What it does
Seedance v1.5 Pro Image-to-Video Fast, in practice.
Seedance 1.5 PRO is a foundational model engineered specifically for native joint audio-visual generation, developed by the ByteDance Seed team. It represents a significant leap forward in transforming video generation into a practical, utility-driven tool. By integrating a dual-branch Diffusion Transformer architecture, the model achieves exceptional audio-visual synchronization and superior generation quality, establishing it as a robust engine for professional-grade content creation.
- Unified Multimodal Generation : Leverages a unified framework based on the MMDiT architecture to facilitate deep cross-modal interaction, ensuring precise temporal synchronization and semantic consistency between visual and auditory streams.
- Precise Audio-Visual Sync : Achieves high-fidelity alignment of lip movements, intonation, and performance rhythm. It natively supports multiple languages and regional dialects, accurately capturing unique vocal prosody and emotional tonalities.
- Cinematic Camera Control : Possesses autonomous camera scheduling capabilities, enabling the execution of complex movements such as continuous long takes and dolly zooms ("Hitchcock zoom"), significantly enhancing the dynamic tension of the video.
- Enhanced Narrative Coherence : Through strengthened semantic understanding, the model significantly improves the overall narrative coordination of audio-visual segments, providing strong support for professional-grade content creation.
- Efficient Inference Acceleration : An optimized multi-stage distillation framework, combined with quantization and parallelization, boosts the end-to-end inference speed by over 10x while preserving high performance.
- Film and Short Drama Production: Creating high-quality, emotionally resonant scenes with precise character performances.

Sample prompt
The prompt behind the sample.
Use the provided image as the first frame. On a quiet residential street in a summer afternoon, a young girl in high-quality Japanese anime style slowly walks forward. Her steps are natural and light, with her arms gently swinging in rhythm with her walk. Her body movement remains stable and well-balanced. As she walks, her expression gradually softens into a gentle, warm smile. The corners of her mouth lift slightly, and her eyes look calm and bright. A soft breeze moves her short hair and headband, with individual strands subtly flowing. Her clothes show slight natural motion from the wind.
