Cinema-Grade Digital Human Tutorial: Build Your 24/7 Digital Twin in 3 Steps!
As AI technology rapidly evolves, the most lifelike digital humans have arrived. With just one photo and 30 seconds of audio, HeyGen’s newly launched Avatar IV model creates AI avatars that surpass human actors in realism. This breakthrough leverages a diffusion-based audio-driven facial engine, syncing nuanced expressions—pauses, nods, tonal shifts—to speech rhythm, emotion, and semantics. It supports profile shots and multi-angle dynamics for cinematic immersion, generating full-body, half-body, or portrait formats for diverse scenarios. Beyond humans, it animates static illustrations, comics, and even pets with emotional fidelity.
Simplified Workflow:
- Upload a selfie or AI-generated portrait.
- Input text (speech, song lyrics) or upload voice audio.
- Generate an HD video where your digital twin speaks exactly like you.
