Using Sync Point Editing
Sync Point Editing (SPE) allows you to overwrite material onto your
sequence in such a way that a particular point in the source material is
in sync with a particular point in the sequence. For example, you can
sync an action in the source video with an audio event, such as a musi-
cal beat in the Record monitor, then edit it so that the action occurs on
the beat.
Like a replace edit, Sync Point Editing uses the relative location of the
position indicator in both the source and record material as the sync
point. However, Sync Point Editing determines the duration of the
new edit according to marks that you set, as opposed to a replace edit,
which uses the head-to-tail frame duration already established in the
Timeline. You can apply these marks across multiple tracks when
marking a sequence. This allows you to add overlap cuts.
SPE requires two pieces of information:
• The sync points: These are the points where the synchronized
relationship between the source and record material is established.
• The duration of the relationship: This is determined by the posi-
tions of the head and tail frames (and sometimes by the position
indicator). Both marks can be in one monitor, or one mark can be
in one monitor and the other mark in the other monitor. The dura-
tion of the material being edited into the sequence must be suffi-
cient for the size of the edit.
To perform a sync-point edit:
1. Load a clip or sequence into the Source monitor.
2. Load a sequence into the Record monitor.
3. Mark the material in one of the following ways:
• Mark the IN and OUT points in either the Source or Record
monitor, leaving the opposite monitor clear of marks.
