Fancy?
In Sound Forge we have an option of a pre-region sampling - great!
How about some of the same for Vegas? Altering an Event: CC, Colour Grading, Bez and so on . .  I have just done a bunch of these, and I was wanting to SEE/FEEL just what preceded (or even followed!), in Preview.
That would give me more control and be consistent with SF too.
Now Bob is going to tell: "Well, Vegas needs to time sample and it can't work" or some such reasonable "can't do" reason.
Just thought you'd like to pick up on this fantastic idea and feedback. Get enough support for it and I'll sending a pigeon over to Madison.
Grazie
PS: Vegas Rox!
EDIT - spilling! What else?
