AI video generation has taken a major leap forward with Seedance 2.0. Built by Jimeng AI, this model now accepts four input modalities — image, video, audio, and text — giving creators unprecedented control over their outputs. You can set the visual style with a reference image, define motion and camera work with a reference video, drive rhythm with an audio clip, and fine-tune everything with natural language prompts. It transforms video generation from a one-shot process into something closer to actual directing.
This guide covers Seedance 2.0’s full parameter specs, core capability upgrades, how to write effective multimodal prompts, and every key feature in detail.
What Is Seedance 2.0?
Seedance 2.0 is the latest AI video generation model from Jimeng AI. It supports four input modalities — images, videos, audio files, and text — which can be freely combined to produce controllable video outputs of up to 15 seconds. Every generated video comes with built-in sound effects and background music.
The standout upgrade is its reference capability:
- Reference images precisely reproduce composition and character details.
- Reference videos replicate camera movements, complex action rhythms, and creative effects.
- Videos support smooth extension and seamless stitching, enabling continuous “keep shooting” workflows.
- Editing capabilities allow character swaps, additions, deletions, and segment adjustments on existing videos.
Video creation is not just about generation — it is about control. Seedance 2.0 delivers both.

Core Capability Upgrades
Seedance 2.0 is not just about multimodal input — the foundational generation quality has improved significantly.
More realistic physics. Objects and environments behave according to natural laws, making scenes look more believable.
Smoother motion. Complex actions and continuous movement sequences render more naturally and fluidly.
More precise prompt understanding. The model follows instructions more accurately, reducing the gap between what you describe and what you get.
More stable style consistency. Visual style stays coherent across frames, reducing the flickering and drift common in earlier models.
Even for straightforward text-to-video tasks, Seedance 2.0 produces noticeably more realistic and reliable results.
Multimodal Reference: The Headline Feature
The multimodal reference system is the defining capability of Seedance 2.0. Any uploaded asset — image, video, or audio — can serve as either a subject or a reference. You can reference actions, special effects, visual style, camera movements, characters, scenes, and sounds. As long as your prompt clearly describes what to reference and how, the model interprets it.
The formula: Multimodal Reference (reference anything) + Strong Creative Generation + Precise Instruction Following.
How to Write Effective Prompts
Use natural language and the @ notation to specify which file serves which purpose. Be clear about whether each asset is a reference or an editing target. Here are practical patterns:
First/last frame + video reference: “Use @Image1 as the first frame, and reference the fighting choreography from @Video1.”
Video extension: “Extend @Video1 by 5 seconds.” Set the generation duration to match the desired extension (e.g., select 5s to add 5s).
Video fusion: “Insert a new scene between @Video1 and @Video2, with the content showing [describe scene].”
Audio from video: No separate audio file? You can reference the sound directly from an uploaded video.
Continuous action: “The character transitions from a jump directly into a roll, maintaining fluid and coherent motion. @Image1 @Image2 @Image3…”
When uploading multiple files, double-check that each @ reference is clearly labeled. Do not mix up images, videos, and characters.
What Seedance 2.0 Can Do
Beyond the multimodal reference system, Seedance 2.0 resolves many long-standing pain points in AI video generation and introduces several practical creative capabilities.
Consistency Across Characters, Objects, and Scenes
Characters changing appearance mid-video, product details disappearing, text becoming blurry, scenes shifting unexpectedly — these consistency issues have plagued AI video generation. Seedance 2.0 significantly improves consistency from facial features and clothing to font details, delivering stable results across the entire clip.
Input
A man, worn out after work, walks down the corridor. His pace slows, and he finally stops at the door of his home.
Close-up on his face: the man takes a deep breath, adjusts his emotions, puts away his negative feelings, and relaxes.
Close-up of him rummaging for his keys, inserting one into the lock.
After he enters the house, his young daughter and a pet dog happily run over to greet him with a hug.
The interior is very warm and cozy, with natural dialogue throughout.
Output
Precise Camera Movement and Action Replication
Replicating specific cinematic techniques used to require extremely detailed prompts — or was simply impossible. Now you just upload a reference video. The model replicates the camera language, movement patterns, and action rhythms directly, no complex prompt engineering needed.
Creative Template and Effects Replication
Seedance 2.0 can reproduce creative transitions, advertisement sequences, cinematic segments, and intricate editing patterns from a reference. The model identifies action rhythm, camera language, and visual structure, then generates a precise recreation. You do not need professional terminology — simply write something like “Reference the rhythm and camera work from @Video1, and the character design from @Image1,” and the model handles the rest.
Creative Intelligence and Story Completion
Seedance 2.0 does more than follow instructions. It can fill in narrative gaps and generate contextually appropriate story continuations, making it useful when you need the model to contribute creatively — not just execute commands.
Video Extension and Continuity
You can extend an existing video by specifying the additional duration, and the model generates continuous footage that maintains visual and narrative coherence. Videos also support smooth transitions and seamless stitching between clips. This enables a “keep shooting” workflow: build sequences shot by shot, with each new segment connecting naturally to the previous one.
Audio Accuracy and Sound Realism
Seedance 2.0 delivers more accurate timbres and more realistic sound design. Generated sound effects and background music are better matched to the visual content, creating a cohesive audiovisual result without requiring separate audio post-production.
Long-Take Camera Coherence
The model maintains smooth, unbroken camera movement across the full duration of a generated video. Long-take or “one-shot” sequences feel like continuous single-take footage rather than stitched-together segments — a significant improvement for cinematic-style content.
Video Editing on Existing Footage
Sometimes you already have a video and just need to adjust part of it — tweak an action, extend a few seconds, or make a character’s performance better match your vision. Seedance 2.0 supports targeted editing: use a video as input and make directed modifications to specific clips, actions, or rhythms without altering the rest. Character swaps, additions, deletions, and segment adjustments are all supported. No need to regenerate from scratch.
Beat-Synced Music and Emotional Expression
Visual actions and transitions can align with the rhythm of uploaded audio, making Seedance 2.0 ideal for music videos, promotional content, and any project where visual-audio synchronization matters. Character animation also features more nuanced facial expressions and body language — emotional performances are more naturalistic, well-suited for narrative and character-driven content.
Conclusion
Seedance 2.0 represents a genuine shift in AI video generation. By accepting images, videos, audio, and text as combined inputs, it gives creators real control over visual style, camera movement, rhythm, and emotional tone. The improvements in consistency, physics, editing, and audio make it a practical tool for professional workflows. Whether you are producing short-form content, advertisements, or cinematic sequences, Seedance 2.0 brings AI video closer to a true directing experience.
