UT Explorer - Professional LUT Management & Preview Engine
https://ulti.media/lut-explorer-v2/

Overview
LUT Explorer is a macOS-native powerhouse for photographers, colorists, and video editors to manage, preview, and apply 3D LUTs (.cube files) with unprecedented speed and precision. It acts as a central hub for exploring vast libraries of color lookup tables, delivering instant visual feedback on both static images and live video sources.

Core Purpose
Tackling LUT fatigue—the challenge of finding the perfect color grade among hundreds of similar files—by providing a high-performance grid of real-time previews. See how any LUT affects your footage before you commit to a final render.

Key Features

🎞️ Advanced Media Support
- Static Images: JPEG, PNG, TIFF, and HEIF (HEIC)
- Live Video Player: AVKit playback for MP4, MOV, and MKV. Play, scrub, and evaluate LUTs while the video is in motion.
- "Apply to This Frame": Capture any frame from a playing video to use as a high-resolution static reference for precise color evaluation across the LUT library

📊 Professional Technical Metadata
- Live Overlays: Glassmorphic overlay with technical specs for the loaded source, including:
- Resolution (e.g., 3840x2160)
- File Size (MB/KB)
- Video Specs: Duration and precise FPS
- Dynamic Icons: Instant visual identification of source type (Photo vs. Video)

🎨 Pre-Processing & Correction
Before applying a LUT, tweak the source material to ensure proper normalization:
- Histogram Equalization: Automatically balance exposure
- Brightness & Contrast: Manual sliders to prepare LOG/flat footage for the LUT
- Real-time Engine: All processing happens asynchronously for a lag-free UI

🔍 Library Maintenance & Scanning
- Deep Disk Scanning: Recursively scans directories or connected drives to build a complete LUT library
- Duplicate Detection: MD5 hashing identifies identical LUTs with different names or locations
- Heart Favorites: Mark LUTs as favorites to keep them at the top of the grid

📦 High-Performance Export
- Image Export: Save color-graded frames as JPEG, PNG, or HEIF
- Video Export (FFmpeg Powered): Robust engine supporting:
- Codecs: H.264 (AVC) and ProRes 422
- Containers: MP4 and QuickTime (MOV)
- Bitrate Control: Up to 100 Mbps for maximum quality

UI/UX Design Philosophy

- Glassmorphism: macOS Big Sur+ aesthetics with umUltraThinBackground and vibrant, semi-transparent elements
- Non-Blocking Architecture: Heavy lifting (FFmpeg processing, disk scanning, frame extraction) runs on background queues to keep the main interface responsive
- Drag & Drop Workflow: Drag LUTs, folders, or media files directly onto the app to load them instantly
