Overview

This node integrates with the KlingAI v2.0 text-to-video generation API to create short videos based on user-provided text prompts. It supports generating videos of 5 or 10 seconds in 720p resolution at 30fps. Users can specify a prompt, a negative prompt to exclude unwanted elements, the video duration, and a CFG scale to control the model's adherence to the prompt. The node sends a request to the API, polls for task completion, and outputs the video URL and status once the generation is finished.

Use Case Examples

1. Generating a 10-second video from a descriptive prompt for marketing content.
2. Creating a 5-second video snippet excluding certain elements using the negative prompt feature.
3. Adjusting the CFG scale to control how strictly the video matches the prompt.

Properties

Output

JSON

• taskid - The unique identifier of the video generation task.
• url - The URL of the generated video once the task is completed.
• status - The status of the video generation task, e.g., 'completed' or 'failed'.

Dependencies

• Wiro API with API key and secret for authentication

Troubleshooting

• If the API response does not include a valid task ID or socket access token, the node throws an error indicating an invalid response from the Wiro API.
• Task status codes '-1', '-2', '-3', and '-4' indicate failure states; users should verify input parameters and API credentials if failures occur.
• Network or authentication issues may cause HTTP request failures; ensure API credentials are correct and network connectivity is stable.
