Vidu Q4 Preview

Vidu Q4 Preview is a preview-stage video generation model developed by ShengShu Technology, introduced on October 7, 2026. Designed primarily for image-to-video and reference-to-video workflows, the model focuses heavily on expressive character performances, stable large motion, and native audio-visual synchronization.

Key Capabilities and Architecture

The model supports high-resolution outputs up to 4K with 10-bit color depth for smoother color gradients and richer visual fidelity. Rather than relying on standard text-to-video methods, Q4 Preview concentrates its capabilities on reference-guided generation, accepting up to 15 reference images and 3 audio voice references to maintain consistency across characters, wardrobes, and dialogues over clips lasting between 3 to 16 seconds.

Audio and Production Integration

A notable feature of Vidu Q4 Preview is its native generation of synchronized dialogue and sound effects directly aligned with the visual action. Positioned for professional and independent media production, the model aims to address common pitfalls in AI video creation, such as warped limbs during fast movement or loss of character identity across cuts.
