Seedance 1.5 model details
A lightweight guide to Seedance 1.5 for fast motion tests, short social videos, image-guided clips, and affordable creator workflows.
Seedance 1.5 is a useful previous-generation option when you want simple motion, lower credit cost, and fast social video drafts. It is best used for testing people, products, and creator scenes before investing in Seedance 2 or another higher-control model.
What can I create with Seedance 1.5?
Seedance 1.5 is useful for quick social video ideas, motion tests, simple character movement, image-to-video drafts, and low-cost prompt exploration. It is a practical model when you need many drafts before choosing a final direction.
- Short social clips
- Motion tests
- Affordable drafts
- Simple image-to-video
Which duration should I choose?
Use 4 seconds for fast tests, 8 seconds when the motion needs a little more time, and 12 seconds for fuller short clips. Higher duration gives the scene more room but should use a clearer prompt.
- 4s for fast tests
- 8s for medium motion
- 12s for fuller clips
- 480p/720p options
When should I upload images?
Use image input when the subject, person, product, or composition should stay recognizable. Text-only prompts are better for broad exploration where no exact starting visual is required.
- Up to 2 input images
- Better subject control
- Useful for social scenes
- Keep prompts simple
When should I upgrade to Seedance 2?
Upgrade to Seedance 2 when the clip needs stronger motion, higher resolution, first/last frame control, or more polished creator output. Stay with 1.5 for quick, economical tests.
- 1.5 for speed
- 2 for polish
- 1.5 for budget
- 2 for better controls
How should I handle failed or weak results?
If a run fails, GemiOmni returns credits through the normal failed-task flow. If a result is weak, simplify the action, reduce conflicting style requests, or move the same idea to Seedance 2.
- Automatic failed-job refunds
- Simplify action
- Reduce conflicts
- Try Seedance 2 for harder shots
