|Summary||0000260: Masks and Rotoscoping|
|Description||In the secondary Color Correction you have to isolate a part of the frame where to intervene leaving the rest unchanged. The main ways of doing this are Blue Banana and rotoscoping. I would like to implement this second method in CinGG because it is extremely powerful, useful and easy to use. The principle is to create a mask whose content is the only one affected by the changes (and monitored by the videoscopes) while the rest of the frame remains unchanged. This is done by creating a matte in the alpha channel so that the changes relate only to the solid part (white).|
The basic features of these "power windows" are:
1- Preset shapes: rectangle, ellipse and freehand.
2- Control of edge blending from the outside and inside. Practically a second internal mask and an external third mask representing the (editable) borders of the gradient.
