Direct answer

Usually when a realistic AI avatar or synthetic voice is presented as if it were a real recording. Disclose the avatar and voice separately and retain the likeness-consent evidence. A stock or obviously virtual presenter can still trigger broader platform rules, while a custom avatar adds consent and likeness questions. Verify the final export before publication.

Applies when

  • Photoreal stock avatar presents a product — Disclosure required.
  • Custom avatar of an employee — Human review required.
  • Clearly cartoon-like virtual host — Disclosure recommended.

Doesn't apply when

  • The tool was used only for ideation and no generated material appears in the final asset.

Worked decision

Example

Photoreal stock avatar presents a product

Decision: Disclosure required

Assess the final output rather than the tool name alone.

Presenter and voice are AI-generated.

Next steps

Required action

  1. Record exactly how HeyGen was used and which component of the final asset it affected.
  2. Verify the final export instead of assuming its provenance status: C2PA not established in the reviewed official product documentation.
  3. Apply the destination platform’s native label and precise audience-facing wording where the resulting content triggers them.

Publishing layer

Platform differences

Detection and native labels

YouTube can require altered-content disclosure for a realistic synthetic presenter or voice.

Policy threshold

TikTok requires AIGC labelling for realistic generated video and audio.

Publishing workflow

Meta may label declared content or detect technical AI indicators.

Does HeyGen generate C2PA or other provenance?

not-established

C2PA not established in the reviewed official product documentation

HeyGen documents rendered avatar video and optional custom visual watermark overlays. The reviewed official API documentation does not establish universal C2PA Content Credentials on exported videos. Verify the actual output and preserve a separate manifest.

EU implications

  • A photoreal avatar can be a deepfake when it resembles a real person or would falsely appear authentic.
  • A custom avatar raises consent, likeness and contractual questions beyond Article 50.
  • A visible HeyGen or custom watermark is not equivalent to a complete legal assessment.
