ComfyUI Node: Lip Sync Audio Input

Lip Sync Audio Input:

The Lip Sync Audio Input node is designed to facilitate the creation of lip-synced videos by converting audio inputs into synchronized video outputs. This node is part of the KLingAI suite, which leverages advanced AI algorithms to match audio tracks with video content, ensuring that the lip movements in the video align perfectly with the spoken words in the audio. This capability is particularly beneficial for content creators and AI artists who wish to produce engaging and realistic video content without the need for manual synchronization. By using this node, you can streamline the process of generating lip-synced videos, saving time and effort while achieving high-quality results.

Lip Sync Audio Input Input Parameters:

audio_file

The audio_file parameter allows you to specify the path to an audio file that will be used for lip-syncing. This parameter is optional, and if provided, the node will read the audio file, encode it in base64 format, and use it as the input for generating the lip-synced video. The audio file must exist at the specified path; otherwise, an error will be raised. This parameter is useful when you have a local audio file that you want to use for lip-syncing.

audio_url

The audio_url parameter is an optional input that lets you provide a URL to an audio file hosted online. When this parameter is used, the node will fetch the audio from the specified URL and use it for lip-syncing. This is particularly useful when the audio file is not stored locally but is accessible via the internet. It provides flexibility in sourcing audio content for your lip-syncing projects.

Lip Sync Audio Input Output Parameters:

url

The url output parameter provides the URL of the generated lip-synced video. This URL can be used to access and view the video online. It is an essential output as it allows you to retrieve and share the final video product, ensuring that the lip-syncing process has been successfully completed.

video_id

The video_id output parameter returns the unique identifier of the generated video. This ID is crucial for tracking and managing the video within the KLingAI system. It allows you to reference the video in future operations, such as editing or retrieving additional information about the video.

Lip Sync Audio Input Usage Tips:

• Ensure that the audio file path provided in the audio_file parameter is correct and that the file exists to avoid errors during processing.
• When using the audio_url parameter, verify that the URL is accessible and that the audio file is in a supported format to ensure successful lip-syncing.
• Consider the quality and clarity of the audio input, as this can significantly impact the accuracy of the lip-syncing process.

Lip Sync Audio Input Common Errors and Solutions:

Audio file not found: <audio_file>

• Explanation: This error occurs when the specified audio file path does not exist or is incorrect.
• Solution: Double-check the file path to ensure it is correct and that the file exists at the specified location.

Invalid audio URL

• Explanation: This error indicates that the provided audio URL is not accessible or is invalid.
• Solution: Verify that the URL is correct and that the audio file is accessible from the internet. Ensure that the URL points to a valid audio file format.
