Final Cut Pro 4, Shake 3
chasingporsches writes "It appears that Apple released Final Cut Pro 4, Shake 3, and DVD Studio Pro 2. FCP4 has great new features, such as updated HD support, but unfortunately the usual hefty price tag ($999 full, $399 upgrade). Shake now has unlimited network rendering, and DVD Studio Pro 2 has a new basic/advanced user interface."
One thing not mentioned at all in the summary of the new parts of FCP 4 is the new Soundtrack component, which in my opinion could justify the upgrade and the price tag of the entire suite all by itself. This lets anyone, regardless of musical experience, write fairly complex scores for their movies. Essentially, you get a vast library of super-high-fidelity loops that you can then combine with surprising ease straight into your FCP project. You can see the demos/tutorials here. Note that QuickTime and a fast connection are required.
