RealFace

A Breakthrough Approach to Authentic Lip Sync

The first AI video solution to precisely align lip movements, expressions, and scene dynamics, without compromising the video’s visual and emotional integrity.

Multimodal Understanding of Faces

RealFace was built from the ground up to deeply understand on-screen faces and faithfully adapt them. With full-scene awareness, it delivers frame-accurate lip sync and expression transfer across languages.

Built for Real-World Complexity

Unlike avatar‑based models that falter when scenes get complicated, our system preserves visual integrity across multiple speakers, rapid movement, shifting light, and changing camera angles.

Preserves Speaker Identity and Style

Our model faithfully retains person-specific gestures, micro-expressions, and mouth movements, ensuring that the speaker’s emotional presence and authenticity carry through, no matter the language.

Highly Efficient Architecture 

The model is optimized for performance, with under 1B parameters and minimal overhead, achieving ~10x real-time generation on standard GPUs like a single NVIDIA A10.

AI Lip Sync That Solves Real-World Video Challenges

Facial structures & expressions

Our Geometric Face Engine constructs a speaker‑specific 3‑D mesh and phoneme‑aligned motion vector, re‑animating even the smallest micro‑expressions with precision.

Linguistic variations and person-specific styles

Our Context‑Aware Speech Encoder extracts timed phonemes and syllables, then blends them with speaker‑specific motion codebooks so lip movements follow the target language’s rhythm.

Lighting and resolution issues

Our Latent Appearance Fusion Attention module fuses speaker samples into a rich texture embedding, preserving original lighting, even in low light or shifting conditions, and maintaining the native grain and resolution of the footage.

Camera angles and head turns

Our Geometric Face Encoder disentangles micro-expressions and pose information, creating a model that generalizes well into extreme angles. This significantly outperforms avatar-based solutions that rely heavily on precise geometric representations.

UGC-style editing

Our Temporal Reorientation module maintains visual and motion consistency across jump cuts by tracking facial geometry frame-by-frame, rather than relying on continuous footage. Designed for fast-paced edits, it instantly re-establishes sync—preserving lip alignment without visual drift.

Multiple speakers

Our Advanced Video Analysis AI isolates and tracks every speaking face, extracting a comprehensive visual representation of each speaker across angles, sizes, and expressions
