ComfyUI Node: 视频插入音频

视频插入音频:

The VideoAddAudio node is designed to seamlessly integrate audio tracks into video files, enhancing your multimedia projects by combining visual and auditory elements. This node is particularly useful for AI artists and creators who want to add background music or sound effects to their video content without the need for complex video editing software. By leveraging the power of ffmpeg, a widely-used multimedia framework, this node efficiently merges audio and video files, ensuring that the final output maintains high quality. The primary goal of this node is to simplify the process of audio insertion, making it accessible to users with minimal technical expertise. It supports popular audio formats like MP3 and WAV, providing flexibility in choosing the right audio track for your video. Overall, VideoAddAudio is an essential tool for enhancing the storytelling and emotional impact of your video projects.

视频插入音频 Input Parameters:

videoPath

The videoPath parameter specifies the file path to the video file into which you want to insert audio. This parameter is crucial as it determines the video content that will be combined with the audio track. The path must be a valid string pointing to an existing video file on your system. There are no default values, and it is mandatory to provide this input for the node to function.

audioPath

The audioPath parameter indicates the file path to the audio file that you wish to add to the video. This parameter is essential for defining the audio content that will accompany the video. The audio file must be in either MP3 or WAV format, as these are the supported formats. Like videoPath, this parameter requires a valid string pointing to an existing audio file, and it is a required input.

filename_prefix

The filename_prefix parameter allows you to specify a prefix for the output file name. This is useful for organizing and identifying your output files, especially when processing multiple videos. The default value for this parameter is "comfyUI", but you can customize it to suit your naming conventions. This parameter is optional, but providing a meaningful prefix can help in managing your output files more effectively.

视频插入音频 Output Parameters:

ui

The ui output parameter provides feedback on the success of the audio insertion process. It includes a text message confirming the successful integration of audio into the video and provides the save path for the output file. Additionally, it contains metadata about the output video, such as the filename, type, and subfolder location. This output is crucial for verifying that the process was completed successfully and for locating the resulting video file.

视频插入音频 Usage Tips:

• Ensure that both the video and audio files exist and are accessible at the specified paths before running the node to avoid errors.
• Use the filename_prefix parameter to organize your output files systematically, especially when working on multiple projects simultaneously.
• Consider the length of the audio file in relation to the video file. If the audio is shorter, it will loop; if longer, it will be truncated to match the video length.

视频插入音频 Common Errors and Solutions:

视频文件不存在

• Explanation: This error occurs when the specified video file path does not exist or is incorrect.
• Solution: Double-check the videoPath to ensure it points to a valid and existing video file.
