LutRec

LutRec — Turn Your iPad into a Professional Real-Time LUT External Recording Monitor

On set, how the picture looks shouldn't have to wait until post-production to be revealed. LutRec transforms your iPad/iPhone into a professional-grade real-time color grading external recorder: connect a UVC camera (such as the Sony A7C II), apply LUT color grading in real time, and see exactly what you get. You can record or capture the graded result directly, eliminating tedious post-production work.

Real-Time LUT Grading Preview Powered by Metal + Core Image hardware acceleration, the preview runs smoothly without frame drops. Both the working and output color spaces are unified to Rec.709, delivering professional color management and reliable color accuracy.

Full .cube LUT Compatibility Import .cube LUT files with a single tap, supporting 1D/3D LUTs. Oversized LUTs are automatically downsampled, ensuring stable compatibility with mainstream color grading files.

Camera Log Pre-Restoration A two-stage professional workflow designed for Log footage such as S-Log3: first use a restoration LUT to convert flat footage back to Rec.709, then layer a stylistic LUT on top — all in one step.

Adjustable LUT Intensity Real-time blending from 0–100% opacity lets you fine-tune while you watch, finding the perfect look for your shot.

Recording / Photo / Live Photo During video recording, LUTs are burned into the footage in real time with efficient HEVC encoding. Photo and Live Photo capture are supported, with results saved directly to the system album.

Stabilization & Multi-Lens Toggle stabilization on or off with one tap. Freely switch between front, telephoto, main, ultra-wide, and external cameras to suit various shooting setups.

Flexible Audio Input Supports the iPad's built-in microphone as well as external UAC audio devices, so you can choose the recording setup that fits your needs.

Custom Watermark Edit watermark text freely and overlay it with one tap, giving your finished work built-in copyright identification.

iPhone Remote Control for iPad Bonjour automatically discovers devices on the same local network, letting you control iPad shooting from your iPhone: start/stop recording, take photos, capture Live Photos, switch LUTs, toggle stabilization, and change lenses — a one-person crew can work just as smoothly.

Minimalist Professional Interface Full-screen, distraction-free preview with large, touch-friendly buttons — anyone can pick it up and shoot on set.
