Hi guys,
I have a weird color error on a Mavic 3M multispectral. All firmware up to date to the latest version. I attach you some photos, maybe you have already seen something like that?
The error appears always on 5-4 photos, when I do surveys. It started in November 2023. Usually when I start the survey, and the drone comes back to replace battery, the error appears at the beginning of the second flight. When I do the image processing with Pix4D, the error is present on the ortho as well.
Thanks in advance if you have some ideas!
Cheers from Hungary,

Those are corrupt files, could be from a bad SD card failing to save the data. Maybe try another one (check that if fulfills the right speed specs) and see if it happens again.
 
I am also having some M3M color issues and found your post. My issue is a bit different, I'm getting some raw images that appear more blue than expected. For example, I have 2 images that were taken near each other in respect to both location and time. The DNG images are large, so I've attached darktable screenshots that show the different coloring. I've noticed the exposure and fstop values are quite different as well as the color plots in the upper-right corner. Is this a sensor issue, clouds, or something else? I haven't experienced this before and am not sure how to correct it or what to check.
