Design a commercial. Return JSON {"hook":"...","prompt":"...","format":"...","cta":"..."}: hook - visual hook for the first 2 seconds, prompt - description of the scene with the product in action and the plan, format - aspect ratio (for example 9:16), cta - short call to action.
A video for social networks lives by its own laws: a vertical frame of 9:16, a length of 8-15 seconds and a battle in the first 2 seconds. The mechanics of attention are simple - the viewer scrolls through the tape with his thumb, and if there is no hook in the first frame, he will scroll through. Build the video like an inverted pyramid: the brightest is at the beginning, not at the end. The hook is a visual surprise or promise (“this is what will happen if...”), not a logo. Technique for a product: show the product in action and in hand, close-up, with one clear camera movement (zooming into a part). Insider: shoot “with text and sound” - leave air in the frame above and below the captions, otherwise they will block the face or product. The second technique is to end with a call-action, but short: one action, one phrase. A typical rookie mistake is a horizontal film frame shoved into a vertical film: black bars kill engagement. Immediately set the aspect ratio to 9:16 and keep the main subject in the central third of the frame.
