Transcripts

in this video I'm going to be using the

incredible flux AI image generator and

combining it with an AI video generator

to try and make some of the most

realistic looking videos I'll show you

how to generate these images for free

and I'll show you how I turn them into

videos along with other tips and tricks

okay let's get into

it so you've most likely heard of this

flux image generator the results from it

are are pretty incredible and I'll just

run through a few different websites

where you can generate these images for

free so to start off we have this

hugging space website where you can use

the flux one Dev model and it's free to

use so you can just enter in your prompt

click run and it shouldn't take too long

to generate the image I'll make sure to

leave all the links to these websites

down below so it's created this image

which most of you have probably seen

before these images have been going

viral it's because flux is able to

generate these really realistic looking

images and if you come down here you can

see the advanced settings where you get

to change the size of the image and a

few other options now this model is

really good but where it really shines

is in the flux realism model so let's

check out the realism model now I'm

running the flux realism Laura off this

website which you'll find down below

this one is paid but they do give you

two $2 worth of free credits and like

they say here for $1 you can get

approximately 29 images so with the $2

you're looking get around 63 images and

this is the prompt that I had already in

there and the image looks really good

now if you're wondering what a Laura is

a Laura is pretty much a model trained

on a bunch of different images so I'm

guessing this realism model was trained

on loads of different really realistic

looking photos like you can see in this

image so its strengths are creating

these real style images now feel free to

mess around with these options here so

if you want a kind of landscape model

you can go to 16x9 so let's have a look

at a 16x9 image and that looks pretty

good and apparently if you change the

guidance scale to lower it can make the

results a bit better so let's have a try

at two and it looks pretty good there's

a bit of a weird hand there but um yeah

I would just recommend trying trying out

different options here and that looks

pretty sweet it's got a really cool

angle to that one and then you can just

download your images from there another

website I found is xlabs AI which is

running the flux realism model as well

and here they have some really good

example images that they've made along

with the extremely detailed prompt and

this is the kind of prompt that flux

really likes it likes a good detailed

prompt and not just a bunch of keywords

thrown at it so you can always take this

prompt here and change a few words to

create it more into the image that

you're looking for but if we go down we

can see all of these images look like a

real life photo to be honest they're

really really impressive and then if you

click on playground you get to change

the options here so again you get to

change the aspect ratio the number of

outputs and all the other settings and

here is another website to generate

images which is from segm mind and I

found the images generated from this

website have been really really awesome

again this just looks like a real photo

so as you can see it's got the prompt in

there and let's try a different one so

I'll try a different aspect ratio so

let's try 16x9 you can see the advanced

parameters there as well I'll just leave

those as default so this is an image

it's generated in a 16x9 aspect ratio

and it looks phenomenal it really has

nailed that realistic kind of on stage

photo look and here I just changed it to

a young man smiling on stage and I

actually changed it from seg mind to

Atomic in the prompt so now behind him

you can kind of see the Blurred outwards

of atomic so it's pretty cool that you

can put your kind of text or logo behind

the character as well if you want to

push your images even further then you

can use renet and their true touch

realistic upscaler there is a free

version so you might as as well give it

a go so if you go to try true touch I

will drop in an image and just select

that and then I'll set my realism

strength to high select your scale level

so that will make that image bigger and

click enhance and because we're on the

free version it might take a little bit

longer than if you're on a paid

subscription and as you can see it's

added a bit more realism to the image

you don't have to do this step but if

you're looking to really maximize the

realism then definitely try this method

are you enjoying this content then feel

free to like And subscribe to our

Channel it really does help okay back to

the video and if you're struggling to

make prompts there's this awesome flux

prompt generator so I'll leave a link to

that down below also and it's pretty

comprehensive so let's have a quick look

so I've just put in a very simple prompt

here of a man speaking on stage at a

Tech conference and I'll just paste in

here also and then if you come down here

you have loads of different options so

