Talking avatar: studio, voice and consent
A talking avatar is the most expensive step in the factory and the most sensitive: it's a person's face and voice. In this lesson you'll see how the studio fits into the pipeline and write two pieces of your own: the avatar's consent form and a gate that doesn't let any generation start without a valid consent form.
Start the lesson
In this lesson you will
- 1Whose avatar it can be: only the person's own, with a consent form
- 2The seven fields of the consent form: person, what it authorizes, use, languages, validity, revocation and label
- 3A gate in a script before the studio, because the engine's own is just a written rule
- 4HeyGen's Avatar V as a dated example (Apr/2026), not as a fixed step
Goal: write the consent form for your avatar and put in a gate that closes any generation without a valid consent form.
01The path to the studio
Click each step. The studio only opens after the gate.
Click each block in the diagram to see what it does.
explicavideos and refazvideo ask for the APROVADO_HEYGEN file before start, but the code doesn't check it. The gate in this lesson is the one that really closes.
02The studio, in Oct/2026
Dated example: names and features change. What doesn't change is the consent form.
1. HeyGen
Avatar V, introduced in Apr/2026: identity created from about 15 s of footage, separating identity from appearance; in May/2026, motion direction in natural language (research §3). It's the studio INEMA's engines use, through the subscription.
2. Others
Synthesia Express-2 (Sep/2025, full body). Hedra Omnia and OmniHuman 1.5 appear in secondary sources: reported, not confirmed in an official source as of 10/19/2026.
3. Lip sync
In generators with native audio, the mouth comes out together with the speech. In avatars, the studio syncs from the audio or from the text. Generators and native audio: course 1.
4. Label and law
It also works with no avatar at all: local voice and scenes, like the demo in lesson 3 and course 3. The AI-generated content label, image and voice rights, and the AI Act are covered in course 2, lesson 7. Here the consent form only requires that the label exists and mentions AI.
03The consent form
Fictional example in the kit. Yours is the same, with your own details.

The second file is the same consent form without the Rótulo line. The field labels also work in English and Spanish (Person, Label, Etiqueta…).
04The gate
The script doesn't call any studio: it only decides whether you can open the studio and how many seconds you will ask for.
File · kit/portao-avatar.sh
#!/usr/bin/env bash
# portao-avatar.sh — porta de entrada de qualquer geração de avatar: sem termo conferido, nada segue.

echo "roteiro: $p palavras ≈ $(( (p * 60 + 139) / 140 )) s a 140 palavras/min"

Put the gate call as the first line of your production script, before start: with set -e, exit code 1 stops everything.
05Practice
Your consent form and your gate.
E2 · Your consent form
15 minWrite ~/meu-termo.md with the seven fields, using your own details and whatever expiration date makes sense for you.
Done when: python3 ~/projetos/formacao-cinema-ia-fabrica-v72/kit/conferir-consentimento.py ~/meu-termo.md; echo "saída: $?" → OK: termo de [your name] · 7 campos · válido até … and saída: 0.
E3 · Gate on your script
5 minRun the gate with your consent form and one of your own scripts as a text file.
Done when: bash ~/projetos/formacao-cinema-ia-fabrica-v72/kit/portao-avatar.sh ~/meu-termo.md [your-script.txt]; echo "saída: $?" → PORTÃO ABERTO and saída: 0.

The explanation appears after you answer.
Question 1 of 3
A client asks for a video with the avatar of a famous presenter. What does this lesson's consent form allow?
Correct
The Pessoa field is who appears and speaks, and that person is the one who authorizes. A label does not replace consent.Not that one

Why put a gate in a script if the engine already asks for APROVADO_HEYGEN?
Correct
A rule that depends on someone remembering fails on a busy day. A script that exits with code 1 really closes the gate.Not that one
