Vegas allows one to insert a timecode display that counts up as the track progresses. What would be an easy way to generate the same type of effect that counts down to zero at the end of the track?
I created this a decade ago. Still works. Used to be available at VASST, but they long ago removed everything from their site. Here's a VEG file that will show you how it's done:
You can set the starting time, which pieces of time to display (such as Hours and Seconds only) and check the "count down" button to count down instead of up.
