@21:29 Slight oversight. Connect the Width and the Height to the downscale from the Image Resize at the bottom (divisible by 32 group) and NOT THE ORIGINAL. Thanks to the user "dr.gurn420" for correctly catching this oversight. The oversight would affect only if Downscaling an non 32 divisible image. Would have no effect if using the rinse and repeat (upscale downscale method) as shown in the video.

[@KQforever]

Do you mean from the "Divisible by 64" group? I'm reading what you wrote here as exactly what is already happening in the video.

[@KQforever]

Additionally, are you supposed to connect the image output from the image crop in the "divisible by 64" group and apply that to the image resize image input in the "upscale factor" group? or are you supposed to use the original image as seen in the video? I dont understand why you wouldn't always use the cropped image especially if your upscale factor group is already changing the size to the cropped image heights & widths

[@controlaltai]

Please Check the video further. All output from the image resize is connected to the switch which passes on to the upscale. If you are doing directly connect from the bottom group to upscale factor.

[@controlaltai]

@@KQforever Yes divisible by 64 group (as per that section of the video), When making the video it I was still testing it was 64, then in between I had to switch to 32, finally went with 32. if it works with 32, it will work with 64.

What AI voice do you use?

[@dr.gurn420]

hey - great video!

[@controlaltai]

Hey, Thanks! Okay, you got the oversight accurately. Let me explain what I was thinking when I did that. If the image is divisible by 32, the crop will not do anything. If not, it will crop the image to the nearest number, which is divisible by 32. For the downscale, you are correct. The image resolution is from the original, but the image source is from the cropped. The correct way would be to connect the cropped width and height to the downscale input instead from the original. Why it doesn't matter. Because if you have a high res image, we are not going to use SUPIR for restoration. The image is already high res and proper. The downscale method here is a rinse-and-repeat method, meaning you take a low-res image and correct it by making it divisible by 32, which is done during upscale, we then use that to downscale, upscale again (rinse and repeat). The divisibility by 32 is fixed during the first upscale pass. Therefor calculation will always be correct in the downscale in the second and subsequent passes, whether width and height are coming from the crop output or the new original. This is an oversight from my side, as the downscale was never meant to be used for directly inputting a 4 K image, for example, and downscaling to upscale. It was meant for low-res, to upscale through multiple passes. The first pass would correct the divisibility by 32. So, you are the first person to get this oversight correctly. To answer your query, the 100% correct way would be to take the width and height values of the downscale from the cropped output. I got the oversight; however, I did not correct it since I only use the downscale for the rinse and repeat, so the res is always divisible by 32, no matter if it is coming from the original or crop output. (by image crop output I mean, the width and height from the image resize node in the bottom group) I have pinned a message mentioning the correction for the oversight.

@@controlaltaiI see. How does your workflow differ from other Supir workflows available? do they have the divisible by 8 and 32 nodes etc that you have? ar they dynamic like yours?

[@controlaltai]

@gohan2091 You can check out the SUPIR workflow by Dev himself, who implemented this, you will get it under custom node, SUPIR, examples folder. The SUPIR upscale group in the video that’s what the basic workflow consist off, everything else is additional and done by me. Also the settings used for the sampler are very different. The workflow will give consistent accurate results, with these settings. The only limiting factor I see is the hardware. If I had better hardware I would just use full tiling for every image and be done with it. The workflow has dynamic automation for practical use. For example, you don’t want to calculate every image manually, different tile setting is a unique approach, ability to switch things on the fly and so on….I cannot speak about other SUPIR workflows. I have only seen the default given by the dev. Edit: divisibility by 8 is taken care of by comfy, not 32. The issue comes to convert to 8/32 both. You can always manually convert crop outside comfy. Images generated using Stable diffusion won't have any compatibility issues.

[@gohan2091]

@@controlaltaiWe appear to have the same hardware. It's the best we can get at the moment (without spending tens of thousands) I must admit, I am not fully understand the 3 different modes but I will re-watch your video later. I am using the dev workflow now, cannot even figure out how to increase the size but it's definitely improving quality. I am having to guess settings though like s_chum, s_noise, DPMPP eta etc. I guess with your workflow, I would still have to guess the settings?

[@controlaltai]

@@gohan2091 I do explain the settings in detail, it’s complicated. If you want consistent, high accuracy result, try with the settings I used, changes in the setting mostly result in creative output, which personally, should be avoided for upscaling. But yeah, for example if you want some color change or add more details etc, you have play around with it. The tiles matter, in terms of vram usage. Typically close to original, will always give best quality, but above 2k it’s very difficult on 24gb vram. Secondly, on that setting it takes more time, if doing in batches, then maybe a middle ground would be a good balance on speed and quality. It just good to have flexibility in the workflow.

