ComfyUI Node: Save Image Sequence (mtb)

Save Image Sequence (mtb):

The Save Image Sequence (mtb) node is designed to facilitate the saving of a series of images to a specified folder, with each image being saved as a separate file. This node is particularly useful for AI artists who need to export frames from animations or sequences of generated images. By automating the process of saving each image with a consistent naming convention and optional metadata, this node streamlines the workflow and ensures that all images are organized and easily accessible. The node leverages the save_images function to handle the actual saving process, including the formatting of the output folder and filenames.

Save Image Sequence (mtb) Input Parameters:

images

This parameter expects a list of images that you want to save. Each image in the list will be processed and saved as an individual file. The images should be in a format that is compatible with the node's processing capabilities.

filename_prefix

This parameter allows you to specify a prefix for the filenames of the saved images. The default value is "Sequence". This prefix will be used to generate the filenames, ensuring that each file is uniquely named and easily identifiable. For example, if the prefix is "Frame", the saved files might be named "Frame_00001.png", "Frame_00002.png", and so on.

current_frame

This parameter indicates the starting frame number for the sequence. The default value is 0, and it can range from 0 to 9999999. This number will be appended to the filename prefix to create unique filenames for each image in the sequence. For instance, if the current frame is set to 5, the filenames might be "Sequence_00005.png", "Sequence_00006.png", etc.

Save Image Sequence (mtb) Output Parameters:

This node does not produce any direct output parameters. Its primary function is to save the provided images to the specified directory with the appropriate filenames and metadata.

Save Image Sequence (mtb) Usage Tips:

• Ensure that the images parameter contains a valid list of images to avoid errors during the saving process.
• Use a meaningful filename_prefix to make it easier to identify and organize the saved images.
• Adjust the current_frame parameter if you need to start the sequence from a specific frame number, especially when continuing a previously saved sequence.

Save Image Sequence (mtb) Common Errors and Solutions:

"Invalid image list"

• Explanation: This error occurs when the images parameter does not contain a valid list of images.
• Solution: Ensure that you provide a list of images in the images parameter. Verify that the images are in a compatible format.

"Output directory not found"

• Explanation: This error occurs when the specified output directory does not exist.
• Solution: Check the output directory path and ensure that it exists. You may need to create the directory manually if it does not exist.

"Filename prefix is invalid"

• Explanation: This error occurs when the filename_prefix contains invalid characters or is not specified.
• Solution: Ensure that the filename_prefix is a valid string without any special characters that are not allowed in filenames.
