ComfyUI Node: Make Frame Dataset

Make Frame Dataset:

The MakeFrameDataset node is designed to create a dataset of frames from a specified directory, which can be used for various AI art and video processing tasks. This node is particularly useful for artists and developers working with frame-based animations or video sequences, as it simplifies the process of loading and managing frames. By specifying a directory path, the node will gather all the frames within that directory and prepare them for further processing. This functionality is essential for workflows that involve frame-by-frame manipulation, such as stylization, animation, or video editing. The node also provides an option to update the dataset dynamically as new frames are loaded, ensuring that the dataset remains current with any changes in the source directory.

Make Frame Dataset Input Parameters:

file_path

This parameter specifies the directory path where the frames are stored. It should be a string value, and you can input the path directly. The default value is set to C:\\code\\warp\\19_cn_venv\\images_out\\stable_warpfusion_0.20.0\\videoFrames\\650571deef_0_0_1. This path should point to a folder containing the frames you wish to include in your dataset. Ensure that the path is correct and accessible to avoid any issues during execution.

update_on_frame_load

This boolean parameter determines whether the dataset should be updated dynamically as new frames are loaded. The default value is set to True. When enabled, the dataset will refresh and include any new frames added to the directory, ensuring that the dataset remains up-to-date. If set to False, the dataset will only include the frames present at the time of the initial load.

Make Frame Dataset Output Parameters:

FRAME_DATASET

This output parameter represents the dataset of frames created from the specified directory. It is an object that contains all the frames and can be used in subsequent nodes for further processing. The dataset is essential for workflows that require access to individual frames for tasks such as animation, stylization, or video editing.

Total_frames

This output parameter indicates the total number of frames included in the dataset. It is an integer value that provides a quick reference to the size of the dataset. Knowing the total number of frames is useful for managing and iterating through the dataset in subsequent processing steps.

Make Frame Dataset Usage Tips:

• Ensure that the file_path parameter points to a valid directory containing the frames you wish to use. Double-check the path for any typos or errors.
• If you are working with a dynamic set of frames that may change over time, set the update_on_frame_load parameter to True to keep the dataset current with any new frames added to the directory.
• Use the Total_frames output to manage and iterate through the dataset effectively, especially when working with large sets of frames.

Make Frame Dataset Common Errors and Solutions:

Found 0 frames in path <file_path>

• Explanation: This error occurs when the specified directory does not contain any frames or the path is incorrect.
• Solution: Verify that the file_path parameter is correct and points to a directory containing frames. Ensure that the directory is accessible and contains the expected frame files.

Frame source not found at <source_path>

• Explanation: This error occurs when the specified source path does not exist.
• Solution: Check the file_path parameter to ensure it points to an existing directory. Correct any typos or errors in the path.

<source_path> is a file. Please specify path to a folder.

• Explanation: This error occurs when the specified path is a file instead of a directory.
• Solution: Ensure that the file_path parameter points to a directory containing frames, not a single file. Adjust the path accordingly.
