Filming & Production
Slow motion
Also called: slow-mo, overcranking
Shoot at 120 frames per second, play at 24, and one second of real time becomes five seconds on screen with every frame genuine. The old film term is overcranking, from hand-cranked cameras run faster than standard. Slowing a normal clip down in the edit is a different thing entirely, since the software invents the missing frames and the result stutters or smears.
High frame rates need light, because each frame gets a shorter exposure, so plan a brighter setup than usual. Sound recorded at high speed is unusable once stretched, so capture audio separately.
