Stable Cascade in ComfyUI with Updated Method and Custom Workflows

The video begins with an introduction to an updated method for using Sable and Cascade in Comfort UI. The host plans to guide the audience through workflows provided by Comfy Anonymous from the comfi repository and share custom workflows. The first step involves ensuring readiness to use the updated method by downloading checkpoints specifically made for Comfy UI from the stable Cascade examples page in the Comfy UI repo. The video then explains the process of storing these checkpoints in the appropriate folder, depending on the user's setup, and emphasizes the need to update Comfy UI to ensure compatibility with the new workflows. The host also provides a brief overview of the text-to-image workflow, highlighting the sequence of models used and the creation of a text encoding fed into a sampler.

This paragraph delves into the text-to-image workflow using the stable Cascade method. The host demonstrates how to run the workflow using the default prompt, which describes an evening sunset scenery. The process involves loading the checkpoints, generating the stage C, and progressing through Stage B to obtain the final image. The video showcases the results of the text-to-image workflow, explaining the role of the stable Cascade checkpoints in creating the image using the Comfy UI platform. The host also touches on the image-to-image workflow, which was not covered in previous videos, and contrasts it with the text-to-image process.

The host introduces two methods to enhance the output of the stable Cascade models, addressing issues with noisier textures and an overbaked look. The first method is a high-resolution fix, which involves a two-pass stable Cascade process. The video explains the process of upscaling the image and converting it back into latents for further refinement. The second method involves using an XD XL model to achieve a specific aesthetic. The host shares a workflow that combines the strengths of stable Cascade and XD XL, ensuring the composition remains true to the original while improving the visual quality. The video provides a detailed walkthrough of each step, including the installation of custom nodes and the use of specific models and checkpoints.

The paragraph discusses an advanced workflow involving a triple pass of the stable Cascade process with upscaling in the latter two passes. The host outlines the process of manually setting resolutions for each pass to generate high-quality widescreen wallpapers. The video highlights the importance of maintaining the same aspect ratio throughout the passes and adjusting the compression value for better detail. The host demonstrates the workflow using a digital painting example, showing the improvements in detail and noise reduction at each stage. The video emphasizes the need to experiment with the denoising value to balance composition and detail, and concludes with a comparison of the initial and final outputs.

In the concluding paragraph, the host recaps the video's content, highlighting the preference for the highres fix stable Cascade workflow over the stable Cascade to XD XL model for most use cases. The video demonstrates the final result of the triple pass workflow, showcasing a detailed and clean image suitable for wallpapers. The host mentions plans to upscale the final image using a tool like Topaz, suggesting alternative methods for viewers. The video ends with a prompt for viewers to explore the workflows and find the one that best suits their needs, and signs off with a musical note, indicating the video's end.
