Nice features, but really want:
(1) Library System ABOVE Events/Projects, similar to Aperture so you can have different library's (and each library would have its own events/projects. The unified system is foolish and causes a lot of lag. There is NO REASON to open everything all the time, especially when many events have nothing to do with each other.
(2) Chapter Marker Support.
I know I've sent feedback about this one too. Glaring omission.
(3) Revamped Compressor that automatically uses all cores like Handbrake does. VBR encoding would also be nice.
lol compressor has to be one of the major failings. I had a nice 'chat' with one of the final cut team members about this one. Just ridiculous that their own software won't automatically utilize the power they so tout about their mac pros. Asinine, is how I remember describing it to him. For DVD output, I actually still output qt files and use Bitvice, which - like Handbrake automatically recognizes and utilizes all power without begging it. To me, this is like asking the Death Star to fire up it's big laser to destroy Alderaan and only using 1 of the 4 or 5 laser beams.
For H.264 files, i use Matrox's CompressHD card.
Don't even get me going about cluster computing. When I think of Apple and cluster computing, I think of it as a major cluster *****.
(4) Actual Background Rendering to occur while working.
(5) In/Out markers to stay on clips.
(6) Markers for clips already used (similar to iMovie).
I love the overall approach to FCP-X, so anything they add is welcome.
