I shot in manual but am noticing the exposure changing rapidly in several clips rendering them unusable for the project I'm working on. I shot about 30 clips and only notice this in a few in the video below.

Initially I thought it was the camera adjusting due to the props being in the first shot but remembered I shot in manual. I then found examples of flickering without the props in the frame (last two shots), which ruled that out.

I dug up a few other forum threads and saw that auto white balance could be the culprit which is what I typically use when shooting. Would that be the best place to start for troubleshooting? I'm not even sure how I would test it since it's intermittent. Guidance appreciated.
Here's a link to the clips that were flickering:

Hi there. Thank you for reaching out and we're sorry for the trouble. Propeller shadows occur when flying outdoors, especially when using the aircraft in direct sunlight. Please try to bring the aircraft to a different location and have a test flight to see if the issue persists. Also, please try to back up all the files on your SD card and please reformat it then check if the issue persists. If you have a spare SD card, please try that as well to further isolate the issue. Please keep us posted. Thank you.

Hi Paladin, Thank you for your response. Some points I either didn't address in my first post or want to reiterate:

None of the 3+ minutes of footage I shared were shooting into direct sunlight. They were shooting away from the sun or in soft lighting. First clip had props in the shot. Other two did not. Again, I shot 27 clips and only three of them had this issue (and there were many of the rest of the batch that were shot directly towards the sun with no problems). Also, I was using the same SD card for all of them.

Please let me know if this changes your thoughts and advice on the issue as I want to make sure I do not go down a rabbit hole based on generic troubleshooting advice. I've flown P4Ps for 5 years and haven't run into this until this shoot. That's hundreds of flights on multiple drones.
**Edit: some timestamps that it is most visible:

After watching this again (especially that last one), it appears that the sky and sand are flashing but not the buildings. How is that possible and what does that mean?

Looks like shadow from the props in the beginning.
But the last shots are weird indeed.
