can also change the speed if you don't like the result!
