Before you begin, here’s a quick overview of how to move through the 5 steps of your video creation journey.
Step 1: Input Idea or Script
Step 2: Design Characters (Optional)
Step 3: Edit Storyboard
Step 4: Fine-Tune Timeline & Assets
Step 5: Preview, Download & Share
Each step guides you through a specific part of the creative process — from writing and visualizing to refining and publishing.
Now that you’re familiar with the workflow and navigation, it’s time to begin your creative journey.
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.
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.
You have two ways to start your video:
Let Crreo handle the script for you.
💡 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.
Already have a script?
Manual Script reads your text exactly, so a little structure gives you full control over what’s heard and what’s seen.
For narration-only videos, just follow the format above — the voiceover you chose reads everything outside the brackets, word for word.
If you want multiple characters to talk and appear on screen, start each line with the character’s name (e.g., Emma: Let’s begin), then set up those same characters — their look and voice — in Step 2 under the same names, so each line maps to the right character and stays consistent across scenes.
Example
| Free | Start | Grow | Pro | Ultra | |
|---|---|---|---|---|---|
| Approx. Monthly Speech Allowance | 5 Mins (5k Characters) | 60 Mins (60k Characters) | 120 Mins (120k Characters) | 240 Mins (240k Characters) | 480 Mins (480k Characters) |
💡 Tip: Manual Script gives you full control — perfect for professional creators or branded storytelling.
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:
（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 30 minutes, the system will automatically generate a script of roughly that length, regardless of how short your initial input was.
Once you’ve entered your idea, click Select style to customize your video style.
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.
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, 15 or 30 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:
| Free | Start | Grow | Pro | Ultra | |
|---|---|---|---|---|---|
| Max video duration(Per Video) | 1 Min | 10 Mins | 15 Mins | 15 Mins | 30 Mins |
Defines the target audience for your video, which affects the depth of information and the style of language used in the script.
Controls the mood and writing style of your script, helping you align it with your brand or platform.
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.
These options control how your video sounds — the voice that narrates it and the background music that enhances it.
Select the voice that will narrate your video. Choose from 200+ lifelike voices, depending on your plan.
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:
| Free | Start | Grow | Pro | Ultra | |
|---|---|---|---|---|---|
| Available Voices | Basic (6 Multilingual & 3 lively voices) | Full Access | Full Access | Full Access | Full Access |

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.
