Rendering Audio Items in a Sequence
The following commands allow you to render audio items when required for real-time
playback. Audio filters and sample rate conversion are rendered together.
To render individual audio items:
1 Select one or more clips with transitions and filters in the Timeline.
2 Choose Sequence > Render Selection > Audio.
To render all audio items:
1 Select or open a sequence in the Timeline.
2 Choose Sequence > Render All > Audio.
Note: Item render files are preserved even when an item is trimmed shorter, moved, or
copied and pasted, or when either individual audio items or the tracks they’re edited
into are disabled and reenabled.
Using the Mixdown Command
Sometimes, you may have so many audio items edited into a sequence or so many
filters applied that rendering the items in your sequence doesn’t ensure real-time
playback. In this case, use the Mixdown command in the Sequence menu to render all
audio in a sequence prior to playback or output to tape.
To mix down audio in a sequence:
1 Select a sequence in the Timeline.
2 With the Timeline or Canvas active, do one of the following:
 Choose Sequence > Render Only > Mixdown.
 Press Option-Command-R.
A rendered audio file is written to disk so that the sequence can now play back the
render file instead of all the individual audio tracks.
Note: This command has no effect on how your clips are edited. All audio clips remain
on their own tracks in the sequence just as they were before. The Mixdown command
only consolidates the audio for playback in an audio render file.
Once you’ve applied mixdown audio to a sequence, the menu item is dimmed and a
checkmark appears next to it to show that the audio in the sequence has been rendered
as a preview file. If you move any audio clips afterward, the preview file is discarded, and
the Mixdown command again becomes available in the Sequence menu.
