What it does
Avatar Omni Human 1.5, in practice.
Turn a single portrait photo into a lifelike, lip-synced talking video — driven entirely by an audio clip. Avatar Omni Human 1.5 (OmniHuman) by ByteDance is a state-of-the-art digital-human video generation model. Give it one reference image of a person and an audio track, and it generates a natural, expressive video of that person speaking — with accurate lip sync, head motion, and facial expressions that match the audio.
- Audio-driven lip sync — mouth movements precisely follow the speech in your audio.
- Identity preservation — the generated person stays faithful to your reference image.
- Natural motion — lifelike head pose, blinking, and micro-expressions, not a stiff talking head.
- Multilingual — works with audio in many languages, including Chinese, English, Japanese, Korean, Spanish, and Indonesian.
- High resolution — render output at up to 1080p.
