How To Create Long Ai Cartoon Movies For FREE

Overview (goal of the tutorial)

The video explains how to create long-form (30+ minute) 3D-style AI cartoon movies for free by using a workflow that:

1. Generates a script/chapter plan with an AI prompt (Google Gemini)
2. Produces images per scene with an image generator (called “Google Flow”)
3. Turns each image into an animated talking video with a free alternative (called Kwain AI / “CoinChat/Coin” in the subtitles)
4. Assembles everything with CapCut (editing, transitions, and export)

Step-by-step workflow (technology + tools)

1) Script + scene plan generation (Google Gemini)

1. Open a new tab and search Google Gemini.
2. Paste a long pre-written prompt into Gemini.

3. Fill in:

   • Title of the movie/story
   • Number of chapters (the chosen chapter count determines video length; examples mentioned: 30/40/50; demo uses 25)
   • Setting (example: Nigerian village)
   • Nationality (example: Nigerian)
   • Accent (example: Nigerian accent; selectable)

4. After submission, Gemini outputs:

   • Character descriptions/personas (e.g., mother, village elder, twins)
   • A set of image prompts
   • A set of animation prompts
   • Speech lines for each character (under something like a “speech and animation block”)

Key output concept: Gemini structures each scene so it includes:

• an image prompt (what to generate visually),
• an animation prompt (how to animate),
• what the character says during that animation.

2) Video editing setup (CapCut)

• Download and open CapCut to assemble scenes.
• Editing can be done in other software too, but CapCut is recommended.

---

3) Generate images per scene (Google Flow)

For each chapter/scene:

• Copy the image prompt from Gemini.
• Open “Lab Google Flow” (subtitles: “Lab Google Flow”).
• Create an account if required.
• Configure:
  • Aspect ratio
    • 16:9 for YouTube long-form
    • 9:16 for TikTok/Instagram
  • Number of images per generation: set to 2
• Download the generated image (tutorial mentions downloading at “1K” quality).

These downloaded images then become input for animation.

---

4) Animate images + record speech (free alternative: Kwain AI / “Coin”)

Because the referenced animation tool (“Google Flow” animation) may require payment, the tutorial uses a free alternative:

1. Go to Kwain AI (also referenced confusingly as “CoinChat/Coin” in subtitles) and create an account (account link is sent by email).
2. Generate video using:
   • 16:9 selection
   • Create video → upload attachment (upload the generated image)
   • Paste Gemini’s speech + animation block content
3. The platform generates the video and downloads it.
4. Import the animated clip into CapCut.

Maintaining continuity across scenes (important prompt technique)

The tutorial highlights an inconsistency:

• Image prompt #1 creates a detailed scene (with full descriptions).
• For image prompts #2 and onward, the approach changes.

To create a continuous story:

• When generating scene 2+, use the previous generated/animated image as a reference.
• In the animation/image tool, add that reference image into the prompt (subtitles mention “add to prompt”).
• This helps the next scene continue from the prior one (e.g., same character appearance/positions).

---

Handling multiple characters and dialogue timing

To avoid “rushing” and unnatural AI behavior, the tutorial uses these strategies:

• Prompts are optimized so each sentence is ~10 words max.
• The animator limits clip length (subtitles claim videos over ~5 seconds aren’t allowed in that system).
• For dialogue between characters:
  • Each line generates a new image prompt, but keeps the same scene composition/character positions.
  • The speaking character alternates per line (person two replies after person one’s previous line).

---

Iteration + quality control

• If a generated scene/dialogue isn’t correct on the first try:
  • regenerate until it matches
  • keep importing the best versions into CapCut

---

Final assembly: transitions + export

Transitions in CapCut

• Choose a transition style
• Drag it onto the timeline
• Warning: don’t overuse transitions, because it may break the video

Export settings

• Click export
• Select resolution: 4K

Key “free long movie” claim

The workflow is presented as a way to produce long AI cartoon movies by combining:

• chapter count to scale length
• free image/video generation alternatives
• CapCut for editing, transitions, and export
