LUT Preview Turns Gray During Recording on iPhone 15 Pro Max

PostFri May 02, 2025 1:32 pm

Device: iPhone 15 Pro Max
iOS Version: 18.4.1
Blackmagic Camera App Version:2.3.000047
Mode: Apple Log enabled
LUT: Display LUT enabled (tested with default and custom LUTs)
HDR Video: Disabled in system settings

When I prepare to shoot in Apple Log mode with a Display LUT applied, the preview looks correct (colorful, with LUT applied). However, as soon as I press the record button, the live preview immediately switches to a flat gray Log appearance — as if the Display LUT is being disabled. The recorded video itself is unaffected and retains the correct look, so this appears to be a preview-only issue.

I’ve confirmed this behavior across different LUTs, even after restarting the app, reinstalling it, and rebooting the phone. The issue persists consistently.

Could you please confirm if this is a known bug or an intentional limitation? If it’s a bug, do you have any ETA on a fix?
