Working with keyframes
Working with keyframes
A keyframe is a frame at which you’ve defined one or more effect settings to take
place in a clip. The settings start at the frame where you define them, and remain
active on the clip until you define a later keyframe to turn off or change the
settings. This allows you to control the occurrence and duration of your effect
settings. By interpolating between keyframes, you create gradual transitions
between different settings for an effect.
¦NoteThe following sections explain how to use the Matrox realtime plug-in to
work with keyframes. Be aware that the Matrox effects do not support Adobe
Premiere’s keyframes that are applied on the Timeline.
In the following sections, we explain how to:
• Use the effect controls to work with keyframes.
• Perform basic operations such as creating, copying, cutting, and pasting
keyframes.
• Interpolate between keyframes.
Using the keyframes controls
Several controls are provided at the bottom of the Matrox Effect Setup dialog
box to let you work with and view the keyframes in your clip:

Only buttons that can be used at a given time are available. When you hover
your mouse pointer over an available Toolbar button, you’ll see a tooltip
describing the button.
✑ Tracks and Ruler The tracks represent the progression of your clip over
time, with the Ruler above the tracks denoting your clip’s frame numbers.
Keyframes can be created on all tracks except the topmost track. You can
click a track to switch to its corresponding page. For example, clicking the
Transform track displays the Transform page.
✒ Keyframe symbols Whenever you change an effect setting, a symbol
such as appears on the appropriate
track, representing the keyframe
you’ve created. For example, in the preceding illustration, the symbol on
the
Transform track at frame 0 represents a transformation created at the
