ByteDance OmniHuman: Complete Guide to AI Talking Head and Full-Body Video
Most video models generate a clip from text or an image. OmniHuman works differently: it takes a single image of a person and an audio track, and produces a video where that person appears to speak or perform in sync with the audio — with lip movements and body language driven by the audio’s meaning and cadence.
This makes OmniHuman especially useful for talking head and presenter workflows where you want a specific “person” (from one image) delivering content without filming.
What OmniHuman Does
OmniHuman can animate portraits, half-body, and full-body images from one input image:
- Lip sync driven by audio
- Facial expressions matching delivery tone
- Co-speech gestures and full-body motion (when the image includes the body)
- Support for photorealistic and stylized inputs
Inputs That Work Best
Image:
- Front-facing or slightly angled
- Clean lighting
- Face clearly visible
Audio:
- ElevenLabs TTS narration
- Recorded voice track
- Music track (for performance-style outputs)
Where OmniHuman Excels
- Full-body motion: naturalistic gestures when the source image includes the body
- Singing / performance: expressive motion synced to music
- Stylized characters: works on illustrations and cartoon styles
