LUT → Sony In-Camera LUT Converter

Did your Sony camera reject a LUT or render washed-out colors in S-Log3? Converting a LUT requires more than resizing a grid: creative looks designed for Rec.709 or Panasonic V-Log must be compounded with Sony S-Log3 technical transforms to display properly. This tool handles intelligent color space transformations (baking Rec.709 film looks for S-Log3), resamples to compliant 33³ or 17³ grids, and formats strict Sony hardware headers for FX and Alpha bodies.

Step 1 · Hardware Target & Color Space Pre-Transform

Sony Hardware & Color Space Configuration

Resampling a LUT from 65³ to 33³ only changes the grid size — it does not adapt a LUT designed for Rec.709 into a valid Sony S-Log3 LUT. Specify your source look's origin and your target camera below to bake the correct color pipeline.

Converted LUT Input

For User LUT 1–16. Sony cameras feed imported LUTs their S-Log3 / S-Gamut3.Cine signal, so the converted LUT turns S-Log3 into a Rec.709 picture before your look. Shot in S-Log3 at normal exposure, the camera's picture should match the look on Rec.709 footage.

Compound Color Transform Pipeline:

Sony S-Log3 / S-Gamut3.Cine (Camera) → Technical S-Log3 to Rec.709 → Your Creative Look → Baked 33³ Sony User LUT

Recommended for Film Stocks

Your uploaded LUT was designed for standard Rec.709 video or film emulation (e.g. Kodak 2383, Fuji, Teal & Orange). For the camera, the converter first decodes S-Log3 with Sony's published curve, converts S-Gamut3.Cine to Rec.709 primaries and maps the result to a Rec.709 picture with a soft highlight roll-off, then applies your creative look, and bakes both into a single camera LUT. For Rec.709 footage in an editor, it only resamples the look.

How to use LUT → Sony LUT Converter

Best for: Sony FX3, FX30, A7C II, A7CR, A6700, ZV-E1, and A7S III shooters.

  1. 1Upload any .cube LUT file from DaVinci Resolve, Premiere, or internet packs.
  2. 2Select the source color space (e.g. Rec.709 film look to bake with S-Log3, or native S-Log3).
  3. 3Select your Sony camera model, memory media (SD vs CFexpress), and target grid size (33³ or 17³).
  4. 4Download the sanitized .cube file (up to 63-character name) and copy it to the exact camera path.

Tips

  • Sony cameras freeze or reject LUTs larger than 33³ — this tool automatically resamples 64³ and 65³ grids into compliant dimensions.
  • If your creative LUT was made for standard Rec.709, choose Rec.709 input space: our converter bakes Sony S-Log3 technical conversion into the 33³ LUT.
  • Sony α7 IV does not feature in-camera User LUT import slots — use Gamma Display Assist (Gamma Disp. Assist Typ.) on camera and apply this LUT in post.

FAQ

Where on the memory card should I place the converted file?

For SD cards (on all models including α6700, α7C II, α7CR, ZV-E1, FX3, FX30, α7S III), Sony requires /PRIVATE/SONY/PRO/LUT/. For CFexpress Type A cards (on FX3, FX30, α7S III, α9 III, α1 II), place in /SONY/PRO/LUT/. Note that the file name must be 63 characters or less.

Which source color space should I pick?

If your LUT is a creative look designed for standard Rec.709 video or film emulation (Kodak, Fuji), select Rec.709: the converter prepends S-Log3/S-Gamut3.Cine technical conversion and bakes a compound 33³ LUT. If your LUT was already created for S-Log3, choose S-Gamut3.Cine / S-Log3.
