00:00[Music] Hello, my friends, how are you doing today? I want to take you on a journey that is probably going to change your life

00:08We're going to have a lot of fun with ComfyUI, and I'm going to show you why it is so capable and such an amazing tool

00:16I want you to imagine ComfyUI as a canvas on which you doodle

00:23Imagine yourself as a kid, and you just draw out anything that is in your mind, in your fantasy, because ComfyUI is absolutely adaptable and open

00:36So, in this video, in this lesson, we're going to talk about the basic functionality and how to understand it and create in an easy and fun way

00:43Here we have a very simple workflow

00:46That is just creating this very nice image here

00:51You can see here there's different elements in here, and we have here these lines that are connecting everything together, so we're going to build that together

00:59But before we do that, I'm going to show you how the interface itself works, so let's start fresh here with this element

01:07You can move that around any way you want it on the screen

01:09Here you have several controls in there, and there might be something you don't have

01:16This is the manager, and that is very important because here you can install all of the custom noes, which are these little boxes we have just seen

01:23Now, this is very, very easy to install

01:26You need to go to the GitHub page of the Comfy Manager, and then you want to scroll down a little bit, and here you see this text line: "git clone," and then the web address of the Comfy Manager

01:40You want to select all of that and copy that

01:42Then you're going to go into your ComfyUI Windows portable folder, in there, in the ComfyUI folder, in there, into the custom nodes folder, and when you're here, you want to click up here in the address bar and type "CMD" and hit enter

01:59This is going to open up your command window, and here you'll simply paste what you copied before

02:07Now that the text is in here, you Simply hit enter and wait for it to finish downloading, should only take a couple of seconds

02:13After you've done that, you can close the command window, and you're going to click here in the ComfyUI Windows portable folder again on run Nvidia, cu bat

02:23This is going to start ComfyUI for you, and it's finishing the installation of the manager

02:29Once you have that, and you see this button here, click on that, and you will see this

02:36There's a lot of different buttons in here, but they are all easy to understand

02:40There are three buttons that are very important for you, one is the update all button, and over here you might get a message

02:47That your ComfyUI is outdated, so you can click on that and wait for it to finish

02:52This will update ComfyUI and all of the custom nodes that you have installed

02:57The second one that is very important for you is the "Install Custom Nodes" button

03:02Here, you can click on that, and this is going to open up a list for you

03:07You can see on the right side when you already have installed nodes

03:09You can either disable them or uninstall them

03:14Disabling might be useful when they are conflicting with other custom nodes, and of course, you also have an install button, so you can go and install it from here

03:23You don't even have to go to the GitHub page anymore

03:25Now here are some of the note packs that I want to suggest to you

03:31One is called the Comfy Impact Pack, the other one, Comfy Inspire Pack, the efficiency notes for Comfy, the ultimate SD upscale, and then also the Comfyroll Custom Nodes, because these have some of the most used custom nodes in them

03:51Another thing you might want to do in here is to install models

03:53When you click on that, you will have here a list of models

03:58Now, you will realize that these are often not models that you are using for image generation itself, for example, up here

04:06This one, for example, is very good, the 4x Full Hearty Remacri

04:08The 4X Ultra sharp is also very good, the 8X N MKD super scale 150,000g is also very good, and you can actually see on the left side by the type what it is

04:24You see here we have app scale inside face face rest, or we have checkpoints, we have embeddings, and so on

04:32Don't be too much concerned about that right now, we don't need all of that at this moment

04:37Before we get started, you might want to do one more thing

04:39You will find the file extra model paths yamama example

04:45Now you want to delete the dot example part at the end, so it's becoming a YAML file, and then you can open this up

04:53Personally, I'm using for that the Notepad++ software

04:55But you can use any kind of text editor if you want to

04:58Now, if you already have, for example, Automatic 1111 installed, what you want to do is to set the base path to your Automatic 1111, and in there to the web UI folder, and then this will automatically link to these other folders here with the same structure

05:17So that means it loads all of the models that you have from Automatic 1111 without having them as a duplicate on your hard drive

05:27You want to save that, and you can close all of that, and then you can click in the menu here on refresh, so it's loading all of the models, or alternatively, you can simply restart Comfy

05:39If you want to make sure that everything is loading correctly, now where do we find the notes, and where do we create that? Here is one advice I want to give you: you can zoom in and out with your mouse wheel, and when you do so, you will realize there's a very thin blue line around here

05:58Here now, this is the starting area of your canvas, so when you start to build, make sure that everything is inside of that blue line

06:06You can go over the blue line, but the core of your workflow should be inside of that blue rectangle here, because next time you load your workflow, it's loading that area of the workflow

06:18Next, of course, we want to Add some nodes in here

06:21The easiest way to do this is to double click on the canvas

06:25This is going to give you this search window here

06:27You can see you can scroll through all of the notes, but even better, you can type up here what you want to have, for example, K sampler

06:36This is for creating the images

06:40Now we want to click on that, and you can see this is adding the note for us, so this is super simple, and of course, you need to know the name of the note, but over time, because you in most cases use the same notes, you will remember the names over time, or you can look them up in other workflows or ask in the Discord communities for

06:59ComfyUI, so in here you see we have some inputs here for the model, positive prompt, negative prompt, the latent image, which is the latent noise or anything you want to input as a latent image, and then we have some settings here, like the seed number you want to have here, maybe randomizing the seed, but you can also choose here from these pop-down menus, for example, have a fixed seed for every generation, the same seed, or increment or decrement

