ダンスやアクションシーンに最適なのは？Seedance vs 他モデル
When it shines
Seedance is the clear winner for any content involving human body movement — dance videos, fitness demos, martial arts, sports highlights, fashion runway walks, and action sequences. No other AI video model renders complex choreography, body mechanics, and physical motion with this level of fidelity. At 20 credits per video, it's also surprisingly affordable for the quality you get. Choose Seedance whenever the human body is the star of the shot.
When to pick a different model
If your video doesn't feature human movement — product shots, landscapes, architecture, abstract visuals — other models will serve you better. Veo 3.1 for cinematic quality, Kling for speed, Runway for cost efficiency. The 5-second duration limit also means Seedance isn't ideal for narrative content that needs longer scenes. And if you need audio with your video, Veo 3.1 is the only model with auto sound effects.
Limitations worth knowing
- 5-second maximum duration. Seedance clips are limited to 5 seconds — the shortest among video models. For dance routines or action sequences that need more time, you'll need to generate multiple clips and combine them.
- No audio output. Despite being named 'Seedance', the model doesn't generate music or sound. You'll need to pair the video with your own audio track. Only Veo 3.1 auto-generates sound effects among our models.
- Weaker on non-human subjects. Seedance is optimized for human motion. For landscape, product, or architectural content, Veo or Kling produce better results. Seedance's strength is specifically body movement.

AIに振り付けをする — Seedanceのプロンプト戦略
1
Describe the Movement
Seedance shines with motion descriptions. Be specific about what the body is doing — 'hip-hop popping', 'ballet pirouette', 'yoga flow'. The more specific the movement, the better.

Set the Scene
Combine movement with environment for context. A dancer on stage feels different from a dancer in the rain. The environment amplifies the emotional impact.
3
Mention Music Mood
Even though Seedance doesn't generate audio, mentioning the music mood helps guide the visual style — 'to upbeat EDM' vs 'to melancholic piano'.
