Apple Final Cut Pro 7 - Manual (Page 1445)

Description Render status Bar color
Indicates a real-time effect that’s capable of
playback and output to video at full quality with
no rendering required. Full Dark green
The media does not need rendering and will play
on the computer screen in real time, but not at
full quality. Preview Green
The effect you see during real-time playback is an
approximation (proxy) of the effect you’ve
specified. Effects indicated by yellow render bars
may ignore some filter parameter controls (for
example, Edge Softness) in order to show you a
real-time preview. To get the true final effect, you
must render these clips. The final effect is
displayed when playback is stopped or when
scrubbing. For example, you may have added a
wipe transition and set the angle to 37 degrees.
Depending on your selected effects quality,
Final Cut Pro may only be able to display the wipe
angle at 45 degrees in real time, so you see an
approximation during realtime playback. You can
still see the effect as you specified it (the 37-degree
angle) by placing the playhead over a frame of
the effect in the Canvas or Timeline, or by
rendering the effect before playing it back. Proxy Yellow
Indicates that an effect has been rendered at a
lower frame rate or quality than currently specified
in the Frame Rate and Resolution pop-up menus
in the Render Control tab of the Sequence Settings
window. These render files are preserved even if
these settings are changed back to 100 percent.
This render status bar color appears when you
render a proxy effect (see the entry above for more
information). Rendered Proxy Dark yellow
Indicates effects that exceed your computer’s
real-time playback capabilities but are enabled
anyway because Unlimited RT is selected in the
RT pop-up menu in the Timeline. Unlimited
real-time playback lets you play more effects but
increases the chances that your sequence will drop
frames during playback. This mode is useful for
getting a real-time preview of complex effects
compositions. Unlimited Orange
The real-time capabilities of Final Cut Pro have
been exceeded and the material must be rendered
before playback or output to tape. Needs Render Red
