Which editing function uses the position of the source and playheads?

• A. Ripple
• B. Replace
• C. Slip
• D. Lift

Answer: (B)

A Replace edit is about swapping the media in the timeline using two precise reference points: the frame you’ve set in the source viewer (the source playhead) and the exact location in the timeline (the timeline playhead). You position the source playhead at the frame you want to insert, then perform the replacement at the timeline’s playhead location, effectively pulling that exact frame from the source into that spot in the sequence. That dual reference is what distinguishes it here. The other edits work differently: a ripple edit uses the timeline location to push or pull adjacent content as the duration changes, a slip shifts the framing by moving inside the clip’s own source frames, and a lift trims material at the edit point without pulling in a new frame from the source.
