im getting low opacity faces on some tiles of the image how to fix it

[@AscendantStoic]

Few things:- 1-10:22 If you want an upscaler that adds details to skins try 4x_NMKD-Siax_200k or 4x_NickelbackFS_72000_G, when I upscaled using those two the person's skin went from plastic smooth to highly realistic (with blemishes, veins, wrinkles, pores, beauty marks...seems these upscalers were trained on photos specifically). 2-5:00 When I use the Seams Fix option in Ultimate Upscale I get 2 results, one of them before the seams fix and one of them after, and the one "after" barely has any noticeable seams whatsoever, so maybe try checking the "seams fix" option, either way it's still miles ahead of the original SD Upscale which suffered from ghosting issues between squares.

You're welcome! Thank you for the support you've given Ronny, it means a lot to me.

[@Jukahetube]

I think the different results between stepped upscale and direct upscale are quite easy to explain. With the direct to 8k method each 'starting tile' is quite blurry so the controlnet has trouble doing it's job of making the added detail make sense within the context of the image. In comparison the downside of stepped upscaling seems to be general loss of detail at each pass which has a cumulative effect. I think both of these downsides can be mitigated and there is probably a sweet spot to be found for number of stages to maintain both coherence and detail. Some general rule like "fewer stages is better as long as each tile is sharp enough for controlnet to work" might apply. Or; "Two stages are good, three is ok, four will loose too much detail". Finally, if there are techniques that can be used to mitigate the loss of detail on the staged approach it might be superior overall.

[@parsley8188]

Oh this is a godsend. I work on a children-book with a lot of photorealistic images in the moment and use a combined approach of oldschool Photoshop work and Stable Diffusion and struggle a bit with the upscaling in some images. I‘ll spend the rest of the night using this approach and think that it will solve my issues. Thanks for the great video!

[@mrzackcole]

I'm a composite artist doing the same kind of work. Would love to follow your journey! Are you sharing your work anywhere?

[@theresalwaysanotherway3996]

quick tip for speed: you can turn up the tile width to generate the upscale faster, as it requires less total tiles and so the total time waiting between each tile is reduced. It also allows controlnet when upscaling to retain more context from the image, theoretically resulting in a better picture. 768x768 is the obvious option to choose, but even higher is an option.

[@sebastiankamph]

I had a think about this. For the 768 models, surely. But the ones trained on 512, I assume the image quality running 512 must be better compared to the speed gains? Either way, interesting thought.

[@Steamrick]

@@sebastiankamph I've always found that even 512 models do find with higher resolutions once they have a framework to work with.

[@edwardchyrek]

Nobody can mastrubate that quickly!

[@morphles]

@@sebastiankamph The 512 models being limited to 512 is sorta legend at this point imo. Some of comunity models can do ~1024x800 very decently. crystalClearV1 (note v1, v2 seems to have screwed up) is very nice model for that. I'm pretty sure you can gen 768x768 with it with no problems. Though there is usual caveat that aspect ration is very important depending on prompt.

[@fixelheimer3726]

I've tried with 512,768,1024 and 2048.you get less mutations and stuff with higher tile size,if you also lose quality or depth, I'm unsure. One thing for sure going 2x in upscale multiple times is better than 4x for example in a single step regarding end quality

[@Herman_HMS]

Smoothing also comes from low number of steps. As denoise strentgh is lowering them, set them at least 100+, then steps on each tile will be 10+ with denoising around 0.1. It will provide more details and texture to images.

[@76abbath]

Thanks a lot Sebastian! Your explanations are very useful! ❤

[@sebastiankamph]

😘😘

[@sidewaysdesign]

Regarding stepping up vs. max in one step, the images are so close to one another that you could stack the output in an app like Photoshop and paint in a mask that would blend the best aspects of each. Similarly, the background tiling example you showed could easily be masked over with a dedicated AI upscaler like Topaz.

[@bryan98pa]

But with A1111 you can add/fix some details while you upscale a photo

[@filmyk]

6:34 To improve this we could use a photography technique, we could add noise to the image. In addition we could mask the noise according to the luminance of the photo, so that the noise is more pronounced in the dark elements of the image and less in the light ones, to affect the portrait as little as possible and as much as possible to the background. It is a common technique to remove banding from images.

