Seedances Introduction
Seedances is a next-generation AI video platform powered by ByteDance’s Seedance 2.0 model. It enables effortless creation of cinematic videos through text-to-video, image-to-video, and multimodal inputs — with native synchronized audio, realistic motion, physics simulation, director-level camera control, and high-fidelity 2K output.
Key Features

• Text-to-Video: Generate multi-shot cinematic clips from detailed prompts, with smooth motion, consistent characters, and natural storytelling.
• Image-to-Video: Animate photos into lifelike videos — characters move, express emotions, and interact while preserving identity and style.
• Multimodal Reference: Combine text + up to 9 images + 3 videos (≤15s) + 3 audio clips for precise control over motion, style, camera work, lighting, expressions, and sound.
• Motion & Performance Transfer: Replicate dance, actions, camera movements, or expressions from reference videos with high accuracy.
• Native Audio Generation: Produce synced dialogue (lip-sync), sound effects, ambient noise, music, and multilingual voiceovers.
• Output: Native 2K (up to 1080p/2K), smooth fps, multiple aspect ratios (vertical, widescreen, square).
  Core Advantages
• Unified audio-video joint generation for perfect synchronization and immersion.
