Using Luminance-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).
• To adjust the luminance level or edge level, refer to “Detailed settings for key-compositing effects” (p. 47).
• You can change the effect that is assigned to the [3 (LUMINANCE KEY)] button. For details, refer to “Assigning Different
Effects to the EFFECTS Buttons” (p. 53).
