129,600 frames
Work Step by Step
To produce a ninety-minute animated production for a motion picture theater, typically 24 frames per second (fps) are used. To calculate the total number of frames needed, multiply the number of minutes by the number of seconds per minute and then by the frames per second:
90 minutes * 60 seconds/minute * 24 frames/second = 129,600 frames.
So, 129,600 frames would be required to produce a ninety-minute animated production for a motion picture theater.
