It's amazing how many suggestions have been offered even though it's not even clear that there is an actual problem that needs fixing.
- do a factory reset of the drone and controller, and reinstall the app on your phone/tablet.
- It might also be worth trying a different SD card
- your record frame rate may be too low
- go to your drone settings and reset the camera
- I had a similar problem with my Mini 1. I stripped down the gimbal and camera. Replaced the cables and the problem was gone.
- I also had a similar problem. Still don't know what was wrong with it, but I sold it
- You need to adjust your video setting. On your remote. Other option looks like to much light and settings will help also a polarized filter on the camera will help.
- It looks like a filter is turned on or something. Did you buy the drone new, is it still in warranty? I would contact DJI and start a return. If it's outside warranty as someone else suggested, replacing the cable from the camera to the board may fix it.
- Its overexposed. reset your exposure setting
- Have you checked your “White Balance “?
Clearly they can't all be correct
Almost all of them (maybe all) are quite wrong.
All of these helpful suggestions are just guesses without any idea what the problem might be (if there actually is a problem).
Why do people imagine that making blind guesses is helpful?
