Transcripts

the thing with the techniques is that

they are not obvious but you will not

believe the impact they make today my

friends I will guide you through a

five-step journey to crafting 4K or even

8K visual

masterpieces we'll uncover the deuce and

don'ts and I will share some invaluable

tips and insights for checkpoint we are

downloading real cartoon realistic this

is one of the best models here on Civ AI

for semi-realistic images Al so we will

use this fantasy style a which will

Infuse our images with mesmerizing

fantasy effects last but certainly not

least we're enhancing our images with

this detail Aura a tool designed to

significantly boost detail richness

returning to automatic 1111 I came

prepared closeup image of a female Druid

in leather armor sitting on a rock

casting a nature spell smiling I also

included zoraa with a strength of 0.8 we

start with the maximum resolution of

stable diffusion 1.5 in 768 by 768 but

hey Chris why not jumping directly to a

6x9 resolution like 768 by

432 this is tempting of course however

low resolution sacrifice detail you will

miss later on I will soon reveal a far

superior approach set your sampling

steps to 35 your sampling to DPM Plus+

to M caras and you batch count to eight

images because we want to have a nice

selection also don't use hus fix this is

crucial I cannot emphasize it enough

later in the video you will learn how

professionals upscale now press contrl

enter to render let's see what we got I

like this image already this is

interesting especially with the horns

wow this image with a portal is great

love it I like the Hound here in the

background very very much and this here

is just magnificent there's some real

crazy nature spell going on these are

all great but for the sake of

demonstration this image here will work

the best what I do now doesn't make any

sense at first but trust me it will I

save my image to disk by clicking the

save icon and then click on it to

download we sent our image over to the

image to image tab by clicking this

button this is a promising start but so

far we've just scratched the

surface for this next step we need

control net to be precise we need a

control net inpainting model you can

find it at this URL just Ure to download

both the yaml file and the pth file and

while you addit grabs the tile model too

you will see this game changer in a

later Step In Action if you have no idea

what I'm talking at the moment watch

this video first and then come back

after WS our P Druid is missing an arm

as you can see and we are going to fix

this now with in painting if you haven't

used control net in painting prepare to

be amazed hit the inpaint button and

give it a moment to load then select the

appropriate brush size and paint over

the area you wish to alter here's where

it gets exciting unlike the usual method

of changing the inpaint area to only

mask we will let control net take the

rins no need to adjust you don't even

need to change The Prompt make sure your

sampling method and steps are the same

as before prepare for some variation by

setting our batch C to four we will

leave the D noising strength untouched

for now dive into the control net

dropdown activate it and filter by

inpaint select either inant Global

harmonious or inpaint only plus llama

for the pre-processor each of them does

wonders in its way ready let's render

Behold The Magic of of control net we

will take this image here although the

hand isn't perfect I've got another

trick up for that in my sleeve I will

teach it to you when we are progressing

our journey into upscale territory soon

now send the image back to image to

image you can sure fix a lot of things

with in painting but one thing apart

from hands where stable diffusion

stumbles upon is when it comes to text

here is where this week's sponsor shines

Storia lab by Storia there are two box

is impressive but it's a textify tool

that truly captures my Fascination and

here's why you can fix any spelling

mistake made by AI image Generation all

while preserving the original art style

simply upload your image create a text

box over the area in need and type in

the correct text once you hit apply the

AI Springs into action generating

multiple version of the corrected image

isn't that impressive signing up is

effortless and they even welcome you

with free credits Storia also boasts an

impressive cleanup tool designed to

seamlessly remove any undesired elements

from an image taking this Bioshock

inspired image as our canvas we simply

highlight The Unwanted figures using a

brush signaling the AI what to erase hit

apply the result is a remarkably cleaned

up image as for story our pricing it

strikes the balance between

affordability and unlimited creativity

consider the immense value this brings

to your workflow especially when

collaborating with clients on projects I

cut you a sweet deal of 10% of your

existing subscription for the first 6

month just write a mail to Founders

story. thanks again to Storia for

sponsoring this part of the video now

prepare to be amazed as we Elevate our

work from its current state to something

extraordinary we are boosting our

resolution to

1,368 by

768 to achieve a 60 by9 aspect ratio set

the D noising strength to .9 and yes you

heard that correctly the rest of the

settings can stay the same here's where

the true magic unfolds activate our unit

and check the upload independent control

image option we will upload the image we

saved earlier right

here now select inant but listen closely

choose inant only plus llama don't

choose Global harmonious this time the

later would alter our base image which

we do not want and sure control net

weight is set to one with the control

mode set to control net is more

important set the resize mode to resize

and fill failing to do so could lead to

strange images let's it render in

certain instances removing the prompt

might be beneficial I suggest trying it

with the prompt initially out of all

these images this one here stands out

the most don't hesitate to further

experiment with this it's time to take

our resolution to the next

level we need to switch the TP to a

resize bu here you will adjust the scale

between 1.5 and two depending on the

capabilities of your graphics card

personally I opt for a setting of two on

my 4080 we still keep the D noising

strength to 0.9 and yes this is still

correct in our control net tab uncheck

the upload independent control image

option and this time we need inan Global

harmonious instead of llama experiment

with a weight between 3 and 6 and set

the control mode to balanced should the

image details still not meet your

expectations consider increasing the D

noising strength to one and if that

doesn't suffice reduce the control

weight further to three or even lower

but be vary of going below

0.25 in my experience dropping beneath

the threshold should can lead to

severely disorted images let's it render

the details in the image already look

great it even fixed our hand problem but

wait until you see the last step because

so far you have seen nothing remember

the ti model we downloaded earlier well

now it's time to use it but first a

quick detour to ensure we've got all the

necessary Tools in place because we

missed some for the next step it's

important that you turn off restore

faces it's a feature that is hidden by

default in newer versions of automatic

1111 so just go to settings and here

type quick this should filter to the

Quick Settings list here type face and

select face restoration hit apply

settings and reload UI now this checkbox

up here should appear this doesn't make

any sense now but I will explain in a

moment why you need to uncheck this for

our next step head over to extension tab

click on available and load from then

type ultimate and here install the

ultimate SD upscale extension I can't

wait to demonstrate this incredible

upscale script to you only thing we need

now is to download the 4X Ultra Shar

upscaler go to this URL after

downloading it you put it in your stable

diffusion web UI folder under models and

here under ESR again and there you put

it in

now are you ready for this mindblowing

last step it's finally time to decrease

your denoising strength to 0.3 or even

lower this is trient Arrow and dependent

on your checkpoint and lowers with your

enabl control net unit click on ti/ blur

pre-processor should say tile resample

and for checkpoint it should say control

net v11 tile make sure the weight is set

to one and that control net is more

important is set now we put our freshly

installed upscale script to use go down

here and select from the script the

ultimate SD upscale don't confuse it

with the SD upscale set the target size

type to scale from image size and the

scale to two times below under upscaler

select the 4X Ultra Shar we just

downloaded for the tile widths you

should go as high as your graphics card

is able to manage I usually go with 768

but why do we do that because we do

what's called a tile up scale so we want

as little tiles as possible because it

means less seams which gives a clearer

image in general that is also the reason

we turned the restore faces off because

otherwise you will end up with images

like this instead of that now it's time

to be amazed let's render this could

take quite some time

take a moment to appreciate this

masterpiece truly Splendid isn't it the

intricacies the depth it's clear we've

outdone ourselves in crafting this gem

yet if you're looking to take your

workflow to even greater Heights I
