Cube To Xmp Converter -
You cannot import a .cube into Lightroom, but you can emulate it.
You are a photographer who edits in Lightroom. You find a stunning "Cinematic LUT" pack online, but it only comes in .cube format (for video editors). Without a converter, you cannot use that $50 LUT pack in Lightroom. Converting it to XMP allows you to apply video color grades to your still photography.

| "Profile not found" in Lightroom | XMP is corrupted or wrong folder. | Re-convert. Ensure file extension is .xmp, not .xmp.txt. |
| Image looks completely black | Cube LUT expects Log video (e.g., Sony S-Log3) as input. | Apply an "Input Transform" in your converter to flatten the image first. |
| Colors are neon/crazy oversaturated | Color space mismatch (Rec.2020 to sRGB). | In the converter, manually set Input Color Space to "Rec.709" and Output to "Adobe RGB." |

| The LUT is too strong | This is a feature! | In Lightroom, after applying the XMP, use the "Amount" slider at the top of the Basic panel to fade the effect to 20-30%. |
