Frequently asked questions

Do I need to shoot in Apple Log?

No. Lutter grades ordinary SDR and HDR video as well as supported Apple Log and Apple Log 2 footage. A LUT (Look-Up Table) can transform or style color; choose the input format the LUT was designed for.

Which devices are supported?

Lutter requires iOS 17.2 or later or iPadOS 17.2 or later. You can import and grade existing footage on either iPhone or iPad. Apple Log recording and some HDR or advanced workflows require compatible source footage and hardware; you do not need a Log-capable camera to grade ordinary video.

Does Lutter upload my videos anywhere?

No. Lutter processes every video entirely on your device. Video processing happens on your iPhone or iPad. Your footage is not uploaded for processing. Read the full privacy policy for details.

How do I import a custom .cube LUT?

Tap LUTs → Import in the editor and pick your .cube file from Files (iCloud Drive, Dropbox, local). Lutter supports standard 17³, 33³, and 65³ cube grids. Imported LUTs work on the Free tier — no Pro required.

What is free, and what does Pro unlock?

Color wheels, tone curves, scopes, basic color adjustments, custom .cube import, and up to three LUT / Grade cards are free. You can export a single video up to 4K in SDR / 8-bit H.264 or HEVC without a watermark when no Pro effects are active.

Pro is a one-time purchase, with no subscription. It unlocks premium LUTs, Cinema Looks, additional cards, advanced color tools, film effects, stabilization, Skin Tone Fix, batch video export, supported LUT export, ProRes, and 10-bit delivery including compatible HDR.

You can preview Pro editing tools before buying. Exporting with Pro effects requires Pro or removing those effects. The price shown in the app and Apple's purchase confirmation applies; offers and local prices may vary.

Why might I see a different Pro price?

Offers and local prices can vary. All Pro offers unlock the same Pro benefits with one purchase and no subscription. The price shown in the app and Apple's purchase confirmation applies. If you already own Pro, use Restore Purchases with the Apple ID that bought it instead of buying again.

How do I get a refund?

All purchases are processed by Apple. Visit reportaproblem.apple.com, sign in with your Apple ID, find the Lutter purchase, and request a refund. We can't issue refunds directly, but we're happy to help diagnose anything that went wrong — email us first.

I think I found a bug. How should I report it?

Please email support@lutter.app with: (1) device model and iOS or iPadOS version, (2) Lutter version (Settings → About), and (3) what you were doing when the bug happened.

I bought Pro but it says I haven't. How do I restore?

Tap Settings → Restore Purchases in the app. Make sure you're signed into the same Apple ID you used to buy Pro. If that doesn't work, email us — Apple sometimes takes a few minutes to propagate purchases.

Why does my export look different on my computer or social media?

Displays and services can handle HDR, color profiles, and tone mapping differently. For sharing to a service that does not support HDR reliably, choose SDR / Rec.709 and 8-bit H.264 or HEVC. Pro also supports compatible 10-bit HLG or PQ HDR delivery. If the result still looks wrong, send us your source profile, LUT input format, and export settings so we can investigate.

Can I use Lutter for client work / commercial use?

Yes. Lutter is sold under a personal non-transferable license, but the videos you grade with it are yours and you can use them commercially. Some bundled LUTs originate from third-party sources licensed under Creative Commons CC0; you can redistribute the resulting graded video freely. See the Terms of Use for details.
