AI Video Builder

7 min readVideo Creation

The AI Video Builder takes a single product photo and produces a complete short-form video ad — with motion, voiceover, and music — in under a minute. This guide explains how to get the best results, including the hook strategy that separates high-performing ads from ignored ones.

The three-step process

  1. 1

    Select your product from the library. This is your reference — every frame of the video is built around your actual product image.

  2. 2

    Define the video brief: choose an aspect ratio (9:16 for TikTok/Reels, 1:1 for Facebook feed, 16:9 for YouTube), set a target duration (15, 30, or 60 seconds), write or auto-generate a hook, body script, and CTA, choose a voiceover voice and language, and select a music track.

  3. 3

    Generate. AIMS returns a complete video within 45–90 seconds. Preview it, and if you want variations, click "Iterate" to get subtle alternatives while keeping the product and structure intact.

The hook — why the first 3 seconds decide everything

The most important creative decision in any short-form video is the hook — the first 3 seconds. On TikTok and Instagram Reels, 60–70% of viewers stop watching within the first 3 seconds of an ad. If your hook doesn't stop the scroll, the best script in the world won't be seen.

Top-performing ads target a hook rate (percentage of viewers who watch at least 3 seconds) of 30% or higher. Ads with optimised hooks see 30–50% lower cost-per-acquisition compared to the same content with a weak opening.

Effective hooks fall into three psychological categories:

  • Pattern interrupt: Something visually unexpected in the first frame — an unusual angle, a before/after transformation, a dramatic close-up. Stops the thumb mid-scroll.

  • Curiosity gap: A statement that raises a question the viewer needs answered. "This is why your skincare isn't working." "The mistake 90% of coffee drinkers make every morning."

  • Immediate benefit: Lead with the outcome. "Lost 8kg in 6 weeks using this." "Our customers sleep an average of 47 minutes more every night."

Generate 5 hook variants

In the Video Builder, use the "Generate Hook Options" button to produce 5 different opening lines from the same brief. Test the best 2–3 against each other as separate video assets. Hook testing is the single highest-leverage creative experiment you can run.

Voiceover and music

AIMS supports 95+ languages for voiceover using text-to-speech synthesis. Choose from multiple voice styles per language — conversational, authoritative, energetic, warm. For UGC-style ads, a conversational voice that sounds like a person rather than a brand announcement consistently outperforms polished narration.

Music is chosen from a library of licensed tracks sorted by energy level (calm → high energy) and mood (uplifting, serious, playful, cinematic). If you're targeting TikTok, the platform heavily rewards ads that use trending audio — consider exporting your video without music and adding a trending sound natively in TikTok's editor.

85% of social video is watched without sound — always enable captions. AIMS auto-generates captions from your voiceover script and adds them to the video. You can adjust font size, position, and style in the post-generation editor.

Choosing the right aspect ratio

Generate in 9:16 first. If the campaign requires other ratios, use the "Resize" option after generation — AIMS reframes the video for each ratio, adjusting the product position to keep it visible and well-composed in every format.

Why UGC-style videos work

UGC (user-generated content) style videos perform better in paid social because they bypass ad blindness. Viewers have trained themselves to skip anything that looks like an ad. A video that looks like it was made by a real person — slightly imperfect framing, natural voiceover, casual language — gets treated as organic content by both the algorithm and the viewer.

Independent research shows AI-generated UGC-style ads drive 20% lower cost-per-install and 152% higher impression-to-install rates compared to traditional polished creatives. For DTC brands, UGC-style is not a nice-to-have — it's the baseline.
