Luttie
Your look, as a real .cube file.
Applied with Custom LUT.
Final Cut has read custom LUTs natively since 10.4.9 — no plugin required. What it can't do is build one. Grade a reference frame in Luttie, export a .cube, and drop it on a clip.
Exports .cube — no plugin or extension to install.

- 4Use the Mix slider to dial the strength back
Building the look
- 1Import a still, or export a frame from your Final Cut timeline
- 2Grade it in Luttie until the look is right
- 3Export as a 33-point .cube
- 4Apply Custom LUT on your clips and reuse the preset across the project
What trips people up in Final Cut Pro
The three things worth knowing before you blame the LUT.
Custom LUT and Camera LUT are different things
The Camera LUT setting in the Info inspector handles log conversion for the source footage. Your creative look goes on the separate Custom LUT effect, after it.
Mix is your strength control
The Custom LUT effect's Mix slider is the clean way to run a look at 60%. Don't bake a weaker version of the LUT unless you want it permanently that way.
Save it as a preset once
Once the effect is set up on one clip, save it to the Effects browser so the whole project is one drag rather than a file picker every time.
Custom LUTs in Final Cut Pro
Do I need a plugin to use custom LUTs in Final Cut Pro?
No. Final Cut Pro has included a Custom LUT effect since version 10.4.9, which loads any standard .cube file. Third-party LUT plugins exist but aren't necessary.
Can Final Cut Pro export a LUT?
No. Final Cut applies LUTs and saves effect presets, but it has no way to render a grade out as a .cube file. Luttie does that part in the browser, and the result works in Final Cut like any other LUT.
Why does my LUT look wrong on log footage?
Check the clip's Camera LUT setting in the Info inspector first. If the log conversion isn't applied, a creative LUT lands on a flat image and overcorrects.
Final Cut applies LUTs. Luttie builds them.
Grade a frame in the browser and export a .cube for the Custom LUT effect.
Free to grade and export watermarked previews. Pro — from $11.99/mo or a one-time $68.99 lifetime licence — unlocks clean LUT export, and Luttie is fine to use for commercial and client work.
