However, PRE11 seems to be much cleaner and faster. There is very little lag in response time and my old problems of dropped frames, uneven pans, and errors have vanished. To get an accurate preview of the edited video you have to render the Timeline, which used to be a slow process and not always successful. Now the Render tab is on the top of the Timeline and is much more responsive and effective. The preview plays accurately and there are no unpleasant surprises by the final product during publication.
