Understanding Keyframes
A keyframe is a point in an effect at which you can set parameters.
When you set parameters to different values in different keyframes, your Avid editing
application animates your effect by calculating intermediate values for parameters between the
keyframes. For example, if a Picture-in-Picture is set to be on the left of the screen at one
keyframe and on the right of the screen at the next keyframe, the Picture-in-Picture moves from
left to right across the screen over the period of time between the two keyframes.
Avid editing applications use two different kinds of keyframes, advanced and standard. In the
current version of your Avid editing application, most effects use advanced keyframes only,
while a small number of effects use standard keyframes only.

In previous versions of Avid editing applications, you could apply some effects as standard
keyframe effects and subsequently choose to promote them to advanced keyframes. This
workflow is no longer necessary or available. Effects either use advanced keyframes only or use
standard keyframes only. For information on promoting existing effects in sequences, or existing
effect templates, see “Updating and Reverting Existing Effects in Sequences” on page 42 and
“Promoting Existing Effect Templates” on page 46.
