Prior to the Ver 15 release, my project would load very quickly. After the update, my project takes several minutes to load. I have tried two different iMacs, a brand new Mac Mini, and two different hard drives for the media. I have created a new project from scratch with new media. I suspect the issue involves the closed caption tracks and the new closed caption workflow. I capture my footage live and it has embedded closed captions that I need. Each show is between 1 minute and 5 minutes so nothing huge. After the project loads, it works fine. In one month, my project will have around 100 captured files, but Premiere will claim it has around 3x that amount to load. Please help fix this.
