Data rates: ProRes/DNxHR are per-frame constants from the Apple/Avid specs; RAW derives from resolution × bytes/pixel (nominal). Details further down this page.
ProRes RAW HQ: GB per hour
ProRes RAW HQ is a RAW format: data volume follows from resolution × 0.79 bytes per pixel per frame (nominal, derived from the manufacturer spec) × frame rate. Content-adaptive compression can land slightly below — you budget the nominal value, because the card has to survive the busiest take.
| Resolution | 24p | 25p | 30p | 50p | 60p |
|---|---|---|---|---|---|
| HD 1920×1080 | 138 | 144 | 173 | 288 | 346 |
| UHD 3840×2160 | 553 | 576 | 691 | 1,152 | 1,382 |
| 4K DCI 4096×2160 | 590 | 614 | 737 | 1,229 | 1,474 |
| 6K 6144×3240 | 1,327 | 1,382 | 1,659 | 2,764 | 3,317 |
| 8K 8192×4320 | 2,359 | 2,457 | 2,949 | 4,914 | 5,897 |
From GB to a shoot day
A typical shoot day produces 2–4 hours of footage per camera. At ProRes RAW HQ in UHD 25p that is 1,152–2,304 GB per camera — before copies. With 3-2-1 backup (three copies) it multiplies to 5.1 TB per three hours of material. The table runs three full shoot-day scenarios:
| Footage | Raw data | 1 TB cards | 3-2-1 volume | Offload per copy (400 MB/s) |
|---|---|---|---|---|
| 2 h | 1.12 TB | 2 | 3.37 TB | 49 min |
| 4 h | 2.25 TB | 3 | 6.75 TB | 1 h 38 min |
| 8 h | 4.50 TB | 5 | 13.50 TB | 3 h 17 min |
Planning offload and backup
Offload is the underrated line: securing a 1 TB card over a 400 MB/s link takes about 42 minutes per copy. Book the DIT only for wrap and you have booked a night shift.
In the schedule this number belongs in two places: as a card budget on the equipment list and as an offload window in the day plan. TillyGen keeps both in the same plan — change the shooting hours and the offload window moves with them.
Frequently asked
How much storage does 1 hour of ProRes RAW HQ need?
In UHD at 25p: 576 GB. At 50p, double that. Every resolution is in the table above.
Are the numbers exact?
RAW rates are manufacturer nominal values; content-adaptive compression can land slightly below. For capacity planning, use the nominal value plus 10 % headroom.
