# ByteDance2TextToVideoNode - ComfyUI Built-in Node Documentation
> This node generates a video from a text prompt using ByteDance's Seedance 2.5 or 2.0 models.
This node generates a video from a text prompt using ByteDance's Seedance 2.5 or 2.0 models. It sends the prompt to the selected model, waits for the video to finish processing, and returns the resulting video file.
## Inputs
### Common Inputs
| Parameter | Description | Data Type | Required | Range |
| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | -------------------------------------------------------------------------------------------- |
| `model` | The Seedance model to use for video generation. Seedance 2.5 is the newest model, supporting videos up to 30 seconds and mp4/mov output; Seedance 2.0 is for maximum quality and 4k; Seedance 2.0 Fast is for speed optimization; Seedance 2.0 Mini is for the fastest, lowest-cost generation. Selecting a model reveals additional inputs for the prompt, resolution, aspect ratio, duration, and audio generation. | DYNAMIC\_COMBO | Yes | `"Seedance 2.5"`
`"Seedance 2.0"`
`"Seedance 2.0 Fast"`
`"Seedance 2.0 Mini"` |
| `seed` | Controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 0) | INT | No | 0 to 2147483647 |
| `watermark` | Whether to add a watermark to the video. (default: False) This is an advanced setting. | BOOLEAN | No | True / False |
### Seedance 2.5 Inputs
| Parameter | Description | Data Type | Required | Range |
| ---------------- | ---------------------------------------------------------------------------------------------------- | --------- | -------- | --------------------------------------------------------------------------------------------- |
| `prompt` | Text prompt for video generation. Put spoken lines in double quotes to steer the generated dialogue. | STRING | Yes | — |
| `resolution` | Resolution of the output video. (default: `"720p"`) | COMBO | Yes | `"480p"`
`"720p"`
`"1080p"` |
| `ratio` | Aspect ratio of the output video. (default: `"16:9"`) | COMBO | Yes | `"16:9"`
`"4:3"`
`"1:1"`
`"3:4"`
`"9:16"`
`"21:9"`
`"adaptive"` |
| `duration` | Duration of the output video in seconds. (default: 5) | INT | Yes | 4 to 30 |
| `generate_audio` | Enable audio generation for the output video. (default: True) | BOOLEAN | Yes | True / False |
| `output_format` | Container format of the output video. (default: `"mp4"`) | COMBO | Yes | `"mp4"` |
### Seedance 2.0 Inputs
| Parameter | Description | Data Type | Required | Range |
| ---------------- | ------------------------------------------------------------- | --------- | -------- | --------------------------------------------------------------------------------------------- |
| `prompt` | Text prompt for video generation. | STRING | Yes | — |
| `resolution` | Resolution of the output video. | COMBO | Yes | `"480p"`
`"720p"`
`"1080p"`
`"4k"` |
| `ratio` | Aspect ratio of the output video. (default: `"16:9"`) | COMBO | Yes | `"16:9"`
`"4:3"`
`"1:1"`
`"3:4"`
`"9:16"`
`"21:9"`
`"adaptive"` |
| `duration` | Duration of the output video in seconds. (default: 7) | INT | Yes | 4 to 15 |
| `generate_audio` | Enable audio generation for the output video. (default: True) | BOOLEAN | Yes | True / False |
### Seedance 2.0 Fast and Seedance 2.0 Mini Inputs
Shared by Seedance 2.0 Fast and Seedance 2.0 Mini; both models expose the same parameters.
| Parameter | Description | Data Type | Required | Range |
| ---------------- | ------------------------------------------------------------- | --------- | -------- | --------------------------------------------------------------------------------------------- |
| `prompt` | Text prompt for video generation. | STRING | Yes | — |
| `resolution` | Resolution of the output video. | COMBO | Yes | `"480p"`
`"720p"` |
| `ratio` | Aspect ratio of the output video. (default: `"16:9"`) | COMBO | Yes | `"16:9"`
`"4:3"`
`"1:1"`
`"3:4"`
`"9:16"`
`"21:9"`
`"adaptive"` |
| `duration` | Duration of the output video in seconds. (default: 7) | INT | Yes | 4 to 15 |
| `generate_audio` | Enable audio generation for the output video. (default: True) | BOOLEAN | Yes | True / False |
**Note:** The `model` selector is dynamic; the inputs shown under each model section appear when that model is selected. The prompt must be at least 1 character long after removing whitespace. Resolution and duration limits depend on the selected model: Seedance 2.5 supports 480p/720p/1080p and 4 to 30 seconds, Seedance 2.0 supports 480p/720p/1080p/4k and 4 to 15 seconds, and Seedance 2.0 Fast and Seedance 2.0 Mini support only 480p/720p and 4 to 15 seconds. The `seed` value only controls whether the node re-runs; it does not make results deterministic.
## Outputs
| Output Name | Description | Data Type |
| ----------- | ------------------------- | --------- |
| `video` | The generated video file. | VIDEO |
