What is rotoscoping masking?
Masking is the process by which you draw or import a spline shape to define an alpha matte (Figure 3.1). Rotoscoping simply adds animation to the mask so that it changes shape over time.
What is roto paint?
RotoPaint is a vector-based node for help with tasks like rotoscoping, rig removal, garbage matting and dustbusting. You can draw Bezier and B-Spline shapes with individual and layer group attributes, including per-point and global feather, motion blur, blending modes and individual or hierarchical 2D transformations.
How do I create a roto shape in rotopaint?
Click the Bezier tool in the RotoPaint toolbar on the left side of the Viewer. Then in the Viewer, click four points around the goldfish to create a roto shape. You can drag+click to draw a point and adjust its curve at the same time. Tip: As long as the RotoPaint1 control panel is open, you can view and edit the roto shape.
How do I use the Roto shapes as masks?
An optional image to use as a mask. By default, the roto shapes are limited to the non-black areas of the mask. At first, the mask input appears as a triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. If you cannot see the mask input, ensure that the mask control is disabled or set to none.
How do I select individual input channels for Roto shapes?
If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels. Premultiply multiplies the chosen input channels with a mask representing the roto shapes. For example, where there are no roto shapes (the matte is black or empty), the input channels are set to black.
How do I adjust the feathering of the Roto tool?
Press E to increase the feathering of selected points, or Shift + E to remove the feathering. If you check feather link in the Roto tool settings above the Viewer, you can move the shape point and the feather point together.
