Picture-in-Picture Transition
This transition is used to place a video clip inside another video clip. By default, the second clip is placed inside the first clip. Select ' Swap video clip for this transition ' to see the first clip placed inside the second one. It is helpful to think about the Picture-in-Picture transition in terms of Foreground Video and the Background Video. Depending on the 'Swap video clips for this transition' option, either the second clip (default) or the first clip will form the Foreground Video.
The Picture-in-Picture Transition uses two rectangles to position the foreground video clip on the background video clip - The View Rectangle and the Bounding Rectangle. Both these rectangles relate to the foreground video clip. The Background video clip cannot be changed.
View Rectangle
The View Rectangle controls the position of the foreground video clip on the background video clip. The position is measured in terms of pixels. To specify a view rectangle, either move or resize the rectangle using the sizing handles, or enter the Left and Top locations (for the top-left corner of the rectangle) and the Width and Height.
Bounding Rectangle
The Bounding Rectangle also applies to the foreground video clip. This rectangle defines the part of the foreground video clip that shows up and fits in the View Rectangle.
For example if the Bounding Rectangle is placed at the top-right quarter and the View Rectangle is placed at the bottom-left quarter then the top-right quarter of the foreground video clip will show up at the bottom-left quarter on the background video clip.
Many pre-set configurations for the Picture-in-Picture Transition are available. To use one, select it the Presets box. Click " OK " when done.
Make View Rectangle and Bounding Rectangle size same
When this option is checked, the dimensions of the View as well as Bounding Rectangle become the same.
Swap video clips for this transition
When you apply this transition, the second clip appears over the first clip. Check this option if you want the first clip to appear inside the second clip.
