Chapter 3 Basic Operation

3-36Chapter 3 Basic Operation

In chroma keying, a key signal is created based on a specific reference color in the foreground image, and used to replace the corresponding parts of the foreground image by the background image. Normally, the foreground image is created with a plain blue background, which is then replaced by the background image.

Background image

Foreground image

Composite image formed by chroma

keying (program output)

In this system, you can use either of the following methods to carry out chroma keying.

• Auto chroma keying

You point the cursor at part of the background, thus specifying the keying color. This is the quick and easy way to make a composite image.

• Manual chroma keying

You specify the keying color by manual adjustment. This allows you finer control than with auto chroma keying.

By starting with auto chroma keying, then using manual chroma key adjustments as required, you can get the optimum composite image efficiently.

Two-channel chroma keying

With the optional BKDF-711 2nd Channel DME Board installed, you can use a second chroma key channel.

To use two chroma key channels, set both title 1 and title 2 in the TITLE section of the menu control section. To select the foreground image used for the second chroma key channel, press the FRGD 2 button in the delegation section, turning it on, then with one of the AUXILIARY buttons select the desired video signal.

To use a normal effect for a title key

In this case, use one of the buttons in column 1 of the TITLE section to recall the title 1 setting menu (T1LUM, T1CRK, or T1MSK), and make the settings.

To combine the background image and foreground image by auto chroma

keying, use the following procedure.

Basic

Operation

The selected background image appears on the program monitor.

 

2 Select the foreground image with the FOREGROUND bus buttons.

If a preview monitor is connected, the selected foreground image appears in the preview monitor.

3 Select the effect pattern, and press the TITLE button in the effect transition section, turning it on.

Note

Depending on the effect pattern, it may not be possible to use chroma keying. If such a pattern is selected, the TITLE button does not light. Check the “TITLE” column of the table in the section “Effect Pattern Variant Forms and Decorations” ( page A-22), and select a pattern for which this shows a check mark (√).

When the TITLE button lights, the N/R button also automatically lights, indicating that the system is in N/R (normal/reverse) mode. While the TITLE button is lit, it is not possible to switch out of N/R mode.
