Chapter 22 Refining Transitions Using the Transition Editor 409

Previewing Transitions Before Rendering Them
If you have to render your transitions, it’s a good idea to preview complex transitions
first. You can preview transitions while you’re modifying them or any time before
rendering them.
To preview a transition, do one of the following:
m Move the playhead in the Canvas, the Timeline, or the Transition Editor over a frame of
the transition.
That frame of your transition is rendered and displayed in the Canvas, on your external
monitor, or both, depending on how your external video settings are configured.
Note: Make sure the Caps Lock key is not engaged. The Caps Lock key
disables rendering.
m Move the playhead in the Canvas or Timeline to a frame just before your transition,
then choose Mark > Play > Every Frame (or press Option-\ or Option-P).
Final Cut Pro plays every frame of your transition, although not in real time.
Rendering Transitions
If you need to render your transitions, you can render all the transitions and effects in
your sequence or only selected transitions. Rendering transitions is just like rendering
clips with filters applied. For detailed information on setting up and using render
quality settings, see Volume III, Chapter 29, “Rendering and Video Processing Settings.”
To render a single transition in your sequence:
1 Select one or more transitions in the Timeline.
2 Choose Sequence > Render Selection > Both (or press Command-R).
To cancel rendering, click Cancel in the status box or press Esc.
To render only transitions and effects that can’t play in real time:
1 Open a sequence in the Timeline.
2 Choose Sequence > Render All, and make sure Needs Render is the only option
enabled in the submenu.
3 Choose Sequence > Render All > Both.
To cancel rendering, click Cancel in the status box or press Esc.
To render all transitions and effects in your sequence:
1 Open a sequence in the Timeline.
2 Choose Sequence > Render All > Both (or press Option-R).
To cancel rendering, click Cancel in the status box or press Esc.
