Sony FX5 Data Calculator
The Sony FX5 is the first FX-series body with internal 16-bit X-OCN RAW — the VENICE and BURANO codec, now in a handheld Cinema Line camera. 5K Open Gate 3:2 up to 60p, three base ISOs, and a newly developed full-frame stacked sensor. This page covers the recording media math.
Sony FX5 X-OCN Data Rates
Verified data rates from Sony's launch specifications. X-OCN comes in three tiers on the FX5 — LT (the established VENICE/BURANO tier) plus new C1 and C2 tiers that compress harder for smaller files.
| Format | Resolution | Frame rate | Data rate |
|---|---|---|---|
| X-OCN LT | 5K Open Gate 3:2 (4992×3328) | 24p | 712 Mbps |
| X-OCN C1 | 5K Open Gate 3:2 (4992×3328) | 24p | 536 Mbps |
| X-OCN C2 | 5K Open Gate 3:2 (4992×3328) | 24p | 429 Mbps |
Sony FX5 Storage — Quick Examples
| Shoot | Data rate | Per minute | Per hour |
|---|---|---|---|
| 5K Open Gate X-OCN LT 24p | 712 Mbps | ~5.3 GB | ~320 GB |
| 5K Open Gate X-OCN C1 24p | 536 Mbps | ~4.0 GB | ~241 GB |
| 5K Open Gate X-OCN C2 24p | 429 Mbps | ~3.2 GB | ~193 GB |
A 1 TB CFexpress Type A card holds roughly 3 hours 7 minutes of 5K Open Gate X-OCN LT at 24p — or about 5 hours 10 minutes in C2. For RAW workflows this is remarkably storage-light: the R6 V's 7K Open Gate RAW consumes 1.17 TB per hour; the FX5's 5K X-OCN LT is under a third of that.
Recording Media for the Sony FX5
Dual slots accept CFexpress Type A or SD UHS-II. Internal X-OCN requires CFexpress Type A with VPG400 certification. SD UHS-II handles the XAVC compressed modes.
- Lexar Professional GOLD 1 TB CFexpress Type A — the only 1 TB Type A shipping. CFexpress 4.0, IP68. Three hours of X-OCN LT per card.
- Angelbird AV PRO CFexpress A v4 1 TB — CFexpress 4.0 with free lifetime data recovery. Pro-tier alternative at the same capacity.
- Sony Tough 640 GB CFexpress Type A — Sony's own VPG-certified card; the safe pairing for a Sony cine body. ~2 hours of X-OCN LT.
- ProGrade Digital Iridium 480 GB Type A — CFexpress 4.0, VPG-800 sustained writes.
Key Features for Storage Planning
Internal X-OCN RAW — first FX body with it. 16-bit sensor data at data rates a third of comparable RAW formats. The C1/C2 tiers make RAW affordable on storage: C2 at 5K 24p uses less space per hour than many 4K All-Intra XAVC modes.
5K Open Gate 3:2 — full sensor capture for reframing vertical and horizontal deliverables from one master file. Up to 60p; 5K 120p available in 16:9.
Three base ISOs (800 / 4000 / 12800) — a first for Sony. No storage impact, but it changes how much usable footage survives low-light shoots — plan capacity for more keepers.
Firmware 2.0 roadmap — 4K 240p X-OCN and Open Gate XAVC-I are announced for a future update. Data rates for those modes aren't published yet; we'll add them when Sony does.
Frequently Asked Questions
What recording media does the Sony FX5 use?
Dual CFexpress Type A / SD UHS-II slots. CFexpress Type A (VPG400) is required for internal X-OCN RAW. SD UHS-II covers XAVC modes.
How much storage does the FX5 need per hour of X-OCN?
At 5K Open Gate 24p: LT (712 Mbps) ≈ 320 GB/hr, C1 (536 Mbps) ≈ 241 GB/hr, C2 (429 Mbps) ≈ 193 GB/hr. A 1 TB CFexpress Type A holds ~3 hours of LT.
What is X-OCN and how is it different from XAVC?
X-OCN is Sony's 16-bit compressed RAW from the VENICE/BURANO line — maximum grading latitude at manageable data rates. The FX5 is the first FX body to record it internally. XAVC is Sony's conventional 10-bit codec family at lower rates; the FX5 records both.
Does the FX5 record Open Gate?
Yes — 5K 3:2 (4992×3328) up to 60p in X-OCN. 5K 120p in 16:9. 4K 240p X-OCN arrives via firmware 2.0.
