Often when trying to process a timelapse in Lightroom it will be hard to get the exposure etc. correct at both the start and end of a sequence due to changing lighting conditions. Usually I just process as best I can then export as 16bit tiffs and key the grade settings in AfterFX when I'm compiling the timelapse. This, however, does not give as good a result as could be achieved if one could key the settings in Lightroom.
This is where LR Timelapse comes in. I've been meaning to try it for a while but I don't really do enough timelapse stuff to warrant spending money on it.
Then the other day I came across this:
https://github.com/lewisthompson/timeroom
The python scripts should work if you're on a Mac, and have Python installed, and there is a link to Windows binaries half way down the page.
It's really basic and it has a weird workflow (easy once you've done it once though) but it does exactly what I want. That is it allows me to process the first frame of a timelapse and the last frame of a timelapse and it will tween the values between them.
Here is a timelapse I did on the weekend, the second and third shots in it were done using this software and I'm very happy with the result.
