Which set of points are used in three-point editing?

• A. Source In Point, Source Out Point, and Sequence In Point
• B. Source In Point, Sequence Out Point, Timeline In Point
• C. Mark In, Mark Out, Timeline End
• D. Video In, Audio In, Timeline Start

Answer: (B)

Three-point editing relies on three anchor points to precisely shape both the source portion and where it lands in the timeline. You define an In point on the source to mark where you want to start, a matching Out point on the source to mark where you want to end, and a Timeline In point to specify the exact frame in the sequence where that clip will be placed. With these three references, you can perform an insert edit that brings in the portion from Source In to Source Out starting at the Timeline In point, shifting the rest of the timeline accordingly. That combination—Source In Point, Source Out Point, and Timeline In Point—is what makes three-point editing work. The other options mix in timeline boundaries or marks that don’t provide the same precise three-anchor control over both the source portion and the insertion point.
