we are in the process of doing exactly what you wnat to do. We have finished cutting our filma nd plan to do a film out soon. I am runnign a bunch of tests with a post house next week. If you shoot me your e-mail I can let you know how it turns out. Our footagwe was taken in via firewire and cut using FCP5.0. We are trying three tests:
1) spit out uncompressed quicktime 10bit 4:2:2
2) lay back to tape
3) lay back directly to D5 from FCP (we have a Kona LHE…great )
we do not have many disolves or effects so either way we are going to dump out of FCP we are plannign on doing diolves by spititng out an AB roll and then doing them in the Nitris or Smoke.
if interested shoot me your e-mail and I will let you know how it goes.
