Displaying Filter Keyframes in the Timeline
Once a filter has been applied to an audio clip in a sequence, you can use the Clip
Keyframes control in the Timeline to show a keyframe graph area below each audio and
video track in the Timeline to view audio filters that have been applied to your clips.
To view the keyframe graph area:
m
Select the Clip Keyframes control in the lower-left corner of the Timeline.
This area can be divided into three parts for audio tracks in the Timeline.
 Filters bar: If a clip has one or more audio filters applied, a green bar appears in this
space for the duration of that clip. If keyframes are added to a filter in a given clip,
those keyframes appear as diamonds on this bar, where they can be edited or moved
using the Selection tool.
 Keyframe editor: The keyframe editor shows you keyframe graphs for audio filters
applied to clips in your sequence, identical to those found in the keyframe graph
area of the Motion and Filters tabs of the Viewer. You can edit the keyframes of audio
filter parameters in the keyframe editor using the Selection and Pen tools. The
keyframe editor can only display the keyframe graph of one filter parameter at a
time. You can choose the one you want to see by Control-clicking in the keyframe
editor area and choosing an audio filter parameter from the shortcut menu.
