Cold open

A cold open is a technique in short-form and documentary video where the story begins at its most gripping moment before any title card, introduction, or context appears. The viewer is dropped into the middle of an event, a question, or a scene, and only after that hook does the video explain what they are watching. In vertical documentary formats it usually occupies the first three to five seconds.

Why it matters

Retention on a Short is decided in the first seconds. A creator who opens with "In this video we will look at" gives the viewer nothing to stay for, because the payoff has not started yet. A cold open reverses the order: the payoff comes first, the explanation second. Creators who do not understand this term often bury their strongest fact behind a branded intro or a slow setup, then read low retention graphs without knowing which structural choice caused them.

It also changes how you script. If you know the opening must be a self-contained moment, you plan the script around one striking fact or scene rather than around a topic description. That decision affects research, voiceover pacing, and even thumbnail design, since the cover image typically matches the cold open rather than the general subject.

An example

A true crime Short about an unsolved case can open with the discovery itself: "The hikers found the tent still zipped from the inside." Only after that line does the narration step back and explain who the hikers were, where this happened, and what investigators concluded. The same script opened the other way would start with the location and date, and the striking detail would arrive too late to hold the viewer.

Terms people confuse this with

• B-roll: supplementary footage shown while narration continues; a cold open is a structural choice about what starts the video, B-roll is about what fills it.
• Cutaway: a brief shot that interrupts the main footage to show something else; a cutaway serves the current scene, a cold open replaces the expected beginning entirely.
• Aspect ratio: the frame shape of the video, unrelated to narrative structure but relevant because cold opens must land within the small vertical frame.

Where this shows up in ViewMade

ViewMade scripts place a measured fact as the first spoken sentence of every Short, so the video opens on its strongest claim rather than on an introduction.
