Seedance 2.0.
Cinema in Every Frame.
The first unified multimodal director.
Text, image, audio, and video in one seamless pass.
Seedance 2.0 is a video generation model from ByteDance that turns a text prompt, plus optional images, video clips and audio, into cinematic clips of 4 to 15 seconds, with dialogue, sound effects and music generated in the same pass. On Segmind it runs through one API key, from 480p drafts to 4K finals, at $0.1512 per second for 720p (as of 13 Oct 2026).

Agency Workflow
Brief to cinematic ad.
In minutes, not months.
Resource Ingestion
Upload. Reference. Ground.

Reference up to 9 style images + 3 character references. Your IP, your aesthetic. Always.
PNG, MP4, MP3 · up to 12 files
Narrative Planning
Directorial Intelligence.
One prompt. Multiple coherent shots: wide establishes, medium interactions, dramatic close-ups.
"A girl travels through the worlds of famous paintings" → automatically partitioned into 8 distinct, consistent shots.
Rapid Iteration
20+ variations. One morning.
A/B test hooks, emotional tones, and localized audio tracks at machine speed. Real-time iteration replaces the days-long revision cycle.
Different hooks, different markets, different languages, generated in parallel. Always-On Content Engine.
Use Cases
One model.
Infinite applications.
Cinematic brand spots in minutes
Generate campaign-ready hero ads with consistent brand identity, character lock, and native audio. No studio required.
Scroll-stopping short-form content
Create platform-native videos for TikTok, Reels, and Shorts: high-energy, visually striking content that captures attention in the first frame.
Cinematic product reveal videos
Turn a brief or image into a polished product demo, with dramatic lighting, motion, and atmosphere that makes every launch feel premium.
Multi-scene cinematic stories
Compose multi-shot narratives with identity continuity across scenes: one character, infinite worlds.
Shoppable video at catalogue scale
Generate thousands of on-brand product videos from imagery and briefs: each unique, each conversion-ready, at catalogue speed.
Dynamic action content at scale
Produce high-energy sports and lifestyle videos that capture peak moments, athleticism, and brand personality. No crew required.
Under the Hood
Built different.
Architecturally speaking.
Spatiotemporal Tokenization
The model encodes video as 3D patches, not flat frame sequences. This enables superior motion coherence and true object permanence across cuts.
Physics-Aware Objectives
Training penalizes physically impossible motion: floating hair, melting objects, impossible shadows. Gravity and fluid dynamics behave realistically.
Multimodal Context Window
Text, image, audio, and motion references are fused into a single context before decoding begins, ensuring coherent cross-modal alignment.

Frequently asked questions
What is Seedance 2.0?
Seedance 2.0 is ByteDance's multimodal video generation model. It turns a text prompt, plus optional images, video clips and audio, into cinematic clips of 4 to 15 seconds and generates dialogue, sound effects and music in the same pass. Segmind runs Seedance 2.0 through a pay-as-you-go API.
How much does Seedance 2.0 cost on Segmind?
Seedance 2.0 costs $0.1512 per second for a 16:9 clip at 720p on Segmind, so a 5-second clip costs about $0.76 (as of 13 Oct 2026). 480p costs $0.0703 per second, 1080p $0.34 and 4K $1.3721. Turning on audio does not change the price.
Can Seedance 2.0 generate audio?
Yes. Seedance 2.0 generates dialogue, sound effects, ambience and music together with the picture, so sound and motion stay in sync. Audio is on by default, and setting generate_audio to false gives a silent clip at the same price.
What references can I give Seedance 2.0?
Seedance 2.0 accepts up to 9 reference images, 3 reference videos of 2 to 15 seconds each and 3 audio files in one request. Cite them in the prompt as image 1, video 1 or audio 1. You can instead set a first frame, and optionally a last frame, for image to video.
How long and how sharp can Seedance 2.0 videos be?
Seedance 2.0 generates clips of 4 to 15 seconds at 480p, 720p, 1080p or 4K (3840x2160), in 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 or an adaptive aspect ratio. Draft at 480p and render finals at a higher resolution.
How do I make a multi-shot video with Seedance 2.0?
Write the shots into one Seedance 2.0 prompt as Shot 1:, Shot 2: and so on, describing the framing, camera move and action for each. Seedance 2.0 renders them as one clip, cutting from shot to shot. Add reference images to keep a character's look the same in every shot.
What is the difference between Seedance 2.0 and Seedance 2.0 Fast?
Seedance 2.0 Fast is about 20% cheaper and returns sooner, at $0.1210 per second for 720p (as of 13 Oct 2026), but it outputs 480p or 720p only. Seedance 2.0 adds 1080p and 4K. Use Fast for drafts and high volume, and Seedance 2.0 for final renders.
