493. Basic operations3-4-1. Selecting the key typePress the [KEY] button to light its indicator, and display the KEY menu. Refer to “2-1-5. LCD menu area”.Turn [F1] to display the KEY sub menu.Turn [F2] to select the Type item.KEY 1|Type |LumKey |Fill |PVWKEY | Linear|ChrmOff| Bus| AutoLumChromaFullChrmOn Matte OffOnLum (luminance key/self key):This is for creating the key signals from the luminance component or luminance and chromacomponent of the key fill signal.Linear (linear key/EXT key):This is for creating the key signals from the luminance component of the key source signal.It is used when the key source signal and key fill signal are different.Chroma (chroma key/self key):This is for creating the key signals using a specific hue of the key fill signal as the reference.Full (full key/self key):This is for creating the key signals using the images on the full screen as the key source signals.PinP combinations are possible in conjunction with the flying key.  See “3-4-9. Flying key”.Since the luminance and chroma keys are operated as self keys, the key fill signals are used as the keysource signals. For the full key, the images on the full screen are used as the key source signals.When the luminance key, chroma key or full key has been selected as the key type, the key signals willremain unchanged even when the key source signals are switched.When using the linear key, use material with a black background and white characters or shape to becombined by the key as the key source signal. Material which is not black and white may not be combinedclearly.Material with a white background and black characters, etc. can be reversed using the key invert function foruse.When the luminance key has been selected, the chroma component can be included in the generation of thekey signals in view of the self key application. (This does not apply to the linear key.)Turn [F3], and select the setting using the LumKey item.ChrmOn: In addition to the luminance component, the chroma component is also taken into account inthe generation of the key signals.This is the setting for using a colour with a low luminance component for the key signals (suchas when defining blue characters).ChrmOff: The key signals are generated from only the luminance component.Turn [F4] to select the fill type using the Fill item.Bus: The bus signal is used for the key fill signal.Matte: The internal fill matte is used for the key fill signal.
