Generate educational video presentations with AI-generated content, animations, and voice narration by simply entering a topic.

​
Overview

The AI Video Presentation Generator creates complete video presentations by:
  • Generating structured slide content from your topic
  • Adding professional animations for visual concepts
  • Creating synchronized voice narration
  • Combining everything into a downloadable MP4 video

​
Starting a New Presentation

1

Enter your topic

On the home screen, enter a specific topic in the Topic / Prompt field.
Be specific for better results. Use descriptive prompts like “Explain Newton’s Third Law of Motion” instead of just “physics”.
Example topics:
  • “Explain photosynthesis in plants”
  • “How does blockchain technology work”
  • “The water cycle and its importance”
The topic field is located in frontend/src/components/Home.jsx:878

Configure presentation settings

Adjust these parameters to customize your presentation:Number of Slides (3-10)
  • Default: 5 slides
  • Determines presentation length
  • More slides = more detailed coverage
Language
  • English (default)
  • Hindi
  • Kannada
  • Telugu
Tone
  • Formal: Academic, professional style
  • Casual: Conversational, friendly approach
  • Enthusiastic: Energetic, engaging delivery
These settings are configured in frontend/src/components/Home.jsx:891-939

Click Generate Video Presentation

Click the Generate Video Presentation button to start the generation process.The system will:
  1. Send your request to the backend API (POST http://localhost:8000/api/generate)
  2. Generate slide content using AI
  3. Create animations for visual concepts
  4. Generate voice narration
  5. Compile everything into a video
Button implementation: frontend/src/components/Home.jsx:972-983

Monitor generation progress

During generation, you’ll see a loading indicator showing:
  • Spinning animation
  • Status message: “Generating your presentation…”
  • Reminder to check backend console for detailed logs
The process typically takes several minutes depending on:
  • Number of slides
  • Complexity of animations
  • Server performance

​
What Happens During Generation

​
Content Generation

The AI analyzes your topic and creates:
  • Title slide: Introduction with topic overview
  • Content slides: Key concepts with explanations
  • Conclusion slide: Summary and key takeaways
Each slide includes:
  • Clear, focused title
  • Structured content (bullet points or paragraphs)
  • Duration estimate for narration timing

​
Animation Selection

For certain topics, the system automatically generates animations:
  • Physics concepts: Force diagrams, motion illustrations
  • Mathematical concepts: Geometric proofs, equations
  • Algorithms: Flow diagrams, step visualizations
Animations are generated using Manim (Mathematical Animation Engine) as defined in backend/generators/manim_generator.py
Not all slides get animations. The AI determines which concepts benefit most from visual animation.

​
Voice Narration

The system generates natural-sounding voice narration that:
  • Explains each slide’s content
  • Matches your selected language and tone
  • Synchronizes with slide timing
  • Uses text-to-speech technology

​
Video Compilation

All elements are combined into:
  • Standard MP4 format
  • 1080p resolution
  • Synchronized audio/video
  • Professional transitions

​
Viewing Your Generated Video

Once generation completes:
  1. The interface automatically transitions to the video player
  2. Your video starts playing with full controls
  3. You can see the slide timeline on the right
  4. All slide content is displayed below the player
Video player implementation: frontend/src/components/VideoPlayer.jsx

​
Generation Best Practices

Choose the right number of slides
  • 3-5 slides: Quick overview or simple concepts
  • 5-7 slides: Standard educational content
  • 8-10 slides: Comprehensive, detailed explanations
Write effective prompts
  • Include specific concepts you want covered
  • Mention the target audience level if relevant
  • Use action words: “Explain”, “Demonstrate”, “Compare”
Language and tone selection
  • Match language to your audience
  • Use formal tone for academic content
  • Use enthusiastic tone for engaging, motivational content

​
Common Issues

Generation takes too long
  • Check your internet connection
  • Reduce number of slides
  • Simplify your topic prompt
  • Check backend console for errors
Generation fails
  • Ensure backend server is running
  • Verify API keys are configured
  • Check topic doesn’t contain invalid characters
  • Review backend logs at backend/main.py
Video quality issues
  • Generated videos are 1080p by default
  • Quality depends on animation complexity
  • Check available disk space for rendering

Technical Details

​
API Request Structure

The frontend sends this request to start generation: 
axios.post("http://localhost:8000/api/generate", {
  topic: "Your topic here",
  num_slides: 5,
  language: "english",
  tone: "formal"
})

​
Response Data

On success, the API returns: 
{
  status: "success",
  content_data: { /* slide content */ },
  script_data: { /* narration scripts */ },
  video_path: "path/to/video.mp4",
  video_filename: "topic_video.mp4"
}

​
Backend Processing

The backend orchestrates:
  1. Content generation via AI model
  2. Animation code generation (if applicable)
  3. Manim rendering for animations
  4. TTS (Text-to-Speech) for narration
  5. Video compilation using FFmpeg
Main generation logic: backend/main.py
