Seedance 2.0: AI Video That Takes
Everything You Give It.
Seedance 2.0is ByteDance's multimodal AI video generation model. Where most models accept a prompt or a single image, Seedance 2.0 accepts up to 9 images, 3 video clips, and 3 audio files alongside your text — generating up to 15 seconds of cinematic video with native dual-channel stereo audio in a single pass.

What Makes Seedance 2.0 Different?
Seedance 2.0 is built around a unified multimodal architecture that treats text, images, video, and audio as equal inputs. Most AI video models have one primary input and tolerate the others. Seedance 2.0 was designed from the start to reason across all four simultaneously — which is what makes the reference-to-video mode work at the quality it does.
The practical effect: you can hand the model a character reference image, a motion reference clip, an audio tone reference, and a text description of the scene — and it will synthesize all of them into a single coherent output, with audio generated natively alongside video in dual-channel stereo. At up to 15 seconds per generation, it also gives you more runtime per clip than most competing models.
Four Capabilities That Define Seedance 2.0
Each one reflects the core design principle: all media types are first-class inputs.
Reference-to-Video
Combine up to 9 images, 3 video clips, and 3 audio files with your text prompt. Images anchor visual identity, video clips guide motion, and audio files inform the sonic feel — all synthesized into one coherent output.
Native Stereo Audio
Dialogue, sound effects, music, and ambient sound are generated alongside the video in dual-channel stereo — no post-production audio step required. Can be disabled for silent output.
Camera & Scene Control
Describe camera movements, lighting conditions, shadow behavior, and scene composition in your prompt. Seedance 2.0 treats these as direct production instructions, not loose aesthetic suggestions.
Up to 15 Seconds
Generate clips from 4 to 15 seconds in a single pass. The longer ceiling matters for multi-shot sequences: more runtime per generation means fewer clips to assemble in post, and fewer consistency breaks at cut points.

How to Generate Video with Seedance 2.0
From prompt to finished clip with synchronized audio in four steps.
Choose your generation mode
Start from a text prompt alone, upload a single reference image for image-to-video, or supply multiple images, video clips, and audio files for reference-to-video generation.
Write your prompt & add references
Describe the scene, camera movement, and mood. Add up to 9 images, 3 video clips, and 3 audio files to lock visual style, motion patterns, and audio feel across the generation.
Set resolution, aspect ratio & duration
Choose from 480p, 720p, or 1080p across six aspect ratios. Set a clip length between 4 and 15 seconds — the longer range lets you fit multi-shot sequences in a single generation.
Generate & download
Seedance 2.0 renders video with synchronized dual-channel stereo audio in one pass. Preview and download when ready — no post-production audio work required.
