In the next example, clicking the Make Compositing Parent button () on track 3 forces the track below (at 
the same compositing level) to be rendered in 3D and composited as a 2D image.
Track 4 (green-and-gray checkerboard) now has the appearance of depth—the checkerboard tapers to a 
vanishing point—but is inserted in the composited output as a 2D image at a depth of zero on the Z axis. 
Track 2 is still rotated in 3D space.
In the next example, clicking...

Creating image masks
You can use media generated by Vegas software to create simple masks. You can also create masks from just 
about any image file.

2.Add the mask image file as an event into the top-most track on the timeline.
3.Insert a video event just below the mask track. This is the background video behind the mask and is the 
event that is...

Creating video masks
You can also use video files to create masks, although the process can be more complicated than using an 
image as a mask. The key to any mask is contrast. You can increase the difference between the light and dark 
areas of a video file using video effects plug-ins.
1.Insert the video that you want to use as a mask into a video track.
2.Drag a Black and White plug-in from the Video FX window to the event to remove the color. For more...

Using the Mask Generator
The Mask Generator is a plug-in that controls the transparency of events to be used as masks when you use 
events that are not grayscale. Apply the plug-in to an event (or a track) in the same way as any other plug-
in: just drag-and-drop. The Mask Generator plug-in can be found in the Video FX
 window (from the View 
menu, choose 
Video FX).
How the Mask Generator works
The following illustration demonstrates some of the effects...

The top-right example uses luminance to determine the transparency in the mask. The white area is 
completely transparent. Since white is made up of 100% values of red, green, and blue (255,255, and 255), 
those three colors are all 33% transparent as well. In the lower-right example, blue is the selected 
transparent index. The blue area is 100% transparent and so are all areas that have a value of 255 for blue 
(0,0,255), including white (255,255,255)....

Note: Other effects that can change the color of the event 
should be bypassed when using the Eyedropper tool.
