Flow matching diffusion transformer model

About Fable 2

Fable 2 is a unified multimodal Flam generation model built on a flow matching diffusion transformers with support for image, audio and video as reference

Transform an idea into immersive visuals with exceptional motion stability, audio generation & full control over transparency, lighting, shadow and camera movement.

Cinema-Grade
Transparency

Video models produce opaque, flat footage. Our dual-decoder architecture treats color and transparency as inseparable creative decisions. Its trained with edge-aware supervision to produce the crisp, compositable boundaries, and fine-tuned on curated datasets emphasizing dynamic motion, fine structural detail, and strong foreground presence

The Science of Compositing

Dual-Decoder Architecture

Dual-Decoder Architecture

Color and alpha channels are processed together. Ensures temporal consistency across frames without any flicker

Edge-Aware Precision

Edge-Aware Precision

Output smooth boundaries between transparent and opaque objects, no jagged edges

Optimized alpha channel

Optimized alpha channel

Produce alpha value between 2 to 98 percent with natural light blending. Easily create transparent particle and fluid effects
