Reapplying Normalization Gain
Final Cut Pro searches for peak audio only between a clip’s In and Out points, not for
the entire duration of the clip’s media file. If you trim a clip’s In or Out point, new peaks
may be introduced and the Gain adjustment may no longer be appropriate. In this
case, you can easily reapply normalization gain to set an appropriate level.
Reapplying normalization gain is no different from applying normalization gain for the
first time. The only difference is that no new Gain filters are added to clips that already
have them. Instead, the values of the existing Gain filters are adjusted based on the
current audio peaks of the clips.
