To remove scaling or trimming from a clip in
the Motion Mixer, select the clip, right-click
and choose Remove Sc ale/Trim.
To change the speed of an entire clip:
You can cause a motion to slow down or speed up
by changing the length of the clip in the Mixer.
Lengthening a clip w i ll slow down the motion,
while shor tening the clip will speed it up.
1. On the Motion Mixer, click Move Clips.
2. Drag either end of the clip to extend or shorten
it in time.
Tip: To see the ratio of the orig inal motion
time to the new time, click Preferences. In the
Mixer Preferences dialog, turn on Scales. This
displays the r atio on the clip next to its name.
Working with Transitions
Whentwoormoreclipsareplacedonatransition
track (page 3–1027), you can create transitions
between any two clips. A transition creates a
constant, gradual change from one clip to another.
Clips and transitions on Transition track. Transitions are shown
as dark areas between clips.
To learn how to create a transition track, see
Adding Tracks to the Mixer (page 2–607).
If you want to make a less linear blend between
clips than the blend created by a transition, see
Adjusting Track Weight (page 2–619).
Adjusting Transitions
Transitions are automatically created between clips
when you load the clips into a Transition track. You
canadjustthestartorendpointofatransitionby
dragging either end of the transition in the Mixer.
When a transition appears with hatchmarks, this
indicates that the transition is invalid. This can
occur when a clip’s bracke ts are reversed, with
the out-bracket b efore the in-bracket. You can
correct this problem by dragging each end of the
transition to reverse the ends.
A useful transition can occur anyplace where two
clips overlap. The unused part of the clip on either
side of the transition appears with hatchmarks to
indicate that that part of the clip will not be used
in the mix. This type of transition is often used
for foot-based clips, when the best place for a
transitionisnotalwaysattheedgeofaclip.
Hatched parts of the clips are not used in the mix.
The Motion Mixer will allow you to extend a
transition into an area where two clips do not
overlap. However, this transition w ill most likely
