The long definition
A hook is the opening of a video: a visual, a sentence, a sound, or a combination that gives someone a reason to keep watching. In e-commerce, it connects a recognisable situation to a specific product benefit before attention moves elsewhere.
A scroll stopper attracts attention; a hook also sets up what comes next. An unexpected opening only helps if the rest of the video delivers its promise. Compare openings on videos with similar lengths and audiences, using retention data when it is available.
Anatomy: Hook
Build a clear opening that leads naturally into the demonstration. These beats are a planning example, not a universal timing rule.
- 01First frameStart with a readable action, face, or product detail.
- 02PromiseGive the viewer a concrete reason to stay.
- 03Product entryConnect the opening to the product being demonstrated.
- 04HandoffDeliver the first piece of the promised answer.
A concrete example
Illustrative example · insulated bottle
“This is what was still cold after my entire commute.”Open on the bottle being poured, then show the conditions of the demonstration.
The opening creates a specific question and leads into visible evidence. Any temperature or duration claim needs a real test before publication.
Do
- Lead with a visible action.
- Make one clear promise.
- Test one opening variable at a time.
Don't
- Delay the subject with a long introduction.
- Promise an answer the video never delivers.
- Judge the opening on views alone.
How Reacast uses this concept
When preparing a brief in Reacast, describe the reference opening separately from the product demonstration. Specify what to preserve and what to adapt for your product.
