System information
Locking envelopes to events
From the Options menu, choose Lock Envelopes to Events if you want envelope points and position to
move with an event when it is moved along the timeline.
This button also locks track-level keyframes to the events on the track. When keyframes are locked,
you can move events along the timeline, and their associated keyframes move with them.
Video Track Automation
Video track envelopes allow you to vary compositing levels or fade a track between two colors.
A track envelope will always affect all events on the track. This means that any event envelopes will be
calculated after the track envelope.
To adjust track automation using the controls in the track header, select the Automation Settings button
. When Automation Settings is not selected, the Level slider adjusts static (trim) levels, and the Fade
slider is not displayed.
Choose a fade type from the Video default drop-down list on the Editing tab of the Preferences
dialog to set the default fade type that will be used when you add fade-to-color, composite level, and
event velocity envelopes. This setting is not used for track motion or keyframe envelopes. For more
information, see "Preferences - Editing Tab" on page 601.
