How much storage on the card
We compute the size of a shoot from codec, resolution and frame rate — for one camera and for the whole rig.
Size is computed from the target bitrates for mezzanine files: in-camera compression (H.264, HEVC) takes less space than ProRes.

How we calculate
Data tier:Aprimary sourceVerified: 03 Nov 2026Formula
bitrate = codec coefficient (Mbit/s per 1 Mpx/s) × (width × height × fps ÷ 1,000,000); size = bitrate × 1,000,000 × (hours × 3600) ÷ 8
Data sources
- Apple ProRes white paper: target bitrate ~147 Mbit/s at 1920×1080 @29.97 fps
- Apple ProRes white paper, target bitrate, 1920×1080 @29.97 fps — verified 03.11.2026
The value is confirmed by a primary source — the vendor document.
Caveat
Plan card space using the Apple target bitrates: our measurement on a synthetic source is lower, because a test pattern contains almost no detail.
