Crank vs ColourTemp

The professional technical standard for high-speed cinematography. Crank is the definitive technical utility for camera departments, designed by industry professionals for DITs, ACs, and Cinematographers. Built for high-pressure environments, Crank provides absolute precision for off-speed frame rates, exposure compensation, and technical camera data—all in a sleek, offline-capable interface. Whether you are matching motion blur between project frame rates or modeling complex ND stacks on a remote location, Crank ensures your technical decisions are made with absolute confidence. KEY FEATURES: 1. ADVANCED OFF-SPEED ANALYTICS Eliminate technical uncertainty when shooting off-speed. Quickly determine the relationship between Sensor FPS and Project FPS. Multiples Mode: Instantly view common speed ratios (2x, 3x, 4x, etc.). Reverse Lookup: Find the exact sensor frame rate needed to hit a specific speed target. 2. PRECISION EXPOSURE ENGINE Master your light with dedicated exposure modeling tailored for cinematography. Exposure Compensation: Determine T-stop adjustments when changing frame rates or shutter angles. ND Filter Stepper: Manage neutral density stacks with ease, converting between Optical Density, ND numbers, and Stop reductions. Visual Shutter Angle: Use the interactive visualizer to understand effective motion blur geometry and shutter speed relationships. 3. PROFESSIONAL CAMERA DATABASE A comprehensive, searchable library of professional camera specifications at your fingertips. Detailed Specs: Access sensor dimensions, base ISOs, mount types, and dynamic range. Format & Frame Rates: Check maximum frame rates across different codecs (ARRIRAW, ProRes) and resolutions. Supported Models: Includes up-to-date data for ARRI (Alexa 35, Mini LF, etc.) and other industry-standard systems. 4. ON-SET UTILITY SUITE Setup Card Export: Generate and share technical camera setup cards with your department via a single tap. Job Presets: Save recurring project settings (Base FPS, ISO, Shutter) for instant recall on different shows. Offline First: No signal? No problem. All core technical features and database tools work entirely offline. WHY CRANK? Crank is a specialized workflow utility. By focusing on the specific needs of the camera department, we’ve removed the clutter found in generic apps to give you the fastest, most reliable path to the technical data you need on set. Built by Emin Atilgan GBCT and Joe Dibble DIT.

ColourTemp is a colour temperature and flicker detection tool built for working videographers, DPs, cinematographers and gaffers. Point the camera at any light source for an instant Kelvin reading. Switch to flicker mode to detect mains-frequency flicker before it becomes a post problem. COLOUR TEMPERATURE Measure light from 2500K candlelight to 9900K open sky. White balance is locked to a fixed 5600K reference for consistent, repeatable readings across a shoot. Readings are close approximations — a fast, practical guide for the set, not a replacement for a calibrated colorimeter. FLICKER DETECTION Uses 240fps camera sampling and FFT analysis to detect 50Hz and 60Hz mains flicker and harmonics. Also flags PWM dimming on LED fixtures that conventional measurement misses. BANDING RISK CALCULATOR Set your project frame rate and shutter speed. ColourTemp calculates instantly whether your current combination will produce banding — and can snap to a safe setting automatically. FREEZE & COMPARE Pause a reading to lock a reference. Adjust frame rate and shutter speed while the measurement stays frozen — ideal for comparing multiple fixtures or matching practical lamps. CALIBRATION Point at a known 5600K reference and take a five-second calibrated reading. The app stores a custom offset for your device and shooting conditions, improving consistency across a whole production. Built by a working DP — because practical fixtures don't ask permission, and bad light costs money in post. No account. No data collected. Everything runs on your device. Available as an annual subscription or one-off lifetime purchase. Pricing and terms are shown at first launch. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
