24FPS

Support

Koka’s camera. 4K. 24 frames per second. Apple Log 2. HEVC. Point & shoot.

This guide describes the latest 24FPS build. Some features may not yet be available in the version installed on your device.

Start shooting

Tap the record button to start; tap again to stop. The three dots reveal the advanced controls. The eye clears the preview of controls and overlays that cover the image.

Camera mode requires iOS 26 and hardware that supports 4K/24 Apple Log 2 capture. Remote mode requires iOS 18 or later; an older iPhone or iPad can be your monitor even when it cannot be the camera.

Exposure, focus and lenses

In advanced mode, choose a parameter and use the slider. Shutter runs from 1/24 to 1/60 second, defaults to 1/50, and remembers your choice. ISO, white balance and focus have an A control: tap to enable automatic adjustment; tap again to hold the current value manually.

Tap the focal-length button to choose a lens preset. Available presets stay usable while recording; switching physical cameras is blocked during a take. Stabilisation can crop the image. Displayed focal lengths account for that crop where calibrated, and remain approximate.

Grids and overlays

Open the grid selector to choose a composition guide. Repeated taps on the golden spiral cycle its mirrored arrangements. The level, math-paper grid and diagonals are independent overlays, so they can accompany another grid. White/black and thin/thick controls adjust visibility. Tap outside to close the selector.

The level follows the real horizon. Align its cross with the screen’s horizontal reference to lock it yellow. When aiming straight up or down, it becomes a two-axis target: align the two crosses. These guides do not appear in your recordings.

MON groups focus peaking and zebras. Peaking helps judge focus; zebras mark bright areas before the monitoring LUT. They are a highlight guide, not a calibrated guarantee of sensor clipping.

Motion detection

Set the camera on a stable support and compose a reasonably still shot. Hold the record button for two seconds to arm motion recording. A yellow button means armed and ready; a hollow yellow button with an orbiting arc means settling or waiting. Red means recording, with the usual elapsed time.

Movement starts a clip. After three seconds without detected motion, the clip stops and the camera rearms automatically. Tap record to disarm. Leaving filming mode also disarms it. There is no pre-roll: the clip begins when motion triggers recording.

The SEN slider has five levels: 1 is least sensitive; 5 is for micro motion. Start at 3. This detects image changes, not particular people or animals. Moving leaves, water, shadows and screens can trigger it too. In dark areas, subtle motion may be harder to distinguish from noise. If autofocus keeps disturbing a static shot, try locking focus after composing.

Choose what to track

While motion mode is armed, tap the mask button beneath SEN. The first time, a zone appears. Drag on an empty part of the image to create more zones. Drag inside a zone to move it, an edge to move both connected corners, or a corner to reshape it independently.

Green zones include areas; red zones exclude them. Select a zone and tap the colored square beside the trash icon to switch its role. The square shows which type the zone will switch to. Exclusions take priority wherever zones overlap. With no green zones, the whole image is included except for red exclusions.

Tap trash to delete the selected zone. Hold trash to confirm clearing all zones. Tap Done beneath SEN to finish editing and rearm. Sensitivity and zones are remembered. Motion triggering pauses during zone editing.

Voice control

From version 1.2.0, say “Camera start” or “Camera stop” while the camera is open. Two rear-torch flashes confirm the start; four confirm the stop. Start flashes may light the scene in your recording.

Voice control is on by default. Turn it off in Settings → Apps → 24FPS → Voice control. Recognition runs on the device in English; Apple may download a speech model on first use. It pauses during motion recording, media review, background use and microphone interruptions. It resumes with ordinary filming.

Preview LUTs

LU/LUT switches between the base Apple Log 2 conversion and KODAK 5207 (or your imported Custom LUT). Both are for viewing: live monitoring, the remote feed, clip playback and thumbnails. Your recorded footage remains Apple Log 2.

Use your own LUT

Send a 3D .cube file to the camera iPhone by AirDrop, or open it from Files in 24FPS. iOS may show an app chooser. Check the filename and tap Use. One imported LUT replaces the Custom slot; importing another replaces that import. The bundled KODAK 5207 LUT remains available to restore.

Use a LUT authored for Apple Log 2 input and Rec.709 output. A creative LUT expecting Rec.709 input is not a direct replacement. The app checks the file’s structure but cannot infer its intended color space.

Supported files are UTF-8 3D .cube LUTs, 2–65 points per axis, up to 32 MB. Combined and 1D LUTs are not supported. A rejected import leaves your existing LUT intact. Finish recording before applying a change.

To return to KODAK 5207, hold LU/LUT for one second and confirm Restore. Import and restore happen on the camera device; the remote receives its monitored image.

Review and share clips

Tap the media thumbnail to browse. Clips run from oldest to newest; the browser opens at the newest end. Tap a square to view the video, then swipe for the previous or next clip. Swiping continues playback only if you were already playing.

Select enters selection mode. Tap individual checkboxes, or use All/None. Use the share or trash control for the selected clips; Done returns to filming. Allow Photos access so the app can save and show your recordings. Limited access shows only the clips you have allowed.

Pair a remote

Choose Camera on the filming phone and Remote on the monitoring device. Open the remote’s QR button, point the idle 24FPS camera at its code and tap Pair. The QR closes after pairing. You can remember several remotes and use one connection at a time. Scanning a remembered remote offers Unpair.

Keep Wi-Fi enabled on both devices and allow Local Network access. Monitoring does not require internet access. Reconnection is automatic when a usable connection returns; walls, interference and distance still affect the link. If it does not return, bring the devices closer and check that both apps are open in their intended roles.

Troubleshooting

If saving to Photos fails, keep 24FPS installed: the recording may have been retained in app storage. Do not delete the app to troubleshoot a retained recording. Check free storage and Photos permission, and contact support.

For help or feedback, email contact@koka.one. Include your device model, iOS version, app version, the exact message and the steps that led to it. For motion issues, include the sensitivity and whether zones were used. For LUT issues, include its size and intended input/output color spaces. Send private footage only if needed and you choose to share it.
