How to Create a 3D Animated Kids Video Using AI: A Step-by-Step Guide

Have you ever wondered how to create a vibrant, 3D animated kids video that looks like a Pixar movie—without any experience in animation? Thanks to advanced AI tools, it’s now easier than ever to bring your stories to life. In this guide, we’ll walk you through each step to turn your imagination into a fully animated kids video, complete with characters, voiceovers, and cinematic visuals.


🎬 Step 1: Generate Story Ideas

If you already have a story, feel free to skip this step. But if you’re starting from scratch, there’s a handy AI-powered kids story idea generator you can use. Just visit the provided link, select the theme (e.g., “Fantasy”), and click “Create Content.” The tool will instantly generate several creative ideas. Choose the one that speaks to you, and you’re ready to move on.


📝 Step 2: Create the Complete Story

Now that you have a one-line idea, you’ll want to expand it into a full script. Head over to the Story Generator Tool, paste your idea, select how many characters you want in the story, and click “Create Content.” The tool provides a detailed scene-by-scene breakdown to serve as the backbone of your animation.


👧 Step 3: Generate Character Details

Your characters need to be consistent throughout the video. To define how they look, use the Character Generator Tool. Paste your full story, and the AI will return detailed descriptions for each character including facial features, hairstyles, outfits, and more. These profiles ensure your visuals stay coherent across all scenes.


🎨 Step 4: Generate Visual Prompts

With your characters and story ready, it’s time to create the prompts that will instruct the AI to generate visual scenes. Use the Text-to-Video Prompt Generator Tool. Paste both your story and character descriptions, and click “Create Content.” You’ll receive individual prompts for each scene, perfectly tailored for animation.

🎙 Step 5: Generate Voiceover Scripts

Along with visuals, you need engaging narration and dialogues. The same tool can also create a voiceover script in JSON format, breaking down each character’s lines. Simply click “Create Content” and copy the generated script. You can then split the dialogue by character for easier voice generation.


🎥 Step 6: Generate the Visuals

Now comes the exciting part—turning those prompts into actual video scenes. Use a 3D animation tool (linked in the description) that accepts the generated prompts. Paste them in, disable the auto-refine option (to preserve character consistency), and start rendering. The platform gives you 1,000 free credits upon signup, plus 100 bonus credits daily—just make sure to use them within 3 days.


🗣 Step 7: Generate the Voiceovers

Use an AI voice generator to create voices for each character. Once you’re signed in, search for “cartoon” or “tune character voices.” Choose a voice you like, paste the relevant character’s script, and click “Generate Speech.” Download each file and repeat the process for every character.


✂️ Step 8: Edit the Video

To bring everything together, use an online editor like Clipchamp. Upload all visuals and voiceovers, drag them to the timeline, and align each scene with its respective voice clip. For added flair, include sound effects and background music. Pixabay offers a wide selection of free cartoon music and sound effects to choose from.


📤 Final Step: Export and Download the Video

Once editing is done, click Export, select your desired video quality, and download the final result. Your animated masterpiece is now ready to share with the world!
