Frequently Asked Questions
Why does 24fps film run faster on European 25fps television?
Historically, European PAL television broadcasts at 25 frames per second. The easiest way to broadcast 24fps cinema film without motion stutter was to speed it up by 4.1% (1 frame per second), resulting in slightly shorter runtimes and a +0.707 semitone pitch rise in audio.
