The Pixelate effect lets you apply a mosaic effect to an image (and its matte) based on the matte you supply. Pixelation makes the image look like it is made up of square tiles.
The Pixelate node takes an image of any type in the right (Image) input port, and a matte drawing in the left (Matte) input port. It outputs a version of the input image where the parts of the image that intersect with the matte are pixelated.
The Pixelate node requires a matte drawing. If you want to pixelate the entire input image, simply connect it to both the Image input port and the Matte input port.
Allows you to enable or disable the node. When disabled, a node has no visible effect on the rendered image, nor on the preview in the Camera,
Sets the colour of the layer in the Timeline view
The name of the node as it appears in the Node View and the Timeline view. Each node must have a name that is unique to its containing group.
Inverts the matte used to generate the effect. By default, the effect is applied to the opaque areas of the matte drawing. When this option is enabled, the effect is applied to the transparent areas of the matte instead.
The pixelation factor. This parameter takes a decimal value between 0 and 1. The higher the value, the bigger the pixels. The default value is 0.0125 and creates sizeable pixels, so this parameter must be set to low values unless you want the pixels to take up the whole stage.
