Product ads and UGC: the structures that work and the lines you don't cross

UGC is the ad that looks like a video from an ordinary person: someone holds the product in their hand and talks to a phone camera. With AI you can make it without filming anything, and that is exactly where the risk lives: an invented testimonial passed off as real. This lesson teaches the structures and the rules that keep the ad honest.

Start the lesson
A small tabletop set for filming a product: a smooth glass bottle on a white turntable, a softbox, a reflector and a phone on a mini tripod.

In this lesson you will

  1. 1Choose an ad structure: review, confession, routine, first reaction
  2. 2Build the 30 s skeleton in five blocks with spoken lines
  3. 3Keep the product the same in every shot
  4. 4Label it and don't cross the lines: real person, fake testimonial, false promise

Goal: write a 15 to 30 s ad in five blocks, with a spoken line, the product in frame early, and a made-with-AI content label.

01The skeleton of a 30-second ad

Five blocks, with the timing of each. Tap each block.

Click each block of the diagram to see what it does.

Skeleton and rules from the INEMA ugc-seedance25 skill (Sep/2026); the label is an addition of this course.

02How to write the ad, step by step

The example product is fictional: the sourdough bread from Dona Lia's bakery.

1. Choose the structure

Review: the person uses it and comments. Confession: problem, ritual, result. Routine: the product in everyday life. First reaction: open the box and react. 15 s selfie test: short hook, one benefit, casual ending.

Choose by product: the bread calls for routine (the morning of whoever buys it) or confession ("I gave up on supermarket bread").

03Templates to copy

The script the page checks, and a request for the AI assistant to draft one from your product.

anuncio.txt (template)
Product: <what it is; real or fictional>
Structure: <review, confession, routine, first reaction or selfie test> · <9:16 or 16:9>
Label: <e.g.: video made with AI; the person is fictional>
# n | block | time | what you see | line
1 | hook | <n> s | <the product enters the frame> | line: "<sentence>"
2 | what it is | <n> s | <...> | line: "<sentence>"
Request to the AI assistant (ad draft)
You are a scriptwriter of short UGC-style ads. Write a <duration>-second ad for the product below, in five blocks, one line per block:
n | block (hook, what it is, demonstration, result, ending) | time | what you see | line: "..."
Rules:
- the product appears in the frame within the first three seconds;
- 70 to 80 spoken words in 30 s (proportional if it is shorter);
- only promise what the product delivers: <what it actually delivers>;
- no hard selling, no competitor brands, no famous people;
- the person is fictional and the script ends with the line "Label: video made with AI; fictional person".
Product: <description>
Structure: <chosen structure>

04Check your ad

Paste the file (or upload the .txt). Test first with the example that passes and the example with errors.

anuncio.txt

05Optional: check in the terminal

Only for people who already use a terminal. In the folder of the course you downloaded from GitHub; for your own file, replace --exemplo with its name (anuncio.txt).

Terminal (in the course folder)
python3 conferir.py anuncio --exemplo; echo "saída: $?"
python3 conferir.py anuncio --errado; echo "saída: $?"
Example from the repository
$ python3 conferir.py anuncio --exemplo; echo "saída: $?"
OK: anúncio com 5 blocos, fala e rótulo · 28 s
saída: 0

06Practice

A product of yours (real) or Dona Lia's bread (fictional). Generating the video is up to you and the tool you have; the script is what gets checked here.

Ad · five blocks with a label

25 min

Choose a structure and write the Produto, Estrutura and Rótulo lines and the five blocks with time, what is seen and the line. Paste it into "Check your ad" and download the anuncio.txt to the project folder.

Done when: the page answers OK: anúncio com [n] blocos, fala e rótulo · [s] s, with the total between 15 and 30 s, and the anuncio.txt is in the project folder.

Promise · only what the product delivers

10 min

Read the result block and write, next to the anuncio.txt, a "Prova:" line saying where each promised thing comes from (does the product do that? who confirmed it?). Cut from the script whatever has no proof and check again.

Done when: the page keeps answering OK: … and each promise in the result block has its own "Prova:" line in the file.

07Quick quiz

Four questions. The explanation appears after each answer.

Question 1 of 4

At what moment should the product appear in the 30 s ad?

08To keep

Product in the hookFive blocks in 30 s, with the product in the first three seconds.
Same productLocked reference, one change at a time, product text added in the edit.
Label and truthA generated person is not a real customer; only promise what the product delivers.