[@RSKT_music]

I think you could use both of the results at the end. Use frequency separation in Photoshop and ad it to your 4k render. Erase the parts that don't work :)

[@alecubudulecu]

I like using the tule diffusion extensión instead. Same thing. Just I find it gives more granular control over the upscale. You can do quadrant prompting to target specific sections. And you can change the denoise or CFG just for the tiles or have heightxwidth custom settings for each tile

[@sebastiankamph]

Thank you for the comment, glad the video was helpful!

[@robertpaulson4960]

This is getting so amazing. When I get a txt2image that's good, I will use it to gen a few images at 4k res with a .3 denoising. I then take them into photoshop as layers and erase all the bad parts until I have the best image. Then I take that image and upscale it to 8k. I resize that back down to 4k bring it back into photoshop and erase any bad detail it may have picked up. Then I set denoising to .15 or .2 and upscale to 8k. edit: I should mention if the txt2image you have has any imperfections they will be amplified, use inpainting to fix them first.

[@Philson]

THANK YOU SO MUCH FOR THIS!

[@FirstLast-pu9ty]

You could also do a regular quick upscale and then send the scaled image back to in-paint and then mask an area where the detail was lost and regenerate that area using a new prompt that covers only that masked area. And then repeat for other areas. A blurry area like an out of focus background is not going to need any extra detail anyway. Only add detail where it's needed.

[@ulamss5]

5:15 thank you for that detailed look into seams. It's been driving me crazy. Someone who opened an issue mentioned that apparently it goes away in Linux, but I can't verify that.

[@coda514]

Great content Seb. Informative as always, you help "demystify" all of these extensions for the common man. BTW, Did you see the display of still-life art? It was not at all moving.

[@sebastiankamph]

Thanks! 😂💯

[@hermitcleric]

Firstly thanks a lot for the video, it was my starting point. So, I experimented a lot with this and found out that the reason you might be getting less detail and smoothed out skin is that while you're setting low denoise 0.15, and therefore very low freedom to create content, you're using sampler Euler a, which generates a lot of chaos. What I'm doing is setting denoise to 0.4, sampler DPM++ 2M Karras, but to compensate for the extra freedom I'm giving to the machine I crank up ControlNet's "Control Weight" to 2. I've achieved great results. You can also experiment with the CFG scale between 7 (default) and 14 if you want to force the machine to create certain details. Oh yeah, and DEFINITELY use Deliberate or Reliberate guys. These checkpoints are game-changing.

[@Alukardo11]

This is all was i asking for, similar to the Midjourney Upscaler in their Web. Many Thanks Sir

[@hasuwini]

That was amazing my dude! Would love to have a continuation video with the same thing but working on a small video, like how to use controlnet in that manner with potato PC doing a small animation if possible upscaled... Let me know if that could be a thing!

[@orirune3079]

One trick I recently discovered and started to experiment with is to generate two images, one with low denoising (0.15-0.25) and one with higher denoising (0.5-0.6). Then I load them both into Gimp, with the low denoised image above the high denoised one (so the less-changed image is on top). Then apply a transparent mask, and cycle between the images, and paint it over any parts where you think the low-denoised image needs more detail. This allows you to keep any good detail generated by the higher denoising, while having the majority of the image not overly changed. Of course, it takes a lot of time and effort, but I think it's worth it.

You can also use multidiffusion, it does basically the same thing automatically, and it actually ADDS detail instead of removing it.

[@trsd8640]

@sebastian : Pls add Upscaling tutorial with Multidiffusion! The results seem to be better than with tiles. But my mac gets ot of memory on higher resolutions

[@manleycreations6466]

To combat the over smoothing of details, you could bring it into Photoshop and use an unsharp mask to add detail, then send that back to SD to upscale.

[@sebastiankamph]

I love unsharp mask! Good tip. I usually use it for final touches.

