DSLR iris lighting issues in video??
I have some video I am trying to edit. It’s travel footage shot out doors on a Nikon D7000. When editing the footage I am noticing consistently that when the camera is panning I am getting sudden lighting differences from the camera iris. It’s not a lens flare, more like the camera is compensating to adjust for lighting conditions or the metering is self adjusting (even though it was shot on Manual mode).
What is the best/most efficient way to edit this on FCP and correct the video. I don’t just want to cut the pieces out. Is there any manual workaround to smooth the quick changes in light?
Thank you in advance for any advice!

None that I know of.
This is largely why virtually no pro shooters EVER use auto-iris.
If the iris is “hunting” constantly, you will have random changes over time – and there’s no reliable way I’ve ever seen to “auto ramp and clamp” those changes back to a steady overall brightness.
It makes sense when you think about it, because no “auto” system can tell whether random increases and decreases in overall brightness is coming from something you don’t want (the action of the iris) rather than something natural in the frame you do want – like moving toward and across a window or doorway, or the reveal and hiding of a white shirt moving across the frame.
This is why we pay competent shooters. They understand that manually adjusting something from a fixed state is always WAY easier than adjusting it from a variable one.
FWIW.
