About the Keyframe Graph Area
This area can be divided into four parts relating to motion, filter, and speed parameter
settings applied to your clips.
 Filters bar: If a clip has one or more video or 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 green diamonds on this bar, where they can
be edited or moved using the Selection tool.
 Motion bar: If any of a clip’s motion parameters are modified, a blue bar appears in
this space for the duration of that clip. If keyframes are added to the motion settings
for a given clip, those keyframes appear as blue diamonds on this bar, where they
can be edited or moved using the Selection tool. Motion bars are available only for
video tracks.

 Keyframe editor: For clips with applied effects, the keyframe editor shows you motion
or filter parameters’ keyframe graph lines and keyframes. These keyframe graph lines
are identical to those found in the keyframe graph area of the Motion and Filters tabs
in the Viewer. You can edit keyframes in the keyframe editor using the Selection and
Pen tools. The keyframe editor can display the keyframe graph lines of only one
parameter at a time.
Keyframe graph lines displayed in the keyframe editor are color-coded: motion
parameter graph lines are blue (matching the color of the blue motion bar), filter
parameter graph lines are green (matching the color of the green filters bar), audio
level overlays are pink, and pan overlays are purple.
 Speed indicator area: Speed indicators show you the speed of clips in your sequence
using tick marks. The spacing and color of these tick marks indicate the speed and
playback direction of your clips. The speed indicators of clips in the Timeline update
as you make variable speed adjustments to clips in your sequence, showing you
exactly how you’re altering a clip’s timing. There are no user-adjustable controls in
the speed indicator area. However, you can display time remapping keyframes on the
motion bar in the keyframe editor to make variable speed adjustments.
For more information about viewing speed indicators while making speed changes
to clips in a sequence, see “
