Upscale and Enhance with ADDED DETAIL to 4K + (Better than Topaz)
TLDRIn this informative video, Matt guides viewers on how to upscale low-resolution images to 4K using a stable diffusion model. He explains the process step-by-step, emphasizing the importance of using specific settings such as DPM Plus+ 2m SD, exponential sampling steps, and denoising levels. Matt also discusses the use of control nets and scripts, particularly the 'ultimate SD upscale script,' to achieve enhanced detail and realism in the final image. His expertise as an archviz artist is highlighted, and he invites viewers to explore his website for more tutorials and resources on generative imagery and architecture visualization.
Takeaways
- 🎨 Use a 1.5 stable diffusion model for image upscaling.
- 🖼️ Start on the 'image to image' tab with simple prompts: 'photo', 'fine detail', and 'real' without negative prompts.
- 📐 Ensure the low-resolution image's dimensions are under 2K for this process.
- 🧪 Apply the sampling method DPM Plus+ 2m SD with exponential sampling steps set to 40.
- 🔇 Set denoising to 0.55 and experiment with values between 0 and 0.65.
- 🛠️ Enable control net with 'tile' and 'Pixel Perfect' checked for better image processing.
- 📜 Load the 'ultimate SD upscale' script from the extensions for additional enhancement.
- 🏞️ Choose a model like Valor for nature scenes or use the 4X ultra-sharp model as an alternative.
- 🔢 Set the upscale value to 4, tile width to 1024, mask blur to 64 pixels, and padding to 128 for seamless image blocks.
- 🔄 The upscaling process involves overlapping 1K blocks to avoid visible seams and composite the final image.

Q & A
What is the main topic of the video?
-The main topic of the video is about setting up a stable diffusion model to upscale low resolution images to 4K while adding new and detailed content.
Which stable diffusion model does the speaker use at the beginning of the video?
-The speaker uses the 1.5 stable diffusion model, specifically mentioning the use of Epic Photog, Gasm Zed Universal.
What are the key settings for the image to image tab?
-The key settings for the image to image tab include prompts like 'photo fine detail' and 'real', with no negative prompts, and ensuring the width and height of the low resolution image is under 2K.
What sampling method and parameters does the speaker recommend for upscaling?
-The speaker recommends using the DPM Plus+ 2m SD method with exponential sampling steps set to 40, CFG scales at 4, and denoising at 0.55.
How does the speaker suggest using the control net in the process?
-The speaker suggests enabling the control net and using 'tile' along with 'Pixel Perfect'. The model should be loaded within the control net directory.
What script does the speaker typically use for upscaling?
-The speaker typically uses the 'ultimate SD upscale script' which can be found in the extensions by searching for 'ultimate'.
What model does the speaker use for the nature example in the video?
-For the nature example, the speaker uses the Valor model.
What is the purpose of the padding setting in the process?
-The padding setting, set to 128, is used to create an overlap, preventing noticeable seams in the final upscaled image.
How does the speaker's website, Hallet Visual, relate to the content of the video?
-Hallet Visual is the speaker's website where he shares his expertise as an archviz artist and provides tutorials on generative imagery and architecture visualization workflows, including character development, texture creation, and render elements.
What is the final result of the upscaling process demonstrated in the video?
-The final result is an upscaled 4K image from a 1K original, with added details such as moss on trees and pot lights, achieved through the use of the upscaler and the described settings.
What additional resources does the speaker promise to provide for those interested in learning more?
-The speaker promises to provide a full set of lessons, covering various techniques including image enhancement and upscaling, through his website and future video content.
