The framed area in the Universe view represents what is visible in the Tracks pane in the Edit window. If you change what is displayed in the Edit window—by zooming, scrolling horizontally or vertically, hiding or showing tracks, or changing track heights—the framed area in the Universe view relocates and resizes accordingly. During playback, if the Edit window is set to scroll, the framed area in the Universe view also scrolls.
When all tracks are visible in the Edit window and the session is zoomed all the way out, with all clips visible, the entire Universe window is framed.
