Basic Editing
U N D E R S TAN D I N G TH R E E -P OI NT E D ITI N G
As you’ve probably noticed, you have the ability to selectively mark IN and OUT points in both
your source material and in the Timeline with a variety of results depending on your choices. Here
is a brief primer on the fundamental principles of three-point editing and some other variations in
placing IN and OUT marks:
1. Define the starting and ending points of the source clip. With this technique, mark an IN and
OUT in the source clip, and mark an IN or OUT (but not both) in the Timeline. You can use this
method to either splice or overwrite.
2. Define a specific duration in the Timeline. Mark an IN and OUT in the Timeline, and mark an
IN or OUT (but not both) in the clip. With this technique, you would typically use the Overwrite
tool to replace the content marked out in the Timeline.
Here are some other ways to mark clips and the resulting edits:
OUT marks only: When you use only an OUT mark (no IN mark) in the source clip or the
Timeline, the system uses the process of backtiming to automatically determine the starting point.
For example, you might have a specific frame at which you want a source clip to end while replac-
ing a shot in the sequence. In this case, you mark that frame as the OUT point in the source and
then define the region you want to replace in the Timeline with IN and OUT marks. The system
will automatically determine the start frame of the source clip.
No marks: If you don’t add IN and OUT marks to the source clip or the Timeline, the system will
use the portion of the source clip extending from the blue position indicator to the end of the clip
and either insert or overwrite at the location of the position indicator in the Timeline.
IN marks only: If you apply IN marks in both the source clip and the Timeline, the system will
use the portion of the source clip extending from the IN mark to the end of the clip and either
insert or overwrite at the location of the Mark IN in the Timeline.
Four marks: If you apply IN and OUT marks to both the source clip and the Timeline, the OUT
mark in the Timeline takes precedence, and the source clip OUT mark will be ignored.
Snapping to an Edit Point in the Timeline

tail of a shot in the Timeline, when you’re performing a splice or an overwrite
or when dragging segments from the Source monitor to the Timeline. One of
the best and quickest methods to do this is to snap to a transition point so
you will never have to worry if you’re even one frame off. (This technique is
not track sensitive, so you don’t have to select a track to perform it).
