Estimated running time with lengths of 30.5m (100ft) and 122m (400ft) of footage at the typical frame rates:
30.5m (100ft) R-90 daylight spool
24 frames per second = 2min 49s
25 frames per second = 2min 42s
122m (400ft) roll with a core
24 frames per second = 11min 6s
25 frames per second = 10min 40s
NOTE: The film is developed as a negative so it is not directly viewable on a projector because its colors are inverted (hence the negative).
After development the negative film can be scanned into a digital format in which the colors are turned to normal.
