Key Innovations

1. Dataset and Captioning

Seedance 1.0 is trained on a large-scale, multi-source bilingual dataset paired with dense video captions. This enables precise understanding of complex prompts and improves semantic alignment across varied scenarios, styles, and motion dynamics.

2. Unified Diffusion Transformer Architecture

The model employs a decoupled spatial-temporal attention design within a multi-modal diffusion transformer:

• Spatial layers focus on per-frame fidelity and compositional detail.
• Temporal layers ensure coherent motion trajectories and stable multi-shot transitions.
  

3. Video-Specific RLHF

Seedance 1.0 integrates a multi-dimensional reward framework:

• Foundational reward model improves image-text alignment and structure.
• Motion reward model enhances motion plausibility and temporal smoothness.
• Aesthetic reward model optimizes for perceptual quality using keyframe-based evaluation.

This cascaded RLHF approach improves prompt following, motion realism, and visual fidelity simultaneously.

4. Inference Acceleration

A multi-stage distillation framework and kernel-level optimizations enable 10× faster inference without compromising output quality:

• Multi-stage distillation framework uses techniques like Trajectory-Segmented Consistency Distillation (TSCD) and scores distillation to minimize diffusion steps, achieving faster inference without quality loss.
• Kernel-level optimizations applies fused GPU kernels, quantization, and memory-efficient scheduling to maximize throughput and reduce latency during video generation.
