In the New Sequence dialog box, specify the following options:
Sequence Name
Enter a descriptive name for the sequence.
Video
Type the number of video tracks you want the sequence to contain, or click the up and down arrows to change
the number.
Master
Choose an option from the pop-up menu to specify whether you want the Master audio track to be mono,
stereo, or 5.1.
3 For the remaining fields, enter the number of each type of audio track you want the sequence to contain, or click
the up and down arrow buttons to change each number.
4 Click OK to create the sequence.
To learn more about the different types of audio tracks, see “About audio tracks in a sequence” on page 173.
Nesting sequences
You can insert, or nest, sequences into other sequences. A nested sequence appears as a single, linked video/audio
clip, even though its source sequence may contain numerous video and audio tracks.
You can select, move, trim, and apply effects to nested sequences as you would to any other clip. Any changes you
make to the source sequence are reflected in any nested instances created from it. Moreover, you can nest sequences
within sequences—to any depth—to create complex groupings and hierarchies.
The ability to nest sequences enables you to employ a number of time-saving techniques and to create effects that
otherwise would be difficult or impossible. Nesting enables you to do the following:
•
Reuse sequences. When you want to repeat a sequence—particularly a complex one—you can create it once, and
then simply nest it in another sequence as many times as you want.
•
Apply different settings to copies of a sequence. For example, if you want a sequence to play back repeatedly but
with a different effect each time, just apply a different effect to each instance of the nested sequence.
•
Streamline your editing space. Create complex, multilayered sequences separately; then add them to your main
sequence as a single clip. This not only saves you from maintaining numerous tracks in the main sequence, but
also potentially reduces the chances of inadvertently moving clips during editing (and possibly losing sync).
•
Create complex groupings and nested effects. For example, although you can apply only one transition to an edit
point, you can nest sequences and apply a new transition to each nested clip—creating transitions within transi-
tions. Or you can create picture-in-picture effects, in which each picture is a nested sequence, containing its own
series of clips, transitions, and effects.
When nesting sequences, keep in mind the following:
•
You can’t nest a sequence within itself.
•
Actions involving a nested sequence may require additional processing time, because nested sequences can
contain references to many clips, and Adobe Premiere Pro applies the actions to all of its component clips.
•
A nested sequence always represents the current state of its source. Changing the content of the source sequence
is reflected in the content of nested instances. Duration is not directly affected.
•
A nested sequence clip’s initial duration is determined by its source. This includes empty space at the beginning
of the source sequence, but not empty space at the end.
