✒ Effect List This section provides a small sample (icon) representing each
effect. Simply click an effect to select it. If you’re creating a transition, “A”
and “B” represent your clips on the Video 1A and 1B tracks, respectively. If
you’re creating a video effect, “A” represents the clip on which you’re
applying the effect, and “B” represents your underlying (background) image
on the lower tracks.
 Preview Window Allows you to see the result of your chosen effect. Your
effect will also be displayed on your NTSC or PAL video monitor.
✔ Effect modifiers By selecting Allow changes, you can change various
settings for the effect (these will differ for certain transitions and video
effects). These settings are active for the duration of your clip. Not all
Matrox effects have effect modifiers on the pre-created page.
✕ Keyframe controls Several controls are provided in this section to let you
move around to different points on your clip and create keyframes. For
details, see “Working with keyframes” on page 157.
$ Tool ba r Provides buttons for the most commonly used keyframe tasks.
Only buttons that can be used at a given time are available.
$ Tracks and Ruler The tracks represent the progression of your effect over
time, with the Ruler above the tracks denoting your effect’s frame numbers.
You can create keyframes on the tracks to change a clip’s settings over time,
such as to make a clip progressively shrink and expand.
$ Positioner You use the Positioner (vertical bar) to preview an effect by
dragging it across the Ruler (scrubbing), or to specify at which frame you
want to create a keyframe on the track. To move the Positioner to a particular
frame, enter the frame number in the
Current frame box, or click the frame
on the Ruler. You can also right-click the Positioner or Ruler to display a
pop-up menu with commands for moving the Positioner.
