Shooting ratio
From Wikipedia, the free encyclopedia
The shooting ratio of a film or video is the ratio between the total duration of its footage shot and that which results from its final "cut".
A film with a shooting ratio of 2:1 would have shot twice the amount of footage that was used in the film. In real terms this means that 120 minutes of footage would have been shot to produce a film of 60 minutes in length.
Shooting ratios can vary greatly between productions but a typical shooting ratio for a production using film stock will be between 6:1 and 10:1, whereas a similar production using video is likely to be much higher. This is a direct result of the significant difference in price between video tape stock and film stock and the necessary processing.
