Will my FCP 5.0 project files open in FCP 7? Obviously I never upgraded to FCP 6 or 7 and my FCS 1.0 software won't work on my newer Intel Macbook Pro. Lately, all my editing has been with Adobe PP, Sony Vegas (and iMovie if you want to count that).
Now that's a completely different question which no one here knows the answer to. I'd guess probably not, at least not in the same way an FCP 5 project can open in FCP 7.
