Rolling Shutter Correction
Rolling shutter correction helps reduce distortion where vertical lines bend or wobble when the camera moves.
For external camera workflows in Gyroflow, using a value close to the camera's sensor readout time can make gyro-based stabilization look more natural.
iPhone-Only Footage
For iPhone-only footage, the rolling shutter effect is relatively small, so it is usually okay to leave rolling shutter correction unset at first.
If vertical lines, building edges, or shelves wobble unnaturally, adjust rolling shutter correction in Gyroflow Desktop.
iPhone Measured Values
The following values are measured by independent third-party labs (CineD, Slashcam). Use these as starting points and confirm with your own test footage.
| Model | Lens | Frame Readout Time | Notes |
|---|---|---|---|
| iPhone 15 Pro | 24mm main | 5.3 ms | Worth correcting |
| iPhone 15 Pro | 13mm ultra-wide | 4.7 ms | Worth correcting |
| iPhone 15 Pro | 77mm / 120mm telephoto | 5.0 ms | Worth correcting |
| iPhone 16 Pro Max | 24mm main | 2.4 ms | Very fast — correction usually unnecessary |
| iPhone 16 Pro Max | 13mm ultra-wide | 5.8 ms | Worth correcting |
| iPhone 16 Pro Max | 120mm telephoto | 5.5 ms | Worth correcting |
| iPhone 17 Pro | Main — 2160p (24–60 fps) | 2.3 ms | Very fast — correction usually unnecessary |
| iPhone 17 Pro | Main — Open Gate 4224×3024 | 3.1 ms | Very fast — correction usually unnecessary |
| iPhone 17 Pro | Ultra-wide / 100mm telephoto | Not yet measured | Use 5–6 ms as an initial estimate |

External Cameras
For external cameras, the rolling shutter value can change depending on the camera body, resolution, frame rate, crop mode, and recording mode.
Use this order when choosing a value:
- Look for a measurement from the same camera, resolution, and frame rate.
- If the exact mode is not available, start with the closest resolution or crop mode.
- Check a short test clip with vertical lines or building edges.
- Fine-tune the value in Gyroflow Desktop if needed.

Published values may not exactly match your recording mode. Always confirm with your own test footage.
What To Check
- Building edges
- Door frames
- Shelves
- Poles
- Distortion near the edge of the frame
If the value is too strong, the image can look less natural. Adjust it on a short clip first.
