To Paul, I experience the same problem. I roto brush 3 minutes of a music video. I’m working on a macbook pro with 4GB of ram. I upgraded to 8GB and it only improved slightly. So I decided to focus on roto brushing a few seconds at a time and that works great. So I would agree with everyone, the more ram the better (16GB+) might be the way to go.
