After setting the drawing options, you can draw the mask.
To draw a garbage mask:
- Access the Garbage Mask menu.
- Select the view where you want to draw the mask from the View box.
Which view you use depends on the context of your key and why you are drawing the mask. For example, if you want to crop the
edges of a clip by drawing an opaque mask around the subject and then turning on Outside, try drawing the mask using the Matte
view. Or, if you are rotoscoping a subject that has not been shot on a blue or green screen, try either the Front or Result
view.
TipIn Batch or the Modular Keyer, you can use multiple viewports as you draw the garbage mask. For example, you can draw the
mask in Matte view, while also displaying Result view. Using multiple viewports, you can immediately see how your mask affects
the clip.
- Do one of the following:
- Click Add.
- Select Create from the Edit Mode box.
- Press
N
.
- Do any of the following to draw the garbage mask:
- Press Shift to temporarily hide the vertices and tangents as you are drawing the mask.
- Click-drag to control the tangency of any vertex as you are drawing the mask. When you release, you can continue to add vertices.
- Shift-drag to add freehand segments to the mask. The vertices and tangents of the mask you are drawing are temporarily hidden.
Vertices are added where you drag, and appear when you release Shift. After closing the mask, you can use the Lasso Fit parameter to increase or decrease the number of vertices that define the
freehand segments of the mask. See Adjusting the Number of Points in Freehand Segments.
NoteIf you are drawing the mask with Auto Tangents turned off, freehand segments are drawn with broken tangents. See
Breaking Tangents.
- To close the mask, do one of the following:
- Click Close.
- Click the first vertex.
- Drag to the first vertex.
TipYou can also close the mask by pressing the hotkey for the edit mode you want to use next: M for Move, S for Select, or B for Break. The mask closes and you are ready to work in that mode.
When the garbage mask is closed, its vertices and tangents can be edited and animated.
If you want to view the nodes that are added with each new garbage mask, select Schematic from the World View box or press
the ~ key. You can use the Schematic view to access a menu, create parent-child relationships between masks and axes, delete masks,
as well as perform other organizational tasks.
