How are time measurements made?
Either by directly timing the events of the films on videotape or DVD using a stopwatch or inbuilt clock; by noticing timing information within the film (eg. the Death Star countdown announcements in A New Hope); or by counting the number of frames between events. Frame rates, according to the advice of W.Poe, include: • NTSC video: 30/s • PAL video: 25/s • American film: 24/s • European film: 25/s • Super 8 film (home): 18/s • Super 8 film (?): 24/s When American films are converted to PAL video, the usual procedure is for each frame of film to become a frame of video, and the total screening time is shortened slightly. When American films are converted to NTSC video, every fifth frame of film is repeated on video, so that five frames become six frames.
