Keying: Motion

Those of you familiar with other versions of Primatte Keyer will find most of the familiar controls in the Keying section. As its name suggests, this is where all of the keying functions are located. The Motion version works similar to the After Effects version with controls in the Filters interface in the Inspector window and sampling done in the Project window.

Interface

The Keying interface is provided in a series of buttons that you use to choose the sampling mode.

• View

• Selection

• Correction

• Refinement

There are several sampling controls within each keying section. This area on the interface allows the user to change the view in the Project window...

Auto Setup

The Auto Setup is a new feature in Primatte Keyer Pro 4. It is an artificial intelligence algorithm that tries to figure out the backing screen color (blue or green), eliminate it and then tries to clean up any noise in the foreground object and the backing screen area. Ideally, the user should only have to do some spill removal as a last step in using Primatte. There are many things in a foreground clip that can interfere with getting a good result and if the initial result is not an almost clean key, then the user should perform a Reset and start the Primatte over using the standard four step operation (Set BG Color, Clean BG Area, Clean FG Area and Spill Minus).

Reset

The Reset button is the little curved arrow icon in the upper right hand corner of the Primatte filter and is used to reset all the Primatte parameters and start you back with a green or blue screen image. If you want to reset just the keying parameter, use the large Reset button next to the Reset Key category. This button only reset the custom sampling colors for Primatte Keyer but leaves other parts of the plug-in in their current state.
