# LUTLINE

> LUTLINE is an on-device LUT and film-look video editor for iPhone (iOS 18 or later) by Pekdemir Labs (Yakup Pekdemir, Türkiye), released in 2026. It converts Log footage to Rec.709 with the camera manufacturer's own conversion LUT, applies one of 188 original creative looks or the user's own .cube file, adds film texture, and exports through the same render graph as the preview — up to 4K, H.264 or HEVC, with no account, no ads, no tracking and no cloud upload.

## Key facts

- Category: LUT app / color grading app / Log video editor for iPhone. Video-first; not a photo filter app and not a timeline editor.
- Grading order (fixed, shown as a "Recipe"): Source (Log→Rec.709 conversion) → Adjust (12 tools + RGB curve + vignette) → Look (creative LUT, 0–100 intensity) → Finish (finishing LUT) → Film (grain, bloom, halation, dust & scratches, RGB split).
- Log conversion: 7 brands, 54 cameras, using each manufacturer's published Log-to-Rec.709 table on a 10-bit read path. Apple Log and Apple Log 2 (iPhone 15 Pro and later; 17 Pro for Log 2), DJI D-Log M / D-Log / D-Log2, Sony S-Log3 (S-Gamut3 and S-Gamut3.Cine), Fujifilm F-Log / F-Log2 / F-Log2 C, GoPro GP-Log, Insta360 I-Log / Log, Leica L-Log. Apple Log is detected from the file's colour tags, Sony from recording metadata, DJI D-Log M from the recorder's `_D` file naming and software tag. Any other camera works through an imported conversion .cube.
- Looks: 188 original LUTs in 10 categories (Cinematic, Social, Clean, Daily, Essential, Movies, Dark, Moody, Filmic, Vintage) plus 6 finishing LUTs; live thumbnails rendered from the user's clip; favourites and recents.
- Custom LUTs: .cube import (3D tables of any size up to 65³, and 1D tables), validated before use; creative LUTs in the Looks tab, conversion LUTs as camera profiles in the Source sheet.
- Export: H.264 or HEVC; 720p / 1080p / 4K, never upscaled; source frame rate or 24 / 25 / 30 / 50 / 60 fps by even division; Smaller / Balanced / Higher Quality; audio pass-through or AAC; destinations Photos, Files or share sheet; size estimate, free-space preflight, progress with time estimate, resume after an interrupted read.
- Fidelity: preview and export run one render graph; every stage verified against a CPU reference; the original file is never modified.
- Privacy: media processed on device; no account; no ads; no tracking; optional anonymous purchase-status measurement (RevenueCat, observer mode) in release builds.
- Pricing (US): Free tier — 6 looks, all basic adjustments, Standard / Apple Log / Apple Log 2 sources, watermark-free 1080p export. LUTLINE Pro — $9.99/month, $39.99/year (7-day free trial), $99.99 lifetime — all looks, film tools, curve and vignette, 4K and Higher Quality export, .cube library, manual camera profiles. Purchases through Apple; a network failure never revokes a paid entitlement.
- Requirements: iPhone, iOS 18.0 or later. English interface.
