BASIC TRANSITION CONCEPTS

Transitions create on-screen effects used when switching from one source to another (that is, one scene to another). The most basic type of transition is the cut, where the first frame from the NEXT source immediately replaces the last frame from the CURRENT source. Cuts produce abrupt changes. Other types of transitions use special effects to produce a smoother, more artistic change from one source to the next. The following illustration shows a horizontal wipe transition.

NOTE

When discussing transitions, we use the letters a and b to differentiate the beginning scene (a) from the ending scene (b). These letters often appear in the transition icons to indicate the direction in which the transition travels. These letter indicators have no relationship to the A, B, C, and D letters used to differentiate between the MX-4 DV channels.

The following basic steps explain how to run a transition with the MX-4 DV. Each step is described in more detail later in this chapter.

To run a transition:

1Display the CURRENT source on the output screen. For example, press CUT/A to make A the current source.

2Select the NEXT source — the one you want to appear on the output following the transition. For example, press NEXT/B to make that the next source.

Highlights above and below the source previews indicate CURRENT and NEXT sources, respectively.

3Select a transition to use. For example, press the BASIC Transition Category button, then select a wipe transition from the menu.

4Prepare the sources (such as VCRs and camcorders) and let them roll.

5At the right moment, use either the T-BARor the PLAY button to run the transition.

As you can see, you first set up the transition, then execute it. Nothing happens until you use the T-BARor PLAY button to run the transition. So, you set everything up, then run the transition at the precise moment you want it to occur. As soon as one transition finishes, immediately set up the next one so that all you have to do is press PLAY or use the T-BARto proceed.
