The edge fill may be either the signal from the dedicated color matte generator, or the signal currently selected on the utility 1 bus. In the case of an outline, there is no edge fill signal selection, because the key fill signal fills the outline, and the rest of the image remains as the background. For the emboss effect, in place of the edge fill signal, the emboss fill matte 1 and emboss fill matte 2 signals are used. Mask A mask uses the background or a key to hide a part of the image. You can correct the image, such as unwanted holes that appear in the background or when a key is not the desired shape, using masks. Key mask and background mask There are two types of mask: a key mask and a background mask. Key mask: This masks out a part of the key so that the background becomes visible. Background mask: This masks out a part of the background so that the key fill becomes visible. Key mask Masked area (box) Background mask Main mask and sub mask Each keyer allows two masks to be used simultaneously, and these are referred to as the main mask and the sub mask. The signal that determines the mask shape and size is termed the mask source, and different sources are used for the main mask and sub mask. Main mask: This uses the signal from the box generator provided on each keyer or the signal from a dedicated pattern generator as the mask source. When the box generator is selected, a mask using a rectangular signal is formed. When a pattern generator is selected, you can select the pattern and apply modifiers. Sub mask: This uses the wipe generator signal or the signal selected on the utility 1 bus as the mask source. When the wipe generator is selected, the patterns and the pattern modifiers are the same as for a wipe transition. Key Memory The key memory function allows the keyer settings on each cross-point button to be automatically stored, so that the next time the same cross-point button is selected these settings are recalled automatically. There are two modes for key memory: simple mode and full mode. The parameters stored in each mode are as follows. Simple mode: key type, clean mode (including the plane setting for chroma keying), key position, key invert, and adjustment values for the particular key type (Clip, Gain, Density, Filter, etc. This includes color vector key, wipe pattern key, key wipe pattern key, and chroma key. However, in the case of a chroma key, it excludes color cancel, Y balance, foreground CCR, window, and shadow.) Full mode: All settings except transitions (the same parameters as simple mode: Fine Key, key modifiers, main and sub mask settings, chroma key detailed settings, and so on) For details about setting the mode, see "Selecting the key memory mode" (page 468). Key Defaults With a simple operation, you can return the key adjustment values to their defaults. The adjustment values which can be returned to their default values are as follows. • Adjustment values for the particular key type (Clip, Gain, Density, Filter, etc.) In the case of chroma keys, all adjustment values return to their default values. • Key position • Key invert • Clean mode For details, see "Returning the key adjustment values to their defaults" (page 129). 109
