I’m running into a frustrating exposure/brightness flickering issue with my DJI Action camera mounted on a 7-inch quad, and I’m hoping someone who has run into this can point me in the right direction.
The Issue: During flight, the video records with a rapid, continuous exposure/brightness flicker (almost like a fast strobe effect). It looks like auto-exposure constantly hunting between slightly overexposed and underexposed frames.
Key Context & Setup:
- Drone: GEPRC Moz7 V2 (7-inch long-range quad)
- Camera: DJI Action camera mounted in a standard TPU mount on the top deck
- Power: Running on the camera’s internal battery (no external BEC, balance leads, or power cables connected)
- Propellers: Props are not in the field of view
Camera Settings (All Fully Locked Manually):
- Resolution & FPS: 4K @ 60fps (1/1 aspect ratio, Wide FOV)
- Shutter Speed: Locked at
1/200
- ISO: Locked at
100
- Aperture & White Balance: Fixed / Manual
- Color Profile: D-Log M 10-bit (Enhanced Bitrate)
- Stabilization: OFF (RockSteady / HorizonSteady explicitly disabled)
The Catch / Diagnostic Fact:
- The flickering happens only when the drone is flying/vibrating.
- On the exact same drone, during the exact same flight, my DJI O4 Pro Air Unit footage is completely clean (no jello, shift, or exposure flickering at all).
Has anyone resolved this on a 7-inch setup? How did you damp or isolate the mount to fix it?
Thanks in advance!
