EU AI Act, 2 December 2026: what dubbed and sponsored creators must show

If you publish dubbed videos, AI-voiced content, or sponsored posts, a date is coming that most creator tools aren't talking about: 2 December 2026.

The EU AI Act's transparency article — Article 50 — has been in force since 2 August 2026. What changes on 2 December is the end of the grace period: the transition window for systems that were already on the market closes, and the marking and disclosure duties apply in full.

We're Ingenious AI, and we build ContentCraft. We are not lawyers, and this post is not legal advice — check the official text or your own counsel for your situation. But we can tell you, plainly, what the Act asks for and what you can do about it this week.

What Article 50 asks for

Two duties matter most to creators:

1. Synthetic audio and video must be marked in a machine-readable format.
If your content is generated or manipulated by an AI system — a dubbed voice, a synthetic presenter, an AI-generated scene — the Act expects that fact to be carried in the content itself, in a format machines can read, not just mentioned in a caption when you remember. (Article 50(2) puts this duty on the provider of the AI system — which is exactly why creators should ask what their tools embed, and keep their own record of what was synthetic in each piece.)

2. Deepfakes and AI-generated public-interest text must be disclosed to the viewer.
If you deploy AI-generated or manipulated content — a deepfake-style video, or AI-written text published on matters of public interest — the audience has to be told it is artificial. (Article 50(4).) Sponsored content sits under disclosure duties of its own in most jurisdictions — in the US, the FTC's endorsement rules already require clear disclosure of paid partnerships — and the direction of travel everywhere is the same: the audience must be able to tell what was made by a machine and what was paid for.

The stakes for getting this wrong are not theoretical. The Act's fines for transparency violations run up to €15 million or 3% of global turnover. Most solo creators will never see a number like that — but platforms, brands, and agencies increasingly ask creators to prove their disclosure before they pay for a campaign. "Trust me" is losing to "show me."

What to do before 2 December

You don't need a compliance department. You need a habit, and a record:

1. Know what's synthetic in every piece you ship. Which voice was dubbed? Which scenes were generated? Which lines were AI-written? If you can't answer that for last week's video, that's the gap to close first. 2. Keep the provenance with the piece. The marking, the disclosure line, and the record of what was generated should travel with the published asset — not live in a chat thread you'll never find again. 3. Make your sponsored-post disclosures checkable. Claims in an ad ("clinically proven," "doubles your…") are where creators and brands get hurt. A scan of the actual claims, against the actual rules, before you post — saved as a record you can show the brand.

The free way to start: ContentCraft's Publish Pack + Dubbing provenance

ContentCraft — built by Ingenious AI — already ships the two halves of this habit:

• Publish Pack scans a sponsored post or script for claim and disclosure problems, and produces a verifiable pack with a public verify link — a page you can send a brand or an agency that shows what was checked, without handing over your whole workflow. - Dubbing provenance pack builds the record for a dubbed piece: what was synthesized, the disclosure lines, and a SHA-256-hashed provenance pack with its own public verify page — so the proof exists independently of you, your memory, or your hard drive.

The Publish Pack scan is free to run. Start with one sponsored post or one dub script — the piece you're publishing next — and see what your record looks like.

The deadline is real, it's 32 days out, and it's the rare kind of deadline that rewards the people who prepared quietly. December 2 doesn't care whether your tool mentioned it. Now yours has.
