Seedance 2.0 is ByteDance's audio-video generation model. One prompt yields a multi-shot clip up to 15 seconds with dual-channel audio. Text, image, audio, and video can all serve as inputs.
ByteDance's text-to-video model that ships sound with the frames
Seedance 2.0 is ByteDance Seed's video generation model, officially launched on 2026-02-12. It produces a single multi-shot clip up to 15 seconds long with dual-channel audio in one render. A Seedance 2.0 generation can take up to 9 reference images, 3 video clips, and 3 audio clips alongside the text prompt β so you can lock a character, match a soundtrack, or extend an existing shot without leaving the model. Seedance 2.0 emphasizes physical accuracy and multi-subject interaction: limbs land where they should, gravity and contact look right, and several characters can act in the same shot without floating-limb glitches.
A single Seedance 2.0 render outputs one continuous multi-shot clip up to 15 seconds β not a loop, not a stitch.
Seedance 2.0 renders dual-channel audio in the same pass as the frames β synced to the action.
Up to 9 images, 3 video clips, and 3 audio clips can join the text prompt to steer a Seedance 2.0 generation.
Seedance 2.0 handles multi-subject interactions β handshakes, dance partners, fights β without limb-drift artifacts.
Direct the lens move, the key light, the shadow shape β Seedance 2.0 takes shot-list vocabulary in the prompt.
Pass reference images and Seedance 2.0 keeps the same person or product across the Seedance 2.0 multi-shot.
Seedance 2.0 β text in, multi-shot video out, audio included.
You write the scene; Seedance 2.0 reads it and returns one continuous clip with multiple shots and synced sound. Product teasers, brand promos, social openers β output specificity tracks how detailed your prompt is.
A Seedance 2.0 prompt can combine all four modalities in one call.
Drop a reference photo to lock a character, an existing clip to extend, an audio track to match β Seedance 2.0 reads them together with the text. The official input cap is 9 images, 3 video clips, and 3 audio clips per generation.
Seedance 2.0 keeps limbs, contact, and timing right when several subjects share a shot.
Earlier video models broke when two people had to dance, fight, or shake hands β limbs slid, hands phased through, timing missed. Seedance 2.0 was specifically tuned for multi-subject physical interaction. Group choreography and contact-heavy scenes hold together at the shot level.
Seedance 2.0 produces dual-channel audio in the same pass as the video.
Legacy text-to-video tools shipped silent footage β you scored and mixed in post. Seedance 2.0 renders dual-channel audio synced to the on-screen action in one render, so a clip can land on TikTok or YouTube without a separate audio pass.
Seedance 2.0 takes shot-list vocabulary β dolly, crane, key light, shadow.
Brief the clip the way you'd brief a DP. Name the lens, the camera move, the key and rim light, the mood. Seedance 2.0 lands closer to the staged shot than guess-and-reroll β useful for hero cuts, brand promos, and openers.
Eight clips β each caption is a reusable Seedance 2.0 prompt

Four habits that separate usable footage from reroll noise
Name subject, camera move, lens, light, mood, and audio in one Seedance 2.0 prompt. A Seedance 2.0 render reflects what you give it.
16:9 for YouTube, 9:16 for Reels, 1:1 for feeds. 5-8s for loops, up to 15s for openers. Set both before you submit to Seedance 2.0.
Pass a reference photo when a character or product needs to look the same across shots. Seedance 2.0 reads up to 9 images per generation.
Say what you want to hear β 'ambient rain', 'upbeat lofi', 'two friends laughing'. Seedance 2.0 ships dual-channel audio in the same render, so describe it.
Each video model has its own strengths β realism, speed, style, cost
