Apple Final Cut Pro 7 - Manual (Page 320)

• Warn After Capture: If this option is selected, timecode breaks are reported after capture
and the media file with the timecode break is preserved. It is unwise to use such a clip
unless you have no choice, because timecode breaks result in incorrect timecode from
the timecode break forward, and will make it difficult to accurately recapture your
media.
Using the Make New Clip Option
When you choose Make New Clip from the “On timecode break” pop-up menu in the
User Preferences window, ordered and reset timecode breaks and timecode gaps are
handled in different ways. The pre-roll and post-roll values in the current device control
preset also affect how the In and Out points of the resulting clips are determined.
Ordered Timecode Breaks
When an ordered timecode break occurs, the video that’s already been captured is saved
in the logging bin in the Browser as a single clip, with its Out point at the frame occurring
immediately prior to the discontinuous timecode. Final Cut Pro then continues to capture
video after the timecode break to a second media file.
The In point of this second media file is calculated by adding the pre-roll duration to the
frame occurring immediately after the dropped timecode frame. The pre-roll duration is
taken into account so that if you ever try to recapture the clip, there is enough acceptable
video footage before the In point to allow for VTR pre-roll.
Clips captured after timecode breaks are named by combining the original name and
the number of the clip. For example, if the first captured clip’s name is “Cats Playing,” the
second clip’s name is set to “Cats Playing-1,” then “Cats Playing-2,” and so on.

Cats Playing-1 clip Cats Playing clip

If a timecode break occurs during the pre-roll period (before the clip’s specified In point),
Final Cut Pro moves the In point later to accommodate the currently specified pre-roll
duration from the timecode break point to the new In point. For example, when a timecode
break occurs within the default pre-roll duration of 3 seconds, the In point is moved later:
