vegas pro 12 project veg. file not opening

[Des Swot]

This post has really put me onto the correct workflow and i thank all the members that contributed.

Originally I used to create a single enormous veg. file and render out from there.I won’t begin to tell you how many problems and weird fx have been ironed out by be now importing the single veg. files from within vegas.As Nigel also advised,the master veg. file auto updates as you continue editing the individual veggies.

I am busy doing my final render which takes three hours (it is a 2 hour movie)but the workflow has been amazing with no crashes at all in vegas 12.I find it is a big step up from vegas 10.
