In this video, you're getting a full step-by-step guide on how to make your own AI cartoon videos,

even if you've never done anything like this before.

By the time you're finished,

you'll be able to create results just like this.

And honestly, it's easier than you'd think.

And the reason this matters so much right now is because these videos aren't just fun experiments with AI.

They're one of the fastest ways to grow online today.

They can rack up thousands,

even millions of views across YouTube shorts, TikTok, and Instagram.

And that attention can translate directly into real money through monetization,

brand deals, and entire businesses you can build on top of your content.

So if you've been waiting for a complete tutorial that takes you from zero to a finished AI cartoon video,

this is it.

This is exactly what I'll be walking you through today.

So the way we're going to be creating these AI cartoons is basically in four steps.

First of all, we're going to create the script.

And while we're doing that,

I'm also going to teach you exactly how to write a good cartoon script yourself.

Plus, I'll give you an AI template that makes the whole process easier.

After that, we'll move into the image generation part.

That's where we'll actually start turning the script into visuals,

using a secret tool that makes the whole process easier.

Then once we've got the images,

we'll convert them into videos,

so you're not just stuck with static pictures,

but you actually have a moving cartoon.

And finally, the last step is doing the voiceover,

which is what really brings everything together and makes it feel like a finished cartoon.

So by the end of this video,

you're going to know exactly how to put everything together into a complete cartoon video that you can post online,

pretty much anywhere.

Now, let's start with the first step,

which is writing the script.

To write a good cartoon script,

we need a couple of key things in it.

First, we need a hero,

so someone the audience will be rooting for.

Then we need a villain,

someone the hero is going to defeat.

And then finally, we need it to be a super simple,

easy-to-follow story that just progresses naturally toward the hero finally doing something great and succeeding at whatever he set out to do.

And the best way to script that is in scenes,

Because when we break it into scenes,

it gives us a really nice foundation to create the images for each scene,

and then later, to actually put them together into a video.

So for that exact thing,

I made this ChatGPT template right here.

It's really simple, but it includes everything you need to make a story work.

The hero, the villain, the arc,

and it keeps it fun,

light, and easy to follow.

Now if I copy this template into a brand new ChatGPT chat,

I can just insert my idea into the brackets.

For example, I'll write, a brave squirrel tries to save his magical acorn from a sneaky fox who wants to steal it.

Then the AI will automatically build out the story following the rules.

And here's the result it gave back.

As you can see, it made a total of seven scenes for this cartoon.

It starts off with the squirrel playing in the forest.

Then the fox shows up.

The squirrel tries to escape and hide the acorn.

And in the end, the fox loses.

Our villain is defeated and it ends with a happy victory for the squirrel.

This is honestly the best and simplest way I've found to write a script.

So now that we've got our script in hand,

let's move on and start generating some images.

And so the tool I'm going to be using to create our cartoon is called OpenArt.

The reason I'm using OpenArt is because it's basically a professional all-in-one tool that lets you do everything in one place.

You can generate images, turn them into videos,

upscale them, and even edit every asset live,

all inside one platform, which means you don't need to deal with five different subscriptions

or switch back and forth between random tools.

Everything's all in OpenArt, simple and easy to use.

Now to create our initial characters for the cartoon,

we're going to be using a feature inside OpenArt called Characters.

When you head over there,

you'll see three options for how you can start.

You can start with 4 plus reference images,

you can start with a single image,

or you can just start with a description.

If you already have something in mind for what your character looks like,

then you probably want to use one of the first two options.

But I don't have an image ready,

so I'm going to use the start with description feature.

When you open that up,

you'll see a UI where you can give your character a name,

write a description, and choose a style.

So for our main hero,

the squirrel, I'll write a small brave squirrel with big brown eyes,

a fluffy tail, and soft brown fur.

He looks careful, curious, and full of energy.

He's holding a shiny magical acorn close to his chest,

cartoon style, bright colors, with a friendly and heroic expression.

For the name, I'll just keep it simple and write squirrel.

And then I'll select a style.

This part is actually pretty cool because you can pick from different art styles.

For this one, I'll go with Pixar style,

since that's closest to what I have in mind.

Then I just hit create,

and OpenArt generates a few previews.

100

As you can see, the results look really good, exactly how I imagined.

101

I like all three of them,

102

but I think the one on the left is the best fit,

103

so I'll select that and lock in my character.

104

Now, one really powerful thing about OpenArt is that it keeps your characters consistent.

105

You can even generate two different characters and then put them into the same image together,

106

which is something most other tools struggle with.

107

So I'll let the squirrel finish generating in the background,

108

and let's go ahead and create our second character, the fox.

109

For the fox, here's the description.

