Using Chroma-Key to Combine Images

For each bus, you can use up to four effects simultaneously. However, there are some combinations of effects that cannot

be used simultaneously. For details, refer to “Effects that Cannot Be Used Simultaneously” (p. 107).

For details on specifying the key color and edge level, refer to “Detailed settings for key-compositing effects” (p. 47).

You can change the effect that is assigned to the [2 (CHROMA KEY)] button. For details, refer to “Assigning Different

Effects to the EFFECTS Buttons” (p. 53).

When using chroma-key to composite the images of bus A and bus B as described above, you can’t use the bus A

[CONTROL] fader to fade out (p. 31) the bus A image.
