The Sony FX6 records UHD 4K at up to 600 Mbps in XAVC-I (All-Intra) at 60p, 50p, and 30p. DCI 4K (4096×2160) tops out at 240 Mbps at 24p. HD All-Intra runs 222 Mbps at 120p. Source: Sony PXW-FX6 Help Guide.
At UHD 4K 60p XAVC-I (600 Mbps), a 512 GB CFexpress Type A card holds approximately 113 minutes (1 hour 53 minutes) of footage. At UHD 4K 24p XAVC-I (240 Mbps), the same card holds about 4 hours 43 minutes.
The Nikon Z9 and Z8 share the same recording pipeline. N-RAW 12-bit High Quality at 8.3K (8256×4644) hits 5780 Mbps at 60p, 3470 Mbps at 30p, and 2780 Mbps at 24p. ProRes RAW HQ at 8.3K runs 2965 Mbps at 60p. Both bodies require CFexpress Type B media.
The Nikon Zr records 6K (6048×3402) N-RAW 12-bit High Quality at 3730 Mbps at 60p, which is roughly 27.9 GB per minute, or 1.68 TB per hour. At 24p the same setting runs 1490 Mbps, about 671 GB per hour. The Zr writes to CFexpress Type B in slot 1 and microSD UHS-I in slot 2; high-bitrate N-RAW capture requires the CFexpress slot.
The Canon EOS R5 Mark II records 8K (8192×4320) Cinema RAW Light at 2600 Mbps from 24p through 60p in Standard quality, or 1340 Mbps at 24p in Light quality. It requires a CFexpress Type B card. Source: Canon EOS R5 Mark II Advanced User Guide.
The Panasonic Lumix GH7 records ProRes RAW HQ at its native 5.7K (5728×3024) at up to 2470 Mbps at 30p. Internal ProRes 422 HQ at C4K 60p runs 1885 Mbps. The GH7 uses dual SD UHS-II slots and supports USB-C SSD recording for ProRes RAW.
Yes for video. The FX3 and a7S III share the same sensor and identical bitrate tables: XAVC S-I 4K at 600 Mbps (60p, 50p), XAVC HS 4K at 280 Mbps (120p), XAVC S 4K at 200 Mbps (60p). The FX3 adds DCI 4K (4096×2160) output that the a7S III does not record.
The Sony BURANO records X-OCN LT (16-bit compressed RAW) at up to 2169 Mbps at DCI 8K (8192×4320) 30p, and 2327 Mbps at UHD 8K (7680×4320) 30p. XAVC H-I HQ 8K runs 1231 Mbps at 30p, XAVC H-I SQ 8K runs 826 Mbps. The Burano is Sony's only body that records X-OCN LT but not the higher-tier ST or XT variants (those require VENICE 2). Records to dual CFexpress Type B VPG400 slots.
At ARRIRAW LF 16:9 UHD 24p (2393 Mbps), the ARRI ALEXA Mini LF consumes about 17.9 GB per minute, or 1.08 TB per hour. At ProRes 4444 XQ LF UHD 24p (1608 Mbps), per-hour usage drops to 723 GB. At ProRes 422 HQ LF UHD 24p (706 Mbps), an hour is approximately 318 GB. The camera records to Codex Compact Drive (1 TB or 2 TB) or legacy CFast 2.0 media.
The ARRI ALEXA Mini (Super 35, 2015) records ARRIRAW Open Gate (3424×2202) at 2262 Mbps at 25p, ARRIRAW 4:3 (2880×2160) at 2262 Mbps, and ProRes 4444 XQ 16:9 UHD at 1858 Mbps at 25p. ProRes 422 HQ UHD runs 826 Mbps. Records to CFast 2.0 media. It remains one of the most-shot indie-feature cinema bodies — used market is heavy.
The Sony a7S III records XAVC S-I 4K (3840×2160) at up to 600 Mbps at 60p (300 Mbps at 30p), XAVC HS 4K at 280 Mbps at 120p, and XAVC S 4K at 200 Mbps at 60p. Records to dual CFexpress Type A / SD UHS-II slots. The FX3 shares the same sensor and identical bitrate tables but adds DCI 4K (4096×2160) output that the a7S III does not record.
