Finding and Marking Long Frames
Long frames are frames with nonstandard frame durations that can occur within a clip
as a result of a problem during capture. You might have long frames in your program for
several reasons. Regardless of why there are long (dropped) frames, you need to know
where they are so you can either prevent them or work around them.
A still image in a movie that’s been made to be deliberately longer than one frame is also
a long frame. Long frames of this type may occur in movies created with one of the many
QuickTime authoring programs. For example, if you use QuickTime Player to insert a still
image with a duration of more than one frame into a movie, that frame is considered a
long frame.
The Mark Long Frames command in the Tools menu identifies long frames within clips
in your program. Each selected clip is scanned, and Final Cut Pro places markers to indicate
the location of any long frames that are detected. Each marker is labeled “Long Frame
N,” where N starts at 1 and increases, depending on how many long frames are present.
If the long frame is the result of a still image in an authored QuickTime movie, that marker
will also include the duration of the long frame.
Important: If you have long frames in your program, it’s important that you find the
problem and solve it. This will prevent further headaches down the line, such as lost
audio/video sync and incorrect timecode. For more information on how to troubleshoot
your system if you experience dropped frames, see
“Problems During Playback.”
