What Is Synthetic Media?

Synthetic media is the umbrella term for any media content that has been generated, substantially altered, or composed using artificial intelligence. This includes AI-generated video (digital twin performances, avatar content), AI-synthesized audio (voice clones, text-to-speech), AI-created images (synthetic faces, generated artwork), and AI-written text. Synthetic media is distinct from traditional media production, where content is captured from real-world events and people through cameras, microphones, and human writing.

The synthetic media category encompasses both authorized commercial applications — digital twin content, AI avatar videos, voice-cloned podcasts — and unauthorized malicious uses — deepfakes, identity theft, disinformation. The critical distinction is consent and provenance. Authorized synthetic media is created with the knowledge and permission of the person being represented and carries verifiable provenance metadata. Unauthorized synthetic media is created without consent and typically lacks attribution. The entire AI digital identity market is, fundamentally, the commercial synthetic media industry.

Key Characteristics

  • AI generation: Synthetic media is produced by generative AI systems — diffusion models, GANs, voice synthesis models, large language models — rather than by traditional recording equipment.
  • Identity replication: Much synthetic media involves replicating the visual appearance, voice, or behavioral characteristics of a real person, making identity rights a central legal concern.
  • Scalable production: Unlike traditional media, synthetic media can be produced at near-zero marginal cost and at speeds measured in seconds rather than hours or days.
  • Quality convergence: The quality of synthetic media has converged with traditionally produced media to the point where human viewers often cannot distinguish between them.
  • Provenance challenge: Without embedded provenance metadata, there is no inherent way to determine whether media is real or synthetic, creating trust and verification challenges.

Why It Matters

Synthetic media is the product category that AI digital identity companies sell. HeyGen sells synthetic video. ElevenLabs sells synthetic audio. Soul Machines sells synthetic interactive experiences. Understanding synthetic media as a unified category — with both enormous commercial potential and significant risks — is essential for navigating the AI digital identity landscape. The companies that succeed will be those that produce high-quality synthetic media while implementing robust provenance and consent frameworks.
