Use this cinematography or projection calculation to plan image geometry, exposure, timing, storage, film footage, or presentation from explicitly stated camera and display parameters.

Frames Per Foot (frames/ft)

Required number input.

Frames Per Second (fps)

Required number input.

Runtime of a nominal 2,000-foot reel from gauge-dependent frames per foot and projection frame rate. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Runtime Minutes (min)

The resulting runtime minutes returned as a number.

• Film footage and runtime conversions depend on gauge, perforation format, frames per foot, frame rate, leader, tails, splices, reel capacity, and scanning convention. Actual usable footage and archive condition require inspection.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Confirm critical values with the actual camera, lens, codec, projector, and delivery specification, then run a camera or projection test under representative conditions.

• Footage To Runtime

  Film runtime from footage, gauge-specific frames per foot and projection frame rate.

• Runtime To Footage

  Film footage needed for a runtime at a specified frame rate and gauge-dependent frames-per-foot value.

• Reel Length 2000 ft

  Metric length of film loaded onto a nominal 2,000-foot reel at the supplied fill fraction; full reel is 609.6 m.
