Just a follow up, I have upgraded to 8 GB RAM (maximum for my machine) and made sure it took. When I import all of the assets into Premiere and then try to play an HD clip on the timeline, I am getting some freezing of the image but I still hear sound. I’m wondering if I am bringing too many clips into the project. The project is also set up as a 1080 sequence. If I create an SD sequence, will Premiere have an easier time with the HD assets? I’m only making DVDs anyway. I’ve tried showing the images at 1/4 and 1/2 quality, but it still seems like an issue. If I can get through this project without buying a new PC, I’ll have a year before I have to complete the same volunteer project. Anybody have any suggestions to get the smoothest playback possible at this point? Thanks!
