Tips for Avoiding Unnecessary Rendering
and Reducing Render Time
Here are some suggestions to avoid rendering:
 Edit the majority of your project using cuts only; add only transitions, effects, or filters
that can play back in real time or that are absolutely necessary in making decisions
about your first cut. Avoiding unnecessary effects and time-consuming rendering can
help you focus on your program’s overall pacing and structure. Once your first cut is
done, you can focus on applying effects like color correction and titles.
 Use the Unlimited RT mode and dynamic real-time playback. For more information,
 If you use effects that need to be rendered, you can get a good idea of how the clip
looks by simply scrubbing through the clip in the Timeline or Canvas to view the
effect one frame at a time.
You can also choose Mark > Play > Every Frame (or press Option-\) to play through a
clip one frame at a time, not in real time, and get a slow-motion preview of how the
effect will look.
 When you change the In and Out points of a clip with filters applied, you may need
to rerender the adjusted areas. To avoid constantly rerendering, you can place a clip
with its applied filters into a sequence and then edit that sequence into other
sequences. This is sometimes called nesting a sequence. Because you modify the
sequence In and Out points instead of the clip within the sequence, the render file
for the clip is maintained. For detailed information about nesting clips using the Nest
Items command, see Volume II, Chapter 23, “Sequence-to-Sequence Editing.”
 Disable filters that require rendering when you don’t need to view the effects in
order to make decisions.
 Disable the rendering and playback of filters, frame blending, and motion blur
individually, or disable these options collectively in the Render Control tab of the
Sequence Settings window. These options can be reenabled at any time.
 Temporarily disable rendering of clips that cannot play back in real time. This allows
you to make changes to effects-intensive sequences without having to wait for
frames at the position of the playhead to render for display in the Viewer or Canvas.
