Seedance 2.0 is an AI video generation platform from ByteDance that accepts text, images, video, and audio inputs to produce cinematic video sequences with consistent multi-shot storytelling and audio synchronization.
What is Seedance 2.0?
Seedance 2.0, developed by ByteDance, is a multimodal video generation model that converts text descriptions, still images, reference videos, or audio clips into high-quality cinematic videos. It runs as a web-based platform (seedancetwo.com) and supports up to 12-second 1080p video output. The model leverages ByteDance's AI technology to understand prompts and replicate visual styles, character appearances, camera motions, and audio rhythms from reference materials.
Key Features
- Multimodal Input — Accepts text, image, video, and audio as source material; any combination can serve as reference for motion, style, characters, or sound.
- Reference Image — Precisely reproduces composition, character details, and visual style from a provided image.
- Reference Video — Replicates camera movements, motion rhythms, and creative effects from a reference video clip.
- Video Extension — Smoothly extends and connects shots to produce continuous scenes guided by text prompts (described as "keep shooting").
- Video Editing — Allows targeted edits to specific segments of existing videos without regenerating the entire clip (e.g., swap characters, remove or add elements).
- Overall Consistency — Maintains character faces, outfits, text, and style across multiple shots; fixes common issues like inconsistent camera work and scene jumps.
- Audio Synchronization — Supports music beat sync (audio beats align with on-screen actions) and natural voice timbre for dialogue and narration.
- Long Take Smoothness — Produces long shots with natural scene transitions and no breaks, with enhanced continuity.
