Seedance 2 Fast AI Video Generator
Choose Seedance 2 Fast when the current Fast-labelled setup and its 15-second default fit a multimodal video direction with 480p or 720p delivery.
Seedance 2 Fast task directions
These local video examples are attributed to the Seedance family. They show task directions, not a benchmark between model versions.
Every card identifies whether it is a verified model-family example or a visual reference. Reference cards are not model benchmarks or before-and-after claims.

How to create a video with Seedance 2 Fast
Start with the planned clip duration, then give the prompt and any compatible media one consistent role in the movement direction.
- 1
Plan the clip as one timed beat
Choose the intended duration before writing the action, then make the camera and source media support that same beat.
- 2
Add reference media when needed
Add approved compatible media only when an existing frame, motion, or sound should guide the result.
- 3
Confirm duration and output controls
Confirm the current 4–15 seconds, 480P / 720P, and 6 aspect-ratio choices in the workspace before generation.
- 4
Generate and review continuity
Before public use, inspect subject motion, camera changes, visible text, sound, and the final frame.
Checks before you create and publish
- Treat the workspace as current
- Model availability and settings can change. Use the options shown in the current workspace before you submit.
- Use approved source media
- When you upload images, video, or audio, confirm that you are allowed to use and publish it for the current project.
- Review the generated video
- Before publishing, manually check motion continuity, text, sound, people, product details, and marks.
