Scrub
Dragging through the timeline like Gollum through Mordor — slow, deliberate, searching for something precious.
Scrubbing is the act of manually dragging the playhead back and forth through a video timeline or source clip viewer at a variable, user-controlled speed — faster than real-time to rapidly navigate through footage, or slower to find a precise moment frame by frame. When you click and drag the playhead in an editing timeline, the video plays at whatever speed and direction corresponds to your drag speed and direction — drag right quickly and the video plays forward fast; drag left slowly and you can step backward almost frame by frame. This manual scrubbing is distinct from normal playback (fixed speed, forward only) and allows editors to navigate footage at a pace suited to their search.
Audio scrubbing — when the audio plays at the scrubbed speed, including the characteristic distorted sound of compressed or expanded audio — allows editors to hear the dialogue content even while scrubbing faster than normal playback. This audio playback during scrubbing (a feature that can be toggled on or off in most NLEs) lets the editor locate spoken words by sound, finding the exact frame of a specific word or phrase by listening to the scrubbed audio rather than reading transcripts or watching at full speed. Some editors develop an intuition for recognizing dialogue from its scrubbed audio character, dramatically accelerating the process of finding specific moments in long interview footage.
For producers who are not professional editors but review footage or rough cuts, scrubbing is the primary navigation tool. Clicking anywhere in a timeline or video player and dragging to move quickly through the content — finding the specific moment that needs to be marked or discussed — is the intuitive equivalent of fast-forwarding with the ability to stop at any point instantly. In most video review tools (Vimeo Review, Frame.io, YouTube Studio), clicking on the progress bar and dragging performs a form of scrubbing that allows efficient navigation through the video. Understanding this as a named technique helps in communicating with editors: "scrub to about the two-minute mark" is precise shorthand for "navigate the playhead to approximately the two-minute position in the timeline."
