Comparison with Other Models

vs Google Veo 3: Seedance offers faster inference speeds and better multi-shot storytelling with seamless scene continuity, while Google Veo 3 focuses more on creative style transfer but has limited multi-shot support. Seedance delivers more realistic motion and prompt adherence compared to Veo 3's stylized outputs.

vs Runway: Seedance provides higher cinematic quality and advanced motion control optimized for multi-shot narratives, whereas Runway is often geared towards post-production editing and stylization with less emphasis on video generation speed. Seedance is better suited for rapid prototyping and batch workflows.

vs Sora: Seedance emphasizes consistent multi-shot video generation with realistic lighting and motion, while Sora focuses more on video editing and effect application rather than generation speed. Seedance offers stronger prompt fidelity and scene continuity for storytelling.

vs Kling: Seedance excels in fast, high-quality video synthesis with controllable settings for framing and camera moves, whereas Kling is generally used for stylization and video enhancement rather than native generation. Seedance supports longer multi-shot sequences with cinematic realism, which Kling lacks.
