Seedance 2.0 Guide: Multimodal AI Video Creation System

What Is Seedance 2.0 and Why It Matters

Seedance 2.0, developed by ByteDance, represents a fundamental shift in AI video generation. Unlike previous models that rely on a single text prompt or one reference image, Seedance 2.0 accepts images, videos, audio, and text simultaneously as inputs. This multimodal approach lets you direct every visual, auditory, and narrative aspect of your creation with a level of control that was previously impossible in generative video.

The core differentiator is the reference system. You can set visual style with an image, specify motion and camera work with a video, drive rhythm with audio, and guide narrative with text. The result is a production-grade tool that behaves less like a prompt-based generator and more like a virtual film set.

However, the same tool used by different creators produces vastly different results. The key? Camera movement literacy. Most users only describe scene content but ignore how the camera moves. This Seedance 2.0 guide covers both the multimodal reference system and the complete camera movement vocabulary you need to extract professional results.

Seedance 2.0 Technical Specifications

Before diving into workflows, here are the hard limits you need to know:

Practical tip: With a 12-file limit, prioritize assets that have the greatest impact on your output—whether that's a reference video for motion or an image for character consistency.

The Multimodal Reference System

Seedance 2.0 uses an @ mention system to specify how each uploaded asset contributes to the generation. This is the mechanism that separates basic prompting from professional-grade direction.

Entry Points

First/Last Frame Mode: Use when you only need a starting image plus a text prompt. Simple and effective for single-shot generation.

Universal Reference Mode: Use for multimodal combinations (images + videos + audio + text). This is where the real power lies.

The @ Syntax

After uploading files, reference them in your prompt using @ followed by the file identifier:

@Image1 as the first frame, reference @Video1 for camera movement, use @Audio1 for background music

Reference Patterns

These are the standard instruction patterns for telling Seedance 2.0 what to extract from each file:

Key principle: Use natural language to describe what you want to reference. Be explicit about which element (motion, style, camera, character) should be extracted from which file.

Core Capabilities

1. Enhanced Base Quality

Seedance 2.0 delivers significant improvements in fundamental generation quality: physics accuracy (objects fall, collide, and interact according to real-world rules), fluid motion with proper momentum and timing, precise instruction following for complex prompts, and consistent visual style throughout the video.

Example prompt:

A girl elegantly hanging laundry, finishing one piece and reaching into the basket for another, shaking it out firmly.

The model handles continuous action, fabric physics, and natural body mechanics without explicit guidance.

2. Multimodal Reference System

This is the defining feature. You can reference motion patterns from videos, visual effects and transitions from creative templates, character appearances from images, camera techniques from cinematographic examples, and audio rhythm from music tracks. Combine these in a single prompt for full directorial control.

3. Character and Object Consistency

Previous models struggled with maintaining identity across frames. Seedance 2.0 addresses this with face consistency, product detail preservation (logos, text, fine details), scene coherence, and style lock that prevents visual drift during generation.

Example: Character reference combined with scene composition in a single generation.

Example prompt:

Man @Image1 comes home tired from work, walks down the hallway slowing his pace, stops at the front door. Close-up of his face as he takes a deep breath, adjusts his expression from stressed to relaxed. He enters and his daughter and pet dog run to greet him with a hug. The interior is warm and cozy.

4. Motion and Camera Replication

Upload a reference video and Seedance 2.0 can extract and apply complex choreography (fighting sequences, dance moves), camera techniques (dolly shots, tracking, crane movements), editing rhythm (cut timing, pacing), and special movements like Hitchcock zooms, whip pans, and orbit shots.

Example: Motion replication from a reference video applied to a generated character in an action scene.

Example prompt:

Reference @Image1 for the man's appearance in @Image2's elevator setting. Fully replicate @Video1's camera movements and the protagonist's facial expressions. Hitchcock zoom when startled, then several orbit shots inside the elevator. Doors open, tracking shot following him out.

5. Creative Template Replication

Beyond motion, you can replicate entire creative concepts: advertising formats (product reveals, lifestyle montages, brand stories), visual effects (particle systems, morphing, stylized transitions), film techniques (opening sequences, title cards, dramatic reveals), and editing styles (music video cuts, documentary pacing, commercial rhythm).

Example: Animation style template applied to generate new characters in a familiar visual format.

Example prompt:

Replace the person in @Video1 with the girl in @Image1. Replace the moon goddess CG with an angel referencing @Image2. When the girl crouches, wings grow from her back. Wings sweep past camera for transition. Reference @Video1's camera work and transitions. One continuous shot throughout.

6. Video Extension

Extend existing videos while maintaining narrative coherence. Set your generation duration to match the desired extension length.

