Hi

I just wonder what the workflow is for going back and editing in Lightroom a second time is.

I did a short segment the other day, and created the short video in Lightroom, as per the standard workflow.
I then realised that I should change a few things.

So I open LRT again and played around..i eventually got the effect I wanted, but only by starting from the beginning once more and doing the whole thing again.

I wanted to re-define the exposure area and add some more keyframes

Do I have to hit the initialise button when I open my folder of images or do i 'Reload' and then go back up to the 'Def-Ref Area' and skip the "Initialise"

You can skip the initialization the second time.
