An eight-second product ad works best when it gives the viewer one clear reason to care, then makes the product the answer. Write the hook, product reveal and payoff as timed visual beats, and set duration, aspect ratio and audio in the generator to match where the ad will run. Don't rely on the prompt text for those.

## [Give the ad one job: hook, then payoff](#give-the-ad-one-job-hook-then-payoff)

A very short ad is not a compressed product brochure. Pick one problem or desire, show one product benefit, and end on one memorable image or line. If you try to fit a lifestyle setup, several features, a testimonial, packaging details and a call to action into the same eight seconds, every beat ends up competing with the others.

A practical storyboard is:

- **0–2 seconds: hook.** Show a recognizable problem, surprising action or sensory detail.
- **2–5 seconds: reveal.** Make the product and its relevant feature unmistakable.
- **5–8 seconds: payoff.** Show the result, a satisfying use moment, or a concise line that gives the viewer a reason to remember it.

Treat those as editing targets, not a promise that a video model will hit each timestamp exactly. If the product is small, unfamiliar or visually complex, give the reveal more time and make the opening simpler. If the product is immediately recognizable, the hook can move faster.

## [Learn from three prompt patterns](#learn-from-three-prompt-patterns)

The three examples below come from our community gallery. Each prompt is quoted exactly as the creator shared it, with the settings the clip was generated with. They show three useful structures: a problem-first reveal, a tactile package-and-taste payoff, and a playful creator moment followed by a flavor lineup. They also share a common mistake: the duration and aspect ratio written in the prompt don't match the settings the clip was generated with. The storyboard describes the shots; the generator settings decide the length and shape of the clip.

### [Example 1: Soaked shoes as the opening hook](#example-1-soaked-shoes-as-the-opening-hook)

**Settings:** Veo 3.1 Fast · 8s · 16:9 · with audio · [Watch it in the gallery](https://www.imaginary.app/gallery/4second-vertical-video-realistic-cinematic-productproblem-showcase-5d2a39)

**Prompt (shared by a creator in the community gallery):**

> 4-second vertical video, realistic, cinematic, product-problem showcase.
>
> 0-1.5s: A young man arrives home from work, opening the door to a modern apartment, tired expression, evening light through windows.
>
> 1.5-2.5s: Close-up on his face — disgusted, annoyed expression as he looks down, wrinkling his nose.
>
> 2.5-4s: Camera tilts and zooms down slowly to his feet, revealing visibly soaked, sweat-drenched shoes. Slow zoom emphasizes the wet fabric and discomfort.
>
> Style: realistic, natural indoor lighting, smooth camera movement, shallow depth of field on the zoom shot, relatable everyday setting.
>
> Aspect ratio: 9:16, resolution 1080x1920, vertical format.

This prompt makes the problem legible through a sequence of increasingly specific cues: arriving home, reacting with disgust, then revealing soaked shoes. That gives the opening a clear visual question and a concrete answer, rather than asking the viewer to infer the problem from mood alone. Borrow the downward reveal and everyday setting if discomfort is the hook. Change the timing and framing before using it as an eight-second vertical ad: its text calls for four seconds and 9:16, while the clip was generated at 8 seconds and 16:9. Pick one target duration, set 9:16 in the controls for a vertical deliverable, and remove the conflicting ratio line from the prompt. For an eight-second version, use the extra time to hold on the shoes or show the product solving the problem, not simply to stretch the arrival.

### [Example 2: A tactile snack reveal](#example-2-a-tactile-snack-reveal)

**Settings:** Veo 3.1 Lite · 4s · 16:9 · with audio · [Watch it in the gallery](https://www.imaginary.app/gallery/scene-10-title-taste-payoff-package-reveal-6ff283)

**Prompt (shared by a creator in the community gallery):**

```json
{
  "scene": 10,
  "title": "Taste Payoff / Package Reveal",
  "duration_seconds": 2,
  "aspect_ratio": "9:16",
  "style": "Dynamic product close-up, satisfying tactile visuals",
  "subject": "Small glass bowl, snack pouch",
  "environment": "Kitchen counter surface",
  "action": "Shot A: high-angle close-up of a small glass bowl spinning fast on the counter. Shot B: first-person POV close-up of thumbs peeling open the top of a snack pouch to reveal walnuts inside",
  "camera": {
    "shot_type": "High-angle close-up, then first-person POV close-up",
    "movement": "Spinning motion blur, then POV hand movement",
    "lens_feel": "Macro/close-up, crisp detail"
  },
  "lighting": "Bright even kitchen lighting",
  "text_overlay": {
    "style": "Lower-third centered caption, white sans-serif font, soft black drop shadow; final line pops in bold capitalized formatting",
    "position": "Lower third of frame",
    "wording": "it's a habit you'll actually stick to\nbecause they taste so good\nSO GOOD"
  },
  "dialogue_voiceover": "It's a habit you'll actually stick to because they taste so good.",
  "sound_design": "Background music continues; crisp synced 'pop' and 'tear' sound of packaging opening",
  "mood": "Satisfying, exciting, appetite-triggering",
  "negative_prompt": "no muffled or missing sound sync, no slow-motion effect"
}
```

