Pros and Cons of Nested Sequences
Before you start using nested sequences in your project, it’s important to understand
some of the advantages and disadvantages of working with them.
Pros
 Nesting allows you to reuse an entire sequence of clips over and over. You can
change a nested sequence and the changes are reflected everywhere.
Cons
 Multiple levels of sequence nesting can take a while to display, since they require
additional processing.
 If you are exporting an EDL, nested sequences may generate confusing timecode
numbers and reel names.
 If you are exporting an OMF file, nested sequences will be mixed together and
exported as a single audio media file.
 Nested sequences make media management more complicated.
If you decide you don’t want to nest a sequence, you can still edit content from one
sequence to another. For more information, see “

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.
