Sony A7r III - Timelapse & Auto Exposure problem

[Mattbar_95]

Hi thank you for welcoming in the forum,
I would like to disable the AE when using interval shooting but it is not possible it is just Low, Medium or High.

I took some timelapses at night and it's just full of jumps.
For example here is a jump. The only difference that I notice is the Exposure value.
04924.ARW = Exposure value -10,233
04925.ARW = Exposure value -10,166
It's a small change but it's unusable for me.

You can see in the screenshots also all the rest of my camera settings.

Do you have any suggestions?
Should I just take videos instead at night? How can I stop this from happening?

Thank you
Best
Matt

Time lapse sets always have choices you have to make. As for "jumps" well, to an extent that is the result of the time gap between frames, so it is a natural part of process. You might want to use a fixed aperture and leave exposure changes to shutter speed and ISO. Personally, I might prefer using the "S&Q" setting except on my a6400, "S&Q" time lapse is 1080p, which is disappointing. If your camera has a 4K/UHD version of time-lapse in "S&Q" then that's what I would suggest. I would also suggest trying Slog2 (exposure probably at +2.0) or maybe one of the Cine settings, and then re-adjust in post. If your camera is limited to 8-bit video then avoid Slog3 which will usually give a poor result.
