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

Feature Minutes (min)

Required number input.

Trailer Minutes (min)

Required number input.

Intermission Minutes (min)

Required number input.

Program runtime from feature, trailer and intermission durations, all in minutes. 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]

Program Minutes (min)

The resulting program minutes returned as a number.

• Real results depend on lens design, sensor or film dimensions, focus criteria, transmission, exposure calibration, codec settings, color pipeline, projector setup, screen, viewing environment, and manufacturer conventions. Nominal specifications and simplified formulas may not match measured performance.
• 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.

• Trailer Runtime Total

  Total trailer runtime estimated from trailer count and mean trailer duration; excludes feature and intermission.

• Intermission Time

  Intermission duration from the program-minute offset at pause and at resumption.

• Bitrate From File Size Runtime

  Average decimal megabits per second from a decimal megabyte file size and duration; includes any audio/container overhead already in the size.
