View Resize Image in the Segment Properties - Horizontal & Vertical Slider
In the Segment Properties window, you can use the vertical / horizontal offset sliders to adjust the relative placement of a video in the Preview Window. This is very useful when creating a Collage Effect. Collaging allows you to show two or more videos / images together, be it side by side or one over another.
Note each track has a corresponding collage button. For collaging to occur both this button and the track collage button must be engaged.
If the slider has the keyboard input focus, you can use the arrow keys to achieve greater precision.
By right-clicking on the sliders, you can restore them to their original positions.
