ComfyUI Node: Lip Sync

Lip Sync:

The Lip Sync node is designed to seamlessly synchronize audio with video, providing a powerful tool for creating engaging multimedia content. This node leverages advanced AI capabilities to match spoken words or audio tracks with corresponding video footage, ensuring that the lip movements in the video align perfectly with the audio. This feature is particularly beneficial for content creators looking to enhance their videos with accurate and realistic lip-syncing, whether for dubbing, animation, or virtual character creation. By utilizing the Lip Sync node, you can achieve professional-grade synchronization, enhancing the overall quality and impact of your video projects.

Lip Sync Input Parameters:

client

The client parameter represents the KLingAI API client instance required to interact with the Lip Sync service. It is essential for authenticating and managing requests to the API, ensuring that the node can perform its operations effectively.

video_id

The video_id parameter is a string that uniquely identifies the video to which the lip-syncing will be applied. This ID is crucial for specifying the target video within the KLingAI system, allowing the node to accurately synchronize the audio with the correct video content.

input

The input parameter is of type KLING_AI_API_LIPSYNC_INPUT and contains all the necessary information for the lip-syncing process. This includes details such as the mode of operation (e.g., text2video or audio2video), the audio source (file or URL), and other relevant settings. This parameter is central to configuring the lip-sync operation and ensuring that the desired synchronization is achieved.

Lip Sync Output Parameters:

url

The url output parameter provides the URL of the processed video after the lip-sync operation is complete. This URL allows you to access and view the synchronized video, making it easy to share or download the final product.

video_id

The video_id output parameter returns the unique identifier of the processed video. This ID is useful for tracking and managing the video within the KLingAI system, especially if further modifications or retrievals are needed.

Lip Sync Usage Tips:

• Ensure that the client parameter is correctly configured with valid credentials to avoid authentication issues when accessing the KLingAI API.
• When using the audio2video mode, verify that the audio file path is correct and the file is accessible to prevent file not found errors.
• Adjust the voice_speed parameter to fine-tune the synchronization speed, especially when working with different languages or speech patterns.

Lip Sync Common Errors and Solutions:

Audio file not found: <audio_file>

• Explanation: This error occurs when the specified audio file path is incorrect or the file is not accessible.
• Solution: Double-check the file path and ensure that the file exists and is readable by the system.

Invalid client configuration

• Explanation: This error indicates that the KLingAI API client is not properly configured, leading to authentication failures.
• Solution: Verify that the client is set up with the correct API credentials and network settings.

Unsupported audio type

• Explanation: This error arises when an unsupported audio type is specified in the input parameters.
• Solution: Ensure that the audio type is either file or url and that the corresponding audio source is valid.
