1. Basic operations

1-3. Key

This operation combines the background image with another image. The key definition can be adjusted, and an edge can be added to the combined image.

Also available as materials besides KEY for combining with the background image are PinP (picture in picture) and DSK (downstream key).

The default settings for priority (image positioning) are as shown in the figure below.

The priority for Key, PinP1 and PinP2 can be changed.

Refer to “1-3-10. Setting the priority”.

How key combinations work is shown in the figure below.

1-3-1. Selectingk the key type

1 Press the button to light its indicator, and display the Key menu.

2Use [F1] to display the Key sub menu.

3Use [F2] to select the Type item.

Lum

This is for creating the key signals from

(luminance key/

the luminance component or luminance

self key)

and chroma component of the key fill

 

signal.

Linear

This is for creating the key signals from

(linear key/

the luminance component of the key

EXT key)

source signal.

 

It is used when the key source signal and

 

key fill signal are different.

Chroma

This is for creating the key signals using

(chroma key/

a specific hue of the key fill signal as the

self key)

reference.

Full

This is for creating the key signals using

(full key/self key)

the images on the full screen as the key

 

source signals.

 

PinP combinations are possible in

 

conjunction with the flying key.

 

See “1-3-9. Flying key”.

Since the luminance and chroma keys are operated as self keys, the key fill signals are used as the key source 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 will remain 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 be combined by the key as the key source signal. Material which is not black and white may not be combined clearly.

Material with a white background and black characters, etc. can be reversed using the key invert function for use.