Example prompt:

Extend @Video1 by 15 seconds. Reference @Image1 and @Image2 for the character. Scene 1: Side shot, character bursts through fence on motorcycle, nearby chickens startled. Scene 2: Spinning stunts on sand, tire close-up then aerial overhead shot. Scene 3: Mountain backdrop, launch off slope, ad copy appears through masking effect.

7. Video Editing

Modify existing videos without regenerating from scratch. Capabilities include character replacement (swap one person for another while keeping the action), element addition/removal, style transfer, and narrative changes.

Example: Character replacement in an existing video while preserving original actions and scene.

8. Audio-Synchronized Generation

Seedance 2.0 generates videos with native audio and can sync to reference audio: lip-sync dialogue in multiple languages, sound effects matched to on-screen actions, background music following visual rhythm, and voice acting with emotional expression.

Example prompt:

Fixed shot. Fisheye lens looking down through circular opening. Reference @Video1's fisheye effect. Make the horse from @Video2 look up at the fisheye lens. Reference @Video1's speaking motion. Background audio references @Video3's sound effects.

9. Beat-Synced Editing

Create music-video-style content that hits the beats. Upload a music track as audio reference and images or videos to sync against the rhythm.

Example prompt:

Images @Image1 through @Image7 cut to the keyframe positions and overall rhythm of @Video1. Characters in frame are more dynamic. Overall style is more dreamlike. Strong visual impact. Add lighting changes between shots.

10. One-Take Continuity

Generate long, unbroken shots with consistent motion. This is critical for cinematic results.

Example prompt:

Spy thriller style. @Image1 as first frame. Front-facing tracking shot of woman in red coat walking forward. Pedestrians repeatedly block the frame. She reaches a corner, reference @Image2's corner architecture. Fixed shot as woman exits frame. A masked girl lurks at the corner, appearance references @Image3. Camera pans forward. She enters a mansion (@Image4). No cuts. One continuous take.

The Camera Movement System

Camera movement is the single most impactful variable in AI video quality. The same scene description, combined with different camera instructions, produces radically different results. Mastering this system is what separates amateur output from cinematic quality in Seedance 2.0.

Basic example: A boy walking through the forest produces a static, flat result. Adding smooth dolly follow, golden hour lighting transforms the same scene into a cinematic shot.

Level 1: Fundamental Camera Movements

These are the building blocks. If you are new to video prompting, start with Pan, Zoom, and Dolly — they cover 80% of basic requirements.

Level 2: Modifiers — Adding Emotion and Style

Camera movement is not just about direction. Modifiers add speed, emotion, and stylistic constraints that transform mechanical motion into storytelling.

Level 3: Combined Camera Movements

Combining two or more camera techniques creates complex visual effects. This is a core skill for advanced creators. Limit combinations to 2–3 movements per prompt and connect them with "+" or "while."

Prompt Optimization: From Basic to Master Level

Theory is useful, but seeing the progression from basic to professional prompts demonstrates the real impact of camera movement literacy.

Case Study: Forest Scene

Universal Prompt Template

Creative Applications

Advertising and E-commerce

Create product demonstrations with synchronized narration, lifestyle shots, and brand storytelling. The multimodal system lets you reference existing brand assets while generating new content. Upload your product images, a reference video for the desired editing style, and brand music for audio synchronization.

Content Localization

Generate multi-language video adaptations with native lip-sync. Reference the original video for motion while generating new dialogue in different languages. This reduces localization costs from full reshoot budgets to a single generation per language.

Storyboarding to Video

Convert static storyboard panels into animated sequences. Upload your boards as reference images and describe the motion between them. Each panel becomes a keyframe, and Seedance 2.0 interpolates the transitions.

Template-Based Creation

Find a video style you want to replicate, upload it as a reference, and generate new content in that style with your own characters and settings. This is particularly effective for social media content series that need visual consistency across episodes.

Best Practices

1. Be explicit about references. Write clearly which file is for what purpose. "Reference @Video1's camera movement" is significantly more effective than just mentioning the video.

2. Prioritize your uploads. With a 12-file limit, choose the assets that have the greatest impact. A reference video for motion typically matters more than a fourth reference image.

3. Double-check your @ mentions. With multiple files, verify that you haven't confused which image, video, or audio corresponds to which @ identifier.

4. Distinguish edit vs. reference. Make clear whether you want to edit an existing video (modify it directly) or use it as a reference (extract a quality from it for new content).

5. Align duration settings. When extending a video by 5 seconds, set the generation duration to 5 seconds. Mismatched durations produce inconsistent results.

6. Limit combined camera movements to 2–3. More than that creates conflicting instructions. Connect movements with "+" or "while" for clarity.

7. Use precise camera terminology. Avoid vague terms like "move." Instead, use "smooth 3-second dolly forward" with modifiers like "stabilized" or "gimbal shot."

8. Use natural language throughout. The model understands context. Describe what you want as you would to a human editor.
