Good day yall,

Question, I have been shooting whales with drones for a couple years.  One thing I notice is that when I am shooting top down of them in the ocean and they make a splash ( Which produces highlights that werrent in frame before ) the sensor appears to try and save or recover the video exposure  by darkening the rest of the vid.  I shoot on manual everything.  I have my white balance, iso, shutter, fstop set to manual but cant seem to reconcile what mechanism is creating this flicker.   

I have posted a short clip of what I am speaking about.  I would love some feedback if anyone has any idea or suggestions.  Shot at 4k 60fps.  With ND 8 polarizer.  at 1/120 SS.

Theoretically it shouldn't dothat, butit;s so subtle that if you didn't mention it I wouldn't have noticed.

If you are shooting manually, it shouldn't do this.

I raised an issue a while back with my drone's exposure ticking up and down, but it was for a single frame.

Hopefully you already record your footage with 'subtitles' which is where the drone saves a .SRT file with all your clips. This file will show you the exact metadata for your video and you can check it frame by frame to see if the exposure changed.

Might I suggest that you flash your firmware and hopefully you won't see this happen again. If it does, then you'll have your SRT files to send to DJI to prove that the exposure changes, as your video shows something changed automatically.

Thanks for the response.  I will check into that and see if I can start using the SRT files to start checking frame by frame.

Hi there. Thank you for reaching out. May I know what is the firmware version of your drone? I will forward this to the relevant team to check. Thank you very much.

Hi Mate.

I am having the same issue with my Mavic 3 Pro.

It has done it from day one, and I have done several updates to it with no improvement

I notice one gentleman suggested that he woudn't have noticed if it wasn't pointed out, and this could be part of the answer

What I mean by this is, you & I obviously notice it, and it drives us nuts, but some people don't even notice it

So I can't help but wonder if the guys trying to look into this complaint, can't actually even see the problem

It's a real problem for me, because you have to either edit that section out, (which is not good when you have some great footage), or leave it in

I choose to edit it out, which is pretty annoying because it's usually in a great section of footage that I often can't replicate again

Have you had any luck fans3093c6d9 ?

Hi Mate.

What’s up man. unfortunately no I did not. although a user suggest above something about checking srt files to confirm but i don’t know how to do that. And same it may be small for us but i shoot manual and it’s clearly an exposure change. i noticed it specifically when shooting whales and they go from under water to making a splash which brings out highlights in frame that were not previously there. and thus the rest of the exposure goes darker. no fix yet on my end.

The SRT will have the answer for you. If you shot in manual then there's an issue.
