This panel shows the movie files that are in the timeline. This behaves just like a monitor would as you drag the scrubber along the timeline. To make this panel larger, close any other panel that is in Quadrant 1 or Quadrant 2. This will make the Preview panel the entire width of the software.
The aspect ratio will follow whatever you chose when you first created the project - IE Anamorphic.
On the RIGHT SIDE of the panel are the following buttons:
Maximize - this will make the panel the entire size of the software. Once this button is pushed, it is replaced with the minimize button.
Minimize - If the panel is maximized, the minimize button will replace the maximize button. Clicking on this button will return the panel to it’s original state.
Close - this will close the panel (Hotkey - Alt+1)
