ComfyUI Node: SaveVideoPath

SaveVideoPath:

The SaveVideoPath node is designed to facilitate the saving of video files by generating and returning the complete file path where the video is stored. This node is particularly useful for AI artists who need to manage and organize their video outputs efficiently. By automating the path generation process, it ensures that videos are saved with a consistent naming convention and in a specified directory, which can be crucial for maintaining an organized workflow. The node also supports various video formats and codecs, allowing for flexibility in how videos are saved. Additionally, it can append metadata to the saved video, which can include prompts or additional information, enhancing the video file's utility for future reference or processing.

SaveVideoPath Input Parameters:

video

This parameter represents the video file that you wish to save. It is essential for the node's operation as it provides the content that will be written to the disk. The video input must be in a compatible format that the node can process.

filename_prefix

The filename_prefix is a string that serves as the initial part of the saved video's filename. By default, it is set to "video/ComfyUI". This prefix helps in categorizing and identifying the video files, making it easier to locate them later. You can customize this prefix to suit your organizational needs.

format

The format parameter specifies the video format in which the file will be saved. It defaults to "auto", allowing the node to automatically determine the most suitable format based on the input video. This flexibility ensures compatibility with various playback devices and software.

codec

The codec parameter determines the video encoding method used during the saving process. Like the format, it defaults to "auto", enabling the node to select an appropriate codec automatically. This ensures that the video is saved efficiently, balancing quality and file size.

SaveVideoPath Output Parameters:

path

The path output parameter provides the complete file path where the video has been saved. This string is crucial for accessing the video file later, as it includes the directory and filename, ensuring you can easily locate and use the saved video.

SaveVideoPath Usage Tips:

• Customize the filename_prefix to include project-specific identifiers, which can help in organizing and retrieving videos more efficiently.
• Utilize the format and codec parameters set to "auto" for general use, but specify them explicitly if you have particular requirements for video quality or compatibility.
• Consider appending metadata to your videos if you need to store additional information, such as prompts or processing details, which can be useful for future reference.

SaveVideoPath Common Errors and Solutions:

Invalid video file

• Explanation: This error occurs when the input video file is not recognized or is in an unsupported format.
• Solution: Ensure that the video file is correctly formatted and compatible with the node's requirements. Convert the video to a supported format if necessary.

File path not found

• Explanation: This error indicates that the specified output directory does not exist or is inaccessible.
• Solution: Verify that the output directory is correctly specified and that you have the necessary permissions to write to it. Create the directory if it does not exist.

Metadata saving error

• Explanation: This error can occur if there is an issue with appending metadata to the video file.
• Solution: Check the metadata format and ensure it is correctly structured. If the problem persists, try saving the video without metadata to isolate the issue.
