Hi. I've been working with Magic Bullet Looks 3.0.4 and Colorista 1.0.4 on Premiere Pro CC 2014 since a month ago and I never had any problem until now. Now everytime I add one of those effects to a clip a black frame appears on the preview and I can't see the changes I'm just doing. If I set the pause resolution to 1/2, the preview comes back to normal.
I opened a project that I was working on before when I had no problem at all with looks and colorista and the project and the preview of the clips it's completely normal, even in full resolution. I added a new clip to this same project and later apply the effect and the black frame appears again (but only on this new clip).
It's really a problem when I need full resolution, I hope you can help me.
