# The UGC ad format: shape, length and structure

The UGC ad format is a short vertical video with a personal tone: framed for a phone screen, captioned, opening with a hook and built around one product story. Length varies, but most run well under a minute. AIUGCAdGenerator delivers that format in every campaign: three finished UGC-style video ads, each a vertical 9:16 MP4 of about 15 to 30 seconds.

Three ads. One product story.

## What the UGC ad format is

The UGC ad format combines a shape (vertical, for phones), a length (short), a tone (personal and plain-spoken) and a structure (hook, moment, product, reason to care, call to action). Each of those can be varied, but changing too many at once makes an ad look like a regular commercial.

_Format is not authorship. A UGC-format ad does not have to be made by a customer, and it must never claim to be when it is not._

## The format AIUGCAdGenerator delivers

| Attribute | Value |
|---|---|
| Shape | Vertical 9:16 |
| File type | MP4 |
| Length | About 15 to 30 seconds |
| Ads per campaign | Three, from the same brief |
| Angles | A different opening, story and reason to care in each |

## Format choices that matter

**Vertical framing.** A 9:16 frame fills a phone screen. Check the current specifications wherever you publish before you upload.

**Captions.** Many viewers scroll with the sound off, so captions carry the story.

**Pacing.** UGC ads move quickly from hook to product. Every second should earn the next.

**One story per ad.** The format rewards focus. Save other benefits for other versions.

## How to get ads in the UGC format

1. **Share a product URL or brief** No footage is required.
2. **Choose a plan and confirm** Request the campaign after checkout or after selecting a credit.
3. **Download the MP4s** Check the claims and creative, then choose what to publish or test.

## Built into every campaign

- **Vertical MP4s**: Each ad is a vertical 9:16 MP4, about 15 to 30 seconds long.
- **Three angles**: The three ads differ in opening, story and reason to care.
- **Captions and editing**: Captions and editing are included as appropriate.
- **Finished files**: You review finished, playable videos.

## Format limits

- **Vertical only**: Ads are delivered as vertical 9:16 MP4s.
- **Your review**: You review the finished files, claims and suitability before publishing, and follow platform rules.
