Without the Duck?
Here’s a way that won’t cost you anything to try.
Export XML from FCP, then import that in to DaVinci Resolve Lite. Export from DaVinci Resolve to Avid (via AAF). Resolve even makes Avid media.
Will it work? I’ve made it work on short simple sequences, not an entire film. Won’t cost you a cent to try.
I’d give you a better chance of success with the current version of Avid than an old one though.
Why do you need to do this?
