In the recent field of AI video generation, ByteDance (the parent company of TikTok) quietly released a new model called Seedance1.0, which has already outperformed Google's newly launched Veo3 in independent evaluations. Veo3 gained attention for its audio synthesis and cinematic tools, but Seedance1.0's technical prowess has been impressive, positioning itself as a leader in video generation.

The research paper for Seedance1.0 details the model's innovative features. ByteDance’s team achieved decoupling of spatial and temporal layers combined with multimodal positional encoding, enabling the model to handle both text-to-video and image-to-video generation tasks simultaneously. This approach supports complex scene transitions and multi-shot storytelling while maintaining consistent thematic expression.

Additionally, Seedance1.0's performance is supported by ByteDance's robust data pipeline. The team meticulously built a large-scale, multi-source dataset with detailed bilingual annotations and rich action and static feature labels to ensure accurate generated content. They also adopted a novel reinforcement learning setup with three reward models, focusing on foundational alignment, motion quality, and aesthetics.

In evaluations, Seedance1.0 outperformed Veo3 across multiple dimensions. In the SeedVideoBench benchmark test developed in collaboration with film directors, the model scored higher in following prompts and achieving motion realism. In image-to-video tasks, Seedance maintained visual consistency in input frames, whereas Veo3 experienced changes in lighting and texture in some cases.

In terms of inference performance, Seedance1.0 also excels. The model can generate a five-second 1080p video in 41.4 seconds, far surpassing other competitors like Sora, Runway Gen-4, and Veo3. ByteDance also noted significant progress in reducing costs and latency, moving closer to real-time video generation applications.

Seedance1.0 is planned to be integrated into platforms like Doubao and Jimeng by June 2025, aiming to significantly improve professional workflows and routine creative tasks. While Veo3 gained attention for its first combination of realistic videos with environmental sound effects and dialogue, Seedance1.0 shines more brightly in visual fidelity, motion stability, and narrative coherence, though it lags behind in audio capabilities.

Key Takeaways:

🌟 Seedance1.0 surpasses Google's Veo3, setting a new benchmark in video generation technology.  

⚙️ The model achieves complex scene transitions and multi-shot storytelling through multimodal positional encoding.  

⚡ Seedance1.0 performs excellently in generation speed and visual consistency, poised to become an important tool for professional creation in 2025.
