1 Transition Effect Buttons
You can assign transition effects to buttons 1 through 3. By default, the following three types are assigned.
1 MIX The A and B pictures change gradually.
2 WIPE The A and B pictures change using a wipe.
3 EFX The A and B pictures change using a soft wipe.
2 Video Fader
This has the following three applications.
A/B switching
When no compositing effect is being applied, moving the fader forward or backward switches the video
between A-bus and B-bus.
Adjustment of the amount of keying When you are carrying out chroma or luminance key composition, this adjusts the degree of extraction.
Inset screen display-level adjustment When you are carrying out Picture-in-Picture composition, this adjusts the display level of the inset screen.
By default, the video fader is installed vertically (operating front to back), but you can reinstall it horizontally (operating side to side). Refer to
“Changing the Installed Orientation of the Video Fader” (p. 57).
3 BPM SYNC Button
You can make A/B switching or turning effects on/off to occur in sync with the BPM (beats per minute). Pressing this button to
make it light up enables the automatic switching (p. 29).
