If you set a Timeline Out point but no Timeline In point: The incoming source clip
will be backtimed so the Out point of the source clip is aligned with the Timeline Out
point. This can be seen by the thick bar that extends to the left of the Out point in the
Timeline Ruler.
A thick bar indicates a backtimed edit in the absence of a Timeline In point
If you set Timeline In and Out points but only a Source Out point: In this case, the
incoming source clip will also be backtimed so the Out point of the source clip is
aligned with the Timeline Out point, with the Timeline edit points defining the duration
of the source clip being edited.
If you set all four Source In and Out and Timeline In and Out edit points: The Timeline
edit points dictate the duration of source clip that is edited into the Timeline, and the
frame at the Source In point is aligned with the Timeline In point, unless you perform a
Fit to Fill or ripple overwrite edit, both of which can be done as four-point edits.
TIP: If you want to use all four Source and Timeline edit points to retime a
source clip to fit into a specific range of the Timeline, use a Fit to Fill edit
instead of an overwrite edit.
Editing Rules for Split In and Out Points
If you’ve created split In and Out points in the Source Viewer or Timeline, the following
rules apply:
If the Source Viewer has split In and Out Points: The leftmost split point of the
incoming clip, whether video or audio, will be aligned with the playhead when the clip is
edited; the other split point will be offset to the right.
If the Timeline has split In and Out Points: The In point of the incoming clip will be
aligned with the leftmost split point, whether video or audio; the accompanying audio
or video In point will be offset to the split point to the right.
Editing a Specific Range of the Source Clip Into the Timeline
This section provides some common examples of three-point editing when performing edits in
the middle of a previously edited timeline. In the following example, you have a specific range
of source media that you need to edit into the Timeline, and you don’t particularly care what
gets overwritten in the Timeline by the incoming clip.
