I made a project in VP19 Build 643 that is 4:30 long. Smartsound music, some Boris Gamma, SeMW and various transitions from Boris. Vitascene Pro 3, and GL. Just 2 tracks... video and music. Opening in VP19, 5.4GB of RAM is being used.
Copying the same project from VP19 to VP18 Build 527, same settings in Preference, Project and anything else I can think of, RAM usage when on the timeline is 1.8GB.
I checked to make sure all the "stuff" I did was present in VP18, and it was. The RAM usage didn't make a difference if I started VP18 first or VP19. Now, I am wondering "why" the huge difference in RAM usage.... I'm open to suggestions.
I became aware of this when trying to add Vegas Slow Motion to a short test clip in my VP19 project. I watched RAM go over 11GB.
For me, something is wrong with the way VP19 is using RAM compared to VP18....
