ComfyUI Node: Combine Audio Video

Combine Audio Video:

The CombineAudioVideo node is designed to seamlessly merge an audio file with a video file, creating a single output that combines both media elements. This node is particularly useful for AI artists who want to add background music, voiceovers, or any other audio tracks to their video projects without needing to use complex video editing software. By automating the process of combining audio and video, this node saves time and effort, allowing you to focus on the creative aspects of your work. The node ensures that the audio and video are synchronized correctly, providing a professional-quality output.

Combine Audio Video Input Parameters:

video_file_path

This parameter specifies the path to the video file that you want to combine with an audio track. It is a required input and must be provided as a string. The video file should be in a format supported by ffmpeg, such as MP4, MKV, or WEBM. The correct path ensures that the node can locate and process the video file accurately.

audio_file_path

This parameter specifies the path to the audio file that you want to merge with the video. It is also a required input and must be provided as a string. The audio file should be in a format supported by ffmpeg, such as WAV, MP3, or AAC. Providing the correct path ensures that the node can locate and process the audio file accurately.

Combine Audio Video Output Parameters:

This node does not have explicit output parameters defined in the RETURN_TYPES. However, it generates a combined audio-video file and provides a preview of the output. The output file is saved in the specified output directory with a unique filename to avoid overwriting existing files.

Combine Audio Video Usage Tips:

• Ensure that both the video and audio files are in formats supported by ffmpeg to avoid compatibility issues.
• Use descriptive filenames for your input files to easily identify them during the combination process.
• Verify the synchronization of audio and video in the output file to ensure that they are aligned as intended.
