When you apply more effects to a clip than your computer can process in real time, you
need to render temporary media files to play your sequence in real time.
What Is Rendering?
Any time Final Cut Pro must perform more calculations than your computer can handle
in real time, you need to render. Rendering is the process of creating temporary video
and audio render files for segments of your sequence that Final Cut Pro cannot play in
real time. When you render a segment of your sequence, Final Cut Pro substitutes a render
file for the segment during playback. Render status bars above the ruler in the Timeline
indicate which sections can play back in real time and which segments require rendering.
Because rendering takes time away from the editing process, the goal is to render as little
as possible. For more information about real-time playback, see
“Using RT Extreme.”
Rendering is generally required for:
• The use of filters, transitions, generators, or any combination of effects that exceeds
your computer’s real-time playback capabilities
