ComfyUI Node: 🎬 Veo 3.1 4K Upscale

🎬 Veo 3.1 4K Upscale:

The Veo314KUpscale node is designed to enhance the resolution of videos generated by the Veo 3.1 system to 4K quality. This node is particularly beneficial for users who have previously created videos using Veo 3.1 and wish to improve their visual clarity and detail. By leveraging advanced upscaling techniques, this node ensures that your videos are transformed into high-definition outputs, making them suitable for professional presentations, cinematic experiences, or any application where high resolution is paramount. The process is streamlined and user-friendly, requiring only a few inputs to achieve impressive results.

🎬 Veo 3.1 4K Upscale Input Parameters:

api_key

The api_key is a required string parameter that serves as your authentication credential for accessing the Veo 3.1 API. It is crucial for verifying your identity and ensuring that you have the necessary permissions to perform the upscale operation. The api_key must be a valid, non-empty string, and there is no default value provided. Without a valid api_key, the node will not be able to execute the upscale process.

request_id

The request_id is a required string parameter that identifies the specific video generation request you wish to upscale. This ID is obtained from a previous Veo 3.1 video generation process. It is essential for the node to locate and process the correct video for upscaling. The request_id must be a valid, non-empty string, and there is no default value provided. Providing an incorrect or empty request_id will result in an error.

extra_params_json

The extra_params_json is an optional string parameter that allows you to pass additional configuration options in JSON format. This parameter can be used to customize the upscaling process further, although it defaults to an empty JSON object ({}). The parameter is multiline, enabling you to include complex configurations if needed. While not mandatory, using this parameter can provide more control over the upscaling process.

🎬 Veo 3.1 4K Upscale Output Parameters:

video_url

The video_url is a string output that provides the CDN URL of the 4K upscaled video. This URL allows you to access and download the enhanced video directly from the content delivery network, ensuring fast and reliable access to your high-resolution content.

first_frame

The first_frame is an image output that offers a preview of the first frame of the upscaled video. This visual snapshot helps you quickly verify the quality and content of the video without needing to download or view the entire file.

new_request_id

The new_request_id is a string output that represents a new request identifier for the upscaling operation. This ID can be used for tracking the status of the upscale process or for further operations within the Veo 3.1 system.

🎬 Veo 3.1 4K Upscale Usage Tips:

• Ensure that your api_key is valid and correctly entered to avoid authentication errors.
• Double-check the request_id to make sure it corresponds to the correct video you wish to upscale.
• Utilize the extra_params_json to fine-tune the upscaling process if you have specific requirements or preferences.

🎬 Veo 3.1 4K Upscale Common Errors and Solutions:

api_key is required.

• Explanation: This error occurs when the api_key parameter is missing or empty.
• Solution: Provide a valid api_key to authenticate your request and enable the upscaling process.

request_id is required.

• Explanation: This error indicates that the request_id parameter is missing or empty, preventing the node from identifying the video to upscale.
• Solution: Ensure that you provide a valid request_id from a previous Veo 3.1 video generation to proceed with the upscaling.
