Using Speed Settings with Multiclips

You can apply constant speed changes to an entire multiclip (including all its component camera angle clips).

To change the speed of an entire multiclip using the Change Speed dialog

Select the multiclip in the Timeline or the Browser.
Note: If the clip has existing speed settings, they will be replaced by the adjustments you make in the Change Speed dialog.
Choose Modify > Change Speed (or press Command-J).
The Change Speed dialog appears.
Use any of the controls in the Change Speed dialog to create the speed effect you want.
For detailed information on each of the controls, see About the Change Speed Dialogs.
Click OK.

The speed effects are applied to the multiclip. The Change Speed dialog adjusts both the video and any linked audio. Depending on the settings you chose, the clip may be extended or shortened in the Timeline, and those changes may be rippled throughout the sequence.

Working with Multiclips and Speed Effects

Keep the following restrictions in mind when you work with multiclips and speed effects:

Multiclips cannot be created from speed-modified clips.
Multiclips allow constant speed changes only.
When a multiclip is displayed in the Viewer, all angles reflect the speed of the active angle.
A standard switch between angles will remove any speed effects. To retain the speed effect, use the Switch Video with Effect command.

You cannot apply variable speed effects (speed segments) to an entire multiclip, nor to any of its component camera angle clips. However, you can export a clip with variable speed effects and then import that file and add it to a multiclip.

To include a camera angle clip with a variable speed effect

Apply a variable speed effect to a clip.
Export the clip as a QuickTime movie.
Import the clip.
Add the imported clip to the multiclip.
