ComfyUI Node: ImageMaximumNode

ImageMaximumNode:

The ImageMaximumNode is designed to process two video inputs and generate a new video by taking the maximum pixel values from corresponding frames of the input videos. This node is particularly useful in scenarios where you want to combine two video streams and highlight the most prominent features from each. By comparing pixel values, the node ensures that the brightest or most intense pixels are retained in the output, creating a visually striking result. This method is beneficial for enhancing contrast and detail in video compositions, making it a valuable tool for AI artists looking to create dynamic and engaging visual content.

ImageMaximumNode Input Parameters:

video_1

This parameter represents the first video input to the node. It is an image sequence that the node will process to determine the maximum pixel values. The video should be in a compatible format and resolution to ensure accurate processing. The size of this video will be compared with the second video to align dimensions if necessary.

video_2

This parameter is the second video input to the node. Similar to video_1, it is an image sequence that will be compared against the first video to extract maximum pixel values. The node will adjust the dimensions of this video to match video_1 if they differ, ensuring a seamless comparison and output generation.

ImageMaximumNode Output Parameters:

image

The output parameter is an image sequence that represents the result of the maximum pixel value comparison between the two input videos. This output retains the most intense pixel values from each corresponding frame of the input videos, resulting in a composite video that highlights the brightest features from both sources. The output is useful for creating visually compelling video content with enhanced contrast and detail.

ImageMaximumNode Usage Tips:

• Ensure that both input videos have the same resolution to avoid unnecessary interpolation and maintain the quality of the output.
• Use this node to enhance videos with varying lighting conditions by combining them to highlight the best-lit areas.
• Experiment with different video inputs to create unique visual effects by leveraging the maximum pixel value comparison.

ImageMaximumNode Common Errors and Solutions:

Mismatched video dimensions

• Explanation: The input videos have different resolutions, which can lead to errors during processing.
• Solution: Ensure both videos have the same resolution before inputting them into the node, or allow the node to automatically adjust the dimensions by interpolation.

Unsupported video format

• Explanation: The input videos are not in a format that the node can process.
• Solution: Convert the videos to a supported format, such as a standard image sequence, before using them as inputs.

Insufficient memory error

• Explanation: The node requires more memory than is available to process high-resolution videos.
• Solution: Reduce the resolution of the input videos or increase the available memory resources to accommodate the processing requirements.
