System information
Mode Description Example
Lighten Compares the overlay and background pixel by pixel and
selects the lighter color value for each pixel.
Difference Compares the overlay and background pixel by pixel and
subtracts the darker color value from the lighter color to
generate a new color value.
Difference
Squared
Remaps color values along a parabolic curve. The color values
of the layers in the composite group are subtracted, and then
the subtracted values are squared.
The resulting image will have less extreme changes in color
values as the colors approach black (RGB 0,0,0) and more
extreme changes in color values as colors approach white (RGB
255,255,255).
Drag the Level slider in a video track to control the transparency or blending of each track. Left is 100%
transparent and right is 100% opaque. You can also double-click the percent to enter a specific numeric
percentage.
Using a 2-to-1 transform plug-in for custom compositing
When you click the Parent Composite Mode or Compositing Mode button and choose Custom from
the menu, you can use plug-ins to customize compositing.
The included Displacement Map, Height Map, and Bump Map plug-ins can create interesting lens, mirror,
water, fire, and other light-bending effects.
Plug-In Description
Displacement Map Uses the parent image as a guide to offset the pixels in the
composited child tracks along the horizontal and vertical axes.
The X and Y offsets are independently encoded in the image color
channels.
Height Map Uses the parent image as a guide to make the pixels in the
composited child tracks appear closer to or farther away from the
viewer.
The gradient of the image in the parent track is used to determine the
amount of offset for the image displayed at that location, in much
the same way light bends through a lens.
Bump Map Uses the parent image as a guide to add texture and lighting to the
composited child tracks.
The texture of the bump map is applied to the composited child
tracks: light sections of the map represent high areas, and dark
sections represent low areas.
