Three and four point editing are one of the best ways to edit clip on Timeline. Multiple edit points are used to add items on timeline automatically. Media on Source Monitor has two points i.e. In point and the Out point, or the beginning and end if not marked. Similarly Timeline also can have two points. Three and Four point edit uses Insert Edit or Overwrite Edit .
Three Point Edit
Three-point editing uses three total edit points to add items to the timeline. Media on Source Monitor has two points and playhead in the Timeline is the third point. For inserting and/or overwriting clips using 3 – points edit:
- Set the In and Out points on a clip in the source monitor.
- On Program Monitor, position playhead and click Mark Out button to the target Out point. Press the Up and Down Arrow keys to move to an existing edit point.
- Press the Overwrite button
- Marked region of the clip on Source Monitor will overwrite the clip on Timeline. Clip Out point on the Source Monitor overlaps with the with the selected Out point on Timeline. Playback ends at the selected Out point on the Timeline.
If two points are in the timeline instead of the source monitor, then the clip on the source monitor will fill that specific section of the timeline. Single point set in the source will line up with the corresponding point in the timeline. In point set in the source monitor will match with the in point in the timeline. Same holds for out point also.
Below image shows an example of three point edit. Two points are marked on the timeline and In point is marked on source monitor.
Four Point Edit
Four-point editing works the exact same way as that of three point edit. It will have IN and OUT points on both source monitor and timeline. Ideally length of the clip from IN to OUT and the length of the space in the timeline from IN to OUT should will be same. In other words if you have a six second spot to fill in the timeline, select six seconds frames from source clip.
For inserting and/or overwriting clips using 4 – points edit:
- In Timeline or Program Monitor, navigate the playhead to the target In and Out point
- Similarly mark In and Out points on the clip opened in Source Monitor.
- Press the Overwrite button in the Source Monitor.
- In case of duration mismatch between marked point, select the appropriate radio option in Fit Clip dialogue box. Marked region of the clip on Source Monitor will overwrite the clip on Timeline.
Below image shows four points marked points. Two In and Out points are marked, each on source monitor and program monitor.
