Apple Final Cut Pro 6 - Manual (Page 1605)

122 Part I Media and Project Management
 Mark Audio Peaks: Clipping occurs in captured audio if any part of the recorded
signal goes above 0 dBFS. Since 0 dBFS is the maximum digital level possible, all
levels that would peak above this are set (clipped) to 0 dBFS, because there is no
higher value possible. Excessive 0 dBFS peaks usually indicate that the audio was
recorded at unsuitable levels. The Mark Audio Peaks command analyzes one or more
clips and places markers to indicate 0 dBFS peaks that are detected. You can clear
audio peak markers later using the Clear Peak Marks command. See Volume III,
Chapter 3, “Evaluating Levels with Audio Meters.”.
About the Analyze Movie Command
The Analyze Movie command is an extremely useful tool. With it, you can:
 Troubleshoot your media files: You can check the properties of your clips’ media files,
including the frame rate and data rate, and check whether the media files have any
dropped frames.
 Find the parameters of QuickTime media files: Editing is much easier when the media
file settings match the sequence settings. When you have a media file whose settings
you don’t know, you can use the Analyze Movie command to determine the media
files’ settings, and therefore what sequence settings you need to edit with that
media file into a sequence in Final Cut Pro. You can even create a sequence preset
to match these parameters to use for editing the clips.
Using the Analyze Movie Command
The Analyze Movie command displays track and media properties of a QuickTime
media file in a Movie Analysis window. For details, see the next section, “
Information
Reported by the Analyze Movie Command .” The contents of this window can’t be
printed from Final Cut Pro, but you can copy and paste the contents into any
text-based application, such as a word processor or SimpleText.