This prompt combines a sensory action, a package opening, a taste-oriented voiceover and a sound cue. The crisp opening sound supports the visible tear, while the copy gives the sequence a reason to matter beyond attractive food imagery. Borrow that sound-and-action pairing and the close-up emphasis. Change the shot plan if the pouch itself is the product hero: the spinning bowl and the first-person opening are two separate actions, and the prompt gives the scene two seconds even though the clip was generated at four. The written aspect ratio is 9:16 while the setting is 16:9. Choose the frame in the settings, then decide whether the four-second clip should hold on one action or make a deliberate cut between both. Keep the payoff line short enough to read and hear comfortably.

### [Example 3: Creator energy and flavor range](#example-3-creator-energy-and-flavor-range)

**Settings:** Veo 3.1 Lite · 4s · 16:9 · with audio · [Watch it in the gallery](https://www.imaginary.app/gallery/scene-7-title-playful-snacking-flavor-lineup-6febdc)

**Prompt (shared by a creator in the community gallery):**

```json
{
  "scene": 7,
  "title": "Playful Snacking + Flavor Lineup",
  "duration_seconds": 2,
  "aspect_ratio": "9:16",
  "style": "UGC lifestyle, energetic and playful",
  "subject": "Female creator, casual outfit, playful expression",
  "environment": "Kitchen counter with four additional flavor bags lined up",
  "action": "Shot A: creator tosses a walnut into the air and catches it in her mouth, medium shot, smiling. Shot B: low-angle static shot of creator inspecting a snack pouch with the other flavor bags visible beside her",
  "camera": {
    "shot_type": "Medium shot, then low-angle static shot, two quick cuts",
    "movement": "Static per shot with fast cutting between them",
    "lens_feel": "Natural home-video / UGC look"
  },
  "lighting": "Bright natural kitchen lighting",
  "text_overlay": {
    "style": "Lower-third centered caption, white sans-serif font, soft black drop shadow",
    "position": "Lower third of frame",
    "wording": "I can snack without feeling guilty\nand they taste amazing"
  },
  "dialogue_voiceover": "I can snack without feeling guilty, and they taste amazing.",
  "sound_design": "Background music runs continuously",
  "mood": "Fun, lighthearted, genuine",
  "negative_prompt": "no forced or stiff acting, no unnatural product placement"
}
```

The prompt pairs a playful creator action with a lineup of flavors, so it can communicate both an informal use moment and product variety. The home-video camera language and natural kitchen light support that casual feel, and the continuous music gives the short scene a simple audio bed. Borrow the contrast between a human moment and a product display. Change the beat allocation if the lineup is the main selling point: the catch and the pouch inspection compete for attention, and the prompt describes a two-second scene while the clip was generated at four seconds. Its 9:16 instruction also conflicts with the 16:9 setting. Choose one frame shape, then reserve enough of the clip for the flavors to be seen rather than relying on a quick glance.

## [Turn the beats into a timed prompt](#turn-the-beats-into-a-timed-prompt)

Write the action first, then add only the camera, lighting and sound details that help the viewer read that action. A prompt can be vivid without assigning a new shot, subject or camera move to every second. Too many rapid cuts can make a short clip feel busy and leave the product on screen for too little time.

### [Copy this structure](#copy-this-structure)

```text
Create an 8-second [format] product ad for [product] aimed at [audience].

0-2s - Hook: [one visible problem, desire, or surprising action].
2-5s - Product reveal: [show the product clearly; demonstrate one benefit].
5-8s - Payoff: [show the result or satisfying use moment; end on product].

Camera: [one or two shot types and a simple movement].
Setting and light: [specific environment and lighting].
Audio: [dialogue or sound cue that supports the action; otherwise no dialogue].
Keep [important product feature] visible. Avoid [one likely failure, such as obscured packaging].
```

Here is the structure filled in for an invented product. This prompt is our own illustration, not a gallery example:

```text
Create an 8-second vertical product ad for a matte-black insulated water
bottle aimed at city commuters.

0-2s - Hook: at a sunny bus stop, a commuter sips from a thin plastic
bottle and grimaces at the warm water.
2-5s - Product reveal: close-up as she unscrews the matte-black bottle;
ice cubes clink as she pours cold water into the cap.
5-8s - Payoff: she drinks, relaxes and smiles; the shot settles on the
bottle standing upright on the bench, with empty space above it.

Camera: handheld medium shot, then a slow push-in to a close-up; the
final shot is static.
Setting and light: city bus stop, bright midday sun.
Audio: light street ambience and the clink of ice; no dialogue.
Keep the bottle's matte-black finish and silver cap clearly visible.
Avoid hands covering the bottle in the final shot.
```

Replace vague directions such as "make it exciting" with something the camera can show: "the pouch opens and the snack lands in a glass bowl." Give dialogue a job too. A short line can reinforce the payoff, but it should not narrate an action the viewer already understands unless that repetition is intentional. Our [cinematic and product-shot prompts](https://www.imaginary.app/prompts/cinematic-and-product-shots) and the [Veo 3.1 prompting guide](https://www.imaginary.app/guides/veo-3-1-prompting-guide) have more camera and lighting phrasing you can borrow.

