In this video I will help you to create a good prompt for your generation.

00:04

So we will start by filling the image.

00:07

Okay, so normally you have your own character.

00:10

You will use for example this character, this character has a name.

00:14

Okay, Melvin.

00:15

Then I will use the still reference.

00:17

So for example, this video where this man is burning an iPhone and I will then want for me to burn the logo of cursor.

00:27

So how I will ask this.

00:29

So you don't really need to ask to replace the character because this will be done automatically.

00:35

But you can say replace the iPhone by the cursor logo.

00:43

And you can make parenthesis image 1 because this prompt will have the name of the image.

00:51

So here image one as a reference.

00:53

So here replace the iPhone by the cursor logo image1 and you can add then some specificity like with plain white backgrounds.

01:07

So then you can click on this generate and generate first variation.

01:12

You need to take care because each variation is a cost.

01:16

So in the beginning I will advise you to only choose one variation and to avoid to create three, four or more variation at once because it may be a bad result because your prompt is bad.

01:32

So after we validate the prompt, we validate the image, we can increase the number of generation.

01:37

So yeah, we have the result.

01:39

It's pretty good.

01:40

We can see that the prompt work really well in general everything is good and the logo is good, is in 3D and we already have a good result.

01:50

Okay, so here we can just iterate, maybe change the shadow.

01:54

But I really like already the result.

01:56

We can see that the background is respected.

01:58

I will show you another example with more item.

02:02

So this second example showed this thumbnail, as a reference.

02:05

So I will just show it to you.

02:08

So it's like this.

02:09

It's me shocked with this logo with move to trash and here another logo.

02:14

So here I have image one image two and I will have this reference and I will write image.

02:21

Image2mistrallap Replacing the current Gemini icon.

02:26

Okay, so here we have Gemini icon.

02:28

And I ask Precisely that the image 2 will replace with write and mistral 2 the logo move to trash contain the image 2.

02:39

here the image 1 the cloth logo background stay neutral.

02:44

So as you can see, I didn't ask to replace the character.

02:47

I didn't ask anything specific.

02:50

I just asked the thing I want to change because he know that he need to use these references.

02:55

He know that he need to use this person and he know that he need to use this image.

02:59

So with this I get these three results.

03:02

So we can see that it's pretty good.

03:03

For example, this one that I like, if we click, we can see that he replaced the logo with Mistral.

03:10

He replaced this with cloth and he had a shitty background that you can ask to remove or something.

03:16

And at the end I get this result.

03:17

That was pretty good.

03:19

So here you can always reference image by using the name and you don't need to add any other information.
