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.
¯Note The 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.