if you choose any of these these will

help guide the final prompt so you can

pick any of these if you want a certain

angle of your image and then if you come

down to here there's character details

and if you come down to scene details

you can choose the lighting the

composition the pose the background and

down here you have style and artist so

you can choose what kind of clothes

they're wearing and photography Style

Styles there's so many different options

but you can leave them all off if you

want and I'll click generate prompt and

then it adds that prompt that I added

here and then from here click on

generate prompt with llm as you can see

it's created an incredibly detailed

prompt just from this short prompt I

gave it you can also add an image here

if you want to help control the prompt

to look more like an image of your

choice and you can choose to edit this

final prompt if you want or you can just

paste it into flux and see what it makes

and the image doesn't look too bad this

is just run through the flux image

generator and not the realism model okay

so here's a little tip if you have an

image that you really like and it's in a

square aspect ratio but you want it to

be widescreen then you can use

generative expand to change their aspect

ratio you can either use Photoshop or

adobe's Firefly which gives you a number

of free uses per month so I'm on the

Firefly website so if you drag in the

image that you want to change the aspect

ratio of all you need to do is go to

expand and then drag out the sides or

down here you can choose which aspect

ratio and then click on generate you can

put in a prompt but I like to just leave

it blank just so it kind of looks at the

area and fills it in with what it thinks

should go there okay so it gives you

three results and they all look pretty

good to be honest now you might be

wondering why would I want to change it

to a wide aspect ratio and the reason is

because some video generators only work

with 16x9 aspect ratio ratio videos now

let's have a look at taking some of

these images and turning them into

videos I will take a few different

images and run them through a few

different video generators so I'll use

Runway cling and Luma dream machine I'll

run them all with the same image first

with no prompt just to see what they

create with the image and then I can

fine-tune it with prompts if I need to

so starting off with Runway I'll go on

get started and I'll choose the recently

released gen 3 Alpha turbo so I've got

the image of this man on stage and I'll

choose to generate 5 Seconds worth with

no prompt and in cling AI I'll go to

image to video I'll drag in the same

image I'll choose professional mode

again I'll leave the prompt blank on

this one and I'll click generate and

I'll do the same in Luma I've added the

image in I'll leave the prompt blank for

this one I'll try one with and without

enhanced prompt so let's check out the

results okay so this is the runway

version I think it looks really good

apart from a few things as you can see

it's kind of made a floating mic on his

face which is pretty weird but I can

understand where they're coming from

with this technique as normally people

on stage have a mic on them as you can

see his hand morphs into a hand with

less fingers on it so that's not great

but again this is just the first result

I got other than those errors I think it

looks very very very realistic okay so

now let's have a look at King's version

it doesn't look too bad now the problem

is the face is definitely kind of

morphing but otherwise the movement of

the person is very realistic now let's

have a look at lum's version okay so

this is the one with enhanced prompt

ticked on it even though I didn't add a

prompt this one I don't think looks very

good it's got weird hand morphing and

his face just looks like he's having a

Out of Body Experience for some reason

and this is the one without enhan

prompt it's uh definitely something okay

so this is what happens when you don't

prompt it it's uh yeah it does this very

very

interesting okay so now I'm going to try

with a few different prompts and I'll

show you the results so this is the

Runway video and I gave it a prompt of

man on stage talking in slow motion now

the reason I've put slow motion is

because sometimes it was giving erratic

movements so it was just to kind of slow

everything down and I'm really happy

with the result again it's doing this

weird thing with the mic on his face but

I'm sure you could get rid of that

otherwise it looks incredible the hands

do morph slightly but otherwise they

remain more realistic than the previous

video now let's have a look at Luma with

the same prompt this is with enhanced

prompt on and it just doesn't look that

good it's morphing all over the place

and it is really disfigured and here's

with enhance prompt off and I think it

looks a lot better apart from the hand

getting really weird you could crop in

and just use the face and it doesn't

look too bad it's got a really nice

camera movement to this one like it's

kind of orbiting around the character

now let's have a look at King's version

with the same prompt and it's not that

great it hasn't listen to the slow

motion prompt I gave it and the

