ComfyUI Node: PreView Video

PreView Video:

The PreViewVideo node is designed to facilitate the previewing of video files within the MiniCPM-V framework. This node is particularly useful for AI artists who need to quickly and easily load and view video content as part of their creative workflow. By providing a straightforward method to load video files, PreViewVideo helps streamline the process of integrating video assets into your projects, allowing you to focus more on the creative aspects rather than the technical details of video handling. The node extracts the video file's name and its directory path, making it accessible for further processing or display in the user interface.

PreView Video Input Parameters:

video

This parameter expects a video file that has been loaded into the system. The input type is specified as "VIDEO", which means it should be a video file that has been previously loaded using a compatible node like LoadVideo. The video parameter is essential as it provides the path to the video file that you want to preview. There are no specific minimum, maximum, or default values for this parameter, but it must be a valid video file path.

PreView Video Output Parameters:

This node does not produce any direct output parameters in the traditional sense. Instead, it generates a UI element that allows you to preview the video. The output is structured as a dictionary containing the video file's name and its directory path, which is then used to display the video in the user interface.

PreView Video Usage Tips:

• Ensure that the video file you want to preview has been correctly loaded using the LoadVideo node before connecting it to the PreViewVideo node.
• Use this node to quickly verify the content and quality of your video files before proceeding with more complex processing tasks.
• This node is particularly useful in workflows where visual verification of video content is necessary, such as in video editing or AI-driven video analysis projects.

PreView Video Common Errors and Solutions:

"Invalid video file path"

• Explanation: This error occurs when the provided video file path is not valid or the file does not exist in the specified directory.
• Solution: Ensure that the video file has been correctly loaded using the LoadVideo node and that the file path is accurate.

"Unsupported video format"

• Explanation: This error is triggered when the video file format is not supported by the node.
• Solution: Make sure that the video file is in one of the supported formats such as mp4, webm, mkv, or avi.

"Video file not found"

• Explanation: This error indicates that the video file specified cannot be found in the input directory.
• Solution: Verify that the video file exists in the input directory and that the file name is correctly specified.

"Failed to load video"

• Explanation: This error occurs when there is an issue with loading the video file, possibly due to file corruption or incompatible codecs.
• Solution: Check the integrity of the video file and ensure it is not corrupted. Try re-encoding the video using a different codec if necessary.
