VideoTwin Finder
Native macOS SwiftUI app for exact and similarity-based video deduplication.
Find duplicate and near-duplicate videos on your Mac fast, review them side by side, and clean up storage with confidence.
VideoTwin Finder helps identify exact duplicates and visually similar videos across your folders in a native macOS workflow. It combines fast duplicate prefiltering with frame-based similarity analysis, duration-aware candidate pruning, perceptual hash support, and cache reuse for faster rescans.
The app is designed for real libraries where files may have been re-encoded, renamed, trimmed slightly, mirrored, or exported more than once.
What it does
- Scan one or more folders for duplicate and similar videos.
- Detect exact duplicates using file size and SHA256 hashing.
- Compare visually similar videos using sampled grayscale frames.
- Review grouped matches with thumbnails and detailed file metadata.
- Inspect resolution, frame rate, codec, bitrate, modified date, and match context.
- Reveal files in Finder, open them, or move unwanted copies to Trash.
- Reuse cached scan data for unchanged files to speed up repeat scans.
VideoTwin Finder is built specifically for macOS using SwiftUI, AppKit, AVFoundation, CoreGraphics, and CryptoKit. It stays within the native Apple stack and focuses on practical review workflows.
