ComfyUI Node: ⌨️ CR Load Animation Frames

⌨️ CR Load Animation Frames:

The CR Load Animation Frames node is designed to facilitate the loading of animation frames from a specified directory, enabling you to seamlessly integrate a sequence of images into your animation projects. This node is particularly useful for AI artists who need to process and manipulate a series of frames for animation purposes. By automating the loading process, it saves time and ensures consistency across frames, allowing you to focus on the creative aspects of your work. The node reads images from a directory, converts them into a format suitable for further processing, and returns them as a stack of frames. This functionality is essential for tasks that require frame-by-frame analysis or manipulation, such as video editing, animation creation, and other multimedia projects.

⌨️ CR Load Animation Frames Input Parameters:

image_sequence_folder

This parameter specifies the folder containing the sequence of images to be loaded. It is crucial to ensure that the folder path is correct and accessible, as the node will read the images from this location. The images should be named in a way that allows them to be sorted correctly, typically using a numerical sequence in their filenames.

start_index

This parameter determines the starting index of the frames to be loaded from the specified folder. It allows you to skip a certain number of initial frames if needed. The default value is 1, and it can be adjusted based on your requirements. The minimum value is 1, and there is no strict maximum value, but it should not exceed the total number of frames in the folder.

max_frames

This parameter sets the maximum number of frames to be loaded from the specified folder. It helps in limiting the number of frames processed, which can be useful for performance optimization. The default value is not specified, but it should be set according to the needs of your project. The minimum value is 1, and the maximum value depends on the total number of frames available in the folder.

⌨️ CR Load Animation Frames Output Parameters:

frames

This output parameter returns a stack of loaded frames as a tensor. Each frame is converted to an RGB format and normalized to a range of 0 to 1. The frames are then stacked together, making them ready for further processing or analysis. This output is essential for any subsequent operations that require access to the individual frames of the animation.

show_help

This output parameter provides a URL to the documentation or help page for the node. It is useful for users who need additional information or guidance on how to use the node effectively. The URL points to a wiki page that contains detailed instructions and examples.

⌨️ CR Load Animation Frames Usage Tips:

• Ensure that the image sequence folder path is correct and accessible to avoid errors during the loading process.
• Use the start_index parameter to skip unnecessary initial frames and focus on the relevant part of the animation.
• Adjust the max_frames parameter to limit the number of frames loaded, which can help in optimizing performance and managing memory usage.

⌨️ CR Load Animation Frames Common Errors and Solutions:

The input_path <input_path> does not exist

• Explanation: This error occurs when the specified input path does not exist or is incorrect.
• Solution: Verify that the input path is correct and that the folder exists. Ensure that the path is accessible and properly formatted.

No matching files found for loading

• Explanation: This error indicates that no files matching the expected pattern were found in the specified directory.
• Solution: Check the naming convention of the files in the directory and ensure they match the expected pattern. Verify that the directory contains the correct files.

Error loading image at index <index>

• Explanation: This error occurs when there is an issue loading an image at the specified index.
• Solution: Ensure that the image files are not corrupted and are in a supported format. Verify that the index is within the range of available files.

Insufficient memory to load frames

• Explanation: This error indicates that there is not enough memory available to load the specified number of frames.
• Solution: Reduce the value of the max_frames parameter to load fewer frames at a time. Consider increasing the available memory or optimizing other parts of your workflow to free up resources.
