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

Traveled Pixels (px)

Required integer input.

Duration Seconds (s)

Required number input.

Average vertical credits scroll speed from total traveled pixels and scroll duration. 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]

Pixels Per Second (px/s)

The resulting pixels per second 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.

• 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.

• DCP Bitrate

  Average total DCP bitrate in decimal Mb/s from decimal gigabytes and running seconds.

• Frame Rate To Shutter Speed

  180-degree shutter convention: exposure duration is half a frame period, 1/(2·fps).
