Use the Keyer-3D node to key out a given range of colours. The 3D Keyer provides a high level of control over the settings of the key. You can also view your animation data in the Universal Channel Editor.
You can access the Keyer-3D node directly from Batch as well as from the Modular Keyer.
The Keyer-3D node accepts a front clip as input. You use it as the key-in clip, to create a matte for the front clip.
The Image Type box adjusts the algorithm based on the Image Data Type of your media. See Adjusting Algorithms Based on Image Data Type.
