What does Uc mean in Cinema?

In the context of cinema, "Uc" typically stands for "Under Cranking". It refers to the technique of filming at slower than the standard frame rate, which is traditionally 24 frames per second (fps). By undercranking, filmmakers can create a slow-motion effect in post-production. The opposite of undercranking is "Over Cranking", which involves filming at a higher frame rate to achieve fast-motion effects.
