 Mark Long Frames: The frame rate of a media file determines the duration of each
frame. Long frames are frames that have a longer duration than expected based on a
media file’s frame rate, and they are often the result of a problem during capture. The
Mark Long Frames command analyzes one or more clips in the Browser or Viewer,
and places markers to indicate any long frames that are detected. You may use this
command if you have any doubt about the integrity of your clips’ media files. You
can clear long frame markers later using the Clear Long Frame Markers command.

Finding and Marking Long Frames
 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 “
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.
