How Many Audio Items Does a Nested Sequence Have?
When you nest one sequence inside of another, the nested sequence has only one
video item, regardless of how many video tracks it has in its own Timeline window.
However, the number of audio items that are nested is equal to the number of audio
output channels specified in the Audio Outputs tab of the Sequence Settings window
for the nested sequence.
For example, if sequence A uses a single pair of stereo audio outputs, editing it into
sequence B results in a nested clip with one video and two audio items.
However, if sequence A has six audio outputs assigned in its sequence settings, editing
it into sequence B results in a nested sequence with one video and six audio items. This
is true regardless of how the audio tracks are assigned to audio output channels in the
nested sequence. For example, if you only have two audio tracks in the Timeline of the
nested sequence, and they are assigned to audio output channels 1 and 2, the nested
sequence still has six audio items when edited into another sequence.
Nesting a Sequence Inside Another Sequence
You can edit the contents of a sequence, render it, and then edit that sequence into
another sequence. This section explains the various ways you can nest a sequence into
another sequence.
To nest a sequence that is open in the Viewer:
1 Open the sequence you want to nest in the Viewer by doing one of the following:
 Drag the sequence from the Browser to the Viewer.
 Hold down the Option key, then double-click a sequence in the Browser (this opens
it in its own Viewer window).
 Control-click the sequence, then choose Open in Viewer from the shortcut menu.
2 In the Viewer, set In and Out points for the source sequence.
This lets you nest all or just a part of the sequence.
3 Edit the sequence into another sequence in the Timeline as you would a clip.
To nest a sequence by dragging it into another sequence:
m Drag the sequence from the Browser or Viewer to another sequence in the Timeline, as
you would a clip.
