Sony data rates per hour

The headline numbers — how much data each Sony cinema camera writes per hour of recording at 25 fps. Use the calculator above for other frame rates, codecs and record times.

FX6 / FX3

FX6 & FX3 · 25 fps
Codec & format	Data rate	Per hour
XAVC S-I (All-Intra) · 4K UHD	~250 Mbps	~113 GB
XAVC HS (Long GOP HEVC) · 4K UHD	~200 Mbps	~90 GB
XAVC S (Long GOP H.264) · 4K UHD	~100 Mbps	~45 GB
XAVC S-I · 1080p	~93 Mbps	~42 GB
XAVC S · 1080p	~50 Mbps	~23 GB

FX30 / FX9

FX30 & FX9 · 25 fps
Codec & format	Data rate	Per hour
FX30 · XAVC S-I · 4K UHD	~250 Mbps	~113 GB
FX9 · XAVC Intra (Class 300) · 4K UHD	~250 Mbps	~113 GB
FX9 · XAVC Long GOP · 4K UHD	~100 Mbps	~45 GB

BURANO

BURANO · 25 fps
Codec & format	Data rate	Per hour
X-OCN LT · 8.6K 17:9	~1,779 Mbps	~800 GB
X-OCN LT · 6K 17:9	~542 Mbps	~244 GB
XAVC H-I HQ · 8K	~1,000 Mbps	~450 GB

VENICE 2

VENICE 2 · 25 fps
Codec & format	Data rate	Per hour
X-OCN XT · 8.6K 3:2	~6,670 Mbps	~3.0 TB
X-OCN ST · 8.6K 3:2	~4,670 Mbps	~2.1 TB
X-OCN LT · 8.6K 3:2	~2,670 Mbps	~1.2 TB
X-OCN LT · 4K UHD	~242 Mbps	~109 GB

All rates approximate, from Sony spec sheets. GB per hour = Mbps × 3,600 ÷ 8 ÷ 1,000. Actual sizes vary with scene complexity, firmware and settings.

Record time on Sony media

80 GB CFexpress Type A · FX3 / FX6 · 4K UHD 25 fps
Codec	Record time
XAVC S-I (All-Intra)	~42 min
XAVC HS · 200 Mbps	~53 min
XAVC S · 100 Mbps	~1h 47m

A 160 GB card doubles these times. VENICE 2 records to AXS media; BURANO and FX9 to CFexpress Type B — check the calculator above for those combinations.

Which media does each camera take?

VENICE 2 records X-OCN to AXS memory. BURANO and FX9 use CFexpress Type B. FX6, FX3 and FX30 use CFexpress Type A (Sony Tough G) or V90 SD cards depending on codec. Always add roughly 20% headroom over the calculated total when ordering media — reloads never land exactly on card boundaries.

Sony data — quick answers

How much data does a Sony FX3 record per hour?

At 4K UHD 25 fps: XAVC S-I (All-Intra) runs at about 250 Mbps — roughly 113 GB per hour. XAVC HS (Long GOP HEVC) at 200 Mbps is about 90 GB per hour, and XAVC S (Long GOP H.264) at 100 Mbps is about 45 GB per hour.

How many minutes fit on an 80 GB CFexpress Type A card in an FX3 or FX6?

At 4K UHD 25 fps: about 42 minutes in XAVC S-I, about 53 minutes in XAVC HS at 200 Mbps, or about 1 hour 47 minutes in XAVC S at 100 Mbps. A 160 GB card doubles those times.

How much data does VENICE 2 X-OCN record per hour?

At 8.6K 3:2 25 fps: X-OCN XT is about 3.0 TB per hour, X-OCN ST about 2.1 TB per hour and X-OCN LT about 1.2 TB per hour. At 4K UHD 25 fps, X-OCN LT drops to roughly 109 GB per hour.

Which cards do Sony cinema cameras use?

VENICE 2 records X-OCN to AXS memory (AXS-A1TS66 etc.). BURANO and FX9 use CFexpress Type B. FX6, FX3 and FX30 use CFexpress Type A (Sony Tough G) or V90 SD cards depending on the codec.

Are these Sony data rates exact?

They are close approximations from Sony specification sheets. Actual file sizes vary slightly with scene complexity, firmware and settings, so add around 20% headroom when ordering media for a shoot.
