Looks like the new version of Final Cut supports 4K resolution and RED camera natively.

If we weren’t already using After Effects for our final edit, I’d move us over to Final Cut since we’re doing our sound design with Logic and Soundtrack. But we may soon have access to a RED camera so it’ll be nice to pull in footage to Final Cut for editing. I’d love to hear from people who have used Final Cut for their 4K footage. What do you think?
