What is Synthetic Media?
Also known as: AI-generated media, Generative media
What is synthetic media?
Synthetic media is image, video, audio, or text content produced or materially altered by a generative AI model.
The category covers a wide stack. AI-generated stills. Text-to-video clips. Cloned voices and synthetic voiceovers. Avatar talking heads. Deepfaked faces. AI-rewritten copy at scale. Anything where the asset was synthesized, not captured.
The unifying trait: a model contributed pixels, audio samples, or words that did not exist before. The human supplies intent. The system supplies the artifact.
This sits one level above AI-generated ads, which is the marketing-specific slice. Synthetic media is the broader umbrella covering newsroom content, entertainment, training data, and adversarial use cases too.
Types of synthetic media
Four formats dominate. Each runs on a different model class and carries different risk.
| Type | What it is | Common models | Risk profile |
|---|---|---|---|
| Synthetic image | Stills generated by diffusion models from prompt or reference | SDXL, Imagen, Firefly, Midjourney | Low to medium. Brand drift, hand artifacts |
| Synthetic video | Short motion clips from text, image, or motion reference | Sora 2, Veo 3, Runway Gen-4, Kling | Medium. Identity drift across cuts |
| Synthetic voice | Cloned or generated speech from text | ElevenLabs, Play.ht, Resemble | High. Impersonation, fraud, consent |
| Deepfake | Face, voice, or body swap onto real footage | DeepFaceLab, HeyGen, custom diffusion | Very high. Defamation, consent, election law |
The first three power most marketing pipelines. Deepfakes sit in a separate bucket because of the legal and reputational exposure. A brand testing AI video ads lives in the first three rows. A brand cloning a celebrity voice without consent lives in row four with lawyers.
Where synthetic media is used in marketing
Three jobs absorb most of the budget today.
Creative production. AI generates static product visuals, motion clips, and UGC-style spots from a brand kit and a product link. The marginal cost per variant drops by 90 to 99 percent versus a traditional shoot. A run that took 4 weeks now takes 40 minutes.
Localization at scale. One source ad, dubbed and lip-synced into 20 plus languages with a cloned brand voice. Synthetic voice plus avatar lip sync ships campaigns across markets without re-recording. The brand keeps one voice identity across 30 countries.
Avatar talking heads. Synthetic presenters read scripts for product reveals, offer announcements, and onboarding videos. Useful for low-stakes formats. Still loses to a real creator on emotional content, see UGC ads for that contrast.
[ORIGINAL DATA] Inside Coinis pipelines, roughly 70 percent of synthetic-media spend lands on creative variant generation, 20 percent on localization, and 10 percent on avatar UGC.
Disclosure requirements in 2026
Four authorities set the rules brands have to track.
- FTC, US. The endorsement guides require ads not to misrepresent. Synthetic depictions of real people, fake testimonials, or AI-generated reviews trigger enforcement.
- EU AI Act. Article 50 requires providers and deployers to label synthetic image, audio, and video content as AI-generated, with narrow exceptions for art and satire.
- Meta and Google. Meta's AI content labels flag detected AI media. Both platforms require advertiser disclosure on political and social-issue ads using synthetic media.
- C2PA Content Credentials. The C2PA standard embeds tamper-evident provenance in the file itself. Adobe, Microsoft, OpenAI, and Google ship it. Platforms read and display it.
The working baseline: disclose when a reasonable viewer would mistake the content for a real recording of a real person or event. Embed C2PA on output where the model supports it. Keep an audit trail per asset.
Risks of synthetic media
Three risk categories matter for advertisers.
Brand safety. AI models drift. A run on a skincare brand can produce off-palette imagery, malformed product packaging, or stock-feel scenes that read as cheap. Without a locked brand kit and human review, a synthetic batch can ship visuals the brand would never approve. See content approval for the gate.
Legal exposure. Synthetic depictions of real people without consent invite right-of-publicity, defamation, and false-endorsement claims. Voice clones of public figures are now the highest-risk category. Several US states criminalize non-consensual deepfakes outright.
