Talking video
Cinematic talking video from a single portrait
Most advanced model for realism and expressiveness. Portrait in, video out.
Cinematic realism
Sharp detail, stable lighting, fewer artifacts — tuned for faces and close-ups.
Expressive performance
Micro-expressions and emotion matched to the voice, not just the mouth.
Long-video consistency
Holds identity and detail across minutes — no drift, no frame-to-frame pop.
No GPU, no studio
One portrait + script. Cloud rendering, no GPU, no on-set capture.

Technical details
Diffusion-based realism
Refines each frame step by step — clearer skin and lighting, natural micro-expressions, fewer artifacts.
Coarse-to-fine generation
Locks performance first (timing, mouth, head motion), then refines detail (skin, eyes, lighting) — better quality, less render time.
