Selectively Rendering Parts of a Sequence
There are several ways to selectively render specific parts of your sequences.
 Select the items you want to render manually: The easiest way to control what is
rendered is to select the sequences or clips you want to render using the Selection
tool. For example, you can select any number of sequences in the Browser, and then
render them all at once by choosing Sequence > Render All > Both.
You can also select clips in an open sequence, individually or in groups, and render
only those clips by choosing a command in the Render Selection submenu. You can
select items in the Timeline to render with the Selection tool, or the Group Selection
tool, or by setting In and Out points in the Timeline. This is a good way to save time
by isolating a section of a sequence you’re working on for rendering. For more
information on selecting items in the Timeline, see “
 Render audio and video clip items separately: Since audio clip items in a sequence with
audio filters applied are rendered on a per-item basis, you can choose to render only
the audio effects in your sequence to free up processing resources to enable real-
time mixing across more audio tracks, or for real-time video effects that would
otherwise require rendering.
Note: For more information about item-level rendering for audio clips, see “
 Render items according to their Timeline playback state: Final Cut Express HD has
several render categories (or Timeline playback states), indicated by the color of the
render status bar above the ruler in the Timeline. You can specifically choose which
categories to render.
For example, while you’re editing, you may only want to render clips with effects that
can’t play back in real time. In this case, you can select the option to render sections
with the “Needs Render” status in the Render, Render All, or Render Only submenus
of the Sequence menu. This limits the scope of the Render command to clips that
can’t play in real time, while clips with real-time effects applied are not rendered.
Later, when you need to output your project to tape, you can select additional
render categories to render using the Render All command. This allows you to render
all items with effects at the highest quality, prior to output.
Note: Final Cut Express HD automatically renders all effects that cannot be played
back at full quality in real time prior to output using the Print to Video command.
