Log footage

Grading flat log footage from Sony, Canon, Nikon, Apple and DJI cameras in Luttie, and building LUTs that expect log input.

Log footage looks flat and grey on purpose: the camera records more dynamic range than a normal video file can show, and it has to be converted before it looks right. Luttie has two ways to do that.

Option 1: the film engine's Source

Open the Film panel, pick a negative, and set Source to your camera's format: Sony S-Log3, Canon C-Log3, Nikon N-Log, Apple Log, Apple Log 2 (iPhone 17 Pro) or DJI D-Log. The engine decodes the log curve and the camera's colour gamut, then develops the image as film. There's no separate conversion step. Grading this way is free.

Option 2: a camera LUT preset

In the Creative panel, the camera categories Pro hold conversion LUTs for DJI D-Log M, Canon C-Log, C-Log 2 and C-Log 3, Sony S-Log2 and S-Log3, Nikon N-Log and Apple Log. Pick the one for your camera, then grade on top in the other panels.

The Apple Log LUTs are built for the original Apple Log. The iPhone 17 Pro can record Apple Log 2, which uses a wider colour gamut, so on that footage use Option 1 with Source set to Apple Log 2.

Use one or the other, not both. A film Source set to log plus a log conversion LUT converts the footage twice, and the result looks harsh and oversaturated.

Building a LUT for log footage

  1. Save a still frame from your footage at full quality, from your editing app or your camera, and load it in Luttie. A screenshot of a video player won't do.
  2. Convert it with one of the options above, then grade.
  3. Export the LUT Pro.

The LUT then expects log input: apply it to the log clips in your editor directly, with no other conversion LUT before it.

Camera LUTs to download

Ready-made conversion LUTs for each camera are on the camera LUTs pages, and the Log-to-Rec.709 reference explains which transform each log profile needs.
