Which editing operation inserts material into the timeline at the current position and can disrupt alignment between tracks?

• A. Splice-In
• B. Extract
• C. Lift
• D. Ripple Edit

Answer: (A)

Inserting material at the current position means placing a new clip exactly where the playhead sits, and everything that follows on the timeline is shifted to make room. This pushes all subsequent media to the right, which can disrupt synchronization between tracks because the in-points and out-points that were previously aligned no longer line up after the insertion. The other edits do different things: extracting removes material and closes the gap, so the timeline remains continuous and alignment is preserved. lifting removes material but leaves a blank space on that track, creating a gap that can cause misalignment unless you fill it. Ripple editing adjusts the edit point and propagates changes forward, effectively moving later material to accommodate the edit without adding new content, so it alters timing but isn’t inserting new material.
