Seedance2.0

Seedance 2.0 is ByteDance's latest AI video generation model. It features a unified multimodal architecture that accepts text, image, audio, and video inputs to produce cinematic-quality videos with native audio, up to 2K resolution.

Seedance 2.0 supports quad-modal input: text prompts (natural language), images (up to 9 files), video references (up to 3 files, max 15s total), and audio files (up to 3 MP3s). You can combine up to 12 files across all modalities in a single generation.

Seedance 2.0 generates videos from 4 to 15 seconds in length with consistent temporal coherence. Multiple aspect ratios are supported including 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1.

Yes. Seedance 2.0 features native audio-video joint generation. It automatically creates context-aware sound effects and background music. It also supports beat sync with uploaded audio and lip-sync for dialogue scenes.

Director Mode gives you fine-grained control over performance, lighting, shadow, and camera movement. Combined with the World ID system that locks character identity across frames and shots, it enables multi-shot narrative creation with cinematic consistency.

Seedance 2.0 leads in motion stability, physics fidelity, and multimodal input support. It is the only model offering native quad-modal input with synchronized audio generation. Benchmarked on SeedVideoBench-2.0, it outperforms in instruction following, motion quality, and visual aesthetics.
