ComfyUI Node: SequentialImageLoader

SequentialImageLoader:

The VFrame Loader With Mask Editor node is designed to streamline the process of loading and editing video frames with masks for AI art projects. This node allows you to sequentially load images from a directory, making it easier to handle large sets of frames from video files. The integrated mask editor provides a powerful tool for refining and manipulating masks directly within the node, enabling precise control over which parts of the image are affected by subsequent processing steps. This node is particularly useful for tasks that require frame-by-frame editing, such as video inpainting, where maintaining consistency across frames is crucial. By combining frame loading and mask editing in a single node, it simplifies workflows and enhances productivity for AI artists.

SequentialImageLoader Input Parameters:

directory_path

The directory_path parameter specifies the path to the directory containing the video frames you wish to load. This parameter is essential as it tells the node where to find the images. Ensure that the directory contains the frames in a sequential order to maintain the correct sequence during processing.

mask_path

The mask_path parameter indicates the path to the directory or file containing the masks corresponding to the video frames. Masks are used to define areas of interest or exclusion within the frames, and this parameter ensures that the correct masks are applied to the respective frames.

frame_rate

The frame_rate parameter defines the rate at which frames are processed. This is particularly important for synchronizing the frame loading with the intended playback speed of the video. The frame rate should match the original video’s frame rate to ensure consistency.

resize

The resize parameter allows you to specify whether the loaded frames should be resized. This can be useful for reducing the computational load or matching the frames to a specific resolution required by subsequent processing steps. Options typically include boolean values (True/False).

mask_editing_options

The mask_editing_options parameter provides various settings for editing the masks. These options can include tools for drawing, erasing, and refining the masks, allowing for precise control over the mask shapes and areas.

SequentialImageLoader Output Parameters:

frames

The frames output parameter provides the loaded video frames as a sequence of images. These frames can then be used in subsequent nodes for further processing, such as inpainting, color correction, or other image manipulations.

edited_masks

The edited_masks output parameter returns the masks after they have been edited using the mask editor. These masks can be applied to the frames to control which areas are affected by subsequent processing steps, ensuring that the desired regions are accurately targeted.

SequentialImageLoader Usage Tips:

• Ensure that the directory_path and mask_path are correctly set to avoid loading errors.
• Use the frame_rate parameter to match the original video’s frame rate for consistent processing.
• Utilize the mask_editing_options to refine masks precisely, which can significantly improve the quality of the final output.
• Consider resizing frames if working with high-resolution videos to reduce processing time and resource usage.

SequentialImageLoader Common Errors and Solutions:

"Directory not found"

• Explanation: The specified directory_path does not exist or is incorrect.
• Solution: Verify the directory path and ensure it is correctly specified.

"Mask file not found"

• Explanation: The specified mask_path does not exist or is incorrect.
• Solution: Check the mask path and ensure it points to the correct directory or file containing the masks.

"Frame rate mismatch"

• Explanation: The frame_rate parameter does not match the original video’s frame rate, causing synchronization issues.
• Solution: Adjust the frame_rate parameter to match the original video’s frame rate.

"Resize error"

• Explanation: An error occurred while resizing the frames, possibly due to unsupported dimensions.
• Solution: Ensure the resize parameter is set correctly and that the target dimensions are supported by the node.
