I'm shooting 3-perf 35mm @ 24 fps. How many feet of film do I need if I'm shooting one hour?

Is there a good site/app for calculating this?

4,050 feet of film.

Kodak makes a free app for iOS called "KODAK Cinema Tools" which has a film calculator, among other features.

http://motion.kodak.com/US/en/motion/Tools/Mobile/index.htm

For reference:

  • 8mm = 80.0 frames per foot
  • Super 8 = 72.0 frames per foot
  • 16mm = 40.0 frames per foot
  • 35mm 2-perf = 32.0 frames per foot
  • 35mm 3-perf = 21.3 frames per foot
  • 35mm = 16.0 frames per foot
  • 65mm = 12.8 frames per foot
