Seedance 2.5 is ByteDance's next-generation AI video generation platform that converts text, images, video clips, audio, and 3D references into production-grade 30-second native 4K films with synchronized audio.
What is Seedance 2.5?
Seedance 2.5 is an AI video generation platform built by ByteDance for production-grade content creation. It accepts text prompts, images, video clips, audio, keyframes, and reference assets as input, and outputs native 4K videos up to 30 seconds long with native audio-visual synchronization. It runs as a browser-based studio with text-to-video, image-to-video, and multi-reference-to-video modes, and supports up to 50 multimodal inputs in a single generation.
Key Features
- Native 30-second single segment — generates one continuous 30-second video instead of stitching multiple short clips, simplifying narrative pacing and camera direction.
- Up to 50 creative inputs — combines as many as 50 images, videos, and audio assets so the model can coordinate characters, products, locations, motion examples, sound references, and visual style.
- Unified multi-asset understanding — interprets multiple references together, keeping complex tasks controllable when the final video depends on several assets working in sync.
- High-quality video continuation — extends a shot with stronger continuity when a concept needs more time, motion, or story progression.
- Precision motion and audio-visual sync — production-grade camera movement control with native audio-visual synchronization for lifelike character dynamics and cinematic pacing.
- Controllable editing with visual consistency — follow-up edits from local changes to creative adjustments preserve subjects, scene logic, lighting, and style.
- Multimodal style reference — uploaded reference images or videos are analyzed and reused for visual style, color palette, and shot language.
- Multi-format export — outputs 4K MP4, GIF animations, and high-resolution cover images, with generation settings for aspect ratio (16:9), resolution (720p), duration (5s), AI audio, and output format.
Who is it for?
- Filmmakers and creative studios: produce 4K cinematic shots with controlled camera movement and synced audio for film and advertising work.
- Advertising and commercial teams: generate product and brand videos using reference assets to keep characters, products, and visual style consistent.
- Content creators and marketers: turn a written scene description into a finished 30-second video through conversational prompting.
- Multilingual creators: write prompts and subtitles in Chinese, English, Japanese, and other supported languages.
What can you do with Seedance 2.5?
- Text to video: describe a scene in the prompt box and generate a 4K video with cinematic composition and motion.
- Image to video: animate a still image into a photorealistic shot with controlled camera movement.
- Multi-reference to video: combine image, text, video, and audio references into a single cohesive film.
- Video continuation and remixing: extend an existing shot or remix content while preserving original motion and camera work.
How does Seedance 2.5 work?
Users open the browser studio, choose a mode (text-to-video, image-to-video, or multi-reference-to-video), and describe the video they want in a prompt of up to 30,000 characters. They can attach reference assets, select the Seedance 2.5 model, and set aspect ratio, resolution, duration, AI audio, and output format before generating. Generated videos can then be locally edited and remixed with follow-up adjustments.
