ProRes Data Rate Calculator
Apple's official target data rates for every ProRes flavor — Proxy through 4444 XQ — at 1080p, UHD 4K, and DCI 4K, with per-hour storage math. Values from the Apple ProRes White Paper. Rates scale linearly with frame rate.
ProRes Data Rates at 29.97 fps (Apple official)
| Flavor | 1920×1080 | UHD 3840×2160 | DCI 4096×2160 |
|---|---|---|---|
| ProRes Proxy | 45 Mbps | 145 Mbps | 155 Mbps |
| ProRes LT | 102 Mbps | 328 Mbps | 350 Mbps |
| ProRes 422 | 147 Mbps | 471 Mbps | 503 Mbps |
| ProRes 422 HQ | 220 Mbps | 707 Mbps | 754 Mbps |
| ProRes 4444 | 330 Mbps | 1,061 Mbps | 1,131 Mbps |
| ProRes 4444 XQ | 495 Mbps | 1,591 Mbps | 1,697 Mbps |
Frame-rate scaling: multiply by ~0.8 for 23.98/24p, ~0.83 for 25p, ~1.67 for 50p, ~2.0 for 59.94/60p. ProRes is constant-quality, so real files land close to these targets regardless of scene content.
Storage Per Hour — UHD 4K at 24p
| Flavor | Data rate (24p) | Per minute | Per hour |
|---|---|---|---|
| ProRes Proxy | 116 Mbps | ~0.9 GB | ~52 GB |
| ProRes LT | 262 Mbps | ~2.0 GB | ~118 GB |
| ProRes 422 | 377 Mbps | ~2.8 GB | ~170 GB |
| ProRes 422 HQ | 566 Mbps | ~4.2 GB | ~254 GB |
| ProRes 4444 | 849 Mbps | ~6.4 GB | ~382 GB |
| ProRes 4444 XQ | 1,273 Mbps | ~9.5 GB | ~573 GB |
Rule of thumb: a 1 TB drive holds about 4 hours of UHD ProRes 422 HQ at 24p, or roughly 1 hour 45 minutes of 4444 XQ.
ProRes RAW Data Rates
ProRes RAW is variable-bitrate and scene-dependent, so there's no single fixed number per resolution. Manufacturer-published examples give the practical range:
| Camera | Mode | Data rate | Per hour |
|---|---|---|---|
| Nikon Z9 / Z8 | ProRes RAW HQ 8.3K 24p | ~1,429 Mbps | ~643 GB |
| Nikon Z9 / Z8 | ProRes RAW HQ 8.3K 60p | ~2,965 Mbps | ~1.33 TB |
Expect actual ProRes RAW files to vary ±20% or more with scene complexity. For camera-specific numbers, use the calculator with your body selected — every value is sourced from the manufacturer's own documentation.
Cameras That Record ProRes Internally
Bodies in our calculator with internal ProRes recording: ARRI ALEXA 35 (4444 XQ / 4444 / 422 HQ), Sony VENICE & VENICE 2 (4K ProRes alongside X-OCN RAW), Nikon Z9 and Z8 (ProRes RAW HQ + 422 HQ), Blackmagic cinema bodies, and Apple iPhone Pro models (ProRes to external SSD). Pick your body in the calculator for its exact bitrate table.
Frequently Asked Questions
What is the data rate of ProRes 422 HQ at 4K?
707 Mbps at UHD 29.97 fps (Apple's target), 754 Mbps at DCI 4K. About 254 GB per hour at UHD 24p. Scale linearly with frame rate.
How much storage does ProRes need per hour?
UHD 24p: Proxy ~52 GB, LT ~118 GB, 422 ~170 GB, 422 HQ ~254 GB, 4444 ~382 GB, 4444 XQ ~573 GB per hour. Double those at 60p.
What is the data rate of ProRes RAW?
Variable and scene-dependent. Nikon publishes ~1,429 Mbps for Z9/Z8 ProRes RAW HQ at 8.3K 24p (~643 GB/hr) and ~2,965 Mbps at 60p. Lower resolutions scale down proportionally.
Is ProRes LT good enough for delivery?
For most online delivery and broadcast, yes — LT holds 10-bit 4:2:2 at roughly 70% of 422's rate, and its artifacts are rarely visible outside heavy grading. Use 422 HQ or better when the footage will be graded hard or keyed.
