Work natively with the video same playback functionality as previous versions, meaning there will be less on worrying about rendering.
Buy Final Cut Pro instead. To put it lightly, this is the best professional video editor out there.
CS4 is available for both Windows and Mac. Cons Adobes brilliant team has engineered well working media programs to become a worthless conglomeration of software. It handles a number of different codecs wonderfully. I like this even better than Final Cut Pro from Apple. Adobe Premiere Pro CS5.
