I have created a composite of 5 tracks that I would like to use in various new projects. This composite is created with filler material and uses nested tracks and track motion to manipulate the material. I would like to be able to insert this composite into multiple places in a master project with each instance having its own specific material. So far I can't even insert a single instance. Here's what I've tried:

1. I brought up two instances of Vegas, one with the composite and one with my master project. I copied the five composite tracks and pasted them into the master project. This created the 5 tracks in the master project but did not preserve the nesting or track motion key frames.

2. I tried bringing in the composite as a nested VEG but this causes Vegas (version 6D) to lock up. Even if this worked, I would have to create a copy of my composite veg for each new instance since each instance uses unique material (i.e., new takes).

-------------------------------------------------------------------------------------------
EDIT: I found an old post that suggested this lockup can happen if the nested VEG is having problems finding its media. I replaced my fillers with generated media and now the composite VEG nests properly in the master.
-------------------------------------------------------------------------------------------

Ultimately what I am trying to achieve is a way to create a few nice composites I can use over and over with material specific to each instance of use. I want to reuse the track keyframing and composite settings. So far, the only way I can see to do this is to create a new copy of my composite, add my material as new takes, render to avi, and add this avi to my master project. Anyone know a better way?

Thanks,

Jerry
