Your nested files are what is causing Vegas to keep freezing, when its on
the timeline in a project.
I no longer work with Nested Vegas files anymore because of this happening
sometimes. So what you do John is simply render out your individual nested
files that are included in a project and let them retain the original names, then load your project with those new rendered files instead…. You will
have no more issues.
