Hi, if I have a group of pictures in a catalog which I have process (clarity, contrast...), tren I export metadata, can I import these pictures from LRTimelapse in the way I see them in lightroom?
Instead of import again these pictures from LRTimelapse.

Thanks in advance!!

Yes, but they will miss the LRTimelapse initialization then and that might cause problems in the further process.
I suggest to start the workflow in LRTimelapse with the initializian and edit the keyframes again. This is normally way quicker then to notice after a long render process that something went wrong.
