Apple Final Cut Express HD - Manual (Page 890)

890 Part X Real Time and Rendering
Temporarily Disabling Rendering
Normally, Final Cut Express HD attempts to calculate all the effects applied to the frame
at the current playhead position. Sometimes, especially with effects-intensive
sequences, you will want to disable these calculations temporarily while you make
changes to edits in a sequence or to the settings of a motion effect or filter. When
rendering is disabled, all clips that require rendering (indicated by red render bars in
the Timeline) do not appear in the Viewer or Canvas. This way, you can work in the
Timeline or in the Controls, Filters, or Motion tab of the Viewer without waiting for
individual frames at the position of the playhead to render for display. Clips with real-
time effects applied will still appear.
To temporarily disable rendering:
m Press the Caps Lock key.
The Viewer and Canvas both go black. A message appears at the top of both windows
saying “The Caps Lock key is on; rendering is disabled.” Press the Caps Lock key again to
enable rendering.
This message appears in
the Viewer (and Canvas)
when rendering is
disabled.
