The Rules of Three-Point Editing
In the previous examples, three-point editing was being used by virtue of source In and Out
points being set to define a range of the source clip to be edited into the Timeline, and the
Timeline playhead being used as the acting Timeline In point; three points defined the edit to
be made. However, three-point editing is also very useful when you need to overwrite sections
of a previously edited timeline with new source clips in a controlled manner, such as when
adding an insert shot to a scene to cover a particular change you’re making that would
breakcontinuity.
Depending on the combination of Source and Timeline In and Out points you set, the following
rules govern three-point editing:
If there is no In point in the source clip: The first frame of media will be used as the
acting source In point. This can be seen by the thick bar that extends to the left of the
Out point in the Source Viewer’s jog bar.
A thick bar indicates which part of the source clip will be used in the absence of a Source In point
If there is no Out point in the source clip: The last frame of media will used as the
acting source Out point. This can be seen by the thick bar that extends to the right of
the In point in the Source Viewer’s jog bar.
A thick bar indicates which part of the source clip will be used in the absence of a Source Out point
If there are no In or Out points in the Timeline: The playhead will be used as the
acting Timeline In point.
If you set a Timeline In point but no Timeline Out point: The whole range from the In
to Out points of the source clip is edited into the Timeline such that the Source In point
is aligned with the Timeline In point. This can be seen by the thick bar that extends to
the right of the In point in the Timeline Ruler.
A thick bar indicates where the Source clip will be edited in the absence of a Timeline Out point