If you need a precise logo, price or legal line, add it as a separate finishing step in your editor rather than relying on generated lettering. Keep the generated shot clean enough to leave room for the final graphic; that is why the example above asks for empty space above the bottle.

### [Anchor the product with your own photo](#anchor-the-product-with-your-own-photo)

A text-only prompt makes the model invent your product's look. If the packaging or shape has to be right, use the **Image-to-Video** tab. The image you upload becomes the first frame of the clip, and an optional **Last Frame Image** sets where it ends. For a hook-to-payoff ad, a clean packshot of the real product as the last frame gives the payoff a fixed target, and the prompt describes how the scene gets there. Our [product ads guide](https://www.imaginary.app/use-cases/product-ads) walks through preparing product photos for this.

## [Set duration, aspect ratio, resolution and audio deliberately](#set-duration-aspect-ratio-resolution-and-audio-deliberately)

On Imaginary, Veo 3.1 runs in Lite, Fast and Quality modes, with clips of 4, 6 or 8 seconds, 16:9 or 9:16, at 720p or 1080p (4K on Fast and Quality only), and optional audio. Choose the clip length to fit the deliverable, not merely because the storyboard uses a familiar duration.

Iterate cheaply, then render the final. Most of what you are checking in early rounds (are the beats in order? is the product readable?) shows up in a low-cost draft. For an 8-second clip:

| Mode            | 720p, no audio | 1080p, with audio | 4K, with audio |
| --------------- | -------------- | ----------------- | -------------- |
| Veo 3.1 Lite    | 2 credits      | 5 credits         | not available  |
| Veo 3.1 Fast    | 6 credits      | 10 credits        | 22 credits     |
| Veo 3.1 Quality | 13 credits     | 26 credits        | 38 credits     |

Aspect ratio does not change the cost. A Lite draft won't look identical to a Fast or Quality render, so use drafts to test the storyboard, not the final look. The [Veo 3.1 cost calculator](https://www.imaginary.app/tools/veo-3-1-cost-calculator) covers 4- and 6-second clips and every other combination.

Eight seconds is not placement-neutral. For Google's Demand Gen campaigns, the minimum video length is five seconds, and videos shorter than 10 seconds are ineligible to serve on YouTube in-stream. Demand Gen video ads can appear across the Discover feed, YouTube feeds, YouTube in-stream, YouTube Shorts, Gmail and the Google Display Network, so an eight-second cut can still run in placements other than in-stream. Google also recommends videos longer than 15 seconds to maximize reach across formats ([Google Ads Demand Gen specifications](https://support.google.com/google-ads/answer/17141078?hl=en-GB)). If in-stream matters, plan a longer edit: generate the hook and the payoff as separate clips and cut them together, rather than trying to stretch one clip.

Match the aspect ratio to where the ad will run. Google recommends 1080 × 1920 for 9:16 vertical assets (its recommended shape for YouTube Shorts), 1080 × 1350 for 4:5 vertical, 1080 × 1080 for square and 1920 × 1080 for horizontal Demand Gen assets ([Google Ads Demand Gen specifications](https://support.google.com/google-ads/answer/17141078?hl=en-GB)). Our generator produces 16:9 or 9:16, so a 4:5 or square placement means cropping in your editor. Keep the product near the center so a crop doesn't cut it. A prompt that says "vertical" does not change a landscape setting: set the ratio in the controls, and remove contradictory ratio instructions from the text.

Choose audio only when it contributes something: a spoken hook, a useful product sound or a music-led mood. If the sound is essential to understanding the beat, specify what should be heard and when. If it is not, don't clutter the prompt with a soundscape that distracts from the product. The generator labels audio as experimental, so some clips may come back without sound. Check for it before you build the edit around a line of dialogue.

## [Review the result for timing, clarity and framing](#review-the-result-for-timing-clarity-and-framing)

Watch the clip once without pausing. Can you identify the hook, the product and the payoff? If not, simplify the beat that is doing too much. Watch again with the sound off to check whether the product story still reads visually, then listen without looking to catch dialogue that is rushed or sound effects that land too early.

Check the first frame as well as the last. The opening needs to establish a readable situation, not just a camera move. The ending should leave the product visible long enough to register. For vertical placements, keep faces, packaging and any planned overlay away from the edges of the frame. If the product is difficult to recognize, give it a clearer, larger reveal before adding more stylistic detail.

A useful revision rule is to change one cause at a time. If the hook is unclear, rewrite the opening action; if the product is hard to see, change its position or give the reveal a closer shot. Keep the other beats stable so you can tell whether the edit fixed the actual problem.

When the storyboard reads cleanly, take it to [the generator](https://www.imaginary.app/generate) and choose settings for the placement you have in mind.
