Video Hook
Definition
The first one to three seconds, which is the whole audition. A viewer decides to stay or swipe before your second sentence lands, so the hook has to carry a promise the rest of the video pays off. Everything downstream inherits whatever audience the hook managed to keep.
Hooks come in a small number of shapes and they are not equally durable. A number opens strong and ages badly. A bold claim buys attention and creates a debt the video has to settle. A curiosity gap works right up until an audience learns you never close it, at which point it stops working forever.
The specific failure that kills more first lines than anything else is the dangling opener: a sentence pointing at something the viewer has not seen. "That's her whole month gone." Whose month? The line reads fine in a script document, where scene two sits right underneath it, and lands as noise in a feed. Orange's script checker rejects that shape before a single credit gets spent. Forward-pointing openers are fine, because they point at what is coming rather than at what is missing: "This is the part nobody mentions" promises instead of assuming.
Plan the payoff alongside the promise. If the hook says three mistakes, three mistakes had better appear, and the third had better be the best of them. Videos that break that contract still get watched to roughly the halfway mark and then get trained out of the feed, because the drop-off curve shows the platform exactly where the lie was.
A test that costs nothing: read your first line aloud to somebody who has not seen the video. If they ask a question, the hook works. If they ask what you are talking about, it is a dangling opener.
Every scoring system for short-form weights the opening seconds hardest. Write the hook first so the script has something to aim at, then rewrite it once the rest exists and you know what you are actually promising.

The line that tells a viewer what to do next. Follow, comment, tap the link, or buy. It usually lives in the last three to five seconds, and it works better when the ask is small and specific than when it is broad and polite.
AI Subtitle GenerationCaptions written and timed by software instead of typed by hand. There are two ways to get them: transcribe the audio, or take the text you already wrote and align it to the voice track. The second way cannot misspell a name, because it never guesses at what was said.
AI Music GenerationOriginal background music composed on demand, to a mood and an exact length. You describe the feel and the runtime, a model writes the track. Nothing is licensed from a library, so nothing gets claimed, and a 34-second video gets 34 seconds of music instead of a fade at 30.
Video TemplateA scene-by-scene skeleton for a video: how many beats, how long each one runs, and what job it does. Pick Hook+CTA and you get two scenes across 15 seconds. Pick Tutorial and you get six across 60. The words stay yours, the shape gets decided up front.
