How Audio Recorded with the Voice Over Tool
Appears in Your Sequence
Audio is recorded during the pre- and post-roll period each time you use the Voice
Over tool, giving you extra audio for trimming at the head and tail. Each clip has a
5-second handle at the head and a 2-second handle at the end. By definition, handles
do not appear in the sequence clip, but they are visible if you open the clip in the
Viewer. In the Viewer, you’ll see that the In and Out points for that clip match the
beginning and end of the specified recording duration. The extra handles are there
if you need to extend the clip head or tail.
