I have deleted a lot of things from the C drive as well as move Creator NXT 7 to my D drive. I am using the trial of Video Studio and like it. But after I pull up the Multi-Camera Editor and make a few changes it still is freezing. It was installed on the C drive. I do not think I can reinstall the trial to the D drive. Would that even help?
Not sure if you still need an answer, but in NXT 7, if you select one of the provided overlays, adjust its size and right click on it - you have the option of saving it as a custom overlay. Hope that helps.
Actually, in Production Editor - Timeline, double select the Split Screen Template Creator clip in the Video track. Click on Internet Track. You can lengthen the Ovl 1 or Ovl 2 track which you want to be longer by dragging on the green dot at the end of the clip. You can play with this and figure it out.
