💡How to Use the @Mention System for Professional AI Video?

Seedance 2.0 Omniは、統一された「クアッドモーダル」入力システムを提供する最初のモデルです。テキスト、画像、動画、音声を同時に処理し、精度の高いシネマティック・コンテンツを作成します。.

The core of this system is the @Mention logic. Seedance 2.0 currently supports uploading three types of files as references: image, video, and audio. By tagging your uploaded files (e.g., @img1, @vid1), you can tell the AI exactly which file to use for character appearance, movement, or sound.

Seedance-style @Mention prompting usually follows this logic:

Use @Image1 for identity.
Use @Video1 for motion and camera movement.
Use @Audio1 for rhythm, voice, or atmosphere.

This makes your prompt more controllable because every reference has a clear job. You can also freely combine the materials as references. The common usage methods can be found in the cheat sheet I have prepared below.

Seedance @Mention Cheat Sheet

We have provided a vast number of examples and replicable prompts. クリック to view more. The following text also provides other usage examples for your reference.

What @Image Does

What @Video Does

用途 ビデオ when you want to copy motion, rhythm, camera movement, or a viral video structure.

What @Audio Does

用途 オーディオ when rhythm, voice, sound design, or pacing matters.

However, the references you have uploaded must meet the following conditions:

💡Step-by-Step Guide: Mastering Omni Mode with 12 Multi-Modal Assets

Start by preparing your assets. Please make sure that the file you upload complies with the requirements. If it doesn’t, the upload will fail. You can make the necessary modifications according to the prompts on the page.

ダッシュボードにファイルをアップロードし、@タグを付けます。プロンプトでは、“キャラクターの顔は@img1を参照”、“カメラのパスは@vid1に従ってください ”と具体的に書いてください。”

例

@Reference the man's image in @image 1, in the elevator in @image 2, fully referencing all camera movements and the main character's facial expressions from @video 1. The main character uses Hitchcock zoom when in fear, then several surrounding shots show the perspective inside the elevator. The elevator door opens, and a tracking shot follows the man exiting the elevator. The scene outside the elevator references @image 3, where the man looks around, with multiple angles following his line of sight using a robotic arm as in @video 1.

💴Seedance Prompt Examples by Use Case

The multimodal reference function has different functions in different scenarios. Seedance 2.0 is strongest when you choose a clear use case before writing the prompt. A creator video, logo animation, product ad, and cinematic short film should not use the same prompt structure.

💡Edit Videos

を使用することができます。 Video Edit feature of シーダンス2.0 when you need to transform or refine existing footage without re-shooting. This powerful “Multimodal-Reference” capability is ideal for the following scenarios:

• Scene & Background Swapping: Change the environment of your original video (e.g., moving a product from a studio to a beach) by using イメージ as a new environment reference while preserving the original subject’s motion.
• Visual Style Transfer: Apply the “Visual DNA” (lighting, color palette, and mood) of a viral ad or a cinematic masterpiece to your own raw footage using ビデオ as a style reference.
• Character & Outfit Consistency: Update or maintain the appearance of a character across different shots by referencing a specific character sheet or outfit photo via イメージ.
• Dynamic Product Placement: Insert a product into a lifestyle scene while ensuring it inherits the realistic lighting and reflections of the surrounding environment.
• Rhythmic Re-timing: Sync your existing video’s motion to a new soundtrack using オーディオ, allowing the AI to adjust the pacing and transitions to match new musical beats.

Essentially, Seedance 2.0 Video Edit acts as an AI-powered Director of Photography, allowing you to keep the “action” of your video while completely overhauling the “aesthetic” and “context.”

ステップ・バイ・ステップ・ガイド

• Step1: Provide the video to be edited, reference images or audio.
• Step2: Use prompts together to complete various video editing tasks, such as replacing the video subject, adding, deleting and modifying objects in the video, redrawing/repairing partial frames, etc.

例

Keep the camera movement, pacing, and action rhythm from @Video1.
Replace the original subject with the person/product from @Image1.
Preserve the motion blueprint, but change the visual identity…

💡Extend Videos

について ビデオの延長 feature in Seedance 2.0 is your primary tool for overcoming technical duration limits and building long-form narrative content. Here is when you should utilize this functionality:

• Surpassing the 15s Limit: Since a single Seedance generation is capped at a maximum of 15 seconds, you can use the Extend feature to continue the action seamlessly, allowing you to build 30-second ads, 1-minute explainers, or even full-length cinematic scenes.
• Sequential Storytelling: If you have successfully generated a “Hero Shot” of your product, you can extend that video to transition into a new scene—such as moving from a close-up texture shot to a wide-angle lifestyle shot—without losing visual consistency.
• Refining Pacing and Flow: Use the extension tool to add “breathing room” to a clip. If an action finishes too abruptly, extending the video allows the AI to generate a natural follow-through or a lingering cinematic ending.
• Developing Character Arcs: For creators and filmmakers, the Extend feature is essential for maintaining character and environment stability over a longer duration, ensuring that the “Visual DNA” established in the first few seconds remains intact as the story progresses.
• Dynamic Loop Creation: You can extend existing footage to create perfect, high-quality loops for social media backgrounds or digital billboards, ensuring the motion remains fluid and the lighting stays consistent.

By treating each 15-second generation as a “building block,” the ビデオの延長 feature effectively transforms Seedance 2.0 from a clip generator into a comprehensive video production suite.

