ComfyUI Node: 🔥AddAudio

🔥AddAudio:

The AddAudio node is designed to seamlessly integrate audio tracks into video files, providing a powerful tool for enhancing multimedia projects. This node leverages the capabilities of FFmpeg to add audio from either an audio file or another video file to a specified video. By allowing you to specify the source of the audio and the timing for its introduction, the AddAudio node offers flexibility and control over the final output. This functionality is particularly beneficial for AI artists and multimedia creators who wish to synchronize audio with video content, create dynamic presentations, or enhance the auditory experience of their projects. The node's ability to handle different file types and manage output paths ensures that users can efficiently produce high-quality video content with integrated audio.

🔥AddAudio Input Parameters:

video_path

This parameter specifies the path to the video file to which you want to add audio. It is crucial as it determines the primary video content that will be modified. The default value is set to "C:/Users/Desktop/video.mp4", and it accepts a string representing the file path.

audio_from

This parameter allows you to choose the source of the audio to be added to the video. You can select between "audio_file" and "video_file", with the default being "audio_file". This choice impacts whether the audio is extracted from a standalone audio file or another video file.

file_path

This parameter defines the path where the audio file is located if you are adding audio from an audio file. It is essential for locating the correct audio content to integrate into the video. The default value is "C:/Users/Desktop/output".

delay_play

This parameter sets the delay in seconds before the audio starts playing in the video. It allows for precise synchronization of audio and video, ensuring that the audio begins at the desired moment. The default value is 0, with a minimum of 0, indicating no delay.

output_path

This parameter specifies the directory where the final video with the added audio will be saved. It is important for organizing and accessing the output file. The default value is "C:/Users/Desktop/output/", and it accepts a string representing the directory path.

🔥AddAudio Output Parameters:

video_complete_path

This output parameter provides the complete path to the newly created video file with the added audio. It is a string that indicates where the final video is stored, allowing you to easily locate and use the output in further projects or presentations.

🔥AddAudio Usage Tips:

• Ensure that the video_path and file_path are correctly specified to avoid errors in locating the files.
• Use the delay_play parameter to synchronize audio with specific video events, enhancing the overall viewing experience.
