Macworld Reviews Final Cut Studio 2 (Updated)

UPDATE: Macworld added their review for Compressor. Highlights of Compressor 3: Optical flow does good job frame rate conversion (e.g., 60i to 24p), easier clustering (including on one system), streamlined interface (oh no, does that mean we have to bid adieu to Batch Monitor!?), watermarking, more formats supported.

MacWorld has revews of all the new apps in Final Cut Studio 2, except for Compressor. Worth a read, especially if you haven't been keeping up on what's new in these Apps

Motion 3
I think the first paragraph really sums up the value of Motion:

Motion, Apple’s motion-graphics and video-processing software, has always stood apart not so much for what it does but the way it does it. In many visual and video tools, you spend much of your time preparing graphics and then watching rendering progress bars, but Motion’s workflow is built around real-time adjustment and experimentation. With Motion 3, Apple has focused on the major capabilities previous versions lacked: motion tracking and stabilization, painting tools, and a true 3-D graphical environment to augment speed and easy, improvisational control. Motion may not become your only motion-graphics program, but it could easily become your favorite tool for quickly creating visuals

Color
Caveats galore for Color--just because you edited something in FCP doesn't mean that it will work in Color. This article doesn't even mention the problems with the HDV format that the Creative Cow mentioned. I imagine when I start using Color, it would just be for a shot or two at a time and not taking in a whole project. So far, this is how I've also used...
