Duration of Merged Clips
The beginning, end, and overall duration of a merged clip depend on the method you 
used to synchronize the original clips:
 If you synchronized all of the original clips using In points, the beginning of the
resulting merged clip corresponds to the In point you used, and all clips line up at 
that point. The end of this merged clip corresponds to the end of the clip with the 
latest timecode value.

 If you synchronized all of the original clips using Out points, the end of the resulting
merged clip corresponds to the Out point you used, and all clips line up at that point. 
The beginning of this merged clip corresponds to the beginning of the clip with the 
earliest timecode value.
 If you synchronized all of the original clips using timecode, the beginning of the
resulting merged clip corresponds to the beginning of the clip with the earliest 
timecode value, and the end of the resulting merged clip corresponds to the end of 
the clip with the latest timecode value.
Gaps appear in a particular track if one or more items in a merged clip is shorter than 
all the others, but they cause no problems.
