ComfyUI Node: Vid Dir Iterator

Vid Dir Iterator:

The VidDirIterator is a specialized node designed to facilitate the navigation and retrieval of video files from a specified directory. Its primary purpose is to streamline the process of accessing video files by allowing you to specify search patterns, sorting preferences, and randomization options. This node is particularly beneficial for users who need to manage large collections of video files, as it provides a systematic approach to locate and select videos based on various criteria such as modification date, file name, or size. By leveraging this node, you can efficiently organize and access video content, making it an essential tool for projects that involve video processing or analysis.

Vid Dir Iterator Input Parameters:

directory_path

The directory_path parameter specifies the location of the directory where the video files are stored. It is crucial for the node to know where to look for the video files, and this parameter provides that information. The directory path should be a valid path on your file system. There are no specific minimum or maximum values, but it must be a valid directory path.

glob_patterns

The glob_patterns parameter allows you to define patterns to match specific video files within the directory. This is useful for filtering files based on their extensions or naming conventions. For example, you can use patterns like *.mp4 or *.mov to target specific file types. There are no strict minimum or maximum values, but the patterns should be valid glob patterns.

video_index

The video_index parameter determines which video file to select from the list of files that match the specified patterns. This index is zero-based, meaning an index of 0 corresponds to the first file in the sorted list. The index wraps around using modulo, so it will always return a valid file even if the index exceeds the number of files.

sort_by

The sort_by parameter specifies the criterion used to sort the video files. Options include date_modified, name, size, and random. This parameter affects the order in which files are listed and subsequently selected. The default value is typically date_modified, but you can choose any of the available options based on your needs.

sort_order

The sort_order parameter determines whether the sorting should be in ascending or descending order. This affects how the files are organized after sorting by the specified criterion. The options are ascending or descending, with ascending being the default.

randomize_final_list

The randomize_final_list parameter is a boolean that, when set to true, randomizes the entire list of video files after sorting. This can be useful if you want to introduce an element of randomness in the selection process. The default value is typically false.

Vid Dir Iterator Output Parameters:

video_file_path

The video_file_path output parameter provides the path to the selected video file based on the input criteria. This output is crucial as it allows you to access the specific video file that meets your search and sorting conditions. The path is returned as a string and can be used in subsequent nodes or processes that require video file input.

Vid Dir Iterator Usage Tips:

• Use specific glob_patterns to filter out only the video files you are interested in, which can save time and resources when dealing with large directories.
• Experiment with different sort_by and sort_order settings to organize your video files in a way that best suits your project needs, such as prioritizing the most recently modified files.
• Enable randomize_final_list if you want to introduce variability in your video selection process, which can be particularly useful for creative projects that benefit from randomness.

Vid Dir Iterator Common Errors and Solutions:

No valid video files found in directory

• Explanation: This error occurs when the specified directory does not contain any video files that match the provided glob_patterns.
• Solution: Ensure that the directory_path is correct and that the glob_patterns accurately reflect the file types you are trying to access. Double-check the directory for the presence of video files.

Invalid directory path

• Explanation: This error indicates that the directory_path provided is not a valid path on the file system.
• Solution: Verify that the directory path is correct and accessible. Ensure that there are no typos and that the path exists on your system.

Index out of range

• Explanation: This error can occur if the video_index exceeds the number of available video files.
• Solution: Since the index wraps around using modulo, this error should not occur. However, ensure that the index is within a reasonable range relative to the number of files.
