I've been using both Color Finale and Chromatic for color grading, but Chromatic seems to need much more time to render than Color finale. I'm using a macbook pro 2,3 ghz late 2013 with 16gb RAM, and 2gb VRAM. Just wondering if this is happening also to others or is just my config. Yesterday I was working with 4k clips and some titles, and the clips that were graded with chromatic took a massive amount of time to render.
Between the beta test team, aside from the late 2013 Mac Pro, we found Chromatic was faster, or as fast as Color Finale. I know that Coremelt will have an update or two coming that will also increase performance. This is a fledgling add-on, and there's lots that will be done and added over time.
Contact Coremelt's tech support, give them your Mac specs, and other info, they'd be glad to hear from you and see what's going on.
