Extract slide decks from video content
_{macOS / Linux / Windows}

---

Drop a video file (or paste a URL), pick a similarity threshold, and get a clean set of slides as PNG frames or a single PDF. Frames are compared using per-channel RGB histogram intersection, so only visually distinct slides are kept.

Features

• Smart frame detection - RGB histogram fingerprinting filters out duplicate/similar frames
• Real-time export - PNG frames are written to disk as they're found, not after the full video is processed
• Remote video support - Paste a YouTube or direct URL; yt-dlp downloads it automatically
• PDF export - Flatten kept frames into a single multi-page PDF
• Timestamp overlay - Optional HH:MM:SS burn-in on each slide (built-in pixel font, no dependencies)
• Time range filtering - Process only a slice of the video with start/end timestamps
• Cross-platform - Native desktop app for macOS (Apple Silicon + Intel), Linux, and Windows

Install

Grab the latest build from Releases:

Platform	File
macOS (Apple Silicon)	video2ppt_*_aarch64.dmg
macOS (Intel)	video2ppt_*_x64.dmg
Windows	video2ppt_*_x64-setup.exe
Linux (Debian/Ubuntu)	video2ppt_*_amd64.deb
Linux (Fedora/RHEL)	video2ppt_*_x86_64.rpm
Linux (AppImage)	video2ppt_*_amd64.AppImage

macOS note: The app is not signed yet. After installing, run:

sudo xattr -dr com.apple.quarantine /Applications/video2ppt.app

Prerequisites

ffmpeg and ffprobe must be on your PATH:

# macOS
brew install ffmpeg

# Ubuntu/Debian
sudo apt install ffmpeg

# Windows (scoop)
scoop install ffmpeg

How it works

1. Probe - ffprobe reads the video's duration and resolution
2. Sample - ffmpeg decodes the video at a configurable FPS into a temp directory
3. Compare - Each frame is fingerprinted (per-channel RGB histogram) and compared against the last kept slide
4. Filter - Frames below the similarity threshold are kept as unique slides
5. Export - Kept frames are saved as PNGs (real-time) or combined into a PDF
