ComfyUI Node: LoadVideo

LoadVideo:

The LoadVideo node is designed to facilitate the loading of video files into your AI animation workflow. This node allows you to select a video from a specified directory and processes it to extract both the video and its associated audio, if available. By leveraging this node, you can seamlessly integrate video content into your projects, enabling a more dynamic and multimedia-rich experience. The primary function of this node is to read video files in various formats and prepare them for further processing or analysis within your AI-driven animation pipeline.

LoadVideo Input Parameters:

video

The video parameter allows you to select a video file from a predefined directory. This parameter lists all available video files in formats such as MP4, WEBM, MKV, and AVI. The selected video file will be loaded and processed by the node. The function of this parameter is to specify which video file you want to work with, and it directly impacts the node's execution by determining the source content. There are no minimum or maximum values for this parameter, but it is essential to ensure that the video file exists in the specified directory and is in one of the supported formats.

LoadVideo Output Parameters:

VIDEO

The VIDEO output parameter provides the path to the loaded video file. This output is crucial as it serves as the reference to the video content that can be used in subsequent nodes or processes within your animation workflow. The value of this parameter is the file path of the selected video.

AUDIO

The AUDIO output parameter provides the path to the extracted audio file from the loaded video. If the video contains an audio track, this parameter will hold the path to the audio file saved in WAV format. This output is important for scenarios where you need to work with the audio separately or synchronize it with other elements in your project. If the video does not contain audio, this parameter may not be generated.

LoadVideo Usage Tips:

• Ensure that your video files are placed in the specified input directory and are in one of the supported formats (MP4, WEBM, MKV, AVI) to avoid any issues with file selection.
• Use the VIDEO output parameter to reference the video file in subsequent nodes, enabling you to build complex workflows that incorporate video content.
• If your project requires audio processing, make sure to check the AUDIO output parameter to verify that the audio track has been successfully extracted.

LoadVideo Common Errors and Solutions:

FileNotFoundError

• Explanation: This error occurs when the specified video file is not found in the input directory.
• Solution: Ensure that the video file exists in the input directory and that the file name is correctly specified.

UnsupportedFormatError

• Explanation: This error occurs when the selected video file is in an unsupported format.
• Solution: Verify that the video file is in one of the supported formats (MP4, WEBM, MKV, AVI) and try again.

NoAudioError

• Explanation: This error occurs when the video file does not contain an audio track, and the node attempts to extract audio.
• Solution: If your workflow requires audio, ensure that the video file includes an audio track. If audio is not needed, you can ignore this error.

PermissionError

• Explanation: This error occurs when the node does not have the necessary permissions to read the video file or write the audio file.
• Solution: Check the file permissions and ensure that the node has the appropriate read and write access to the input directory and files.
