ComfyUI Node: PreViewVideo

PreViewVideo:

The PreViewVideo node is designed to facilitate the previewing of video files within the RealisDance-ComfyUI framework. Its primary function is to extract and present metadata about a video file, specifically its name and the directory it resides in. This node is particularly useful for users who need to quickly identify and manage video files within their projects, providing a straightforward way to access essential information without delving into the file system. By offering a simple interface to retrieve video details, PreViewVideo enhances the workflow efficiency for AI artists working with video data, allowing them to focus more on creative tasks rather than technical file management.

PreViewVideo Input Parameters:

video

The video parameter is the sole input for the PreViewVideo node, and it expects a video file as its input. This parameter is crucial as it determines which video file's metadata will be extracted and displayed. The function of this parameter is to provide the node with the necessary data to perform its operation, which is to retrieve and present the video's name and directory path. There are no specific minimum, maximum, or default values for this parameter, as it simply requires a valid video file path to function correctly. The impact of this parameter on the node's execution is direct, as the node's output is entirely dependent on the video file provided.

PreViewVideo Output Parameters:

The PreViewVideo node does not produce any direct output parameters in the traditional sense, as indicated by the empty RETURN_TYPES. However, it indirectly provides output by returning a dictionary containing the video's name and directory path. This information is crucial for users who need to verify or manage video files within their projects, as it allows them to quickly identify the file's location and name without manually searching through directories. The output is presented in a user-friendly format, making it easy for users to interpret and utilize the information in their workflow.

PreViewVideo Usage Tips:

• Ensure that the video file path provided to the video parameter is correct and accessible to avoid any issues with retrieving the file's metadata.
• Use the PreViewVideo node as a preliminary step in your workflow to verify video file details before proceeding with more complex operations or processing tasks.

PreViewVideo Common Errors and Solutions:

FileNotFoundError
