Xpress Pro is a great little app… I known it’s been used to cut a couple studio features films not too long ago. As an offline cut station there’s no reason to waste big $$ on the high-end Avids. But it suffers from 1) if you’ve never cut on Avid, the interface and editing workflow seems VERY antiquated and mechanical, and 2) we’ve found it to be VERY picky about the exact setup and software versions of your computer.
Don’t let Avid’s PR buzz about “industry standard” sway you. Their reign of terror is fading away. We had 6 full blown Media Composers in house, now we have 1 and 5 FCPs. If I were you, I wouldn’t even think twice about staying FCP.
