ComfyUI Node: Load Audio Path From Video

Load Audio Path From Video:

The Load_Audio_Path_From_Video node is designed to extract the audio track from a video file and save it as an MP3 file. This node is particularly useful for AI artists who need to work with audio data extracted from video content. By automating the extraction process, it saves time and ensures that the audio is correctly separated from the video. The node leverages the powerful ffmpeg tool to perform the extraction, ensuring high-quality audio output. This functionality is essential for tasks that require audio analysis, manipulation, or synchronization with other media elements.

Load Audio Path From Video Input Parameters:

video_path

The video_path parameter specifies the path to the video file from which the audio will be extracted. This parameter accepts a list of video files available in the input directory, supporting formats such as MP4, WEBM, MKV, and AVI. The selected video file should contain an audio track for the extraction to be successful. The function of this parameter is to identify the source video file, and its impact on the node's execution is crucial as it determines the audio content to be extracted. There are no minimum or maximum values for this parameter, but it must be a valid video file path.

Load Audio Path From Video Output Parameters:

AUDIO_PATH

The AUDIO_PATH output parameter provides the path to the extracted audio file. This parameter returns the file path of the MP3 audio file that has been generated from the input video. The importance of this output lies in its use for subsequent audio processing tasks. The output value is a string representing the file path, which can be used to locate and utilize the extracted audio in further workflows.

Load Audio Path From Video Usage Tips:

• Ensure that the video file you select contains an audio track, as the extraction process relies on the presence of audio data.
• Verify that the input directory is correctly set and contains the video files you intend to use for audio extraction.
• Use the extracted audio file path in subsequent nodes or processes that require audio input, such as audio analysis or synchronization tasks.

Load Audio Path From Video Common Errors and Solutions:

<audio_path> not exists! Please check if the video contains audio!`

• Explanation: This error occurs when the specified audio file does not exist after the extraction process, indicating that the video may not contain an audio track.
• Solution: Ensure that the selected video file has an audio track. You can check the video file properties or play the video to confirm the presence of audio before using it in the node.

ffmpeg not found

• Explanation: This error indicates that the ffmpeg executable is not found in the system path, which is required for the audio extraction process.
• Solution: Install ffmpeg and ensure it is added to the system path. You can download ffmpeg from the official website and follow the installation instructions for your operating system.
