Optimizing Real-Time Performance for Multiclip Playback
When the Multiclip Playback option is enabled, 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 Volume III, Chapter 28,
“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 Volume III, Chapter 28,
“Using RT Extreme.”
 Disable the Show Source Angle Effects option in the View pop-up menu in
the Viewer.
