User Manual

A node tree set up to feed an EXT MATTE node’s RGB output to the input of a node
connected to a Layer Mixer, in order to blend it with the grade using composite modes
5 Right-click the Layer Mixer node, and choose Overlay from the Composite Mode
submenu to blend the Ext Matte node most effectively with the grade.
6 If necessary, you can use the grading controls of the Corrector node to which you’ve
attached the EXT MATTE node to change the characteristics of the texture clip,
desaturating it for instance. You can also select the EXT MATTE node itself, open the
Key palette, and use the Transform, Offset, Loop, or Freeze controls described later to
change how the matte appears.
The resulting texture effect, blended with the grade
using the Overlay composite mode
TIP: If you want the texture you create to be unaffected by blur or sharpening
operations within the grade, be sure to add it to the very end of the node tree.
Using External Mattes to Create Transparency
You can also use an EXT MATTE node to create transparency in a clip, for compositing with
clips underneath it on the Timeline.
To use a clip matte to create transparency in a clip:
1 Right-click any node, and choose the attached matte you want to use from the Add
Matte submenu of the contextual menu.
Adding an EXT MATTE node to a Clip grade applies the effect to only that clip, whereas
adding an EXT MATTE node to a Track grade applies the effect to the entire Timeline.
