Which key is used for the overwrite action in a timeline?

The overwrite action in a timeline is typically performed using the B key in most video editing and digital content creation software. This function allows editors to replace existing footage on the timeline with new clips that are added. When the overwrite tool is engaged, any new material placed on the timeline will not create gaps or leave space; it instead directly takes the place of the content already there.

Utilizing the overwrite feature is essential during editing, as it enables a more streamlined workflow, allowing editors to make precise adjustments without cluttering the timeline with additional clips, which can complicate the editing process. Knowing which key performs this function can significantly enhance editing efficiency and improve the final output quality.
