How to Use

Introduction — What is LUTScope?

LUTScope is a macOS app that streamlines the color grading workflow for filmmakers. Browse hundreds of LUTs at a glance, preview them through a 2-stage pipeline of Input LUT (camera Log conversion) and Look LUT (creative grade), and quickly find the best look for your footage.

Key Features

• 2-Stage LUT Pipeline: Input LUT → Look LUT applied in sequence. Separates Log conversion from creative grading
• 20-Slot Comparison: Register LUT combinations in slots A–T and compare at a glance
• 3 Favorite Types + Titling: Combination favorites (red heart + custom title), Input LUT favorites (yellow), Look LUT favorites (yellow)
• Favorite Section: Dedicated sidebar panel for browsing, searching, and quick access to favorites
• 1D / 3D LUT Support: .cube format for both 1D and 3D LUTs (1D is auto-baked to 3D)
• Synced Video Playback: All slots play in real-time sync (±15 s range centered on the selected frame, 30 Hz, loop)
• Metal GPU Rendering: Hardware-accelerated preview
• Anamorphic Desqueeze: 1.0x–2.0x in 7 steps
• LUT Summary Package Export: Bundle LUT files + preview images from favorites or slots
• 8 Languages: Japanese / English / German / French / Spanish / Portuguese / Chinese / System

Subscription (App Store)

LUTScope is offered as a Mac App Store subscription. No license key or activation is required — your access is tied to your Apple ID. Every plan includes a 14-day free trial.

Plans

• Monthly — auto-renewing
• Yearly (recommended) — auto-renewing, cheaper than paying monthly

Both plans start with a 14-day free trial and renew automatically afterward. See the Mac App Store product page for current pricing.

Getting Started

1. Download and launch LUTScope from the Mac App Store
2. Choose Menu bar > LUTScope > Subscription... to open the subscription window
3. Select the monthly or yearly plan
4. Complete the purchase in Apple’s dialog to start your 14-day free trial
5. When the trial ends, it renews automatically unless you cancel

What Works Before Subscribing

You can try most of LUTScope even without an active subscription.

• Available: Importing video and stills, frame extraction, video playback, preset saving, and favorites
• Limited: The LUT Grid and Compare show only the first 10 cells (10 slots). Cells beyond that are blurred, with a “Subscription required” banner

With an active subscription, the full LUT Grid and the 20-slot Compare are fully unlocked.

Restoring Purchases

If you purchased under a different Apple ID or reinstalled the app, use Restore Purchases in the subscription window to restore your access.

Managing & Canceling

1. Manage from Mac App Store > Account > Subscriptions
2. To cancel, turn off auto-renew at least 24 hours before the period ends (otherwise it renews automatically)
