Using Masks in Colour Correct and Colour Warper Timeline FX
When the matte clip is used as a mask,
it defines where to apply the Colour
Warper Timeline FX on the RGB clip.
A Colour Warper Timeline FX is applied
to the matte container. By default, it
creates a transparency.
The RGB clip will be added to a matte
container with a matte surrounding the
talent.

You can change the default functionality of the matte clip and instead use it as a mask to isolate the area
in which you want to add colour effects and corrections.
In the Colour Corrector or Colour Warper quick menu, enable the Use Mask button, which uses the matte
to delimit the region that will be processed with the colour effects.
NOTE When Use Mask is on, all mattes generated before the Colour Correct or Colour Warper Timeline FX are
ingested for use in these effects as masks, and matte functionality is no longer available for Timeline FX used after
it in the pipeline.
Using Mattes in Comp Timeline FX
When the Comp Timeline FX is disabled
or the matte is turned off, only the RGB
clip is displayed.
In a matte container containing a logo,
The Comp Timeline FX is active by de-
fault. An image of a gladiator was
stacked on a track underneath, so it is
composited in the result.

All mattes used in the Timeline FX pipeline for the segment are composited using this effect. The composited
mattes for each segment can be turned on or off, or be inverted.
A clip can be in a premultiplied or unpremultiplied state. An unpremultiplied clip has its pixels divided by
the pixels in the matte. A premultiplied clip has its pixels multiplied by the pixels in the matte. Use the
Comp Timeline FX quick menu or the editor to set the Segment and Background Premultiplication boxes
to the appropriate states.
