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.

    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.

    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.
