Set it once: 4K 16:9 at 30p, H.265 4:2:2 10-bit at 100 Mbps, shutter 1/60, Auto ISO capped at 3200, ETERNA, manual Kelvin white balance, OIS on. Then stop adjusting and start filming. Photography guidance and video guidance are genuinely different disciplines — this module keeps them apart on purpose.

What the camera can actually record
| Mode | Resolution | Frame rates | Sensor crop |
|---|---|---|---|
| 6.2K open gate (3:2) | 6240 × 4160 | 24, 25, 30p | 1.0× |
| DCI 4K (17:9) | 4096 × 2160 | 24, 25, 30p | 1.0× |
| DCI 4K (17:9) | 4096 × 2160 | 50, 60p | approx. 1.18× |
| 4K UHD (16:9) | 3840 × 2160 | 24, 25, 30p | 1.0× |
| 4K UHD (16:9) | 3840 × 2160 | 50, 60p | approx. 1.18× |
| Full HD | 1920 × 1080 | 24-60p | 1.0× |
| Full HD high speed | 1920 × 1080 | 100, 120, 200, 240p | approx. 1.29× |
The shutter rule, concretely
For natural motion, set the shutter to about double your frame rate: 1/60 s at 30p, 1/50 s at 25p, 1/120 s at 60p. Faster looks stroboscopic; slower looks smeared. In bright daylight that fixed shutter will overexpose even at f/22, which is what a variable ND filter is for — a 52 mm one, since that is your filter thread.
Heat, battery and cards
| Mode | Reported runtime | Source type |
|---|---|---|
| 6.2K open gate 30p | approx. 1 h 15 min, stopped by the battery | Reviewer |
| 4K UHD 30p | Over an hour at about 24 °C | Reviewer |
| 4K 60p | Overheats in roughly 40 min | Reviewer |
| 4K LP 30p at 25 °C ambient | Over an hour | Fujifilm |
| 4K LP 30p at 40 °C ambient | About 20 min | Fujifilm |
| 4K 60p with the optional fan | Roughly doubles, to about 1 h 25 min | Reviewer |
- Three heat levers: AUTO POWER OFF TEMP. set to HIGH (Fujifilm warns this can cause low-temperature burns, so use it on a tripod), the LP recording modes, and the optional FAN-001 cooling fan.
- Battery: Fujifilm’s own movie figures are roughly 45 min at 6.2K/30p, 50 min at 4K/30p, 45 min at Full HD 60p.
- USB-C power works while recording — but use a Power Delivery bank, not a plain 5 V one, and note that USB power adds heat.
- Cards: Fujifilm recommends U3 for 4K. A UHS-I V30 128 GB card gives about 85 minutes at the top bitrate.
The camera’s real video weakness
There is no in-body stabilisation. Fujifilm’s spec sheet lists only Digital Image Stabilisation, with IS MODE BOOST in movie mode. Every “why is my footage shaky” question traces back to this. Digital stabilisation helps, but it costs you a crop, and it cannot fix a walking bounce.
Audio, exposure and colour
- Audio: the internal microphone is usable, with a front-priority direction setting for talking to camera. A cheap external mic in the 3.5 mm jack is the single biggest quality upgrade available — audio matters more than resolution.
- Exposure: keep the shutter fixed and control brightness with aperture, ISO and ND. Cap Auto ISO at 3200; base ISO for movie is 125.
- White balance: set a manual Kelvin value. Auto white balance shifts mid-clip, and there is no fixing that gracefully.
- Colour: ETERNA if you intend to grade lightly, PROVIA if you want it finished in camera. F-Log exists, but it is not a beginner’s tool — skip it until grading is something you enjoy.
