How to Summarize Videos with AI

Why Summarize Videos with AI?

Video summarization saves hours by extracting the most important information from long recordings. Whether you’re watching lectures, attending virtual meetings, reviewing webinars, or consuming YouTube content, AI can instantly identify key points, generate structured summaries, and create timestamped chapters for quick navigation.

Key benefits:

• Time savings: Review hours of content in minutes
• Better retention: Focus on key insights without rewatching
• Easy sharing: Send concise summaries instead of full videos
• Searchability: Find specific topics instantly
• Action items: Extract tasks and decisions automatically

What AI Video Summarization Can Do

ScreenApp’s AI analyzes your video’s transcript and generates:

1. Text summaries - Concise overview of main points
2. Timestamped chapters - Organized sections with timestamps
3. Key insights - Important quotes and highlights
4. Action items - Extracted tasks and decisions (for meetings)
5. Searchable content - Find any topic within the video

Accuracy: AI summaries capture 90-95% of key information while reducing content length by 80-90%.

How AI Summarization Works

ScreenApp uses a multi-step process:

1. Upload video - Any format (MP4, MOV, WebM, etc.)
2. Transcription - AI converts speech to text with 99% accuracy
3. Analysis - Natural language processing identifies key topics
4. Summarization - AI generates structured summary with timestamps
5. Chapter creation - Auto-generates navigable chapters
6. Refinement - Edit and customize the summary

Processing time: ~1 minute per 10 minutes of video

Step-by-Step: Summarize Any Video

Step 1: Upload Your Video

1. Go to ScreenApp
2. Click “Upload” button or drag and drop your video file
3. Alternatively, use “Import from URL” for YouTube, Vimeo, or direct video links
4. Wait for upload to complete

Supported formats:

• Video: MP4, MOV, AVI, WebM, MKV, FLV, WMV, MPEG
• Audio: MP3, M4A, WAV, AAC (for podcasts, audio lectures)
• File size: Up to 5GB
• Duration: No length limit

Best for summarization:

• Lectures and educational videos
• Business meetings and presentations
• Webinars and training sessions
• YouTube videos and podcasts
• Conference talks and interviews

Step 2: Automatic Transcription and Processing

Once uploaded:

1. ScreenApp automatically transcribes the video
2. Status shows: “Transcribing…” then “Processing templates…”
3. AI analyzes the transcript for key topics and themes
4. Summary and chapters generate automatically
5. Processing completes in 1-3 minutes for most videos

What happens during processing:

• Speech-to-text transcription (99% accuracy)
• Speaker identification (if multiple speakers)
• Topic detection and clustering
• Key point extraction
• Chapter boundary detection
• Timestamp synchronization

Step 3: Review AI-Generated Summary

After processing completes:

1. Click your video to open it
2. Navigate to the Summary tab
3. AI-generated summary appears with key points
4. Review the content structure and highlights

Summary structure includes:

• Opening overview (context and main topic)
• Key points organized by theme
• Important quotes and highlights
• Conclusion or takeaways
• Action items (for meetings/presentations)

Summary length: Typically 10-20% of original transcript length

Step 4: Explore Timestamped Chapters

Navigate to the Chapters tab to see:

1. AI-generated chapter titles describing each section
2. Timestamp for each chapter (clickable)
3. Brief description of chapter content
4. Screenshots from each chapter (optional)

Using chapters:

• Click any chapter title to jump to that moment
• Expand chapters to see detailed descriptions
• Use search to find specific topics
• Toggle timestamps on/off for cleaner view

Chapter generation:

• AI detects topic changes and speaker transitions
• Typically creates 3-15 chapters depending on video length
• Chapters are evenly distributed across content
• Each chapter has descriptive title and summary

Step 5: Search and Navigate

Use the search function to find specific content:

1. Click the search bar in Summary or Chapters tab
2. Type your keyword or phrase
3. Matching sections highlight automatically
4. Click any result to jump to that timestamp

Search capabilities:

• Full-text search across summary and chapters
• Finds mentions in transcript segments
• Highlights matching keywords
• Shows context around matches

Step 6: Ask AI Questions About the Video

Use AI chat to interact with the content:

1. Navigate to the Chat tab (if available)
2. Ask questions about the video content
3. AI responds based on the transcript
4. Get specific information without watching the entire video

Example questions:

• “What were the main action items discussed?”
• “Summarize the Q&A section”
• “What did they say about budget?”
• “List all the features mentioned”

Editing and Customizing Summaries

Troubleshooting Common Issues

”Summary is too brief”

Causes:

• Short video content
• Repetitive content without key points
• Poor audio quality affecting transcription

Solutions:

1. Ensure video is fully transcribed (check Transcript tab)
2. For short videos, summary may be proportionally brief
3. Use AI chat to ask for more detailed summary
4. Create custom document using Templates tab

”Summary missed key information”

Causes:

• Technical jargon not recognized
• Off-topic discussion
• Poor speaker clarity

Solutions:

1. Review transcript for accuracy first
2. Edit transcript to correct technical terms
3. Use Templates to generate new summary with corrections
4. Manually add missing points to summary

”Chapters are not well organized”

Causes:

• Unstructured content (casual conversation)
• Frequent topic changes
• Short video (fewer than 5 minutes)

Solutions:

1. AI works best with structured content
2. For unstructured videos, use summary instead of chapters
3. Manually note important timestamps
4. Consider recording with clearer topic transitions in future

”Processing taking too long”

Causes:

• Very long video (2+ hours)
• High server load
• Large file size

Solutions:

1. Typical processing: 1 minute per 10 minutes of video
2. Videos over 2 hours may take 15-30 minutes
