the metadata for.
Note: You cannot edit the metadata of a clip if it is locked.
2.
Click Clip Library > Modify... .
3. Click on the Trim tab.

In the
Trim In
field, enter the new starting timecode
value for the clip. The Record Start field shows
the timecode at the start of the clip.
5. In the Trim Out field, enter the new ending
timecode value for the clip. The
Recording End
field shows the timecode at the end of the clip.

Use the Advance fields to slip the video, audio, or
timecode track back in relation to the other tracks
in the clip. Only those tracks that are present in the
clip are shown.

particular track back half of a field/frame.

Parent/Child Clips
You can create virtual copies of a clip. These child clips
are essentially pointers to the parent clip that use an
independent set of metadata. This allows you to create a
number of child clips that are trimmed differently from
their parent and each other without taking up additional
space on the media drive.
Once a child clip has been created, you cannot delete the
parent clip until all the child clips have been deleted.
To Create a Child Clip
The child clip can have different metadata from the parent
clip.
Note: You cannot create a child clip if the parent clip is locked.
You must first unlock the parent clip before you can create the
child clip.
1. Right-click on the clip that you want to create a child
of.
2.
Click
Create Child Clip
.
The child clip appears in the clip list with the same name
as the parent clip with
- Child
appended to the end
of the clip name.

granted permission to delete multiple clips at once.
Note: Only Administrator and Privileged accounts can delete
clips from the server.
To Delete a Clip
