When you create a merged clip from two or more clips, it becomes a new master clip,
with no affiliation to the clips from which it was created. For more information on
master-affiliate clip relationships, see
“Working with Master and Affiliate Clips.”
Use Accurately Captured Media to Create Merged Clips
It’s always important to make sure that the timecode captured with your video and audio
media is accurate before creating merged clips.
When capturing audio for use in a merged clip, make sure that your audio deck is
synchronized to the same video timing signal used when capturing video. A blackburst
generator (also referred to as house sync) can be used to supply both video and audio
interfaces with a common timing signal. For more information, see
Professional Video and Audio Equipment.”
Using Synchronization Points to Create Merged Clips
Before actually merging clips, you need to find a synchronization point between them.
There are different ways of doing this, depending on how you shot your footage:
• If the timecode of your video and audio clips isn’t identical, and you slated all your shots at
the beginning with a clapboard: You can use In points to line up all the clips you want
to merge.
• If the timecode of your video and audio clips isn’t identical, and you have one or more shots
that you tail-slated at the end: You can use Out points to line up all the clips you want
to merge.
• If the timecode of the video and audio recorders used on the shoot was synchronized: You
can use the timecode of both the video and audio clips to synchronize them.
If you have a complicated combination of syncing In and Out points, and your video and
audio clips don’t have matching, synchronized timecode, you can add auxiliary timecode
to each clip so that the clips’ sync points all fall on the same timecode number. You can
then use the auxiliary timecode track (Aux TC 1 or 2) to merge your clips. This is just like
using the main timecode track for syncing, but auxiliary timecode tracks are useful because
you keep the original timecode track intact, which is critical for recapturing your media
from the original source tapes. For more information about adding auxiliary timecode to
a clip and its media file, see
“Modifying Timecode in Media Files.”
