Pulldown

Cinema is shot at 24 frames per second, but North American video is 30 fps. To make 24 fps fit, every other frame is duplicated in a 2:3:2:3 pattern, called 3:2 pulldown. This matters when you shoot motion picture film and intend to transfer to video: the pulldown can affect motion smoothness. The app's cine module accounts for this when calculating effective shutter angles.
