Keying: View Controls

The two View Controls are used to designate what image mode you see in either your Filter window or your Canvas window.

Filter Window View Controls

While using Primatte Keyer you will need to switch back and forth between different views to accurately build your matte, and this menu is where you can switch between viewing the unprocessed foreground image and the current matte.

There are two main components to this View menu.

• FG tells Primatte to display the original foreground in the Filter window. The current composition is displayed in the Canvas window and is the keyed foreground element over the background element (consisting of one or more layers in the FCP composite). This image does not get updated but gives the user a place to make samples to complete the keying operation.

• Matte tells Primatte to display the matte as it is currently being generated and is used to clean up foreground and background noise.

The Matte view here will only display the matte when the Canvas window view control is set to Final Output. Otherwise, it will be a blank white image.

Canvas Window View Controls

While using Primatte Keyer you may want to switch back and forth between different views to accurately build your matte, and this is another menu is where you make your view choice. This View Mode menu changes the view in the Canvas window.

There are six main components to the Canvas Window View Mode menu.

• Final Output tells Primatte to display the current composite in the Canvas window. The current comp is the keyed foreground element over the background element (consisting of one or more layers in the FCP composite). It usually looks like this...

• Matte tells Primatte to display the matte as it is currently being generated. For the image above, the matte would look something like this...

• Preprocessed Foreground will display the processed foreground view in the Canvas window. It only displays the output of the Primatte filter and not the background image (even if one is attached to the filter). The view shows the foreground against a black background usually with a lot of false coloring or noisy pixels around it. The noisy pixels are generated to maintain the fine hair or thin foreground detail. Because the matte around the noisy pixels are very small and will be multiplied against the noise, the end result will be highly desirable. The main purpose of outputting the processed foreground is for ’multi-layered compositing’. If the compositing artist uses the matte and foreground to make a composite, a bluish edge may appear in the resulting image. The artist should use the matte and processed (or blue-suppressed) foreground for the best results. Although the Preprocessed Foreground may look noisy in the image widow (depending on the spill replacement mode selected), it will be processed properly and deliver the desired results.

• Foreground shows the original, unkeyed, .

• Background will display the original unadjusted background image.

• Crop Mask shows the black and white Crop Mask based on the current settings in the Crop controls. Black indicates where the composite image will be displayed and the white areas will be cropped.
