Hithere, thanks for having me. This is my first post. If I am doing anything differently than you are used to or would like to see let me know.
So I am just getting into videography. I flew my drone into the sunset as a time-lapse and expectedly had to adjust exposure by increasing ISO as it got darker. My drone only lets me chose complete exposure values so the steps down are sudden and unsightly. I am looking for some sort of exposure ramp that would let me smoothen things out, I have looked all over the internet, so I decided to check in here to see who knows.
There are a few ways to deal with this, most of them a bit laborious depending on how drastic the changes are and how often they occur. Basically you need to color correct/exposure adjust over time so the transition is as subtle as possible. If you are using FCPX as your NLE, take a look at this tutorial by Ripple Training to get a starting point.

Handling exposure changes in a time lapse is a common issue, whether the time lapse is a series of stills or a video, and whether the exposure changes are from changing light or the camera making sudden step changes.
If your time lapse is a series of stills you can process those with various software to try and even out the changes. One of the best apps is LRTimelapse:
When you convert the time lapse to a video within FCPX you could try Digital Anarchy's Flicker Free plugin. I have used it successfully to smooth out the sudden exposure changes from some DJI drones. However it is very CPU-intensive to run.
