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.

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.

4. Text AI Model

Determines the linguistic quality and logical depth of the generated script.

• Standard: Basic quality, fastest creation speed.
• Advanced: Produces smoother, more natural language flow.
• Superb: Delivers the highest quality, detailed and human-like narration.

💡 Tip: Use Advanced or Superb for professional-grade, fluent scripts.

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.

Non-english output requires selection of Advanced or Superb Text AI Model.

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 174+ 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.

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 / 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 2.1.

5. Subtitles

Choose where subtitles appear.

• Bottom – Default; works for most videos.
• Top – Use when 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 Next: Characters to move on to character creation.

Step 2 — Add Characters

In this step, you’ll choose or create characters to bring your story to life.

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 (Experimental)

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

This feature is currently in experimental mode and available to Pro users only.

Choose Your Story Mode

After selecting or creating your characters, you’ll decide how the story unfolds — through Dialogue Mode or Narrative Mode.

Dialogue Mode

Use this mode to make your characters speak and interact with each other. Each character will speak in first person and take turns delivering their lines, allowing for dynamic and conversational storytelling.

Perfect for scenes with exchanges, debates, or emotional interactions.

💡 Tip: You can have up to four active character slots per video.

Narrative Mode

In this mode, one narrator tells the story while other characters appear visually but remain silent (narrated story about the characters).

It’s ideal for documentaries, explainers, or third-person storytelling where a single voice drives the narrative.

💡 Tip: Only one character slot is used for voice narration in this mode.

Character Editing

Click ✏️ to edit a character’s name, description, or voice.

Click 🗑️ to delete a character.

💡 Tip: The narrator’s voice will be selected and customized later in Step 4 – Audio Editing.
