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

Horizontal Pixels Per Second (px/s)

Required integer input.

Readout Milliseconds (ms)

Required number input.

Horizontal rolling-shutter displacement of an object moving at constant image speed during full sensor readout. 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]

Skew Pixels (px)

The resulting skew pixels returned as a number.

• Shutter-angle, frame-rate, blur, flicker, and rolling-shutter estimates assume defined exposure timing and scan direction. Sensor readout mode, light modulation, synchronization, motion path, and dropped or duplicated frames affect the observed artifact.
• 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.

• Motion Blur Shutter Angle

  Shutter angle needed for a target moving-object blur length, from image speed in pixels per second and frame rate.

• Rolling Shutter Readout Time

  Total row-by-row sensor readout time from active row count and time per line.

• 35mm Equivalent Focal Length

  35 mm full-frame-equivalent focal length using the 36×24 mm diagonal divided by the camera sensor diagonal.
