6 Select a transition to use this time to switch from CURRENT to NEXT source, such as a slow
dissolve. The CURRENT source (the fighter plane) continues running, and continues to appear
on the output device.
7 To transition to Stonehenge, hold down the SHIFT button and move the T - BAR to the bottom of
its slot, release the SHIFT key, then swing the T - BAR upwards at whatever speed you want the
dissolve to happen.
The
T - BAR and the PLAY button run the same transition, except that the T - BAR lets you manu-
ally control the speed at which the transition runs.

Now that you understand the distinction between the CURRENT and NEXT source, you need to
know how to select sources for each. Use the
CUT and NEXT buttons on the MX-4 DV keyboard to
select sources.
Use the CUT buttons to select the CURRENT source. The four buttons labeled A , B , C , and D corre-
spond directly to the Input Source Previews on the Preview Screen (refer to page 36) and to the
MX-4 DV’s four channels. Use the
BACKGROUND button to select a solid color background rather
than an image coming from a source device (refer to “Using Color Backgrounds” on page 42).
When you press any
CUT button, the output video cuts to the new source and the indicator light
below the CUT button glows steadily.
After selecting the CURRENT source, use the NEXT buttons to select the NEXT source. The but-
tons are labeled the same as the CUT buttons. When you press any NEXT button, the indicator light
above that button flashes.

The VIDEO / AUDIO selector controls which parts of the input signal get used from any given source.
You can set the VIDEO / AUDIO selector to any of three positions — VIDEO only, AUDIO only, or
both. Press the button as required to turn on the Video, Audio, or both lights.
VIDEO – Video changes, audio does not. Video light only is illuminated.
AUDIO – Audio changes, video does not. Audio light only is illuminated.
BOTH – Audio and Video both change. Both the video and audio lights are illuminated.
Many sources (such as pre-recorded video tapes) carry both video and audio signals. Other input
sources (such as a compact disc player) carry only audio signals, and some sources carry only
video signals.
