Re: Survey: How would you want FCP X and FCP 7 compatibility to work?

Simple to say but maybe hard to program . . .
On import the user has the option to make the additional Video Tracks Connected Clips or Secondary Story lines. The additional audio would have to be Connected Clips.
Nests would come in as Compound Clips.

Apparently this is very hard to program or Randy wouldn't have said what he said.

Part of the issue may be although that superficially the new Storyline structure works like a sequence, it's "guided" by the rules of AV Foundation so the underpinnings are probably very difficult to translate. In other words a Storyline programmatically is nothing at all like a sequence.
