Seedance 2.0 Complete Guide: Multimodal Video Creation

Seedance 2.0 represents a fundamental shift in AI video generation. Rather than relying solely on text prompts or single reference images, this model accepts images, videos, audio, and text as inputs—allowing you to direct every aspect of your creation like a true filmmaker.

The standout feature is its reference capability: you can set the visual style with an image, specify motion and camera work with a video, drive the rhythm with audio, and guide the narrative with text. The result is a level of control that was previously impossible in generative video.

How to Use References

Seedance 2.0 uses an @ mention system to specify how each uploaded asset should be used. This gives you explicit control over what each file contributes to the generation.

Entry Points

• First/Last Frame Mode: Use when you only need a starting image plus a prompt
• Universal Reference Mode: Use for multimodal combinations (images + videos + audio + text)

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

Examples of Reference Instructions

Use Case	Prompt Pattern
Set first frame	@Image1 as the first frame
Reference motion	Reference @Video1 for the fighting choreography
Copy camera work	Follow @Video1's camera movements and transitions
Add music/rhythm	Use @Audio1 for the background music
Extend a video	Extend @Video1 by 5 seconds
Replace character	Replace the woman in @Video1 with @Image1

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: Natural movement with proper momentum and timing
• Precise instruction following: The model understands and executes complex prompts
• Style consistency: Maintains visual coherence 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 the continuous action, fabric physics, and natural body mechanics without explicit guidance.

2. Multimodal Reference System

This is the defining feature of Seedance 2.0. You can reference virtually anything from your uploaded assets:

• Motion patterns from reference videos
• Visual effects and transitions from creative templates
• Character appearances from reference images
• Camera techniques from cinematographic examples
• Audio rhythm and mood from music tracks

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

3. Character and Object Consistency

Previous models struggled with maintaining identity across frames. Seedance 2.0 addresses this directly:

• Face consistency: Characters maintain their appearance throughout
• Product detail preservation: Logos, text, and fine details remain accurate
• Scene coherence: Environments stay consistent across shots
• Style lock: Visual style doesn’t drift during 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. Close-up of him finding his keys, inserting them into
the lock. He enters and his daughter and pet dog run to greet him
with a hug. The interior is warm and cozy, with natural dialogue
throughout.

4. Motion and Camera Replication

Upload a reference video and Seedance 2.0 can extract and apply:

• Complex choreography: Fighting sequences, dance moves, action scenes
• Camera techniques: Dolly shots, tracking, crane movements, handheld feel
• Editing rhythm: Cut timing, transition styles, pacing
• Special movements: Hitchcock zooms, whip pans, orbit shots

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. Exterior scene references @Image3, man
looks around. Reference @Video1's mechanical arm multi-angle
following shots tracking his line of sight.

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
• Editing styles: Music video cuts, documentary pacing, commercial rhythm

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.
Enter the next scene through the angel's pupil, aerial shot of
the angel (spiraling wings match the pupil), camera descends
following the angel's face, pulls back on arm raise to reveal
the stone angel statues in background. One continuous shot
throughout.

6. Video Extension

Extend existing videos while maintaining narrative coherence:

Example prompt:

Extend @Video1 by 15 seconds. Reference @Image1 and @Image2 for
the donkey-on-motorcycle character. Add a wild advertisement
sequence:

Scene 1: Side shot, donkey bursts through fence on motorcycle,
nearby chickens startled.

Scene 2: Donkey performs spinning stunts on sand, tire close-up
then aerial overhead shot of donkey doing circles, dust rising.

Scene 3: Mountain backdrop, donkey launches off slope, ad copy
appears behind through masking effect (text revealed as donkey
passes): "Inspire Creativity, Enrich Life". Final shot: motorcycle
passes, dust cloud rises.

7. Video Editing

Modify existing videos without regenerating from scratch:

• Character replacement: Swap one person for another while keeping the action
• Element addition/removal: Add objects, remove distractions
• Style transfer: Apply new visual treatments
• Narrative changes: Alter the story direction

Example prompt:

Subvert the plot of @Video1. The man's expression shifts instantly
from tender to cold and ruthless. In the moment the woman least
expects it, he shoves her off the bridge into the water. The push
is decisive, premeditated, without hesitation—completely subverting
the romantic character setup. As she falls, no scream, only
disbelief in her eyes. She surfaces and shouts at him: "You were
lying to me from the start!" He stands on the bridge with a cold
smile and says quietly: "This is what your family owes mine."

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
• 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:

Example prompt:

The girl in the poster keeps changing outfits. Clothing styles
reference @Image1 and @Image2. She holds the bag from @Image3.
Video rhythm references @Video1.

For multiple images synced to music:

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.
Adjust reference image framing as needed for music and visual
flow. Add lighting changes between shots.

10. One-Take Continuity

Generate long, unbroken shots with consistent motion:

Example prompt:

@Image1 through @Image5, one continuous tracking shot following
a runner up stairs, through corridors, onto the roof, ending
with an overhead view of the city.

Example prompt:

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

Best Practices

1. Be explicit about references: Write clearly which file is for what purpose. “Reference @Video1’s camera movement” is better than just mentioning the video.

2. Prioritize your uploads: With a 12-file limit, choose assets that have the greatest impact on your output.

3. Check your @ mentions: With multiple files, double-check that you haven’t confused which image, video, or audio goes where.

4. Specify edit vs. reference: Make clear whether you want to edit an existing video or use it as a reference for generating something new.

5. Duration alignment: When extending video, set your generation duration to match the new content length (e.g., extend by 5s = generate 5s).

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