BASECUT FREE LOG-TO-REC.709 LUT PACK
====================================
Version 1.0 (2026-10-06)  |  https://basecut.app/guides/apple-log-lut

WHAT THIS IS
Nine 33-point 3D LUTs (.cube) that convert log footage to Rec.709 video.
They are a clean starting point for grading, not a finished look.

Things to know before you pick one:
- Apple Log means the original Apple Log profile. Apple Log 2 is not covered.
- DJI D-Log is not D-Log M. Footage shot in D-Log M needs a different curve.
- GoPro Protune Flat is a flat profile, not a true log curve. This LUT uses
  the Protune curve and Rec.709 primaries (there is no wide gamut to convert).
- Fujifilm F-Log (original) is not F-Log2. Use this only on F-Log2 footage.

WHAT EACH LUT DOES (the same steps for every camera)
1. Decodes the camera's log curve to scene-linear light.
2. Converts the camera's color gamut to Rec.709 primaries.
3. Places 18% grey at the same level for every camera, so shots from
   different cameras start at the same exposure and contrast.
4. Applies one shared soft highlight roll-off, so bright areas do not
   hard-clip.
5. Encodes with the Rec.709 transfer function (BT.709 OETF). 18% grey lands
   at about 0.41 (41 IRE).
Output is a standard Rec.709 video signal for a Rec.709 / BT.1886 display.

SET EXPOSURE FIRST
A LUT cannot fix a badly exposed clip. Expose your log profile the way the
camera maker recommends, apply the LUT, then adjust white balance and
exposure by eye and on the scopes. These LUTs are not a camera-match grade
and add no creative look.

HOW TO USE
DaVinci Resolve
  1. Project Settings > Color Management > Lookup Tables > Open LUT Folder.
     (Mac: /Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT
      Windows: C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT)
  2. Copy the .cube files in, then restart Resolve or click Update Lists.
  3. On the Color page, right-click a node > LUT > pick the matching file.
     Set the timeline to Rec.709 Gamma 2.4 to match.
Adobe Premiere Pro
  1. Open the Lumetri Color panel on the clip.
  2. Basic Correction > Input LUT > Browse, and pick the .cube file.
  Newer Premiere versions can also auto-detect some log formats. If yours
  already converts the clip correctly, do not stack one of these on top.
Final Cut Pro
  1. Effects browser: apply the Custom LUT effect to the clip.
  2. In the effect's controls, choose the .cube file.
  Final Cut Pro already has built-in Camera LUTs for Apple Log and several
  other profiles. If the clip is already converted, do not stack a second LUT.
Other editors
  Any editor that loads .cube LUTs as an input or technical LUT will work.
