Seedance 2.0: Multi-Modal AI Video Generator by ByteDance

Seedance 2.0 by ByteDance is built on a Dual-Branch Diffusion Transformer (DB-DiT) architecture that jointly generates synchronized audio and video in a single pass — not as separate steps bolted together. Combine up to 9 images, 3 videos, and 2 audio clips as creative references. The model understands composition, camera language, motion rhythm, and sound characteristics from your inputs to produce cinematic results with realistic physics simulation, character consistency, and multi-shot narratives — all within a single 4-to-15 second generation.

Step 1: Upload Reference Media

Upload your creative references — up to 9 images, 3 video clips, and 2 audio files. Seedance 2.0's multi-modal engine can reference composition, motion, camera movement, and sound characteristics from your inputs simultaneously, giving you fine-grained control over the generation process.

Step 2: Describe & Configure Settings

Write a prompt describing your desired video. Use @ mentions to specify how each reference should be used. Choose from 6 aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 21:9), durations from 4 to 15 seconds, Pro or Fast mode, and resolution up to 1080P for the perfect output.

Step 3: Generate & Download

Click generate and let Seedance 2.0 create your video with native audio-video joint generation. Download your MP4 video — Pro mode delivers maximum quality with precise prompt adherence, while Fast mode enables rapid creative iteration at lower cost.

Multi-Modal Reference Input

Go beyond text-only prompts. Seedance 2.0 accepts images, videos, and audio files simultaneously as creative references. Upload a video to replicate its camera movements, an image to define character appearance, or audio to guide the soundtrack — then combine them freely. The @ mention system lets you specify exactly how each input should be used, breaking the material boundaries of conventional video generation.

Native Audio-Video Joint Generation

Unlike other AI video tools that generate audio separately, Seedance 2.0 produces synchronized audio and video in a single pass. The result: natural dialogue with phoneme-level lip sync, contextually appropriate sound effects, and music that follows the narrative rhythm — all generated together for seamless audiovisual coherence.

Character Consistency & Physics Simulation

Upload a single reference photo and Seedance 2.0 preserves facial features, clothing, and character style throughout the entire video — even during 360° head turns and dramatic lighting changes. The physics-based world modeling simulates realistic cloth, fluids, hair, and smoke dynamics, delivering natural motion across complex scenes.

Flexible Output: 6 Ratios × 12 Durations × 3 Resolutions

Customize every aspect of your output. Choose from 6 aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 21:9), continuous durations from 4 to 15 seconds, and 3 resolution tiers (480P, 720P, 1080P). Pro mode delivers maximum quality for final production; Fast mode enables quick creative iteration. All videos are delivered in MP4 format ready for any platform.

Short Film & Cinematic Storytelling: Leverage Seedance 2.0's multi-shot narrative capability to produce edited sequences with natural cuts and transitions in a single generation. Upload reference videos for camera movements and character images for consistency — create concept films, music videos, and cinematic content that feels professionally produced without expensive equipment or crews.

Marketing & Product Advertising: Transform static product photos into high-impact video ads with native audio. Seedance 2.0's Pro mode at 1080P resolution produces campaign-ready assets for social media, landing pages, and digital advertising. Use reference videos to replicate proven ad formats, or let the AI generate fresh creative with cinematic quality and synchronized soundtrack.

Social Media & UGC Content: Create platform-optimized content with the right aspect ratio for every channel — 9:16 for TikTok and Reels, 16:9 for YouTube, 1:1 for feeds. Fast mode enables rapid iteration to test multiple creative concepts. The multi-modal input lets you combine trending audio with your images for viral-ready content that stands out.

Action & VFX Sequences: Seedance 2.0's physics simulation engine handles complex dynamics — realistic cloth, fluids, hair, explosions, and smoke. Combined with precision camera control (pan, tilt, zoom, roll, dolly zoom), you can create action sequences and visual effects that would require a full production team and post-processing pipeline using traditional methods.
