Seedance 2.0 @Tags: How to Direct AI Videos with Multimodal References

Most AI video generators take a text prompt and give you whatever they feel like. Seedance 2.0 works differently — you upload images, videos, and audio files, then use @tags to tell the model exactly what each file should do.

Think of it like a film director's shot list. Each uploaded file gets a role:

  • @Image1 as the first frame — pins the opening visual
  • @Video1 for camera movement reference — copies the cinematography
  • @Audio1 as background music — sets the soundtrack and rhythm

You can combine up to 12 files (9 images + 3 videos + 3 audio) in a single generation.

The @Tag Syntax

The format is simple: @ + asset type + number.

Tag Type Range Example
@Image 1-9 @Image1, @Image2
@Video 1-3 @Video1
@Audio 1-3 @Audio1

Quick API Example

import requests

response = requests.post(
    "https://api.evolink.ai/v1/videos/generations",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={
        "model": "seedance-2-0-t2v",
        "prompt": "A cinematic sunset over the ocean, @Image1 as first frame, @Audio1 as background music. Slow dolly forward with warm golden light.",
        "image_urls": ["https://example.com/sunset.jpg"],
        "audio_urls": ["https://example.com/ambient.mp3"],
        "duration": 10,
        "quality": "1080p"
    }

What Makes @Tags Different

No other AI video API offers this level of multimodal control:

  • Sora 2: Text + single image input only, no audio reference
  • Kling 3.0: Image-to-video but no @tag assignment system
  • Veo 3.1: Text-only prompts, generates its own audio

Seedance 2.0's @tag system lets you direct the generation rather than just describe it.
