Seedance 2 model details
How to use Seedance 2 for smooth action, realistic human video, multi-shot consistency, synchronized audio, and creator-ready vertical video.
Seedance 2 is a strong fit for motion-heavy short video: realistic people, dance, fashion, fighting scenes, product movement, social ads, and simple story beats. It combines first/last-frame guidance, duration and resolution choices, sound support, web search, and practical creator controls.
What is Seedance 2 best for?
Seedance 2 is useful for people in motion, dance and fashion clips, action scenes, product movement, narrative social ads, and short creator videos. It is a good choice when the main quality bar is fluid, readable movement with stable timing.
- People and action
- Dance or fashion clips
- Fighting scenes
- Short narrative videos
How do first and last frame images help?
First and last frame guidance lets you shape where the clip begins and ends. Use it when the movement arc matters, such as a pose change, product reveal, scene transition, or before-and-after effect.
- First/last-frame control
- Up to 2 images
- Better movement arcs
- Useful for reveals
Which Seedance 2 settings should I use?
Use 5 seconds for fast tests and 10 seconds for more complete motion. Choose 720p for iteration, 1080p for sharper candidates, and vertical aspect ratios for Reels, Shorts, and TikTok-style posts.
- 5s and 10s
- 720p and 1080p
- Vertical social formats
- Optional generated audio
Seedance 2 vs Seedance 1.5: what changed?
Seedance 2 is better for richer movement, realistic human scenes, multi-shot consistency, stronger creator controls, and more polished output. Seedance 1.5 remains useful for fast, lower-cost social video tests and simpler motion ideas.
- 2 for stronger motion
- 1.5 for low-cost tests
- 2 for human scenes
- 1.5 for simple drafts
How do I prompt Seedance 2 for smoother action?
Describe the performer or subject, the exact movement, the camera relationship, pace, lighting, and whether the shot should feel like an ad, music-video moment, fashion clip, or documentary scene.
- Describe movement clearly
- Set camera relationship
- Guide pace
- Name the content format
