Sources Settings
If a source node is parented above a surface node in the schematic, the Source tab is available. These settings
allow you to change source settings on a per surface basis, independent of the source type set in the Source
menu for the parent source node or nodes. See
Replacing the Front or Matte Clip (page 671).
Changing the Shape of a Surface
When you first activate media or access Action, the media's surface is set to Flat by default. In Action, you
can also represent a clip using custom bilinear or extended bicubic surfaces.
To change the shape of a surface:
1 Double-click the surface in the Schematic view.
2 Select the shape of the surface from the Shape box.
3 Click the vertex you want to edit and drag it to its new position.
You use the verticesor handleson surfaces to change a surface's shape. You can move, rotate, shear,
and scale a surface using the
Axis (page 497) menu.
