How to Use Crreo AI Video Maker

Using the Stepper Navigation

You can move backward to review or edit any previous step.

You can move forward again up to the latest completed step.

Navigating along the stepper does not regenerate any assets — your existing content remains unchanged.

Step 1 — Describe Your Idea or provide manual script

In this step, you define what your video is about — it’s the foundation of your story.

You can either let AI create the script automatically or paste your own video script.

Choose Your Script Mode

You have two ways to start your video:

Option 1: Auto Script

Let Crreo handle the script for you.

1. Click Auto Script — the system will create a full, ready-to-use video script for you.
2. Enter a short description of your idea in the Points to cover box.
   Example:
   “I want to explain the process of making sparkling wine at home. I want to turn it into a step-by-step and easy-to-follow guide. The main steps are: selecting suitable grapevines, growing them at home backyard, identifying the right time to harvest the grapes, nailing the fermentation process, and safe bottling of sparkling wine.”

💡 Tip: A clear and focused idea helps the AI craft a more accurate and engaging script. Try to summarize your main message in one or two sentences — what story you want to tell, what the viewer should learn or feel, and any specific scenes or moments you imagine. The more direction you give, the more the AI can match your vision.

Option 2: Manual Script

Already have a script?

• Click Manual Script, then paste or type your content directly.
• You can break it into scenes, or simply provide the full narration.

💡 Tip: Manual Script gives you full control — perfect for professional creators or branded storytelling.

Manual Script vs. Auto Script: What’s the Difference?

Manual Script Mode

In Manual Script mode, the system uses your exact input — without expanding, rewriting, or shortening your text.

The video length in this mode fully depends on the length of your provided script. You can roughly estimate the duration by checking your word count:

For example:

• A script with 600 words will produce a video of approximately 4 minutes.
• To create a 10-minute video, you’ll need a script of around 1,500 words.

（On average, normal speech speed equals about 150 English words per minute.）

Auto Script Mode

In Auto Script mode, the AI automatically expands your input — whether it’s a short phrase or a paragraph — into a complete script.

The video duration is determined by the “Duration” setting in the Customize Menu.

For instance, if you select 15 minutes, the system will automatically generate a script of roughly that length, regardless of how short your initial input was.

Video Options Setup

Once you’ve entered your idea, click Select style to customize your video style.

Auto Script Settings

When using the Auto Script mode, these options determine how the AI creates your video script — including its content, tone, and language.

The following settings are only active in Auto Script mode and do not affect Manual Script.

1. Duration

Choose the total length of the video you want to generate. The AI will automatically adjust the script length to match your selection.

Available options: 1, 2, 3, 5, 10, or 15 minutes.

💡 Tip: For short-form content, 1–3 minutes is ideal. For tutorials, explainers, or storytelling videos, consider 10 minutes or more.

Different plans offer different maximum durations:

2. Audience

Defines the target audience for your video, which affects the depth of information and the style of language used in the script.

• Novice: Designed for beginners audience, with simplified explanations of basic concepts.
• General: Default option for a broad audience.
• Expert: For a professional audience, using more technical and in-depth language.

3. Tone

Controls the mood and writing style of your script, helping you align it with your brand or platform.

• Casual: Natural and relaxed — perfect for social media.
• Formal: Professional and structured — ideal for corporate or educational content.
• Informal: Friendly and conversational — closer to spoken language.
• Creative: Expressive and narrative — best for ads or storytelling.
• Humorous: Playful and entertaining — great for lighthearted videos.

5. Change Language

If you want your script to be generated in a language other than English, simply type the desired language name.

Example: Enter “Spanish” to generate a Spanish-language script.

Audio Settings

These options control how your video sounds — the voice that narrates it and the background music that enhances it.

1. Default Voice

Select the voice that will narrate your video. Choose from 250 lifelike voices.

You can click Hear Sample to preview the voice before generating.

💡 Tip: A clear and calm voice works best for tutorials or product explainers, while a lively tone fits social videos and ads.

Available by plan:

2. Background Music

Add background music to make your video more engaging.

You can adjust the volume level of background music:

• Off
• Auto
• Quiet
• Medium
• Loud

Video Settings

These settings define how your video looks — its resolution, style, and generation mode.

1. Size

Choose your video’s aspect ratio and resolution.

• 1280×720（16:9） – Horizontal format, ideal for YouTube or presentations.
• 720×1280（9:16） – Vertical format, ideal for TikTok, Shorts, or Reels.

2. Style

Select the overall visual style of your video.

