Choose frame rate for the motion effect you want, set shutter speed around twice the capture frame rate as a starting point, and size storage from the bitrate of the exact camera mode. Don’t assume a camera records 4K at 240fps: the resolution, crop, codec, card requirements, and recording limits vary by model and setting.
Choose the capture frame rate for the finished video
Start with the playback frame rate and the motion you want. If you want slow motion on a lower-frame-rate timeline, capture at a higher frame rate and play the footage back at that lower rate. The captured action then takes up more time on the timeline. For normal-speed motion, capture and delivery rates usually do not need to differ just because the camera offers a high-frame-rate setting.
Check the camera’s mode table before planning a shot. A camera may offer 4K at 120fps but only HD at 240fps. For example, GoPro lists 4K 120fps and 1080p 240fps for the HERO12; that is a product-specific example, not a universal capability. See the HERO12 specifications.

Set shutter speed for the motion you want
Use the 180-degree shutter as a starting point
A familiar starting point for natural-looking motion is a 180-degree shutter angle. Exposure time is calculated as shutter angle ÷ (360 × frames per second), as stated in the ARRI ALEXA 35 User Manual. At 180 degrees, that works out to about one over twice the frame rate:
- 120fps: 180 ÷ (360 × 120) = 1/240 second.
- 240fps: 180 ÷ (360 × 240) = 1/480 second.
If your camera does not offer those exact increments, choose the closest available shutter setting. Sony, for example, gives 1/250 second as a 120p example and describes twice-frame-rate shutter speed as a guideline, not a rule. See Sony’s shutter speed guidance.

Adjust for blur, light, and flicker
A faster shutter reduces per-frame exposure and motion blur, making moving subjects look sharper or more staccato. A slower shutter increases blur. Depart from the 180-degree starting point when the scene’s motion, desired look, or exposure needs call for it.

Short exposures such as 1/240 or 1/480 second collect less light than a slower shutter. Balance exposure with aperture, ISO, and available lighting; in bright conditions, suitable filtration may also help, depending on the camera and lens. With mains-powered or other flickering light, test the actual frame-rate and shutter combination. Sony warns that flicker problems can occur when flicker timing does not coincide with shutter operations; there is no single anti-flicker setting that can be assumed to work for every region and fixture.

Estimate storage from the exact mode’s bitrate
Use the bitrate for the selected resolution, frame rate, codec, bit depth, and chroma mode—not a generic figure for “4K.” Sony’s α7S III specifications, for example, list approximate 4K 120p rates of 200 Mbps for 10-bit 4:2:0 and 280 Mbps for 10-bit 4:2:2 in XAVC HS. These figures apply to those camera formats, not to all 4K 120fps recording. See the α7S III specifications.
Estimate decimal gigabytes with this formula:
Approximate GB = bitrate in Mbps × recording seconds ÷ 8,000

At 280 Mbps, one minute is approximately 2.1 GB. Actual files also use space for audio, container overhead, file-system formatting, and camera-specific variations. Multiply the per-minute estimate by your expected recording time and leave room beyond the result.
Capacity and write speed solve different problems: capacity determines how much footage fits; sustained write speed determines whether the camera can keep recording that mode. Panasonic’s GH7 instructions say high-frame-rate VFR recording increases recorded data volume and that recording may stop if card writing speed is insufficient. Available rates also depend on resolution and compression mode. Check the GH7 instructions for the selected setting.

Choose a card using the camera’s mode requirements
Use the camera manual’s card table for the precise recording mode and codec. Confirm the supported card type and capacity range, bus or interface, speed class, and any minimum sustained write rate. For instance, Panasonic’s EVA1 instructions list SDHC/SDXC formats and supported UHS and video speed classes; GoPro specifies a microSD card rated V30 or UHS-3 for the HERO12. Those requirements are model-specific. Consult the EVA1 instructions and the HERO12 specifications.
A faster card may exceed a camera’s minimum in some modes, but buying a high rating does not establish compatibility or make that rating necessary. A V90 SDXC card, for example, should not be treated as universally required or universally compatible. Nor is an advertised peak speed proof of sustained write performance. Match the card to the camera’s stated requirement for the mode you intend to use.
Compare modes before committing to a shoot
Before recording, compare the actual options in the camera menu or manual:
- Resolution available at the target frame rate.
- Codec, bitrate, bit depth, and chroma mode at the selected quality.
- Any documented crop or field-of-view change.
- Card type and minimum sustained write-speed requirement.
- Recording-time or thermal limits.
- Delivery frame rate and the resulting slow-motion factor.
These details can change between modes on the same camera, as well as between models. Verify the current manual and specifications for your camera, firmware, region, and intended recording format rather than relying on a general 4K or high-speed label.