Based on the original video, you can extend the video forward or backward, or stitch multiple video clips (up to 3 clips) into a coherent video.

例

Extend the video, tracking shot of a man in orange riding a brown horse, he speeds up and runs to a large tree with orange flowers, breaks off two flowers from the branch, then other people successively ride into the frame. The camera zooms in to capture the man in orange dismounting, the camera quickly circles him, he turns and walks towards a woman in white riding a white horse, presenting the flowers to her. Chinese style portrait style, 3D, cheerful folk music.

🙅‍Seedance Limits and How to Work Around Them

Even with strong prompts, Seedance has limits. The best way to improve output quality is to understand what the model handles well and where you need to give stricter instructions.

File Input Limits: How Many References Can You Use?

Your current Seedance cluster explains a reference setup built around:

The key is not to upload as many files as possible. The key is to assign every file a clear role.

例1：

@Image1 A girl breaks the fourth wall, continuously traveling through multiple famous painting worlds, retaining real textures while the oil painting worlds present a 3D high-saturation animation style. She stands excitedly under the swirling starry sky of @Image2; then curiously watches the embracing couple of @Image3 who shyly cover their heads with a blanket; subsequently takes a selfie with the Girl with a Pearl Earring in @Image4; immediately enters @Image5 passing between two samurai; makes funny faces and screams with the figure in @Image6; runs to the Mona Lisa in @Image7, getting patted on the head..."

例2：

Reference @Image1 storyboard script, reference the shots, framing, camera movement, visuals, and copy of @Image1, the character is @Image2, the scene is @Image3, the prop is @Image4, create a 15s healing video.

Duration: How Long Can Seedance Generate?

Seedance workflows commonly work best in short controlled clips. The existing cluster content describes a 4–15 second generation range in more advanced web/API-style workflows, while some app-based workflows use fixed shorter presets.

For prompt quality, the practical recommendation is:

You can upload the ending part of an existing video and ask Seedance 2.0 to extend it.

Extend @video1 for 5 minutes,[detailed request]

Resolution: Does Seedance Support 1080p?

Yes. Seedance supports 1080p-style HD output, and some workflows also discuss higher-resolution or 2K-oriented rendering depending on the platform and settings. For most creators, 1080p is the practical sweet spot for YouTube, TikTok, Reels, Shorts, client previews, and paid social ads.

Recommended resolution settings:

Common reason your video looks soft:

• source image is low quality
• default export is set to 720p
• prompt lacks sharp detail instructions
• lighting is too dark or noisy
• too many moving elements
• the subject is too small in frame

FAQ: Seedance Prompt Guide

How do I write a good Seedance prompt?

Use a director-style structure: subject, action, scene, camera, style, reference, and constraints. Be specific about what should happen and what must stay consistent.

What is @Mention in Seedance?

@Mention lets you reference uploaded files directly in your prompt. For example, 画像1 can define a character, product, logo, or style, while ビデオ1 can define motion or camera movement.

How do I use @Image in Seedance?

Upload an image and tell Seedance exactly how to use it. For example: “Use @Image1 as the main character reference” or “Use @Image1 as the exact product design.”

How do I use @Video in Seedance?

Use @Video when you want to transfer motion, camera movement, or pacing from an existing clip. For example: “Use @Video1 as the camera and motion reference, but replace the subject with @Image1.”

Can Seedance recreate viral videos?

Seedance can use a reference video as a motion blueprint, then replace the original subject with your own character or product reference. You should avoid copying protected branding, faces, or copyrighted material directly.

Can Seedance animate logos?

Yes. Use a clean logo image, preferably a high-resolution transparent PNG, and write clear instructions to keep the logo shape, typography, color, and spacing unchanged.

Does Seedance support 1080p?

Yes, Seedance workflows can support 1080p-style HD output, and some workflows reference higher-quality 2K generation. For most creators, 1080p is ideal for social media, YouTube, ads, and client previews.

How long can Seedance videos be?

Many Seedance workflows are built around short controlled clips, commonly 4–15 seconds depending on the platform and settings. For longer videos, generate multiple clips and edit them together.

Why does my Seedance video look blurry?

Common reasons include low-resolution source images, default 720p settings, weak lighting instructions, too much motion, or vague prompts. Use clear reference images and add “sharp focus, clean lighting, high detail.”

Why does Seedance change my character or logo?

The model may not understand which details are fixed unless you say so clearly. Use strict language such as “keep the face unchanged” or “keep the logo typography, shape, color, and spacing unchanged.”

Can Seedance generate perfect text inside videos?

Not reliably. For exact text, slogans, captions, UI labels, or product copy, add the text later during editing.

What is the best Seedance prompt length?

A good prompt is usually detailed but not overloaded. For one clip, 80–180 words is often enough. For multi-shot videos, use a structured shot list instead of one long paragraph.

Conclusion: Seedance Prompting Is About Control

The best Seedance results do not come from writing longer prompts. They come from giving the model clearer control instructions.

用途 イメージ to lock identity, product shape, logo design, or visual style. Use ビデオ to control motion and camera movement. Use オーディオ to guide rhythm, voice, pacing, or sound. Then write the prompt like a director: one subject, one main action, one clear scene, one camera plan, and strict consistency rules.

If your output fails, do not start over blindly. Fix the weak part: identity, motion, camera, resolution, duration, or reference role.

With the right prompt structure, Seedance 2.0 can become a practical production tool for creators, advertisers, brand teams, and AI filmmakers who need controlled, cinematic video generation instead of random AI clips.
