The time lapse referenced below is the second time lapse I attempted with one of my D7200s. It was taken with the lens set to 18mm, a frame every 3 sec, 1/320 sec, f 5.6, and ISO 100. This one was done in video mode.
A previous one was done with successive stills, full resolution, then converted to jpeg. To get a movie out of it, I used ffmpeg on a Linux platform.
Both show variability in apparent illuminance of frames.
I was surprised that I observed that variance in this shoot, which was done in movie mode. I would like to get the mechanics down before I run off to specific locations to recreate the sunrise with more interesting subjects.
Any ideas why the variability in apparent illuminance in some frames?

Set the ISO to a fixed value.

It looked to me that the sun reflected off, or shown through the clouds at a variable rate. I wasn't there, but that is what it looked like to me. Very nice product.