The Sony a1 II (2024) records 8K UHD (7680×4320) in XAVC HS at 520 Mbps from 24p through 30p. 4K (3840×2160) XAVC HS tops out at 200 Mbps at 60p, and XAVC S-I 4K runs up to 600 Mbps at 60p. The a1 II requires dual CFexpress Type A slots for sustained 8K capture; SD UHS-II works for lower-tier XAVC modes.
The Blackmagic Pocket Cinema Camera 6K G2 records Blackmagic RAW 3:1 at 6K (6144×3456) at 1880 Mbps at 24p (up to 3917 Mbps at 50p), and BRAW 5:1 at the same resolution at 1128 Mbps at 24p. At 4K (4096×2160), BRAW 3:1 runs 960 Mbps at 24p (2400 Mbps at 60p). The camera records to CFast 2.0, SD UHS-II, or USB-C SSD media.
The ARRI ALEXA 35 records ARRIRAW (13-bit) and Apple ProRes 4444 XQ / 4444 / 422 HQ. At 25 fps (ARRI's published baseline), ARRIRAW 4.6K 3:2 Open Gate (4608×3164) runs 4644 Mbps, ARRIRAW 4K 16:9 (4096×2304) runs 6625 Mbps, and ProRes 422 HQ UHD runs 733 Mbps. Bitrates scale linearly with frame rate — ARRIRAW 4K 16:9 at 60p hits 15,900 Mbps and at 120p reaches 31,800 Mbps. The camera records to CODEX Compact Drive 1 TB or 2 TB (rental/cinema media).
At ARRIRAW 4.6K 3:2 Open Gate 24p (4458 Mbps), the ALEXA 35 consumes about 33.4 GB per minute, or 2.01 TB per hour — meaning a 2 TB CODEX Compact Drive holds roughly 60 minutes. At ProRes 4444 XQ 4K 16:9 24p (1777 Mbps), per-hour usage drops to 800 GB. At ProRes 422 HQ UHD 24p (704 Mbps), an hour is approximately 317 GB. Use the calculator above to compute any combination of resolution, codec, and frame rate.
The RED KOMODO-X (2023) records 6K S35 (6144×3240) R3D NE 12-bit at up to 4780 Mbps at 60p in HQ quality, 3360 Mbps in MQ, and 2100 Mbps in LQ. 6K 24p HQ is 1912 Mbps. The camera supports 6K up to 80fps and 4K up to 120fps, and writes to CFexpress Type B. The original RED KOMODO 6K (2020) caps at 40fps in 6K (3187 Mbps HQ) and uses CFast 2.0 media instead of CFexpress.
At 8K VV (8192×4320) R3D NE 12-bit HQ at 24p (3400 Mbps), the RED V-RAPTOR consumes about 25.5 GB per minute, or 1.53 TB per hour. At 8K 60p HQ (8500 Mbps) that climbs to roughly 3.83 TB per hour. The V-RAPTOR records to CFexpress Type B; sustained 8K capture at higher frame rates typically requires the fastest available CFexpress 4.0 cards.
Every bitrate on this site is pulled directly from manufacturer documentation: Nikon online manual tables, Sony per-body Help Guide PDFs, Canon Advanced User Guides and published specifications, Apple ProRes specifications, and the official spec sheets for Blackmagic, Panasonic, Fujifilm, RED, DJI, GoPro, Insta360, OM System, Sigma, Z CAM, and Leica. No scraped forum posts, no estimates. Manufacturers report average bitrates for variable-rate codecs; high-motion shots can exceed the published average, so plan with the 5%, 10%, or 20% buffer toggle.
A video storage planner for filmmakers and content shooters. You pick the camera, codec, and runtime. It tells you the total video file size and exactly how many memory cards you need. No signup. No tracking. The math is all I care about.

Install Camera Data Calculator as an app from your browser. On desktop, tap "Install" in the address bar. On iOS or Android, use "Add to Home Screen." Once it's installed, the whole camera database lives on your phone. No internet needed on set. Your shoot data never leaves the device.
Manufacturers report average bitrates for variable-rate codecs. Real shoots fluctuate. High-motion or detailed scenes can run higher than the published average. Treat results as planning guidance and always pad your card count. The buffer toggle gives you 5/10/20% padding for that.
I built this because I got tired of doing card math from spec sheets the night before a shoot, and because the existing tools assume you already know the bitrate of every codec you might pick. I'd rather just pick the camera and have the math handed to me. Spotted a bug, see a missing camera, or have data that disagrees with mine? Email hello@cameradatacalculator.com and I'll fix it.
