Seedance v1.5 Pro Text-to-Video
Native audio-visual joint generation model by ByteDance. Supports unified multimodal generation with precise audio-visual sync, cinematic camera control, and enhanced narrative coherence.
What it does
Seedance v1.5 Pro Text-to-Video, 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.
A cinematic, ultra-realistic underwater scene of a majestic whale swimming gracefully through the deep blue ocean. Sunlight rays penetrate the water from above, creating soft volumetric light beams. The whale’s massive body moves slowly and smoothly, with gentle tail motions and flowing fins. Tiny air bubbles and floating particles drift through the water. Surrounding marine life appears subtly in the distance, enhancing the sense of scale. Natural ocean colors, realistic water caustics, calm and peaceful atmosphere. Smooth camera tracking alongside the whale, shallow depth of field, IMAX-qual
