Is it possible to add gaps of any length between videos? This is due to the fact that with batch render > render regions, the last second of the previous video is at the beginning of each next video.
I'm attaching a screenshot with an example of what I mean.
You can try Vegasaur - Quick Properties - Placement - At Intervals
How to download this script?
Just type it into Notepad.
@Hawk-Thomas You should not get 1-second overlaps between multiple clips dropped on the timeline together unless you checked the box in editing preferences: Automatically overlap multiple selected media when added. And then created regions ending at what appears to be clip boundaries. Also, if you want Vegas to automatically put spaces between multiple clip dropped together, in addition to unchecking that box, also enable Quantize to frames. That tends to put a 1-frame space between clips dropped together if they don't end on a frame boundary.
Fwiw, I use batch render regions all the time to render song-regions out of concert videos and have never seen the problem you describe, even when songs abut one another in medley.
