How to Create AI Explainer Videos: Complete OpenArt Guide 2025-2026

In August 2025, OpenArt—a startup founded by former Google employees—launched one of the year's most game-changing features: one-click story generation. In seconds, you can transform a single sentence, a script, or even a song into a fully animated, one-minute video complete with character consistency, background music, and a complete narrative arc. Whether you're an educator, marketer, content creator, or entrepreneur, this democratizes video production in ways previously impossible.

This comprehensive guide reveals exactly how to create professional AI explainer videos using OpenArt's revolutionary tools.

What Is OpenArt and Why It Matters

OpenArt is an all-in-one AI creative platform founded by former Google employees with 6 million monthly active users. While known for image generation with 109+ models, its breakthrough 2025 feature is one-click video generation—specifically designed for explainer videos, music videos, and character vlogs.

The platform recently raised $5 million from Basis Set Ventures and DCM Ventures, and maintains positive cash flow with revenue projections exceeding $20 million annually. This financial stability and backing from top-tier venture capital confirms OpenArt's legitimacy and commitment to continuous development.

The Problem OpenArt Solves:

Creating explainer videos traditionally requires: scripting, storyboarding, filming or creating assets, voice-over recording, animation, music selection, editing, and color grading. A professional explainer video costs $1,000-$10,000 and takes weeks to produce.

OpenArt reduces this to: write a script → click "Generate" → done in seconds. The AI handles all production complexity automatically.

Understanding OpenArt's One-Click Story Feature

Launched in open beta in August 2025, one-click story generation offers three templates:

1. Character Vlog:

Upload a character image + write a prompt → AI creates a vlog-style story

2. Music Video:

Upload a song → AI interprets lyrics and generates animations matching thematic elements

3. Explainer:

Input a text script → AI produces a fully animated explainer video

Each creates one-minute videos with character consistency, automatic music, and narrative coherence—something earlier AI video tools struggle with.

Step 3: Write or Import Your Script

This is the foundation of your explainer video.

Option 1: Write Your Script Directly

• Click "Write Script" or "Enter Script."
• Type your explainer content. Example:

Pro tips for scripts:

• Keep it concise (1-2 minutes of narration)
• Use simple, clear language
• Break into logical sections (intro, 2-3 main points, outro)
• Include a clear call-to-action

Option 2: Use OpenArt's Script Generator

• Enter a topic: "How cryptocurrency blockchain works"
• Select a style: Professional, Educational, Casual, Entertaining
• Click "Generate."
• OpenArt creates a ready-to-use script in seconds.
• Edit if needed, then proceed.

Option 3: Upload Existing Scripts

• If you already have scripts from other sources, copy and paste them directly.
• The script doesn't have to be perfectly formatted—OpenArt handles it.

Step 4: Customize Your Explainer Settings

Before generating, configure your explainer's visual style.

Choose Visual Style:

Select from pre-set visual styles:

• Minimalist (clean, modern)
• Vibrant (colorful, energetic)
• Professional (corporate, formal)
• Cartoon (playful, animated)
• Technical (technical diagrams, charts)

The style affects everything from character animation to background design.

Select Aspect Ratio:

• Vertical (9:16) for mobile and TikTok
• Horizontal (16:9) for YouTube and web
• Square (1:1) for social media posts

Choose Narration Style:

• Professional narrator (clear, authoritative)
• Casual narrator (friendly, conversational)
• AI-generated voiceover or your own voice (with voice upload)

Add Background Music:

• Select from OpenArt's music library or upload your own
• Specify tempo (upbeat, moderate, slow)

Step 5: Upload Character (Optional but Recommended)

For character consistency throughout your video, upload a character image.

• Click "Upload Character" or "Choose Character."
• Upload an image of your character (PNG, JPG, up to 10MB).
• OpenArt analyzes the image and creates a trained model.
• Processing takes about 10 minutes.

Alternatively:

Choose from OpenArt's library of 120+ pre-built characters (SpongeBob, Naruto, Disney characters, etc.). These are instantly ready—no training required.

Step 6: Generate Your Explainer Video

You're ready. Time to create.

• Click "Generate Video" or "Create Story."
• OpenArt begins processing. This typically takes 30-90 seconds depending on:
  • Video length
  • Complexity
  • Current server load

Behind the scenes, OpenArt:

1. Analyzes your script and breaks it into scenes
2. Generates AI images for each scene matching the narration
3. Converts static images to video clips using Kling 2.1 (advanced video model)
4. Maintains character consistency throughout
5. Adds background music and voiceover narration
6. Edits clips together with transitions
7. Renders final video

Your complete, production-ready explainer video appears in seconds.

Step 7: Preview and Edit Individual Clips

Perfection often requires refinement.

Preview Your Video:

• Click "Play" to watch your generated explainer.
• Check for pacing, character consistency, and overall flow.
• Listen to the narration and music synchronization.

Edit Individual Clips (Storyboard Mode):

• You see each scene individually.
• For any clip you want to change:
  • Hover over the clip
  • Click "Edit This Clip"
  • Modify the prompt (e.g., "change the background to a sunset")
  • Click "Regenerate Clip"
• The AI regenerates only that clip, preserving the rest of the video.

Examples:

• "Add more emphasis to the speaker's facial expression"
• "Make the background more professional"
• "Add animated text overlay saying 'Watch this'"

Reorder Clips (If Needed):

• Drag and drop clips to rearrange the video sequence.
• Add or delete clips as needed.

Step 4: Cover and refrigerate for 12-24 hours. Step 5: Strain through a fine filter. Step 6: Dilute with water or milk. Your smooth, cold brew is ready."

Result: Step-by-step visual guide with clear instructions, perfect for YouTube or social media tutorials.

Advanced Tips for Professional Results

Tip 1: Script Structure Matters

Strong explainers follow this structure:

• Hook (first 5 seconds capture attention)
• Problem statement (what challenge does this solve?)
• Solution (how does it work?)
• Benefits (why should viewers care?)
• Call-to-action (what should they do next?)

Tip 2: Use Specific Character Consistency

• Upload your own character if you want brand continuity.
• Use the same character across multiple explainers for channel consistency.
• This trains viewers to recognize your brand.

Tip 3: Leverage Music for Emotional Impact

• Upbeat music for energetic, fast-paced explainers
• Calm music for educational, detailed explainers
• Professional music for B2B and corporate content

Tip 4: Batch Generate Multiple Versions

• Create 3 variations with slightly different scripts.
• Test which performs better on social media.
• Use data to refine future videos.

Tip 5: Use Technical Terminology Accurately

• AI models are good at understanding professional jargon.
• Your prompts can include technical details that translate to visuals.
• Example: "Show a network diagram with nodes and connecting lines" works well.

Common Mistakes When Creating AI Explainers

Mistake 1: Overly Complex Scripts

• AI works best with clear, simple narratives.
• Avoid convoluted explanations or too many concepts.
• Keep it focused and easy to follow.

Mistake 2: Not Editing Generated Videos

• First-generation videos often need tweaks.
• Use storyboard mode to refine individual clips.
• This 5-minute step dramatically improves final quality.

Mistake 3: Ignoring Pacing

• Videos that move too fast overwhelm viewers.
• Slow videos lose attention.
• Find the right pacing for your audience.

Mistake 4: Poor Quality Characters

• Low-resolution character images produce poor results.
• Use high-quality, well-lit character images (minimum 512x512 pixels).

Mistake 5: Mismatched Voiceover and Visuals

• If adding your own voiceover, ensure it's clear and well-paced.
• Mismatch between narration speed and visual changes feels jarring.
