You may be better served posting this question on the Sony Vegas forums below:
There are some resident experts on that site that they advertise and they may have the answer to your question, sorry I couldn't be of more help.
If you still don't get the help needed there, I would personally contact Sony with this question as they would ultimately have the best answer for you and any possible tools or tips.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
