Apple Final Cut Pro 6 - Manual (Page 293)

292 Part IV Logging, Capturing, and Importing
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:
Each time a timecode break occurs, Final Cut Pro continues to move the In point later
until there is enough continuous timecode to accommodate the In point in addition to
the duration of the pre-roll. This ensures that you will be able to recapture the clip
again later.
Reset Timecode Breaks
Reset timecode breaks are handled differently. Since a reset timecode break results in
the timecode at the point of the break being reset to 00:00:00:00, the reel name is
incremented along with the clip name. This makes later media management much
easier. The reel number identifies which part of a tape particular group of clips came
from. For example, if a tape with the reel name 004 is captured and a reset timecode
break occurs, the reel name for all clips captured after the timecode break is
incremented with an uppercase letter, in this case 004-B. If another reset timecode
break occurs, the reel number is incremented to 004-C, and so on.
