Panasonic AW-HS50 How-To Chroma Key with the HS50

★

In chroma key, the key signal is created using a specific hue of the key fill signal as a reference.

For instance, the color of the background is sampled (detected) from the image of a person standing in front of a

specific background color so that the key signal is created, and a different background is combined.

As the color of

the background, green or blue is commonly used.

Press KEY-F/S button – (Fig.1-A) to set the crosspoint buttons to key bus selection mode (KEY-F/S button lights up).

* The chroma key functions as the self key, so the key fill signal is used as the key source signal.
