ComfyUI Node: Stability Conservative Upscale

Stability Conservative Upscale:

The Stability Conservative Upscale node is designed to enhance the resolution of your images while maintaining their original quality and details. This node is particularly useful for AI artists who want to upscale their images without introducing significant alterations or artifacts. By leveraging advanced algorithms, the node ensures that the upscaled image retains the essence and integrity of the original, making it ideal for applications where preserving the original look is crucial. This method is conservative in nature, meaning it focuses on subtle enhancements rather than dramatic changes, providing a balanced approach to image upscaling.

Stability Conservative Upscale Input Parameters:

image

This parameter requires the input image that you want to upscale. The image should be provided in a supported format such as PNG, JPEG, or WEBP. The quality and resolution of the input image will directly impact the results of the upscaling process.

prompt

The prompt is a textual description that guides the upscaling process. It can be a detailed description of the image content or specific elements you want to emphasize during upscaling. This parameter supports multiline input, allowing for comprehensive descriptions.

negative_prompt

The negative prompt is an optional parameter that allows you to specify elements or features you want to avoid during the upscaling process. This can help in refining the output by excluding unwanted details. This parameter also supports multiline input.

seed

The seed parameter is an integer value used to initialize the random number generator for the upscaling process. By setting a specific seed, you can achieve reproducible results. The default value is 0, with a minimum of 0 and a maximum of 4294967294.

creativity

The creativity parameter controls the level of creative freedom the algorithm has during the upscaling process. It is a float value ranging from 0.2 to 0.5, with a default value of 0.35. Higher values allow for more creative alterations, while lower values focus on preserving the original image details.

output_format

This parameter specifies the format of the output image. You can choose from PNG, WEBP, or JPEG. The choice of format can affect the file size and quality of the upscaled image.

api_key_override

The api_key_override is an optional string parameter that allows you to specify a different API key for the upscaling process. This can be useful if you have multiple API keys and want to use a specific one for this operation.

Stability Conservative Upscale Output Parameters:

image

The output parameter is the upscaled image. This image will have a higher resolution than the input image while maintaining the original quality and details. The format of the output image will be as specified in the output_format parameter.

Stability Conservative Upscale Usage Tips:

• Use a detailed prompt to guide the upscaling process effectively, ensuring that important elements are emphasized.
• Adjust the creativity parameter based on your needs; lower values for minimal changes and higher values for more creative enhancements.
• Experiment with different seed values to explore various upscaling outcomes and find the one that best suits your requirements.

Stability Conservative Upscale Common Errors and Solutions:

"Invalid image format"

• Explanation: The input image is not in a supported format.
• Solution: Ensure that the input image is in PNG, JPEG, or WEBP format.

"Seed value out of range"

• Explanation: The seed value provided is outside the acceptable range.
• Solution: Set the seed value between 0 and 4294967294.

"Creativity value out of range"

• Explanation: The creativity parameter is set outside the allowed range.
• Solution: Adjust the creativity value to be between 0.2 and 0.5.

"API key invalid"

• Explanation: The provided API key is not valid or has expired.
• Solution: Verify the API key and provide a valid one using the api_key_override parameter if necessary.
