System information
Mode Description Example
Multiply (Mask) Merges the colors of the tracks.
Source Alpha Uses the alpha channel to determine transparency.
The compositing mode is based on the alpha channel
characteristics of an event or media file. If no alpha
channel is present, the Source Alpha mode has no effect.
Add Combines the color values in the composite group.
Subtract Subtracts the overlay color values from the background.
Cut Cuts out the overlay color values from the background.
Screen Multiplies the inverse of the overlay color values with the
background color values. This makes overlay colors weaker and
less present and results in a lighter video image. The opposite of
this mode is Multiply.
Overlay Heightens contrast by using Multiply mode on darker colors
and Screen mode on lighter colors.
Hard Light Adds overlay colors as if the overlay were lit by a bright,
focused spotlight.
Dodge Brightens the background based on the overlay color values.
Burn Darkens the background based on the overlay color values.
Darken Compares the overlay and background pixel by pixel and
selects the darker color value for each pixel.
