Case 2 · Creative Narrative — Cola Advertisement
Input: 1 reference image + text
The character in the painting has a guilty expression, eyes glancing left and right as they peek out of the frame, quickly reaching out to grab a cola and take a sip, then showing a satisfied expression. Suddenly footsteps are heard, the character quickly puts the cola back in place. A western cowboy picks up the cup with cola and walks away. Finally, the camera pushes forward and the scene slowly becomes a pure black background with only top lighting illuminating the canned cola. At the bottom of the frame, artistic subtitles and voiceover appear: "Yikou Cola, a must-try!"

🎮 Interaction Method
Use @material_name in the prompt to specify the role of each material. Upload order is the numbering order:
@image1 as the first frame, @video1 as reference for camera language, @audio1 for background music
| Entry Point | Use Case |
|---|---|
| First/Last Frame | Upload only first frame (or first + last frame) + prompt |
| All-in-One Reference | Multimodal combination input (image + video + audio + text) |
Common Writing Patterns:
# Specify first frame
Use @image1 as the first frame of the scene, ...
# Reference camera movement only, not character
Reference all camera movement effects from @video1, but use the character appearance from @image1
# Separate action and camera movement references
Reference character action from @video1, reference circular camera movement from @video2
# Video extension (generated duration = new seconds, not total duration)
Extend @video1 by 5s, [content description]
# Reference video sound effects
Background BGM references sound effects from @video1
💡 Advanced Techniques
Prompt Writing
- Long videos (10s+) use timeline segmentation:
0-3s: [description] / 3-6s: [description] - Actions/emotions must be specific: ❌
character is very sad→ ✅tears slide down cheeks, mouth trembles slightly - One-shot must end with:
No scene cuts throughout, one continuous shot.
Keyword-Triggered Effects
| Desired Effect | Recommended Writing |
|---|---|
| Hitchcock zoom | protagonist in panic with Hitchcock zoom |
| Circular camera | robotic arm multi-angle circular movement |
| Accelerating speed | speed accelerates like a roller coaster |
| Particle effects | golden sand particles scatter / particle dispersion effect |
Multimodal Combination Strategy
| Dimension You Want to Control | Material to Use |
|---|---|
| Character appearance | Image (multiple angles) |
| Camera movement | Video (reference camera language) |
| Action | Video (reference action) |
| Voice/tone | Video (reference video with dialogue) |
| Background music rhythm | Video or audio |
| Scene style | Image (scene reference) |
Common Issues
- Reference video didn't replicate camera movement? → Add
completely reference all camera movement effects from @video1 - Character appearance inconsistent? → Upload multi-angle images, add to prompt
maintain character appearance exactly consistent with @image1 - Video extension seams unnatural? → Start extension prompt describing the state of the last frame of original video
