Thats correct Mike, the files are truncated to the timeline length + handle size which is user settable and is for the start and finish of the clip. The file is an embedded .omf file, and yes a Pro Tools needs digitranslator to open it but a pro tool swithout digitranslator is a car with 3 wheels really.
Although I accept Ty’s possible suggestion of exporting track files as .wavs or aifs, this idea is a real donkey as you lose the handle data, at which point you might as well just finish it in the FCP if you insist on tying your hands behind your back and making life harder.
NB Pro tools 8 is out very soon and the upgrade cost from any previous PT to Pt8 is a give away price of only about £150 for an HD system and even less for an Le system, and i think it includes digitranslator as standard now.
I always get editors to give me all wild tracks and music cues used full length on the end of the sequence when they export for a dub, that way i can access all that additional data within the omf timeline.