[@Skittlz444]

That "smoothing" you're getting is actually the upscaler, 4x-Ultrasharp is actually not perfect at retaining details as you showed, it's very good, very efficient, and fast (being a GAN). I personally like LDSR for keeping details, it's slower by far and more memory intensive yes, but there is much less smoothing. Haven't tried with tiling and your work flow to try and scale to insane sizes, worth you trying out though

[@lyonstyle]

fantastic video sebastian! everyone is sleeping on controlnet, it has tons of possibilities

[@LordQuackyy]

Fantastic work, love learning from your videos as well as the great advancements from AI digital design and everything which is possible! I've not seen anywhere and unable to locate this anywhere currently. But are you aware of any AI or any suitable method from turning a 2d design to a 3d game ready asset without using blender? I'm happy if the result isn't perfect and requires some minor adjustments, but currently looking for a method to effectively reduce the time taken within blender.

[@sinanisler1]

nice thanks my dude

[@CleomokaAIArt]

Hi Sebastian love your videos and thanks for this one! So I experimented with this method, and compared to other AI upscaling options, and I must say Gigapixel AI is a significantly better option for upscaling especially its most recent version in speed, details and ease of use. I havent yet found a great upscaling method within automatic1111 / SD to get to 4k or above resolution (I do use hi res fix), that comes close to a commercial solution. Either way great video, I was just disappointed this didnt turn out to be the holy grail. Maybe soon in the future!

[@neonskimmer]

Thank you for all your helpful videos! I noticed you are using Deliberate V2 in here, my current favorite. I'm upscaling a batch of images for a project and I've been using the _Inpainting_ version of Deliberate V2. Do you know if it makes a difference? I will do my own tests but intuitively I feel it might be more suitable but i'm an absolute newbie so I might be completely wrong here :)

[@stibo]

I've noticed that if you use the 4x Ultrasharp model, it changes the color of the result slightly. I think the 4x_UniversalUpscalerV2-Sharper_103000_G gives a more accurate colored result.

I did a lot of test the last 4 days, working the same way as you (but updating the ControlNet reference image every time) and I found that the detail gain is really depending on the models but also of the prompt. Some models are slowly loosing details when some other are gaining amazing things...

[@mikerhinos]

I'm using the ultimate SD upscale technique for quite a while now and didn't really saw an advantage using ControlNet (yet), but when I go into the upscale steps, I delete the prompts and only keep the quality keywords, like "ultra detailed, 8K, hasselblad" and denoise at 0.15 to max 0.30, and put back random seed, so nothing will influence the details creation. Every tile is passed through the algorithm separately, that's why if you keep a high denoise it will generate a collage of different images, so random noise, low denoise :) Try it and let me know ;)

[@mikerhinos]

After viewing the video from Olivio Sarikas (kzbin.info/www/bejne/aauXfn6Lpqt4i80) I made multiple tests with the tile ControlNet, and it helps getting a better image quality upscaling directly to x4.

Oh, say, I had an idea for use with ControlNet... I don't have a channel, so I thought I'd share it with you in case you might like to make a video about it. The easiest way to create custom poses for use with ControlNet is to use one of those artist's manikins. It seems so obvious to me in hindsight that I feel kinda dumb for not thinking of it sooner. You can create any pose you want, and then easily get any specific angle of perspective on it once you have your pose, a lot easier than posing yourself and taking a picture, because controlling the framing and angle are going to be so much easier this way, plus easier to set up a green/white screen to have no background, etc.

[@mamadsc]

About the loss of details between the 2048 and 4096, I have two comments after doing some experiments : 1.Shouldn't you feed back the resulting image to ControlNet image after each pass (or just removing the image from ControlNet, it will automatically select the image being img2img) ? Because in your example the 4096 image is being built from the control of a 512px, I guess it makes sense that it would lose a lot of details. 2.I'd try to add more Denoising strength. 0.15 seems low for the amount of new pixels being created between 2048=>4096. Without letting the model denoise more, I think it has to look more "smooth" due to the basic resizing and expansion of pixels. Anyway, great video thanks :)

[@Steamrick]

Have you tried iterating the control net? I mean, always inputting the img2img output into the control net for the next stage? Also, I'd try putting something regarding old skin into the prompt. You know, 'age spots', 'wrinkles', stuff like that. That should help, especially if you go for a bit higher denoise.
