Open a sequence that contains multiclips, then choose Multiclip Playback from the RT
pop-up menu in the Timeline.
Optimizing Real-Time Performance for Multiclip Playback
When the Multiclip Playback option is turned on, Final Cut Pro plays multiple media files
from disk at once. To improve playback performance, you can do the following:
• Use the fastest scratch disk available for your system. The speed of your scratch disk
and the data rate of your media files limit the number of streams you can play back in
real time.
• Reduce real-time playback quality in the Canvas. You can reduce playback quality in
the Canvas to improve multiclip playback performance. You can reduce both video
quality and frame rate. For more information about changing real-time playback settings,
see
“Using RT Extreme.”
Note: Each angle of a multiclip in the Viewer uses the quality selected in the RT pop-up
menu in the Timeline.
• Choose dynamic real-time playback options from the RT pop-up menu. For more
information about changing real-time playback settings, see “Using RT Extreme.”
• Turn off the Show Source Angle Effects option in the View pop-up menu in the Viewer.
Viewing Multiclip Playback on an External Video Monitor
When the Multiclip Playback option is turned on, you can choose whether the Viewer or
the Canvas is displayed on an external video monitor.
To see all multiclip angles displayed on your external video monitor during multiclip
playback
µ
Choose View > Show Multiclip Angles, so that there’s a checkmark next to it.
Note: If no sequence is open, choosing the Show Multiclip Angles option has no effect.
In this case, you always see the Viewer on the external video monitor.
Applying Filters, Speed, and Motion Parameters to Multiclips
Individual angles can have filters, motion settings, and speed adjustments applied.
However, effects cannot be applied globally to a multiclip. For example, you can create
a multiclip in which each angle has an individual Color Corrector filter applied, but the
multiclip itself cannot have a Color Corrector filter applied. The Filters and Motion tabs
of a multiclip display filters and motion parameters for the active angle, not for the entire
multiclip.
Effects can be permanently applied to an angle when you create a multiclip. For example,
if you create a multiclip in which one of the selected clips has a Gaussian Blur filter applied,
that angle in the resulting multiclip will have a Gaussian Blur filter applied.
