You can use Comp Timeline FX to control the composition and display of the output matte used in the
segment's Timeline FX pipeline. In the editor, you can view the composited matte, and edit how it is blended
and premultiplied.
TIP You can set the default premultiplication setting for the segment, background, and output of timeline Comp
effects in the Timeline FX / CFX section of the Preference menu.
Adding Matte Containers
A matte container is a container with the RGB portion of an image on one track and its matte on another.
If the matte for a clip exists separately from it, you can add the clip and its matte to the timeline as a single
element by creating a matte container for them. You can also create matte containers on import, or from
the Tools tab.
To create a matte container on the timeline:
1 In the timeline, select the clip you want to add the matte container to.
2 In the Timeline FX pipeline, select the proxy for the clip.
Underneath the pipeline, a quick menu appears.
3 Click the Add Matte button.
4 Select a matte from the workspace. The Matte Container button appears in the Timeline FX pipeline.
If the matte media length is equal to the front length, then the matte segment is positioned at the
same start as the front segment. If the matte media length is different to the front length, then the
matte segment is positioned at the Container segment start (yellow marks).
5 To open the Matte Container, click once on the Matte Container button and then click Open in the
quick menu, or double-click on the Matte Container button.
Once the Matte container is open, you can adjust the settings for the matte or add other effects to it.
6 If you want to mute the matte, right-click the Matte Container button and select Mute.
7 If you want to remove the matte, click once on the Matte Container button and then click on the
Uncontain button.
NOTE If you use the matte container clip in ConnectFX, the front and matte clips are present in the clip node.
Working with Mattes and Masks on the Timeline
Masks and mattes increase the versatility of the effects you apply on the timeline, allowing you to delimit
the regions used for processing and effect, with a mask, and to create regions of total or partial transparency
in the clip, with a matte.
