Yes. Kling 4.0 renders sound with the picture, so a creator talking to camera about your product is one take of up to 30 seconds, voice included. Hermoso writes the script, casts the creator and renders it on Kling 4.0.

## Why Kling 4.0 works for UGC ads

- Native sound: the lines are spoken in the render, lip movement and room tone included.
- Vertical 9:16, the format UGC lives in on TikTok, Reels and Shorts.
- Attach your product (up to 5 images) so the creator holds the real thing.
- Up to 30 seconds per take, enough for a hook, a reason and a call to action.

## What UGC ads need

Format One person, phone-held framing, talking to camera

Script About two words per second (24 words in 12 seconds)

Structure Hook, the problem, the product, the result

## How to make one with Hermoso

- Ask for a UGC ad on Kling 4.0: who is talking, where they are, what they say.
