I agree completely!!! Whenever Adobe has made changes in their non-video programs (such as Photoshop or Illustrator) vital shortcuts were maintained. In times when shortcuts were dropped, they always reappeared again in the next version (due to the outcry of the John Q. Public).
That being said, I have used PremPro CS4 for a few days now, and I’ve dropped it like a hot potato. I initially switched some of my post production from Final Cut to PremPro CS3 and found it saved me quite a big of time because rendering was not required to view HD clips – even when several filters had been applied. Not only is CS4 slow, buggy, and unstable (crashing over and over again), timelines MUST be rendered when layering clips or adding filters – unless of course you are fond of watching your video out of sync with your audio.
All I could think when I excitedly began working with CS4 was, wow – great new interface – hope the rest of it’s as great! NOT! How disappointing and what a waste of money! If I’m going to need to render everything, I will gladly return to Final Cut for all my post production.
