Creating Simple Linear Speed Effects
If all you need to do is to make a clip play in slow motion, speed it up, reverse the clip, or create
a freeze frame, you can apply a simple speed effect using either the browser or the Change
Speed dialog.
To change a clip’s speed, do one of the following:
Select a clip, choose Clip > Change Clip Speed, and use the controls of the Edit Speed
Change dialog.
Right-click a clip in the Timeline, choose Change Clip Speed, and use the controls of
the Edit Speed Change dialog.
Change Clip Speed operations have the following options:
Change Clip Speed parameters: Changes the speed of the selected clip by whatever
percentage, frame rate, or duration you like.
Ripple Sequence checkbox: If you want the speed change you’re about to make
to ripple the Timeline, pushing or pulling all clips following the current one to
accommodate the clip’s new size, then turn on the checkbox.
Speed effect parameters shown in the Speed dialog
Reverse Speed checkbox: Clicking this box sets the current speed to a negative value,
reversing the motion of the clip.
Freeze Frame checkbox: Changes the entire clip to a freeze frame of whichever frame
is at the current position of the playhead.
Pitch Correction checkbox: Checking this box will perform pitch correction on the
audio attached to the clip so that while the audio duration is changed to match
the picture speed, it will still sound natural. Be aware that pitch correction on large
speed adjustments may not sound as good as pitch corrections made to small
speed adjustments.
Maintain Timing/Stretch to fit radio buttons: Choosing Maintain Timing leaves any
keyframes within the clip locked at their original position, while choosing Stretch
Keyframes results in all Composite, Transform, and Cropping keyframes being
compressed or stretched by the same percentage as the clip during a speed change.
