Rob, I’m glad you found it interesting.
As you may have noticed, the tutorial was written for Vegas 5 so you know it’s old ????
The author was a Sony Vegas employee. For all I know he’s still working in Madison.
I remember coming across it a very long time ago and it’s one of those that got stuck in my head!
I did a search on here for it and found that I had suggested it 12 years ago.
Have fun with it ????
