Expoting FCP Multitrack to STP

Whenever I try and send my FCP project as a Multitrack project into STP, it doesn't work. My project is an hour long, it just will not open in STP. it freezes and does not respond.

But when I do smaller clips and sequences it works just fine. It seems that anything I do over 10 minutes causes a problem.

Can someone please help me.

I know it has nothing to do with the power of my system. i am running a G% dual 2.7 with 4GB of RAM.

I'm assuming that you did log & capture in a proffessional manner not a capture now of a whole tape , then DV start stop detection.

We'll need more info on the nature of your tracks to have an idea of what's likely the problem.
