It is a must read for an Final Cut Pro 7 switcher. And has some great stuff on using it with an external monitor with either a Kona or a Matrox (seems Kona works better, but still has issues, especially with a long sequence).
Check it out if you get a chance. I am already making the switch to Premiere Pro CS5.5, though I am having issues with Lion, and this points out some issues I had not realized that you have to think about.
I hadn’t realized Premier Pro doesn’t have any sort of Auto Media Relinking, that each clip must be manually found. Of course with how slow Final Cut Pro 7’s could be, this might actually be faster.
No timecode window, which is a must, though was not added all that long ago to FInal Cut Pro.
Reveal in Project from Source Window! A no brainer since you can do it from the sequence!
Check out the whole article. It is worth checking out.