• No Style – The system automatically selects a suitable visual style for your video based on the content and theme.
• Custom Style – Enter any specific artistic style (e.g., “Ghibli style,” “Pixar 3D”).
• Photo-realistic – Highly realistic; great for product or people.
• Cinematic – Dramatic lighting and mood; stronger storytelling.
• Fantasy – Imaginative, fantastical visuals.
• Painting – Artistic/oil-paint feel.
• Drawing – Hand-drawn look; great for education/animation.
• Illustration – Clean graphic look; great for infographics/tutorials.
• Cartoon – Animated character style; playful or kid-friendly.
• Sketch – Black-and-white linework; concept or prototype feel.

3. Image Model

Choose the quality and detail level of generated visuals.

• Kalo S
• Kalo M
• Kalo L
• Kalo XL

💡 Tip: Use Kalo XL for final high-quality outputs; Kalo S for quick drafts.

4. Video Mode

Defines which rendering engine the system uses.

• Images – Generates still images only.
• Kine 1.1 / Kine 2.1 / Kine 2.2 – Different generations of the Kine video engine.

Kine 1.1 is an upgraded version of Kine 1, offering cleaner visuals, smoother motion, and more realistic physics.

Kine 2.1 is an enhanced version of Kine 2, excelling in precise understanding and high visual consistency — ideal for complex narrative videos.

Kine 2.2 builds on Kine 2.1 with faster generation speed, improved motion accuracy, and better handling of vertical compositions.

💡 Tip: For the best animation quality and overall visual performance, we recommend using Kine 2.1 or Kine 2.2.

5. Subtitles

Choose where subtitles appear.

• Bottom – Default; works for most videos.
• Top – Use when the bottom is visually busy.
• None – No subtitles.

6. Transition effects

Add smooth transitions between scenes for a more cohesive viewing experience.

• None — No transitions applied.
• Auto — System automatically selects suitable transitions based on your scenes.
• All Same — Applies one consistent transition style to all scenes.

After completing your script and settings, click Add Characters to move on to character creation.

Step 2 — Add Characters

In this step, you can create or select characters that will appear in your video.

Characters help maintain visual consistency, narrative clarity, and storytelling depth across your scenes.

You can skip this step if your video doesn’t require specific characters.

Text-based Characters

Describe your character in text — including appearance, style, and personality — and the AI director will keep that character consistent throughout the story.

This option is available to all users and is perfect for quick character setup.

Photo-based Characters

Uses the actual character appearance to ensure stronger visual consistency across all scenes.

This feature is currently available to Grow plan and above.

How it works:

• Create from scratch – Describe what you need and generate a character from a prompt. Refine and adjust until it matches your vision.
  
• Upload your own image – Toggle to “Photo-based” mode (Pro plan only) to use a real image as your visual anchor. This gives you tighter control and noticeably better visual consistency across scenes.
  
• Choose from Crreo library – Select a ready-made character for instant use. Perfect for faster setup and rapid prototyping.
  
• Assign voices – In Dialogue Mode, assign voices to each character. In Narrative Mode, use your selected narrator voice from Step 1.
  
• Save to your library – Reuse your characters across projects for consistent storytelling and brand continuity.
  
• Choose your story mode – Supports both Narrative and Dialogue modes, with up to 4 characters per video.

Dialogue Mode

Make your characters speak and interact with each other.

Each character speaks in first person and takes turns delivering their lines.

Perfect for conversations, debates, and emotional exchanges.

Narrative Mode

A single narrator tells the story while other characters appear visually.

Ideal for documentaries, explainers, and third-person storytelling.

After completing your character setup, click “Generate Storyboard.”

The AI Director will automatically generate a complete storyboard based on your script and character settings, maintaining visual and narrative consistency throughout.

Step 3 — Finalize Storyboard

In this step, you’ll review and customize your storyboard — the visual and narrative structure of your video.

It is important to validate or update your scene visuals as they are used in the following steps to create scene visual assets. In the top-right corner of each generated image, you’ll find four icons (left to right):

1. Download — Save the current image to your device.
2. Upload — Upload your own custom image to replace the generated one (must be in a resolution matching your video — either 1280×720 for horizontal videos or 720×1280 for vertical videos).
3. Edit Image — Refine or modify your images without starting over (Available on paid plans).
   
   The Edit Image feature allows you to make targeted changes to a generated or uploaded image while keeping the overall look consistent. With precise control, you can:
   • Adjust any element in a scene (text, objects, background details, etc.)
   • Match colors or mood to your preferred style
   • Swap faces seamlessly
   • Customize any part of the scene you can describe
   Simply type a prompt to describe the change you want and update the image in seconds.