110

A sneaky fox with sharp,

111

clever eyes, pointy ears, and a long, bushy tail.

112

His fur is orange with a white belly and black paws.

113

He has a sly grin that shows his mischievous nature.

114

For the name, I'll just put fox.

115

And again, I'll select the Pixar style to keep it consistent.

116

Once it's done, we get a few previews again.

117

And just like with the squirrel, they look great.

118

I like the one on the right,

119

so I'll just use that one.

120

The generation usually only takes a few minutes,

121

so it doesn't slow you down much at all.

122

Now that we have both of our characters created,

123

we can start building the actual scene images.

124

Let's start with our first scene,

125

which is just a squirrel.

126

I'll click create on the squirrel icon and it'll open up a new workflow.

127

Inside the workflow, there are a few things you need to know.

128

First, in the prompt section,

129

you basically describe what's happening in the scene and you can add your characters to it.

130

You can add your first character,

131

add your second character, and also create interactions between them.

132

I'll show you how that works in just a second.

133

Then you've got prompt adherence,

134

which controls how straight strictly the AI sticks to your description.

135

You also have character settings,

136

which let you control how closely it remembers the character and whether it keeps the clothes consistent from scene to scene.

137

So let's create our first image.

138

For this, I already made a template in ChatGPT.

139

All I have to do is paste in the scene description,

140

and the template gives me back a full image prompt I can copy over to OpenArt.

141

For example, in the template,

142

it'll say character 1 as a placeholder.

143

In my case, that's the squirrel.

144

So I just replace it with squirrel.

145

Then I'm good to go.

146

I'll set it to generate four images just to make sure we get at least one really good one.

147

And as you can see,

148

the results came out perfect.

149

The AI followed the description exactly,

150

and the squirrel came out looking just the way I envisioned.

151

Now let's move on to the second prompt.

152

This one uses a character 2,

153

which in our case is the fox.

154

To add him, I just click on the add character button,

155

and now he shows up in the UI.

156

Then when I'm writing the prompt,

157

I'll replace character 2 with fox.

158

And now let's hit create and see what we get.

159

And there we go.

160

It looks amazing.

161

Both characters show up together in the same scene, consistent with their designs.

162

And it's exactly how I wanted it to look.

163

So that's basically how the image workflow goes.

164

You go back to ChatGPT,

165

grab the prompt from the template,

166

paste it into OpenArt, and generate the image.

167

Then just repeat that for each scene.

168

By the way, if you're making actual shorts,

169

you'd normally want to set everything up in vertical format.

170

Since this is a long form video though,

171

I'm keeping it in landscape so it's easier for you to see the details.

172

Let's do the next one.

173

It's a scene with both characters,

174

so I'll replace character 1 with squirrel and character 2 with fox.

175

If you mix them up,

176

things can get weird really fast,

177

so just make sure the names are matched correctly.

178

And as you can see, it generated just fine.

179

So I'll go ahead and finish up the rest of the images in the same way.

180

Once they're all done, I'll mark my favorites with a star so they're easy to keep track of.

181

And now all the images are ready to go.

182

So to generate our videos,

183

this part is actually pretty simple.

184

We've already done the hard work by generating all the images.

185

Now all you need to do is head over to the video section in Open Arc.

186

Make sure you're switched over to the image to video option,

187

which is the one that starts off with a starting frame.

188

Then you just select your model.

189

Personally, I recommend going with Kling 2.1 or Kling 2.5,

190

since those give the best results for cartoons.

191

Google VO3 is the most realistic model,

192

but we don't really need realism here we want more saturation in the colors,

193

everything looking nice, happy, and cartoon-like.

194

So Kling is the way to go.

195

So I'll select Kling 2.5 and grab my first scene image.

196

You can do this really easily without even downloading the files.

197

Just click on history, and you'll see every image you've made already sitting there ready to go.

198

So I'll just pick the first one,

199

click confirm, and now we can write the prompt.

200

Now, you might have already noticed that when you're using the template,

201

it actually generates a video prompt for you as well.

202

So it's basically the exact same process we used for images.

203

You just grab the prompt from ChatGPT,

204

paste it into the model,

205

and then set your duration.

206

For duration, it really depends on the scene.

207

Sometimes 5 seconds is enough, sometimes you'll want 10.

208

You'll just have to think about what makes sense for the moment.

209

Once you've picked that, just click create and let's see what comes out.

210

And here we go, the result looks great.

211

The squirrel is playing with the acorn in the forest,

212

the acorn has a little glow to it,

213

and the whole thing looks really smooth.

214

The colors are bright, it feels focused,

215

and overall, it's just an incredible result.

216

Now just like we did with the images,

217

we'll go back, grab the next scene,

218

paste in the prompt, set the duration, and hit create.

