Recapturing and Decomposing
246
If you decompose only some of the clips in a sequence, the resulting sequence contains some
clips that remain linked to existing master clips and media (the clips you did not decompose) and
other clips that are linked to new offline master clips (the clips you did decompose). Once you
recapture media for the new master clips, all the clips in the sequence are available in the formats
you have chosen.
There are several situations in which you might want to decompose some but not all of the clips
in a sequence. For example, you might have made an error while capturing from only one of the
tapes or sources you are using in the sequence. In this case, you can decompose the clips from
just the one tape or source and recapture them. Or you might have a mixed-rate sequence that is
composed mostly of low-resolution clips but that also contains some high-resolution clips. If you
want to up-rez the entire sequence for the online phase of your workflow, you might not need to
recapture the high-resolution material, so you can decompose only the low-resolution parts of
the sequence.
Expert Decompose is particularly useful when you need to recapture some or all of a mixed-rate
sequence because you have complete control over what to decompose and which target formats
to create. You can decompose to several different target formats if necessary, creating new master
clips in the bin. You can then open the bin successively in projects that provide the correct format
for recapturing, select the clips that match each project format, and batch capture those clips.
For information on activating and using Expert Decompose, see “Decomposing Sequences” on
page 247 and “Using Expert Decompose” on page 249.
Target Formats for Expert Decompose
The following table lists the target formats that are available using Expert Decompose. If the
format of an existing clip is listed in the first column, you can decompose the clip to any of the
formats listed in the second column, and then recapture the clip in that format. If the format of an
existing clip is not listed in the first column, then you can only decompose and recapture it in its
existing format.
The third and fourth columns indicate whether or not the format change involves a change to the
source or edit frame rate.
