ComfyUI Node: Video Extend

Video Extend:

The Video Extend node is designed to enhance and extend existing video content by leveraging the capabilities of the KLingAI API. This node allows you to input a video identifier and a descriptive prompt to generate an extended version of the video, potentially adding new scenes or elements based on the provided prompt. The primary benefit of using this node is its ability to creatively augment video content, making it a powerful tool for AI artists looking to explore new dimensions in their video projects. By utilizing the KLingAI API, the node ensures that the video extension process is both efficient and effective, providing users with a seamless experience in enhancing their video content.

Video Extend Input Parameters:

client

The client parameter is a reference to the KLingAI API client, which is essential for authenticating and making requests to the API. This parameter ensures that the node can communicate with the KLingAI service to perform the video extension task. It does not have specific minimum or maximum values as it is a client object.

video_id

The video_id parameter is a string that uniquely identifies the video you wish to extend. It is crucial for specifying which video the node should process. The parameter is expected to be a single-line string, and while there is no explicit minimum or maximum length, it should match the format required by the KLingAI API.

prompt

The prompt parameter is a multiline string that provides a descriptive narrative or instructions for how the video should be extended. This input significantly impacts the final output, as it guides the AI in generating new content that aligns with the user's creative vision. The prompt can be as detailed as necessary to convey the desired outcome, and there is no strict limit on its length, allowing for comprehensive descriptions.

Video Extend Output Parameters:

url

The url output parameter is a string that provides the web address where the extended video can be accessed. This URL is crucial for retrieving and viewing the newly generated video content, allowing you to easily share or download the video for further use.

video_id

The video_id output parameter is a string that represents the identifier of the newly extended video. This ID is important for tracking and referencing the specific video generated by the node, especially if you plan to perform additional operations or extensions on the same video in the future.

Video Extend Usage Tips:

• Ensure that your prompt is detailed and specific to achieve the best results, as the quality and relevance of the extended video heavily depend on the clarity of the instructions provided.
• Verify that the video_id corresponds to the correct video you intend to extend, as any errors in this parameter could lead to processing the wrong video.

Video Extend Common Errors and Solutions:

Invalid video_id

• Explanation: The video_id provided does not match any existing video in the KLingAI database.
• Solution: Double-check the video_id for any typos or errors and ensure it corresponds to a valid video in the KLingAI system.

API client authentication failed

• Explanation: The client parameter is not properly authenticated, preventing access to the KLingAI API.
• Solution: Ensure that the API client is correctly configured with valid authentication credentials and has the necessary permissions to access the video extension service.

Empty prompt

• Explanation: The prompt parameter is empty or lacks sufficient detail, leading to unsatisfactory video extension results.
• Solution: Provide a comprehensive and detailed prompt to guide the AI in generating the desired video content.