219

Then repeat that process scene by scene until everything's generated and ready.

220

So I'll go ahead and finish generating all of mine,

221

and then we'll move on to the next step.

222

Alright, now that all of my videos are done,

223

you can see they came out looking amazing.

224

Everything is consistent, the characters stayed exactly the same from scene to scene,

225

and it all worked perfectly.

226

So with the videos ready,

227

we can now move on to one of the final steps in the process, creating the audio.

228

So for generating our narration,

229

we're still going to stay inside OpenArc.

230

But before that, you'll just want to head over to ChatGPT and grab all of your lines.

231

You can either copy them one by one,

232

or you can just take the whole scene script,

233

paste it into the same chat,

234

and ask the AI to give you all of the narration lines together.

235

That's what I did, it just made it easier to copy everything over in one go.

236

Then head back to OpenArc,

237

and down in the bottom left,

238

you'll see the audio section.

239

This part uses Eleven Labs as the model,

240

and as you probably know,

241

Eleven Labs is one of the best tools out there for speech generation,

242

so it works perfectly for narration.

243

I'll paste all my lines into the prompt window.

244

You can also do it one line at a time if you prefer,

245

but honestly, I think it's just easier to generate everything at once,

246

and then cut it up later in your editing tool if something doesn't line up perfectly with a scene.

247

As long as you end each sentence cleanly,

248

the AI will leave enough of a pause for you to move the lines around without any problem.

249

Now comes the fun part, picking your voice.

250

For this one, I wanted to feel like an older guy telling the story to his grandchildren,

251

So I'm gonna go with American, Male and Old.

252

That narrows it down to a few options and out of those,

253

I really like Jesse the best.

254

So I'll select Jesse and then let's walk through the settings.

255

Stability controls how steady the voice sounds.

256

If you lower it, the voice becomes stiff and monotone.

257

If you raise it, it gets more natural with a little bit of play.

258

Since this is kind of a children's story,

259

I'll set it a little higher at around 0.6.

260

Similarity boost determines how closely the AI sticks to the original voice.

261

So I'll just leave that at 0.5.

262

Then there's style exaggeration.

263

This makes the voice more animated or dramatic,

264

but I don't really want that for this story.

265

So I'll keep it very low at 0.1.

266

Finally, the speed.

267

By default, it's set at 1,

268

but I'm going to slow it down just a little to 0.9,

269

so it feels more like storytelling.

270

Once all that's set, I'll click Create.

271

This is Sammy the Squirrel.

272

He has a very special acorn full of magic and sparkle.

273

And as you can hear,

274

the result sounds really good.

275

It's exactly the type of narration I had in mind.

276

Plus, the pacing naturally leaves just enough space so that,

277

if needed, I can cut it up and move lines around in editing without it sounding weird.

278

So I'll hit the download button,

279

and now we've got all of our assets ready to go.

280

Next, I'll head over to my video editor of choice,

281

which for me is CapCut.

282

I'll open a new project,

283

drag in all my assets,

284

and start lining them up.

285

I'll put the videos in the right order,

286

add in the generated narration, and sync everything up.

287

And with that, everything is done.

288

I'll export the final video,

289

and let's take a look.

290

This is Sammy the Squirrel.

291

He has a very special acorn full of magic and sparkle.

292

But look, the sneaky fox wants to steal Sammy's magical acorn.

293

The fox creeps closer, but Sammy's ready to protect his treasure.

294

Zoom!

295

Sammy runs as fast as he can,

296

with the fox chasing right behind.

297

Sammy is clever.

298

He hides the acorn up high,

299

where the fox cannot reach.

300

Oh no!

301

The fox falls into the bushes.

302

Sammy's magical acorn is safe at last.

303

Sammy the brave squirrel saved his magical acorn,

304

and the forest is happy again.

305

The result looks very very good.

306

The video generation came out amazing and the characters stayed consistent across all the scenes,

307

which is something a lot of people skip and it ends up ruining the immersion.

308

Here, it really holds together.

309

So overall, I'd say this is a very strong result.

310

So now you know how to take an idea straight out of your head and turn it into a finished cartoon,

311

ready to post online.

312

And the cool part is,

313

you can use this to start growing really fast,

314

whether you're posting YouTube Shorts,

315

TikToks, or any other kind of short form content form content

316

and what makes this whole process even better is

317

that we did all of it inside open art with no need of switching multiple subscriptions

318

or dealing with logins everywhere everything you need is right there in one place

319

which just makes the whole workflow smoother and a lot more fun

320

so if you want to start creating your own cartoons

321

or any kind of ai content go ahead

322

and start using open art with the link down in the description thanks for watching

323

and i'll see you in the next one