07:26Increment means it goes up one number, decrement means it goes down one number, so you can see in these choices here, we have different kind of data inputs here, we have a pop down

07:40Menu, while here we have a number

07:43These are full numbers with no decimal point, and down here for the CFG, for example, we do have numbers where you can have a decimal point in there, so these are called floats, and these are called integer numbers

07:57Then you have a sampler in here, you see it's a long list

08:02There's also a filter here where you can search for what you want to use, and then below that you have a scheduler

08:07Now, this is something you don't have in Automatic 1111, and this here actually gives you more freedom

08:14First of all, you can see there's more schedulers in here, but then also you can combine them any way you

08:20Want, so for example, when you go in here and you have, for example, DPM Plus+ SDE, there is no Karras version, because you select this and then separately you select Karras in here, so this gives you more combination, more abilities for experimentation

08:38Below that, we have the Denoise, that is similar to image to image rendering, so basically, in any step in ComfyUI, you can do image to image, because you want to be more flexible, you have a lot more ability inside of ComfyUI

08:55Now, how about these connection points? Here, on the left side, you will always have the inputs, on the right side, you will always have the outputs, when you Click and drag, this is turning into one of these noodles or cables, and you can let go of them, and this will suggest to you something that might be useful to connect

09:15You can also click here on search to have the search window again, if you want to search for something else

09:22Another functionality that you have in here that is often very important is called the reroute

09:25Now, this gives you this little element here

09:28Now, the interesting thing, let's move this over here, is I can, for example, let's create a little bit more routes here and pretend that these are other notes that we are using for other things

09:41Now, let's say I

09:43Have another K sampler down here, let's simply copy that down here, and I want to reconnect all of these to the second K sampler instead of the first one

09:54Instead of going through all of them, I can simply go now like this, and I've switched everything, so that is very useful, but there's also a second important purpose for these reroute nodes

10:06This can give you a lot more clarity in your workflow, so let's say for example the cable runs like this, and I have a node sitting here like that, so this is going behind the node, and it might get very confusing of what's actually happening, so instead you can use these

10:23Reroute nodes to have this go around that, and by that, creating more clarity

10:29Now, there's also another reason for using these reroute nodes, and that is to make your workflow cleaner and easier to understand

10:37So, for example, here you can see we have a lot of cables that go all over the place

10:41This can become very visually cluttered, so instead, we can use this reroute node to put it simply closer to it, and by that, we have only one cable going over here, while the others simply go to the other nodes in a shorter path, and this makes it much easier to understand

10:59Now, let's have another look at our starting note here, because There's a lot more you can do with that

11:06You can see here on the left side, we only have four different inputs, and then all of these choices, but what if you want to have, for example, the seed being controlled from the outside? An example for that could be that you're using multiple K-sampler, but you want to use the same seed in each of these K-samplers

11:24So for that, what you could do here is right-click, and then down here, you have a selection of convert seed to input

11:31So all of these controls can be converted to input, so when I click on that, you can see that now the seed is gone, and I have an input for that, so I can now

11:41Create a seed node and connect that, and as I said before, here we have now two K-sampler nodes that are fed by the same seed, so when this is randomized, it is creating one randomized number that then is going out to both of these K-samplers, so both of them always use the same seed number, and that can be very helpful

12:04If you no longer need that input, you can always right-click again and then set this back, so down here you see "Convert seed to widget," so when you click on that, this is removing the input, and now you have here the setting again inside of the K-sampler

12:21There's also more things you can do to customize your node

12:26For example, you can change the title up here

12:28For that, right click, go to title, and then in here, you can add something

12:33Now, I would suggest to you to keep the original name and then add something behind that

12:38For example, let's say anime, so this is, for example, the K sampler for the anime style that we want to create, so that you know what kind of node it is and also what it is for

12:49This is important, so you have clarity over what is happening, why you're using it, especially when you come back to your workflow days or weeks later

12:58Another thing you can do to create more visual clarity is to change the color of

13:03Your nodes, so you right click again, you can see here we have color, and with that, for example, I can change this to green, and you could, for example, switch all of your K Samplers over to green, so when you look at your workflow, you know exactly where all of the K sampler nodes are

13:20Another thing you can do to stay better organized is to create groups of noes

13:24For that, you want to right-click on the canvas, and then select add group

13:29This will give you a colored box

13:31I often put this above my notes, and then you can drag this out over all of the notes

13:37If you want, you can make it a little bit shorter, and then move the notes inside now

13:40This gives you an area that now combines all of them together, so you can move them around together

13:48You can also bypass all of them together, so you can right click here and then select bypass group notes

13:56Everything is going to turn violet, this means it's bypassed, it's not being used at the moment, and you can undo that by again right clicking and then select set group notes to always like this

14:06Now here's a fair warning, this is a sticky area, so that means if you move this area over any other note, even if you only touch it a little bit, it will become part of the note, so you have to be a little bit careful where

14:22You're putting your groups, and if something sticks to it, you can simply move it out of the way, and then it's outside of the group again

14:32Also, for any individual note, you can also bypass them

14:35You do that by right clicking on the individual note, and then select bypass, and if you want to reactivate them again, right click on the note, and in this case, also select bypass, and this will activate them again

14:47This also works for notes inside of groups, so you can turn off individual notes inside of a group

14:56Thanks for watching, and check out my next lesson

14:58Oh, you're still here? So, uh, this is the end screen, there's other stuff

15:03You can watch like this, or that, really cool

15:05And yeah, I hope I see you soon

15:08Uh, leave a like if you haven't yet, and well, um, yeah.
