Lately I've been having an issue when rendering clips with Lumetri Color. I'm working with AVCHD footage from a Canon c100. I notice that if I add two Lumetri Color effects to one clip and use a mask on the effects, it will export with a flickering problem over that clip. When I remove the effects, the issue goes away on the render. I tried deleting my render files and that did not work.
I did find another thread that said to change the Video Rendering setting to Software only (not OpenCL). After I did that, the video exported perfectly and there was no flickering. I guess what I am wondering is is this an issue with Premiere or is this a Graphics Card issue? I have a Mid-2014 Macbook Pro with a NVIDIA GeForce GT 750M. I would hate for this to be my GPU.
Has anyone else encountered this problem? What can I do to solve it?
