Default Keyframe

For plugins, there is a special hidden keyframe, called the default keyframe, that is used when no previous keyframe exists. It is like keyframe zero on the timeline, and it is persistent and shared on all sessions. The intent is to make a parameter set that is likely to be reused on all initial instances of the plugin. An example may be to color correct a set of media that was taken in low light, or needs resampling to be played correctly. The default keyframe is off the bar on the left side of the plugin title bar and can not be seen. It is used when there is no previous keyframe for its default values.

It may be useful to create a default keyframe which has specific desirable values for later use. To do this, set the timeline to position 0 and be sure to disable generate keyframes while tweaking. This will create a default keyframe at the beginning of the timeline which contains global parameters for the entire duration. Or if you have copied a non-default keyframe via Keyframes pulldown copy default keyframe, it can be stored as the default keyframe by calling keyframes → paste default keyframe. After using paste default keyframe to convert a non-default keyframe into a default keyframe, you will not see the value of the default keyframe reflected until all the non-default keyframes are removed.

The keyframes → copy default keyframe and
keyframes → paste default keyframe allow conversion of the default key-frame to a non-default keyframe.

Keyframes → copy default keyframe copies the default keyframe to the clipboard, no matter what region of the timeline is selected. The keyframes → paste keyframes function may then be used to paste the clipboard as a non-default keyframe.

Typeless keyframes enabled under the Settings pulldown allow keyframes from any track to be pasted on either audio or video tracks. Ordinarily audio keyframes can only be pasted to another audio track and video keyframes can only be pasted to another video track.
