ComfyUI Node: Extend Generation

Extend Generation:

The LumaExtendGeneration node is designed to create a video by extending from an initial image or generation to a final image or generation. This node leverages the capabilities of the LumaAI API to generate smooth transitions between the provided keyframes, resulting in a coherent and visually appealing video. The primary benefit of this node is its ability to seamlessly blend different visual elements, making it ideal for creating dynamic video content from static images or previously generated frames. By specifying either images or generation IDs for the start and end points, you can control the visual narrative and ensure the generated video aligns with your creative vision.

Extend Generation Input Parameters:

client

This parameter represents the LumaAI client instance used to interact with the LumaAI API. It is essential for authenticating and making requests to the API.

prompt

The prompt is a textual description that guides the generation process. It helps the AI understand the context and style of the video you want to create. The prompt should be clear and descriptive to achieve the desired results.

save

A boolean parameter that determines whether the generated video should be saved locally. If set to True, the video will be downloaded and saved to the specified directory. If False, the video will only be available via a URL.

init_image_url

The URL of the initial image to start the video generation. This parameter is optional and should not be used simultaneously with init_generation_id. If provided, the video will begin with this image.

final_image_url

The URL of the final image to end the video generation. This parameter is optional and should not be used simultaneously with final_generation_id. If provided, the video will conclude with this image.

init_generation_id

The ID of the initial generation to start the video. This parameter is optional and should not be used simultaneously with init_image_url. If provided, the video will begin with this generation.

final_generation_id

The ID of the final generation to end the video. This parameter is optional and should not be used simultaneously with final_image_url. If provided, the video will conclude with this generation.

filename

An optional parameter to specify the filename for the saved video. If not provided, the video will be saved with the generation ID as the filename.

Extend Generation Output Parameters:

ui

This output parameter contains a dictionary with a text key, which holds the new generation ID. This ID can be used for further processing or reference.

result

The result parameter is a tuple containing the URL of the generated video and the new generation ID. The video URL can be used to view or download the video, while the generation ID can be used for future reference or additional operations.

Extend Generation Usage Tips:

• Ensure that you do not provide both an image URL and a generation ID for the same keyframe (initial or final) to avoid conflicts.
• Use clear and descriptive prompts to guide the AI in generating the desired video content.
• If you want to save the generated video, set the save parameter to True and specify a filename if needed.

Extend Generation Common Errors and Solutions:

You must provide at least one generation id

• Explanation: This error occurs when neither an initial nor a final generation ID is provided.
• Solution: Ensure that you provide at least one generation ID (either initial or final) to proceed with the video generation.

You cannot provide both an init image and a init generation

• Explanation: This error occurs when both an initial image URL and an initial generation ID are provided simultaneously.
• Solution: Provide only one of the two options for the initial keyframe: either an image URL or a generation ID.

You cannot provide both a final image and a final generation

• Explanation: This error occurs when both a final image URL and a final generation ID are provided simultaneously.
• Solution: Provide only one of the two options for the final keyframe: either an image URL or a generation ID.

Generation failed: <failure_reason>

• Explanation: This error indicates that the video generation process failed due to a specific reason provided by the API.
• Solution: Review the failure reason provided in the error message, adjust your input parameters accordingly, and try again. If the issue persists, consult the LumaAI API documentation or support for further assistance.