This was a lot like this mathclass meme, starts out simple, get distracted for a second and suddely the whole board is full, luckily this is a video, pause rewind and replay. Phew that was a lot. What if your old images are discolored or faded? Like an old polaroid that turned very red over the years

[@controlaltai]

For old images discoloration it's a bit more complicated. The first thing is to get it to restore to some degree, 1k. Then you have to use another workflow probably the ControlNet re color one. kzbin.info/www/bejne/noW2pWOveL5gpacsi=bF4qIFUg3K7lnMrk The simplest trick would be to make the image black and white and then add color again. Finally use SUPIR again to upscale for 2k or higher. For cracks and other stuff you can use Fooocus inpainting as shown here... kzbin.info/www/bejne/rXbHYqqGoah1l7Msi=yQJibUveCYe_oaFl

Other solutions are complicated to explain in a comment. You have to do a whole math conversion set of nodes that check divisibility of 32 then send the image width and height to inputs of the image resize. I still think you are using the wrong image resize node. There are several. Enable tags to confirm which image resize node are you using in comfy.

[@user-rk3wy7bz8h]

@@controlaltaiSorry, whats the meaning of : enable tags to confirm. I didn't understand how to enable tags, whats that. By the way i have other question. I did exactly the same workflow with the same reference image and seed and all things. Except the fp-8 unet , i have it on false becauss i have only 8000vram and 32 Gg system Ram. Now the question is that i get other output than you got. The face is someone else, its not bad but its different than yours. Is it normal if this happens?

[@controlaltai]

Go to settings and enable badges, this way you can see what custom node does the node belong to. It will show the custom node name on the to right. Okay so, about the different face, that's normal. This is because the image I used has a massive data loss, generative ai is what the name says it is. With every seed you may get a different face. Also using fp8 means less precission. The adding of new data won't be the same as fp 16 or fp32. People normally mis understand the word restore and think the ai would know exactly what the face looked like. Thats un true cause the AI sees what you see just bit more, the word restore comes since it maintains the structure of everything else, like it gets that there is an emblem of sort on the top of the hat, there is a strap for the hat, etc. So its completely normal to get a different face for such a massively lost image.

[@andrewq7125]

It might be better to do an upscale or downscale image the first, and then resize the image to a multiple of 32?

[@controlaltai]

The multiple of 32 applies only if it's not a multiple of 32. Technically it's doesn't matter. You would want the image to be as close to the original as possible. There is no image upscaling before conversion otherwise supir gives error. Downscale is case to case bases. Once the image is a multiple of 32. The entire multiple of 32 process is ignore and nothing in terms of resolution happens to the image.

[@DeadDude4]

I agree with you @andrewq7125 . This workflow makes the assumption that you don't start with a downscale. So as long as you start with an upscale it works fine. I have a partially blurry image I wanted to try this workflow on with a size of 3168 (w) by 4752 (h). The workflow cropped the image down to 3168 by 3168 but then when downscaled 4x it becomes 792 by 792 which cannot be divided by 32. If I changed the crop factor to being divisible by 128 instead of 32 it worked fine. It just doesn't make sense to have to manually calculate those things in advance considering how automated this workflow is, so best to change the workflow to start with the downscale at the very least, bypass it if not downscaling and then crop and upscale. That being said, it's a good tutorial though. As a beginner there's alot I've learned from this tutorial

[@controlaltai]

Hi, I saw the oversight some days back, as pointed out by another user, and provided a solution in a pinned comment. If you start downscaling from the beginning, you just have to make one change. "@21:29 Slight oversight. Connect the Width and the Height to the downscale from the Image Resize at the bottom (divisible by 32 group) and NOT THE ORIGINAL. Thanks to the user "dr.gurn420" for correctly catching this oversight. The oversight would affect only if Downscaling an non 32 divisible image.

It's too much info at the middle. You lost me when you doing the upscale, downscale, and setup the swiches and such.

Well, watch the video right at till the end where the techniques used especially the cases where downscale upscale and downscale are used repeatedly to upscale a single photo. These switches were not added for personal preference only. To show some of the supir techniques you require them. You can however skip just go to the next section. Don't add the switch only the 2x upscale. Connect the height and width from the bottom to the upscale factor input. Wherever the switch connects to.

those images to start with of the policeman were awful. If you're going to grab attention you need to start with something good. I doubt that policeman actually looked anything like that final image.

The thing is... People request these kinda things.. Often another family member or such will tell you how close it is.. It could be way off it could be pretty close... No way to tell really..

​@@supernielsen1223 That's exactly why it was a terrible showcase. I am interested in a process to restore some detail, not to completely reimagine a photo. After seeing that horrible example at the start, I stopped watching this video. Waste of time.

@@supernielsen1223 It's very easy to tell with the policeman, lol. The original image is of a dorky, bewildered English-looking guy. The after image is of a less bewildered, somewhat middle-eastern man. It's not just hallucinating new detail; it actually completely changed the obvious remaining detail from the original image.

Am I correct in understanding that this workflow does not use the juggernaut model? I saw different tutorials and they used juggernaut sdxl model everywhere

Yes, it uses RealVis_XL version 4 (baked vae), normal one.

Switch to default tile, use custom resolution, don't upscale 2x. Check original image size. If higher than 1024 then downscale to 1024. One of the above issues, low vram/system ram
