I'm using the latest version of Premiere CC and can't get Immersive Video Transitions to work. When my project setting is "Mercury Playback Engine GPU Acceleration" and I use an Immersive Video Transition, every clip in my entire sequence is affected. That did not happen in the last version and I have not changed anything. If I change the Project Settings to Software Only and use Immersive Video Transitions, I get a message that says "this effect requires GPU acceleration". I have seen others submit a issue similar, but the answer has been to change the Project Settings, I've done that and cannot seem to get JUST an Immersive Video Transition to work. Help!
