The mobile app has no custom LUT import — there's no button to find. Grade your frame in Luttie, send the graded file to your phone in one scan, and CapCut never needs to read a .cube. On desktop, where CapCut does import LUTs, export the .cube instead.
Exports .cube — no plugin or extension to install.
Building the look
The three things worth knowing before you blame the LUT.
Mobile has no LUT import at all
This trips up a lot of people, because plenty of guides claim otherwise. There is no import button in the filters panel on iOS or Android — custom LUTs are desktop-only, so on a phone the grade has to be baked into the file before CapCut sees it.
Grade to taste before you send
Because the look is baked in, there's no intensity slider afterwards. Dial the strength in Luttie first — a look built on a bright reference frame usually reads too strong over phone footage.
Grade before you add text and effects
Applying colour after overlays tints the graphics too. Get the footage right first, then add titles in CapCut.
No. The CapCut mobile app has no custom LUT import on iOS or Android, despite what many guides claim. Custom .cube import is a desktop-only feature, found under Adjustments → LUT → Import.
Grade the photo or video frame in Luttie first, then send the graded file to your phone and import that into CapCut. The look is already baked into the file, so CapCut's missing LUT import stops mattering.
Close, but not identical. CapCut's built-in filters are presets baked into the app and shared by every user. A LUT is a portable colour-mapping file you make yourself, so your grade is yours and works in other editors too.
No, on either platform. CapCut applies LUTs on desktop but has never been able to save a grade as a .cube file — that needs a separate tool.
Grade in the browser, send the finished file to your phone, cut with the look already there.
Free to grade and export watermarked previews. Pro — from $21.99/mo or a one-time $109 lifetime licence — unlocks clean LUT export, and Luttie is fine to use for commercial and client work.
