Three-Point-Editing

Recently, I have had the opportunity to learn how and why people use three point editing. Unlike drag editing, three-point editing allows me to use both source clip and sequence in and out points to specify the duration of a source clip and where it should be placed in a sequence. To edit content into a sequence using three-point editing, I set edit points in my source clip and sequence, and then do the edit.

1. Stage 1: Setting Clip In and Out Points in the Viewer
   Specify which part of a source clip wanted to place in the sequence. Do this by opening it in the Viewer and setting the In and Out points.
2. Stage 2: Setting Sequence In and Out Points in the Timeline or Canvas                                       Specify where the clip is to appear in the sequence by setting In and Out points in the Timeline.
3. Stage 3: Specifying Destination Tracks
   Choose the tracks in the Timeline where the video and audio items from the source clip should appear.
4. Stage 4: Adding the Clip to the Timeline
   Edit the clip into the Timeline by dragging it to the Edit Overlay in the Canvas, clicking a Canvas edit button, or using a keyboard shortcut.

Sequence In and Out points always take precedence over source clip In and Out points. If both In and Out points in a sequence are set, the duration of the edit is determined by the In and Out points of the sequence, regardless of the In and Out points of the source clip. This allows me to restrict the portion of the sequence affected by the edit.
