Recapturing and Decomposing
245
Consider creating a duplicate of the original version of your sequence before recapturing. You
might also want to create a new bin to store the duplicate sequence and keep the new master clips
created by the recapture or decompose operations separate from existing clips. For example,
duplicate a sequence that uses low-resolution clips to save storage space if you want to recapture
the sequence at a higher resolution while retaining the low-resolution version.

If you use decompose, you can choose to create a duplicate sequence automatically in the
Decompose dialog box. However, if you want to organize new master clips in a separate bin, you
need to duplicate the sequence and place it in a new bin before you start the decompose process.
Understanding Decompose and Expert Decompose
Decompose creates new master clips in the bin based on the lengths of the clips edited into a
sequence. You can then recapture media for the new master clips. Decompose breaks any links to
the original source clips, and only the sequence and its new master clips are linked to the newly
captured media files. If decomposing results in a change to the edit rate of some clips in the
sequence, your Avid editing application adds Motion Adapter effects, or modifies existing
Motion Adapter effects, to manage the edit rate change.
Decompose gives you more control over the recapturing process than simply recapturing a
sequence without using decompose. You can sort or modify the clips that decompose creates
before you recapture media. You can also use the Expert Decompose feature to customize how
decompose operates.
For film projects, clips you create with decompose retain all the information from the original
master clips, including Pullin column information, key numbers, ink numbers, or any other
information formerly entered in the bin.

You do not need to decompose clips that were linked with the AMA (Avid Media Access) method.
For information about AMA, see “Acquisition of File-Based Media (AMA)” on page 374.
Expert Decompose
Expert Decompose lets you control the following aspects of the decompose process:
• You can select which material in the sequence to decompose, either by tape/source or by
clip.
• For tapes/sources or clips that you can recapture in several different formats, you can select
the target format to which you want to recapture.
For information on the available formats, see “Target Formats for Expert Decompose” on
page 246.
