Hi Mate.
The only 2 things that spring to mind are 1, you have a file open with the same name. Not likely i know.
The second is something i came across the other day. I was trying to render some files that were shot at 24fps and i wanted to render out to .mp4 at 24fps. I just kept getting a generic message saying Vegas couldn’t do it. Dropping the fps to 23.976 worked like a charm.

Im pretty new to all this but i found it strange and couldn’t figure out why it was doing this.

Good luck finding the answer.

Dave.
