ComfyUI Node: LUMA_generator @.@

LUMA_generator @.@:

The LUMA_API_YoC node is designed to facilitate the generation of cinematic videos using the Luma Labs API. This node allows you to input specific text prompts and optionally download the generated video directly to your local system. The primary goal of this node is to streamline the process of creating visually appealing video content by leveraging the capabilities of Luma Labs' advanced video generation technology. By using this node, you can easily integrate video generation into your creative workflows, making it an invaluable tool for AI artists looking to enhance their projects with high-quality video outputs.

LUMA_generator @.@ Input Parameters:

text

This parameter represents the text prompt that will be used to generate the video. The text should be descriptive and relevant to the type of video content you wish to create. The quality and relevance of the generated video are highly dependent on the clarity and specificity of the text prompt provided. There are no strict minimum or maximum values for this parameter, but it is recommended to use concise and meaningful descriptions to achieve the best results.

download

This is a boolean parameter that determines whether the generated video should be downloaded to your local system. If set to True, the video will be saved in the specified output folder. The default value for this parameter is True. Setting this parameter to False will prevent the video from being downloaded, which can be useful if you only need the video link for further processing or sharing.

LUMA_generator @.@ Output Parameters:

video_link

This output parameter provides the link to the generated video. The link can be used to access the video online or for further processing in other nodes or applications. The video link is a string that points to the location of the generated video on the Luma Labs server. This output is crucial for retrieving and utilizing the video content created based on the provided text prompt.

LUMA_generator @.@ Usage Tips:

• Ensure that your text prompt is clear and descriptive to achieve the best video generation results. Avoid vague or overly complex descriptions.
• Use the download parameter wisely based on your needs. If you plan to use the video immediately, set download to True to save time.
• Organize your output folder to keep track of generated videos, especially if you are creating multiple videos in a single session.

LUMA_generator @.@ Common Errors and Solutions:

Error: Cookie is required. Please enter correct cookie in key.json

• Explanation: This error occurs when the API key (cookie) is not found or is incorrect in the key.json file.
• Solution: Ensure that the key.json file is present in the correct directory and contains the valid API key under the "cookie" field.

Error: Fail to create the folder: <error_message>

• Explanation: This error indicates that the node was unable to create the specified output folder, possibly due to permission issues or an invalid path.
• Solution: Check the folder path and ensure that you have the necessary permissions to create directories in the specified location. Adjust the path if necessary.

Error: Empty Image

• Explanation: This error is triggered when the provided image tensor is detected to be empty or nearly empty, which means it lacks sufficient content for processing.
• Solution: Verify that the input image is correctly loaded and contains meaningful content. Adjust the image preprocessing steps if needed to ensure a valid image tensor is provided.
