Hi, I've made a couple of time lapses with the new version and it takes ages to sort out the luminosity after loading in a new set of pictures. I've been waiting nearly 10 minutes just for 350 picture to load in, where as the last version was a lot faster. The visual preview is a lot better, but I'm also finding the deflicker isn't working very well now. I'm having to refine sections numerous time to flatten it out, where as the old version used to run in a lot more linear fashion.

I'm using a macbook pro with El Capitan and a SSD plus 10gig of memory with an i7 quad core processor.

Which versions are you talking about? (4.7 (current) vs. 4.6 or 3.x ?)
Whicht kind of pictures? jpgs are always slower then RAW files / DNG files)
Deflicker didn't change in the 4.x versions.

You should increase the memory provided to LRTimelapse on your mac, see faq:
