First, a little definition of a Keyframe: A Keyframe is a conglomeration of several settings
within the VP boards. It consists of size, position, transition frame count, transition mode,
border and crop settings. You can store 10 different keyframes within the Protector, and you can
transition between them. The style of transition can either be a cut or a mix, or be of several
different modes.
Each keyframe must be stored as either a start, stop, continue, loop, or pause keyframe. Forward
transitions always begin with a start keyframe. For a more detailed discussion of the Keyframes
and transition sequencing, see appendix ___ covering processor board function.
In general, for the stock ticker job, you will use only Keyframe 0 and Keyframe 1. Keyframe 0
is preset at the factory to be a full screen, no borders, and no crop, start keyframe, that is set to
transition within 1 frame (or transition in 1/30
th
of a second). Keyframe 1 is factory preset as a
picture-in-picture effect, designed to display compressed foreground video, and reveal the
bottom 1/3 of the background video (the stock ticker). Keyframe 1 is a stop keyframe set at the
same position as Keyframe 0, but the vertical size is adjusted down to 195 lines (as opposed to
242 lines for a full screen display). Keyframe 1 is also set to transition within 1 frame.
The Keyframe screen gives you the ability to change a variety of settings.
The six buttons across the top allow you to manually run transitions between keyframes. You
can use this function to force a transition. Use the Forward and Reverse buttons to transition
between keyframe 0 and 1 (fig. 7).