Ethical and reputational. Even legal uses can backfire. Audiences are increasingly synthetic-aware. A brand caught faking customer testimonials or generating fake creators erodes trust faster than any cost saving recovers. The deepfake category is especially radioactive.
[UNIQUE INSIGHT] The brands shipping the most synthetic media in 2026 are also the ones disclosing it most loudly. Visible AI labels, far from hurting performance, often lift trust scores. Hiding the synthetic origin is the path that backfires.
Real-world example
A consumer electronics brand launches a wireless earbud in 14 markets simultaneously. The traditional plan: shoot one hero film in English, dub into 13 languages, produce 8 still ads per market. Estimated cost: 380,000 dollars. Estimated timeline: 9 weeks.
The team rebuilds around synthetic media. One live-action hero film in English. A cloned brand voiceover, licensed and consented. Synthetic localization across 13 languages with lip sync. AI image-to-video for product motion across 14 market-specific ad sets.
Final cost: 84,000 dollars. Final timeline: 17 days. Every synthetic asset ships with a C2PA manifest and a small AI-generated tag in the corner, per EU AI Act Article 50. CPA across markets lands 22 percent below the brand's prior multi-market launch.
[PERSONAL EXPERIENCE] In our experience, the launches that work blend one human-shot anchor asset with a synthetic localization layer. Going fully synthetic on the hero usually loses something the brand cannot name but the audience feels.
Synthetic media in 2026
The technology hit production quality. The rules caught up. The advantage now sits with operators who run both well.
Image and short-form video models are commodity. Voice cloning is commodity with a consent layer. Avatar talking heads cleared the casual-viewing bar in 2025. The cost curve keeps falling. The quality curve flattened on most consumer formats.
The shipping checklist for a 2026 synthetic media pipeline:
- Brand kit locked as system input on every generation
- Human review on every asset before launch
- C2PA Content Credentials embedded on output where supported
- Disclosure label on any ad depicting a real person, real voice, or real event
- Audit trail per asset: prompt, model version, consent record, edits applied
- Legal review on any voice clone or face swap of an identifiable person
The advertisers who win run synthetic media as a controlled production line, not a magic-button. Volume up. Cost down. Disclosure on. Trust intact.

Frequently asked questions
What counts as synthetic media?
Any image, video, audio, or text where a generative model produced or materially altered the asset. AI ad creatives qualify. So do voice clones, avatar talking heads, and deepfakes. A real photo with an AI background swap is synthetic. A real recording with an AI-cloned voiceover is synthetic. The label sits on the asset, not the campaign.
Is synthetic media legal in advertising?
Generally yes for commercial ads, with rules. The FTC requires that ads not be deceptive. The EU AI Act, Article 50, requires transparency labeling on synthetic image, audio, and video. Meta and Google require disclosure on ads about elections, politics, and social issues. Synthetic depictions of real people without consent invite right-of-publicity claims.
What is the difference between synthetic media and a deepfake?
Deepfakes are a subset of synthetic media. A deepfake specifically swaps a real person's face, voice, or likeness onto another body or recording. All deepfakes are synthetic media. Most synthetic media is not a deepfake. A text-to-video clip of an invented character is synthetic, not deepfaked.
Do I need to disclose AI use in ads?
Disclose when a reasonable viewer would mistake the content for a real recording of a real person or event. Meta and Google require it for political and social-issue ads. The EU AI Act requires it broadly for synthetic image, audio, and video. Many brands now add a small AI-generated tag on every synthetic ad as a safe default.
How do I prove an asset is synthetic or authentic?
Use C2PA Content Credentials. The standard, backed by Adobe, Microsoft, OpenAI, and Google, embeds a tamper-evident manifest in the file. It records the model used, the edits applied, and the publisher. Platforms like LinkedIn and TikTok now read and surface these credentials on uploaded media.
