What is Text-to-Video AI?
Text-to-video AI uses artificial intelligence to automatically transform written content into complete video productions. Instead of manually creating scenes, recording voiceover, and editing footage, you simply provide a script and the AI handles everything.
❌ Traditional Video Creation:
- • Write script (1-2 hours)
- • Create/find images (2-3 hours)
- • Record voiceover (1 hour + retakes)
- • Edit video (3-4 hours)
- • Add music & effects (1 hour)
- Total: 8-11 hours
✅ Text-to-Video AI:
- • Paste your script
- • AI generates scenes
- • AI creates images
- • AI narrates with text-to-speech
- • AI adds animations
- Total: 2-3 minutes
⚡ Real Example:
A teacher turns a 500-word lesson on photosynthesis into a 3-minute animated explainer video. Traditional method: 6-8 hours. With text-to-video AI: 7 minutes.
How Does Text-to-Video AI Work?
Text Analysis
AI reads your script and identifies key concepts, topics, and narrative structure. It breaks long content into digestible scenes (typically 10-20 seconds each).
Scene Generation
For each scene, the AI generates a visual prompt describing what should appear on screen. Example: "A plant with roots absorbing water from soil."
Image Creation
AI image generators (like DALL-E, Stable Diffusion, or Midjourney) create visuals matching each scene description. These become your video frames.
Voiceover Synthesis
Text-to-speech AI converts your script into natural-sounding narration. Modern TTS sounds remarkably human (OpenAI's Whisper, ElevenLabs, Google TTS).
Animation & Assembly
The AI assembles everything: images become animated scenes, voiceover syncs with visuals, transitions smooth out cuts. Result: a complete video.

🌍 Democratizing Video Creation
Professional video production has always been expensive. Hiring an animator costs £500-2,000+ per minute of content. Animation software subscriptions run £200-600/year. This creates a world where only well-funded organizations can communicate through video.
Text-to-video AI changes this equation. A teacher in a rural school can create the same quality explainer video as a corporate training department. A student can build a portfolio without expensive software. A small business can compete with larger competitors' marketing.
