SDXL ComfyUI img2img - A simple workflow for image 2 image (img2img) with the SDXL diffusion model

In this quick episode we do a simple workflow where we upload an image into our SDXL graph inside of ComfyUI and add additional noise to produce an altered image. I show you how to drop it into a standard workflow as well as how to adjust it to get as much difference we we would like. This is a simple graph and can be used as a point of departure for your AI art or other stable diffusion projects. Note that I don't go overboard here with the noise, and you can really push this into another realm if you add noise over 50%, so feel free to experiment!

I just want to say something else that maybe others have missed regarding your excellent tutorials. It's not JUST that they're technically good, it's also because your voice is SO easy to listen to. You could teach all day and it wouldn't be exhausting for the student I think.

[@RufusTheRuse]

Thanks again for your video series here - I think it's very important for those picking up Comfy UI - it has helped me understand workflows I've loaded up off of the example workflow site. And I really appreciate it when you zoom into a node you're doing something interesting with - too far out and it becomes a compressed blur.

[@sedetweiler]

Glad it was helpful!

[@spiralofhope]

This worked great! Now I think I know enough to tie multiple previous tutorials together, to get several advantages. I don't know how to disable and reroute certain things easily, so it looks like I'll be maintaining multiple workflows.

[@royjones5790]

I would love a tutorial explaining how to create 2 independent prompts, run them together for composition. Method (1) : Using position & area numbers (such as, starting from X0-x300, y0-y200 for prompt 1, etc.) Method (2) :Allowing the mouse-drawn mask area to be fed with the prompt -- please include previews of the masks being done & a preview of the mask combination. I'd really appreciate it. ComfyUI allows for greater composition control & understanding how to do it will really lean into it's strength

[@spiralofhope]

omg I've been working for hours to try to figure out how to integrate this into the refinement workflow from earlier in the playlist.

[@sedetweiler]

Did you get it? Just checking that you are all good now.

[@spiralofhope]

@@sedetweiler Edit: I think I figured it out! I had things in the wrong order and some values were a bit wonky. 5 img2img steps, denoised to 0.80 -> 3 refiner initialization -> 20 base sampling steps -> 12 final refining steps (not sure about this one) -- I don't think so. I started with the refiner workflow, ending with a final image. This is an exact copy of a previous tutorial and it works 100% At the end of that workflow is a KSampler. I take that and split it off its latent. I take that latent and pass it through an image scale to side, with the side length of the longest of height or width I've been working with. I pass that latent to a LatentAdd and bring it into an exact copy of the img2img tutorial. I take that LatentAdd and insert it just before the img2img KSampler. It.. "does stuff" but I intuit it isn't correct. I already cleaned it up with groups (which was new to me), and I'm working on cleaning it up with reroutes so I can show it. I don't like that reroutes are someone else's extension because it feels like something that can break on updates, but I hope that reroutes are popular enough to demand updates.

Great video! Can you share the json file for this work flow?

[@jjgravelle]

It was nice spending the weekend with you, boss. Well, with your videos, anyway. You've got me psyched on ComfyUI. Two things I hope to see you cover, eventually: 1.) You mentioned in another video that ComfyUI might be used for model training? Yes, please; and 2.) RE: the .yaml tweak for sharing a model folder touches on a larger issue. Play around with AI for a few days, and you end up with Oobabooga, TavernAI, Docker, Jupyter, the WSL, half a terrabyte's worth of LLMS, et al AND competing versions of Python (for X you need 3.10, for Y you need 3.11)... then there are the Condas and Cudas and-- you get the picture. As methodical and organized as you are, I'm guessing your hard drive is set up logically and efficiently. A peek into the nuts and bolts of your setup would be, as the kids say, amaze-balls... Your pal, -jjg

Awesome to hear buddy! 🥂

[@digiovannidesign910]

Scott: I am really enjoying your videos. You mention in your videos if we have a question to drop it in the comments. I have a more general question about Stable Diffusion, ComfyUI, Automatic111, and MidJourney. Is it best to post here or somewhere else?

I have the latest Derfuu nodes but I only have Width or Height Options on "Image scale to side" and not "Longest". any ideas why?

[@sedetweiler]

I would just do a pull off the latest. Might be a new addition.

[@MaisnerProductions]

How is it that all your width and height inputs say 1024, yet your output image appears to be a portrait aspect ratio?

[@joneschunghk]

Would a "base" or "refiner" model be better for img2img?

[@user-fu5sz4su8u]

I wonder whether there is workflow for i2i in batch because I want create video.

[@marklouisehargreaves]

In ComfyUI is it possible to change the folder the saved images go to?

[@lioncrud9096]

is there a way to do higher batch number than 1 at a time....i use an Efficient Loader that combines Model, Prompts, VAE, and Batch Steps in one node. When i increase the batch number to say,3, Comfy only does 1 image.

[@sedetweiler]

Perhaps the batch number is being bugged when part of the group? That is how I would normally do more than one per batch.

[@jpgamestudio]

Hello brother, what is the function of the "clip space" on the menu on the right?

[@thecolonelpridereview]

Nice tutorial. What's the advantage or difference in using Primitive plus CLIPTextEncodeSDXL compared to using CLIPTextEncode(PROMPT) for your prompts?

[@sedetweiler]

You can use both of the CLIP models if you use the SDXL one, otherwise you are only using one.

[@BlackDim100]

I guess you can also use the scaler to upscale the final image output?

[@sedetweiler]

I put out a video today on that, since you can do that, but there are much better ways to get great results.

[@roseydeep4896]

idk if it's a stupid question to ask but I'm a newbie soooo.... Why does the SDXL CLIP encoder node have two text inputs? At first I thought it would be for both the positive and negative prompts but apparently it isn't. I don't get why you need to connect the primitive node twice lol.

[@sedetweiler]

There are 2 different CLIP models you can leverage. I will go into this deeper in another video but for now, they are both either positive or negative.

[@n3bie]

When I followed this tutorial , after I created the primitive node and was going to connect it to the CLIPTextEncodeSDXL node as you did @0:54 I had a Text_I linker, but not the one for the text_g linker. As you do in this video. What am I doing wrong? I'm building this workflow underneath (and disconnected from) the default workflow. Could that be causing it?

[@anujpartihar]

Sir is it possible to use this sdxl online? like without using the GPU since my laptop is not very powerful but I would love to dive into this stuff. I am very new to all this so forgive me for asking the obvious.

[@dr.gurn420]

how do you make your projects run and compile so quickly?? I tried using a VM on run diffusion and it still takes 2-5 minutes. Do you have any other VMs you would recommend that are affordable? thank you for the content

[@user-bu8jc1eb1z]

Hi, thanks or the video, I wanna add control net into this node, use img to img to do some line art animate style but with is it possible? I tried to combine the node that you share about controlnet, but not success, thank you.

[@KallutoZoldyck]

This helps with text to video, but how do I do image to video locally? Text to video is kind of useless with LoRA involvement if we actually want good results

And refresh browser." But when I clikc on the RESTART button, it show only RECONNECTING... that lasts foerver.

I don't understand this compulsion to speak and point and click so rapidly. Not everyone is as familiar with this system as you are.

You speak and click WAY too fast. And I'm a native English speaker with six months experience with Stable Diffusion on another UI. Subtitles aren't available here for some reason. In other words, follow the basic tenet of teaching: 1) tell them what you're going to tell them, 2) tell them, 3) tell them what you told them. It works. I taught hi tech subjects to adults for years. Then, the tutorials will be of lasting benefit to everyone, rather than an exercise in noob frustration.
