Seedance 2.0 AI is an advanced multimodal AI video generation platform that turns text, images, audio, or video inputs into cinematic-quality 15-second videos with physics-based audio and consistent characters. It is the latest model in the Seedance family, developed by ByteDance, and runs on a cloud-based service accessible via web browser.
What is Seedance 2.0?
Seedance 2.0 is an AI video generator that converts text prompts up to 800 characters, images, audio files, or reference videos into coherent 15-second cinematic videos at up to 2K resolution and 24 FPS. It supports up to 12 reference files per generation and includes physics-based audio synthesis, multi-shot narrative structures, and character consistency across frames via its World ID technology. The platform is hosted on ByteDance’s infrastructure and accessible through a web interface or RESTful API.
Key Features
- Acoustic Physics Fields — Industry-first technology that generates audio as part of the scene, with sound reacting physically to materials (e.g., footsteps on marble vs. carpet, cathedral reverb). No post-production audio needed.
- World ID Character Lock — Ensures character identity (face, outfit, proportions) remains consistent across every frame and multiple shots in a single generation, solving the common AI video inconsistency problem.
- World-MMDiT Architecture — Built on a physics-aware architecture that models gravity, collision, and inertia, resulting in realistic motion and scene interactions at 24 FPS.
- Multi-Shot Cinematic Narratives — A single prompt is automatically decomposed into multiple shots (wide, close-up, tracking, dramatic reveal) with transitions and pacing, producing a structured story rather than an isolated clip.
- Multimodal Input — Accepts text, image, video, and audio inputs (up to 12 files combined) for flexible creation including text-to-video, image-to-video, video-to-video, and reference-guided generation.
- 2K Resolution & 15-Second Duration — Outputs videos from 4 to 15 seconds at up to 2K resolution (2560x1440) with Enhanced Temporal Attention for consistent quality throughout. Supports 6 aspect ratios: 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1.
- Node-Based Creative Control — Offers real-time preview and advanced controls for professional camera direction, including extend, in-paint, character swap, and audio remix editing capabilities.
Who is it for?
- Content Creators — Generate viral short-form videos for TikTok, Instagram, and YouTube at scale, with recurring characters maintained via World ID across content series.
- Marketers & Brands — Produce 10+ ad variants from a single product image, reducing video production costs by 30–50%, with API integration for automated ad generation across platforms.
- Filmmakers & VFX Artists — Generate pre-visualization sequences from text descriptions in minutes, maintaining character identity across 20+ shots with World ID, and using node-based controls for professional camera direction.
- Educators & Trainers — Create animated explainer videos with synchronized narration, transform lesson concepts into vivid visual content, and generate multi-language versions by changing the prompt language.
- Developers — Integrate AI video generation via RESTful API with elastic cloud computing for auto-scaling, and connect with automation tools like n8n and CapCut.
- E-commerce Businesses — Generate product showcase videos, virtual tours, and personalized AI avatars from static product images, turning them into dynamic video ads in seconds.

FAQ
What is Seedance 2.0?
Seedance 2.0 is a ByteDance-developed AI video generator that creates 15-second cinematic videos from text, images, audio, or video inputs, featuring physics-based audio, multi-shot narratives, and consistent characters.
What's the difference between Seedance 2.0 and Seedance 1.5 Pro?
Seedance 2.0 offers 2K resolution (vs. 1080p), native multi-shot narratives with transitions (vs. partial), Acoustic Physics Fields for synchronized audio (vs. basic lip-sync), World ID character lock (vs. improved), and physics simulation (vs. basic). It supports up to 15 seconds and 12 input files.
It supports text (up to 800 characters), images, videos, and audio files. You can combine up to 12 reference files in a single generation, including options for text-to-video, image-to-video, video-to-video, and reference-to-video.
What resolutions and aspect ratios does Seedance 2.0 offer?
Output resolutions up to 2K (2560x1440) at 24 FPS, with 6 aspect ratios: 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1. Video duration ranges from 4 to 15 seconds.
How does the Acoustic Physics Fields feature work?
Audio is generated as an integral part of the scene, with sound behavior determined by physical context—e.g., footsteps change texture based on surface material, and dialogue echoes in large spaces. No external audio editing is required.
