I routinely have to wait between 3-8 minutes while Premiere 'does its thing'. I understand this kind of project would be processor intensive. Also lots of split screens and motion effects. My projects typically have between 3 or 4 and up to 25 different videos imported, some high-res, others scaled up to fill the frame, edited in to several hundred clips with video and audio tracks. Most of these live on an external drive with USB3 connection. I'm compiling 1280x720 sequences from a wide variety of sources, mp4, wmv's, m4v, avi's. How to get Premiere to use all the RAM I have? Even though I have 32 GB of RAM installed, my OS Activity Monitor app shows that Premiere is using only 1.5 GB at any time.
Premiere constantly hangs, drags, virtually freezes up and makes editing somewhat torturous.
