Estimated running time of a single 15 m (50 ft) film cartridge at the most typical frame rates:
18 frames per second = 3min 20s
24 frames per second = 2min 30s
25 frames per second = 2min 24s
(Calculated running times, may vary by camera model)

NOTE: The developed TRI-X film can be viewed on a projector as the gray tones of the film are turned from negative to positive in the development process (hence the reversal film).
After development TRI-X can be scanned into a digital format.
