Seedance 2.0 Overview

Seedance 2.0 is ByteDance's latest AI video generation model — available exclusively on BigMotion. It's the world's first quad-modal video generation model, accepting text, images, video, and audio as input. The result is a level of creative control that no other AI video tool currently offers.

What Makes Seedance 2.0 Different

Most AI video models only accept text or images as input. Seedance 2.0 accepts all four: text, images, video clips, and audio — and can use them simultaneously. This means you can describe a scene in text, reference a character's face from a photo, match the camera movement from an existing clip, and sync the output to a music beat — all in a single generation.

Core Capabilities

Text-to-Video

Generate videos from detailed text descriptions. Describe your subject, motion, scene, camera movement, and style — and Seedance 2.0 brings it to life with cinematic quality.

Image-to-Video

Animate any static image into a dynamic video. Upload a reference photo to lock in visual style, character appearance, or scene composition.

Video-to-Video

Transform or extend existing video clips. Use a reference video to recreate specific camera movements, motion rhythms, or visual effects.

Audio-Driven Generation

Upload a music track or audio clip and let Seedance 2.0 generate a video that syncs to the beat, mood, and rhythm automatically.

Native Audio Output

Seedance 2.0 generates sound alongside video — dialogue, sound effects, and music scoring — with accurate lip-sync and realistic environmental audio.

Up to 2K Resolution

Output up to 2K resolution with hyper-realistic physical dynamics, smooth motion, and consistent style across the full duration.
