Epic Video Finder Interface

Why It's Different

Crafted Interface

Flutter-native, Material Design 3. Light and dark themes that switch in a breath — polish isn't optional.

Exhaustive Scan

20+ formats, every nested directory, one sweep. No file left behind, no time wasted.

Multi-Signal Matching

File size, SHA-256, audio fingerprint, visual fingerprint — four layers of certainty before any verdict.

Transparent Analytics

Real-time progress bars, format distributions, interactive charts — every scan tells you exactly what it found.

Structural Speed

Rewritten ground-up in Flutter/Dart. 10× startup, 100× scanning — speed baked into the architecture.

Fully Local

No network calls, no cloud sync, no data leaving your machine. Deletions always go to the Bin.

Pricing

One-time purchase, lifetime access. One license key activates one device at a time.

Frequently Asked Questions

Size Match
Groups files by exact byte size without reading content. The fastest method, ideal for a quick initial scan. However, different files can share the same size, and re-encoded videos will differ in size.
Hash Match
Computes SHA-256 over the entire file, guaranteeing byte-for-byte identical duplicates with 100% accuracy. Slower since it reads the full file, and any modification (resolution change, watermark, cropping, etc.) produces a different hash, making those duplicates undetectable.
Audio Fingerprint Match
Extracts audio fingerprints to identify identical sound content, catching videos re-encoded or converted between formats (e.g. MKV→MP4). Requires an audio track — silent videos won’t match, and different videos sharing the same audio may cause false positives.
Visual Perceptual Match
Analyzes video frames and generates visual fingerprints, detecting duplicates even across resolution changes, watermarks, or minor cropping. Accuracy may decrease for heavily edited clips.
Visual Semantic Match
Uses a local AI model to understand video frame content, finding duplicates that other methods miss. The false-positive risk is the highest — always verify before deleting.
How It Works
Powered by a flagship AI model (Transformer architecture), running entirely on your device. It samples frames from each video and understands what the video is about, not just what the pixels look like.
Detection Scope
Re-edited videos with similar visual content, clips with different encodes, crops, or overlays, and near-duplicates that other methods would miss.
Model Tiers
Three tiers — Fast, Balanced, and Accurate — let you trade speed for precision depending on your needs.
Important
Because this experimental feature works at the meaning level, the false-positive risk is higher — always verify results before deleting.
Plus
Covers most users with file scanning plus Size, Hash, and Audio Fingerprint matching, handling the vast majority of duplicate scenarios.
Pro
Adds Visual Perceptual Match and Visual Semantic Match, designed for videos re-encoded to different formats, resolutions, or with replaced audio tracks.
Local Processing
All scanning and analysis happens on your device — no network calls, no uploads, no tracking.
Folder Access
The app only accesses folders you explicitly authorize.
Safe Deletion
When you delete duplicates, they go to the Trash first, so you can always recover them.
Minimum Version
Epic Video Finder requires macOS 14.0 (Sonoma) or later on an Apple Silicon Mac; Intel Macs are not supported. On older systems the app refuses to launch rather than running with broken features.
Why macOS 14
The bundled detection engines — video hashing, audio fingerprinting, and AI semantic matching — rely on components that need macOS 14 or newer, so the app’s minimum follows the highest of them.
Checking Your Version
Click the Apple menu → About This Mac to see which macOS version you’re running.
Why This Happens
Epic Video Finder is distributed outside the App Store and isn’t notarized by Apple (which requires a paid developer membership), so Gatekeeper blocks the first launch with a warning. The app is still sandboxed and fully offline — the warning is about the missing signature, not about what the app does.
How to Open
Double-click the app once and dismiss the warning, then open System Settings → Privacy & Security, scroll down to the Security section, and click “Open Anyway” next to Epic Video Finder. Confirm once — macOS remembers your choice.
After Updates
Each newly downloaded version carries a fresh quarantine flag, so macOS may ask again after an update — the steps are the same.

Changelog
