Lesson 6 · 18 min
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
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.
Five blocks, with the timing of each. Tap each block.
Skeleton and rules from the INEMA ugc-seedance25 skill (Sep/2026); the label is an addition of this course.
The example product is fictional: the sourdough bread from Dona Lia's bakery.
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").
Write the spoken line for each block in quotes, with the timing next to it. The INEMA skill uses 70 to 80 spoken words in 30 seconds: more than that, and the line gets rushed.
Sound: list what must not appear (loud music under the voice, for example). The look is phone-made: home lighting, no text on screen during generation.
Use the same reference photos of the product (one main one and two or three detail shots) in every generation, as course 1 teaches in the consistency lesson. Change one thing at a time and generate one before the batch.
The product's label and text go in during editing, not in the prompt: the generator tends to distort letters. Check every shot: only one product, the right hands, the same face.
A generated person is never presented as a real customer. A synthetic testimonial carries a label. The promised result is what the product delivers. A real person's face and voice, only with written permission.
No competitor brands and no famous people. The labeling law and the cases are in lesson 7; the platform where you advertise may have its own rules.
The script the page checks, and a request for the AI assistant to draft one from your product.
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>"
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>
Paste the file (or upload the .txt). Test first with the example that passes and the example with errors.
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).
python3 conferir.py anuncio --exemplo; echo "saída: $?" python3 conferir.py anuncio --errado; echo "saída: $?"
$ python3 conferir.py anuncio --exemplo; echo "saída: $?" OK: anúncio com 5 blocos, fala e rótulo · 28 s saída: 0
$ python3 conferir.py anuncio --errado; echo "saída: $?" Ainda não. O que falta: - Falta a linha Rótulo: com a descrição (pelo menos 8 letras). - Plano 3: falta a fala. - Falta citar o aviso de vídeo feito com IA (no Rótulo). saída: 1
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.
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.
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.
Four questions. The explanation appears after each answer.
Question 1 of 4
At what moment should the product appear in the 30 s ad?
Question 2 of 4
The product label came out with crooked letters in the generated shots. What should you do?
Question 3 of 4
Which of these lines crosses the line?
