The structure of a short UGC Ad script
A 15 to 45 second UGC Ad has room for very little, so every line has one job:
- Hook: the first line, the reason to keep watching.
- Problem: the frustration, in the customer's words.
- Product: what it is and the one feature that fixes the problem.
- Proof: a fact you can stand behind, such as a spec, a material or a guarantee.
- Call to action: the offer or where to buy.
Spoken scripts read best in short, plain sentences, the way people actually talk to a phone camera.
How to brief an AI script
- Say who the ad is for and what problem it solves.
- Give one angle per script. A second angle is a second video.
- List the facts the script may use, so it does not invent any.
- Set the tone: casual, skeptical, excited or matter-of-fact.
- Never ask for lines where the actor claims personal results or long-term use: an AI actor must not be presented as a real customer.
How EchoUGC writes and uses the script
You describe what you sell in a few lines, and your brand brief (company name, what you sell, who your customer is, brand voice) keeps the script on message. EchoUGC writes the script, casts an AI actor with native lip-sync, and renders the finished 9:16 1080p video with captions, usually in under 10 minutes.
Revisions are an instant re-gen, not a new shoot: change the script, hook or actor and render again. You only pay for successful renders, and a video of up to 45 seconds is 100 credits.
Frequently asked questions
How long should a UGC Ad script be?
Short enough to say in the video's length with natural pauses. On EchoUGC, videos of up to 45 seconds are 100 credits, and the Length menu defaults to 30 seconds.
Can I change the script?
Yes. Revisions are an instant re-gen: change the script, hook or actor and render again. To steer the first draft, put the points you want covered in the brief.
Does the script use my brand voice?
Yes. Your brand brief, including your brand voice, keeps scripts and hooks matched to your product and voice.
