Editing in the Timeline Vs. Source Monitor

You can select the portions of the film you want to use in one of two ways.

Source Monitor:

From the source monitor, you can make In points and Out points and then perform an insert edit or an overlay edit to the timeline (see Insert Vs. Overlay for the difference). If you do not mark an In or Out point, you will be using the entire clip. Remember that this edit will occur wherever the CTI (current time indicator) is in the timeline.

Timeline:

If you prefer to work directly in the timeline as if it were a canvass and you are a painter, the cursor (mouse cursor) will be your best friend. The cursor changes offering different options dependent on what part of the clip it is hovering over.

There are four key concepts you need to be mindful of when editing (especially timeline editing):

• Trim - trimming establishes the In and Out points of a clip in the timeline
• Ripple - has two functions. With ripple you can create space for a new piece of footage you wish to insert of you remove space created by lifting (see below) or hitting the delete key.
• Lift - removes footage from the timeline but preserves that space that was allotted to it.
• Extract - removes footage from the timeline and ripple deletes the space that was allotted to it so that adjacent clips are butted up against each other.
  

Three Point Editing:

A popular term in the professional editing industry is ?three point editing?. This simply means that you have a marked portion of your source material that you intend to insert or overlay edit at a specific and marked point in your Program Monitor. For three point editing, both the Source Monitor and Program Monitor windows are utilized.