character just becomes this weird waxy

video game looking person this is the

problem with using video generators you

do have to probably generate five or 10

before you find one that really works

but I have to say so far Runway is

coming out with the best looking videos

I have generated more videos with

different characters so here's a few

different examples

so now let's take it to the next step

let's add a voice to these people so to

do that you can either use your own

voice or create one in a program like

11lbs and I'm going to show you two

different ways on how to get the lip

sync on your character so the first way

I'm going to show you is within Runway

when you generate a video you will see

this Lip Sync icon here or you can

access it from the main Runway page so

I'll click on that and it will ask you

to either up upload an audio file or you

can record audio straight into it using

a mic or you can type in the text to

generate the audio file so I'll try the

type in text first and then you can

choose a voice from down here so you can

choose to preview them we can't change

the inevitable but we can change how we

respond so there's some great choices

here cool so I'm going to go with James

as I feel like it fits this person

pretty well so I'll click on generate

lip sync and if the audio you provide it

is longer than the video the cool thing

is the video will just choose to Loop so

that it won't cut off your audio okay so

let's check it out hi welcome to Atomic

gains first ever live conference we have

some incredible content for you coming

up hi welcome to Atomic gains first ever

live conference we have some incredible

content for you coming up and I'm pretty

happy with how that's come out now

here's another version but with the

voice created in 11 Labs hi there how do

I sound this voice over was created

using 11 Labs I hope it sounds okay hi

there how do I sound this voiceover was

created using 11 Labs I hope it sounds

okay I'm pretty happy with how the voice

came out but you can take it a step

further and as if he's speaking in a

large room so I've actually added a

slight Echo effect to his voice I'm

using premere Pro as my video editor and

it gives you the option to make it sound

like the voice is inside a large Hall

and I'm sure other video editors have

have a similar feature and I've also

added in some ambient crowd noise in the

background and I think it sounds a lot

more realistic hi there how do I sound

this voice over was created using 11

Labs I hope it sounds okay so just by

doing a few tweaks you can make it into

a more realistic sounding and looking

video now I'm going to show you another

method on how to get lip syncing and

expressions onto your character's face

so this method is the live portrait

video to video and it's on the hugging

face website which you can find a link

to down below so I'll add the video of

that man here and then in this one I've

actually recorded myself saying a few

words if you want to try this method out

make sure your camera is locked off and

your head is a still as possible and

I've just made it easier for the

software by putting it in a square

aspect ratio and then if you come down

here there are a few options feel free

to experiment with these settings as

they can give you better or worse

results result depending on your video

for this one I'm going to leave these

two checked and just click animate video

it shouldn't take too long but will take

longer if your video is longer obviously

so let's check it out hello everyone and

welcome to Atomic gains first ever live

seminar okay I think that actually looks

really good and then from here you can

download it and what I'm actually going

to do is run it through topaz video AI

upscaler which is an awesome piece of of

software otherwise there are some free

upscales online that you can use so once

I've run it through an upscaler and

changed the sound effects like I did

with the previous video I get this

result hello everyone and welcome to

Atomic gains first ever live seminar and

I've also added in a slight handheld

kind of camera motion shake to it and

I'm really happy with how it's turned

out I've actually created a video

containing different speakers that I've

generated along with my voice that I've

turned into other voices using 11 Labs

so here is that video good afternoon

everyone it's an exciting time to be

here today because we're standing at the

intersection of creativity and

Technology a place where imagination

meets innovation in the last few years

AI has taken incredible strides

producing images that are not only

astonishingly realistic but also pushing

the boundaries of what we thought was

possible in art design and even everyday

life but how did we get here and what

does this mean for the future of visual

storytelling let's explore this

fascinating journey together I am really

happy with how they turned out so by

using flux and a video generator

combining these I feel like it gives you

some of the most realistic human videos

I've ever seen yet with the AI anyway

this is the end of the video and I hope

you can see how powerful flux is and

just the potential going forward with

creating these insanely realistic images
