Edit on GitHubThe Vidu2 Reference-to-Video Generation node creates a video from a text prompt and multiple reference images. You can define up to seven subjects, each with its own set of reference images, and reference them in the prompt using
@subject{subject_id}. The node generates a video with configurable duration, aspect ratio, and movement.
Inputs
| Parameter | Data Type | Required | Range | Description |
|---|---|---|---|---|
model | COMBO | Yes | "viduq2" | The AI model to use for video generation. |
subjects | AUTOGROW | Yes | N/A | For each subject, provide up to 3 reference images (7 images total across all subjects). Reference them in prompts via @subject{subject_id}. |
prompt | STRING | Yes | N/A | The text description used to guide the video generation. When the audio parameter is enabled, the video will include generated speech and background music based on this prompt. |
audio | BOOLEAN | No | N/A | When enabled, the video will contain generated speech and background music based on the prompt (default: False). |
duration | INT | No | 1 to 10 | The length of the generated video in seconds (default: 5). |
seed | INT | No | 0 to 2147483647 | A number used to control the randomness of the generation for reproducible results (default: 1). |
aspect_ratio | COMBO | No | "16:9""9:16""4:3""3:4""1:1" | The shape of the video frame. |
resolution | COMBO | No | "720p""1080p" | The pixel resolution of the output video. |
movement_amplitude | COMBO | No | "auto""small""medium""large" | Controls the movement amplitude of objects in the frame. |
- The
promptmust be between 1 and 2000 characters long. - You can define multiple subjects, but the total number of reference images across all subjects must not exceed 7.
- Each individual subject can have a maximum of 3 reference images.
- Each reference image must have a width-to-height ratio between 1:4 and 4:1.
- Each reference image must be at least 128 pixels in both width and height.
Outputs
| Output Name | Data Type | Description |
