Shuffle
Shuffle lets you:
- rearrange up to 8 channels from a single image (B input). For example, you can use it to swap rgba. red for rgba. green, and vice versa,
- rearrange channels between two separate nodes (A and B input), like a foreground and background branch.
- replace a channel with black (removing the alpha channel, for example) or with white (making the alpha solid, for example),
- create new channels.
PlanarTracker
PlanarTracker is a powerful tool for tracking surfaces that lie on a plane in your source footage. Planar tracking is often better than tracking individual points (with the Tracker node for instance) as it takes a great deal more information into account and gives you a more accurate result. A rigid surface, like a wall or a side of an object, are good planes to track. You can use your tracking results to replace the tracked plane with another image for instance. You can define the region to track by creating and animating roto shapes.
Conerpin 2D
The CornerPin2D node is designed to map the four corners of an image sequence to or from positions derived from tracking data. In practice, this node lets you replace any four-cornered feature with another image sequence. You can use it to place an image in an on-screen television, for example.
Before using this node, you should use the Tracker node to generate four tracks, one per corner, on the feature requiring replacement.
