有料のアップスケールソフトに匹敵する！日本発、無料のAIアップスケーラー、カクダイV1を使う方法

Alice from Zin Wonderland introduces the topic of upscaling images using AI, specifically focusing on the use of the Confui UI. She mentions the quality of upscaled workwear and suggests that viewers learn from her experience. She refers to a previous discussion about the upscaled image 'Maburisu,' which gained popularity for its beauty. Alice explains that AI is particularly good at upscaling and that the upscaled image in the demo seems to have strong elements of Stable Diffusion. She also mentions the 'Magical AI' upscaler, which is free to use, and the workflow for using the upscaler, which can be downloaded from the homepage. She notes that the upscaled image of meat looks very clear and that the image quality remains high even when upscaled. Alice also discusses the installation process for the 'ccsr' upscaler, which she had trouble installing, and suggests that viewers check if they can install it successfully. She provides a link to download the model for the 'ccsr' upscaler and mentions using a control net and a realistic model for upscaling realistic images.

Alice guides viewers through the process of using the nodes for image upscaling. She begins by loading an image and explains the use of the ChatGPT node to generate prompts, although she decides not to use it in this tutorial due to its complexity and potential cost. She then delves into the 'Magic Word' node, which allows for the adjustment of prompts within the node itself. Alice mentions the use of a 'Text Context Connect' node to concatenate text, which can be useful for encoding text into the image. She then describes the upscaling process using the 'ccsr' node, which upscales the image by default to four times its original size. She also discusses the use of a 'Basic Pipe' to combine various elements like checkpoints and text prompts. Alice explains that the 'Detail Denoise' node is used for a second pass to improve image quality, and she mentions the use of 'Tile Fusion' to make the image more natural. She also talks about the 'Self-Attention Guides' and 'Color Match' nodes, which help in refining the image and matching the color to the original. Alice concludes by showing the final upscaled image and mentions that she will create a video explaining how to build the nodes and use the Confui UI more effectively.

Alice concludes the video by reflecting on the upscaling process and the use of the 'Cyber Realistic' model, which she finds to be very effective for high-quality upscaling. She mentions that she has explored the 'Upscaling V1' workflow and will create a video to share her interpretation and practical application of the nodes. She plans to upload this video as a member-exclusive content and will consider discussing how to utilize the nodes effectively in that video. Alice thanks viewers for watching and invites them to join her next video, expressing her anticipation for their continued engagement.
