Convert Video to Slides
Recorded lectures, webinars, training sessions, and conference talks contain valuable visual content trapped inside video files. Extracting the slides β along with the presenter's spoken content β gives you a reusable, editable presentation that's searchable, printable, and easy to share.
How AI Extracts Slides from Video
The AI uses multiple techniques:
1. Scene Detection
The AI analyzes frame-by-frame changes to detect when a new slide appears. It captures:
- Slide transitions β when the visual content changes significantly
- Partial updates β when bullet points are added incrementally
- Screen shares β presentation slides shown during screen recordings
2. OCR (Optical Character Recognition)
Text visible in the video frames is extracted using OCR:
- Slide titles and body text
- Code snippets (for tech talks)
- Diagram labels
- On-screen annotations
3. Speech-to-Text
The audio track is transcribed and:
- Aligned with corresponding slides
- Added as speaker notes in the PowerPoint output
- Used to generate slide summaries
Step-by-Step Guide
Method 1: Direct Video Upload
- Go to Video to Slides
- Upload your video (
.mp4,.webm,.mov,.avi) - The AI processes the video:
- Detects slide changes β captures key frames
- Runs OCR β extracts text from each frame
- Transcribes audio β creates speaker notes
- Review the generated slides
- Download as
.pptx
Method 2: YouTube URL
- Go to YouTube to Slides
- Paste the YouTube video URL
- The AI downloads and processes the video automatically
- Same output: slides with extracted text and speaker notes

Optimizing Video Quality for Extraction
Recording Tips
For future recordings, optimize for slide extraction:
- Record at 1080p minimum β Higher resolution = better OCR
- Use high contrast slides β Dark text on light background
- Minimize presenter overlay β Full-screen slide view when possible
- Stable frame rate β 30fps is sufficient
- Clear audio β Good microphone for better transcription
- Pause between slides β 2-second pause helps detection
Handling Poor Quality Videos
For low-resolution or noisy videos:
- The AI uses enhanced OCR with noise reduction
- Speaker notes may have lower accuracy
- Consider uploading the original slides if available and using the video just for speaker notes
Advanced Features
Slide Deduplication
When presenters go back and forth between slides, the AI:
- Detects duplicate frames
- Keeps only unique slides
- Orders them logically
Incremental Slide Building
For slides that build up content (animations):
- The AI captures the final state of each slide
- Or optionally captures each step as a separate slide
- You choose which approach in the settings
Multi-Speaker Detection
For panel discussions or multi-presenter videos:
- The AI identifies different speakers
- Tags speaker notes with speaker attribution
- Can create section breaks between speakers
Frequently Asked Questions
Can it extract slides from Zoom recordings?
Yes. Zoom's MP4 recordings (including gallery view and speaker view) work well. The AI focuses on the shared screen content and extracts slides from it.
What about videos without visible slides?
For talking-head videos without slides, the AI creates slides from the speech content β summarizing key points into visual slides. It works similarly to the Text to Slides tool.
Does it work with videos in languages other than English?
Yes. OCR and speech recognition support Arabic, French, Spanish, German, Turkish, Japanese, and more.
Can I extract only specific parts of a video?
Currently, the full video is processed. After extraction, you can delete unwanted slides from the generated deck.
