ComfyUI Node: Load Frame Sequence

Load Frame Sequence:

The LoadFrameSequence node is designed to streamline the process of loading a sequence of image frames from a specified directory. This node is particularly useful for AI artists working with video frames or image sequences, as it automates the task of gathering all frames from a given path, making them readily available for further processing or analysis. By leveraging this node, you can efficiently manage and utilize large sets of frames, ensuring that all images are correctly loaded and accessible. The primary function of this node is to search through the specified directory, recursively gather all image files, and return them along with the total count of frames found. This capability is essential for workflows involving animation, video editing, or any project requiring sequential image data.

Load Frame Sequence Input Parameters:

file_path

The file_path parameter specifies the directory path where the image frames are located. This parameter accepts a string input, which can be multiline to accommodate complex paths. The default value is set to C:\\code\\warp\\19_cn_venv\\images_out\\stable_warpfusion_0.20.0\\videoFrames\\650571deef_0_0_1. The function of this parameter is to guide the node to the correct location for frame retrieval. It is crucial to ensure that the path is accurate and accessible, as an incorrect path will result in no frames being found. This parameter does not have minimum or maximum values but must be a valid directory path.

Load Frame Sequence Output Parameters:

Frames

The Frames output parameter is a list of dictionaries, where each dictionary contains information about an individual frame. Specifically, each dictionary includes the path to the image file and the total number of frames. This output is essential for subsequent nodes or processes that require access to the individual frames for tasks such as image processing, animation, or analysis.

Total_frames

The Total_frames output parameter provides an integer value representing the total number of frames found in the specified directory. This output is important for understanding the scope of the frame sequence and for any operations that need to iterate over the entire set of frames. It ensures that you have a clear count of the available frames, which can be used for indexing or looping purposes.

Load Frame Sequence Usage Tips:

• Ensure that the file_path parameter is correctly set to the directory containing your image frames. Double-check the path for any typos or errors to avoid issues with frame loading.
• Use the Total_frames output to manage loops or iterations over the frame sequence, ensuring that you do not exceed the available number of frames.
• Combine this node with other nodes that process or analyze images to create a comprehensive workflow for handling video frames or image sequences.

Load Frame Sequence Common Errors and Solutions:

Found 0 frames in path <file_path>

• Explanation: This error occurs when the specified directory does not contain any image files or the path is incorrect.
• Solution: Verify that the file_path parameter is correct and that the directory contains image files. Ensure that the path is accessible and properly formatted.

Invalid file path

• Explanation: This error indicates that the provided file_path is not a valid directory path.
• Solution: Check the file_path for any typos or errors. Make sure that the path points to an existing directory and is correctly formatted.

Permission denied

• Explanation: This error occurs when the node does not have the necessary permissions to access the specified directory.
• Solution: Ensure that the directory permissions allow read access for the user running the node. Adjust the permissions if necessary or run the node with appropriate privileges.
