🎨 AI Tools Used in This Video:

🔹 ChatGPT – Used to generate an engaging story and break it down into 24 key scenes.
🔹 Leonardo AI – Used to create 3D animation-style images of the scenes and characters.
🔹 Kling AI – Used to convert static AI images into animated video clips.
🔹 CapCut – Used for video editing, adding voiceovers, captions, and background music.

🎬 Step-by-Step Process:

1️⃣ Story Creation with ChatGPT

First, I asked ChatGPT to generate 10 different story ideas featuring a dragon and a small boy.
After selecting my favorite story, I asked ChatGPT to break it down into 24 detailed scenes.
2️⃣ Character Design for Consistency

Since consistent character design is crucial for animation, I asked ChatGPT to describe each character’s appearance in detail.
I saved these descriptions in Microsoft OneNote and refined them for accuracy.
3️⃣ Generating 3D Animated Images with Leonardo AI

I copied the scene prompts from ChatGPT and pasted them into Leonardo AI.
Before generating each image, I replaced generic character descriptions with the detailed ones from OneNote.
I used the Phoenix 0.1 model with a 16:9 aspect ratio for the best animation-style results.
4️⃣ Animating Images with Kling AI

After downloading all AI-generated images, I uploaded them one by one to Kling AI.
I described each scene in the Kling AI prompt box and clicked Generate to transform static images into motion clips.
5️⃣ Editing & Adding Voiceover in CapCut

I imported all video clips into CapCut and arranged them in sequence.
I asked ChatGPT to generate a short voiceover script based on the 24 scenes.
Using CapCut’s text-to-speech feature, I selected the Adorable Girl voice and generated voiceovers for each scene.
6️⃣ Final Touches – Music, Captions & Export

I added background music and sound effects (downloaded from Pixabay).
I included captions to enhance storytelling.
Finally, I exported the video in 4K resolution for the best quality.
