Try Seedance 2.0 - Text to Video in the Workbench
Run this model interactively, tune parameters, and compare outputs.
bytedance-seedance-2-0-text-to-video
ByteDance Seedance 2 text-to-video generates video from a text prompt. It supports 480p or 720p output, durations from 4–15 seconds or automatic length from the prompt, multiple aspect ratios (including auto), and optional synchronized audio (effects, ambience, and lip-synced speech).
Example request
- Sync
- Async
- Async with SSE
This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.

Request parameters
Required parameters
| Field | Type | Default | Description |
|---|---|---|---|
prompt | string | "An octopus finds a football in the ocean and excitedly calls its octopus friends to come and play. Cut scene to an octopus football game under the sea." | The text prompt used to generate the video. |
Optional parameters
| Field | Type | Default | Description |
|---|---|---|---|
resolution | string | "720p" | Video resolution - 480p for faster generation, 720p for balance. One of: 480p, 720p. |
duration | string | "auto" | Duration of the video in seconds. Supports 4 to 15 seconds, or auto to let the model decide based on the prompt. One of: auto, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15. |
aspect_ratio | string | "auto" | The aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide. One of: auto, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16. |
generate_audio | boolean | true | Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not. |
seed | integer | — | Random seed for reproducibility. Note that results may still vary slightly even with the same seed. |
