The Short Answer
A LUT is only as good as its match with your footage. Before you buy one for iPhone 17 Pro Max video, check five things: what input it expects, what file format it ships in, which editors it supports, whether it shows real before and after examples, and whether the seller is honest about what it can do.
1. What Input Does It Expect?
This is the question that matters most. iPhone footage can be Apple Log or standard Rec.709, and those are very different starting points. A LUT built for one will look wrong on the other. Look for a product page that says plainly which it supports, and a setup guide that explains it. If the page never mentions Apple Log, be careful.
The ARRiPhone LUT is made for iPhone footage shot in Apple Log or Rec.709. If you are not sure why the input matters, read ARRI LogC vs Apple Log.
2. Is It a .cube File?
The .cube format is the most widely supported LUT format. It works in DaVinci Resolve, Premiere Pro and Final Cut Pro, and most mobile editors can import it. A LUT in an unusual format may limit where you can use it.
3. Does It Work in Your Editor?
Check the product page for the apps you use. Some LUTs also include setup instructions, which saves time if you are new to LUTs. The ARRiPhone LUT lists DaVinci Resolve, Final Cut Pro, Premiere Pro, CapCut and LumaFusion, and includes a setup guide.
4. Are There Real Before and After Examples?
Pictures sell LUTs, so look for clips or stills from real footage, not just mock-ups. A good sign is a mix of lighting conditions: daylight, indoor light and night. Be wary of examples that only show one perfect scene.
5. Is the Seller Honest?
A LUT is a look. It cannot give an iPhone the sensor, lens or dynamic range of a cinema camera. A trustworthy seller says so. Be skeptical of promises like "make your phone look exactly like a cinema camera" or "one click, no work". Good results still depend on exposure, white balance and taste.

Questions people ask
Do I need a different LUT for Apple Log and Rec.709 iPhone footage?
Often yes, because the starting point is different. Check what the LUT says it expects. The ARRiPhone LUT is made to work with both Apple Log and Rec.709 iPhone footage.
What file format should an iPhone LUT be?
The .cube format is the most widely supported and works in DaVinci Resolve, Premiere Pro, Final Cut Pro and most mobile editors.
Will a LUT make my iPhone look like a cinema camera?
No. A LUT changes color and contrast, not the sensor, lens or dynamic range. It can move your footage toward a cinematic look when the shot is well exposed.
