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

Uncompressed Megabytes Per Second (MB/s)

Required number input.

Compression Ratio

Required number input.

Compressed decimal MB/s estimate from uncompressed data rate divided by an assumed compression ratio. 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]

Compressed Megabytes Per Second (MB/s)

The resulting compressed megabytes per second returned as a number.

• Storage and bitrate estimates depend on codec, chroma sampling, bit depth, frame rate, audio, metadata, overhead, variable bitrate, compression settings, and DCP profile. Nominal rates do not predict image quality or exact package size.
• 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.

• Data Rate Uncompressed

  Decimal megabytes per second for uncompressed constant-frame-rate raster video; excludes headers and audio.

• Chroma Subsampling Bandwidth

  Uncompressed decimal MB/s for YCbCr with one luma sample and two chroma channels at a supplied per-channel chroma sample fraction (0.25 for 4:2:0, 0.5 for 4:2:2).

• DCP Bitrate

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