What type of edit is created when dragging clips without using the Ctrl modifier key?

The correct choice, which refers to an overwrite edit, occurs when clips are dragged and placed over existing footage without holding down the Ctrl modifier key. This action replaces the current content in the timeline with the new clip being dragged, effectively overwriting the previous footage. This is a common editing technique used to quickly swap out clips while maintaining the timeline's overall structure, particularly when precise timing is not a concern.

In contrast, a ripple edit adjusts the timeline, shifting subsequent clips to accommodate the new content, whereas an insert edit places the new clip in the timeline, pushing existing clips to the right without overwriting any footage. A trim edit specifically modifies the length of a clip without adding or removing any content but simply adjusts its starting or ending points. It's vital to understand these distinctions to effectively manage clips and edits during the video editing process.
