ComfyUI Node: Interpolate Generations

Interpolate Generations:

LumaInterpolateGenerations is a powerful node designed to create a seamless video by interpolating between two existing video generations. This node leverages the capabilities of the LumaAI API to generate smooth transitions between two specified video frames, identified by their unique generation IDs. The primary benefit of this node is its ability to produce high-quality interpolated videos that can be used in various creative projects, such as animations, video effects, and artistic visualizations. By providing a prompt and the IDs of the two generations, you can generate a video that smoothly transitions from one generation to the other, enhancing the visual storytelling and dynamic content creation.

Interpolate Generations 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 interpolation process. It helps define the context or theme of the video being generated. The prompt should be clear and descriptive to achieve the desired interpolation effect.

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.

generation_id_1

The unique identifier of the first generation. This ID is required to specify the starting point of the interpolation. It must be a valid generation ID obtained from a previous video generation.

generation_id_2

The unique identifier of the second generation. This ID is required to specify the ending point of the interpolation. It must be a valid generation ID obtained from a previous video generation.

filename

An optional parameter that specifies the name of the file where the video will be saved. If not provided, the generation ID will be used as the filename. This parameter is only relevant if save is set to True.

Interpolate Generations Output Parameters:

ui

This output parameter provides a dictionary containing UI-related information. It includes the generation ID in a text format, which can be used for display purposes or further processing.

result

The result parameter is a tuple containing the URL of the generated video and the generation ID. The video URL can be used to view or download the interpolated video, while the generation ID can be used for reference or further API interactions.

Interpolate Generations Usage Tips:

• Ensure that both generation_id_1 and generation_id_2 are valid and correspond to existing video generations to avoid errors.
• Use a clear and descriptive prompt to guide the interpolation process effectively and achieve the desired visual effect.
• If you want to save the generated video locally, set the save parameter to True and provide a meaningful filename to organize your files better.

Interpolate Generations Common Errors and Solutions:

Both generation IDs are required

• Explanation: This error occurs when either generation_id_1 or generation_id_2 is not provided.
• Solution: Ensure that both generation_id_1 and generation_id_2 are specified and are valid generation IDs.

Generation failed: <failure_reason>

• Explanation: This error indicates that the video generation process failed due to a specific reason provided by the API.
• Solution: Check the failure reason provided in the error message and address the issue accordingly. It could be due to an invalid prompt, network issues, or other API-related problems.

You must provide at least one generation id

• Explanation: This error occurs when neither init_generation_id nor final_generation_id is provided.
• Solution: Ensure that at least one of the generation IDs is specified to proceed with the video generation.

You cannot provide both an init image and an init generation

• Explanation: This error occurs when both init_image_url and init_generation_id are provided simultaneously.
• Solution: Provide only one of the parameters, either init_image_url or init_generation_id, to avoid conflicts.

You cannot provide both a final image and a final generation

• Explanation: This error occurs when both final_image_url and final_generation_id are provided simultaneously.
• Solution: Provide only one of the parameters, either final_image_url or final_generation_id, to avoid conflicts.
