To create a video matte in Ruby Mask mode:
Select the first frame of the video you want to apply the matte over.
1.
The frame appears as an image in the edit window.
Click the Ruby Mask mode button on the Standard toolbar or View:
2.
Display Mode - Ruby Mask. A ruby film appears over the image.
Select a paint tool and define its attributes in the Brush panel (see page
3.
42).
Start painting over the mask. The areas affected are removed from the
4.
mask revealing the underlying image. If your painting removes too
much of the ruby mask, click the Erase button in the Shape tab of the
Brush panel. Now when you paint, the ruby mask is applied.
Select the next frame and click Edit: Duplicate Last Paint Layer.
5.
(The paint layer from the previous frame is copied to the current
frame.) Once duplicated, you can start painting on it as in the previous
step.
Repeat steps 4 and 5 until the matte is complete. (If the object you are
6.
creating the matte over does not move, then you only need to paint one
frame.)
Change display modes to see your changes and click the Save button
7.
on the Standard toolbar or File: Save to save the project as a UVP file.
If you are going to apply the matte in Video Editor, you need to replace
the source video with a solid color so that you can better key out the
background and foreground.
