Found Grade

iPhone HDR (HLG) LUTs for SDR video

The three iPhone 17 Pro HDR clips we probed were tagged HLG with BT.2020 primaries in 10-bit HEVC.[1] Each Found Grade HLG file converts that signal to Rec. 709 SDR and applies one look in a single step.[2]

USD 29, one time. 26 looks, .cube, 33-point grid.

Turn HDR video on

Apple says to go to Settings, Camera, Record Video and make sure HDR Video is turned on.[3] Apple describes these clips as Dolby Vision HDR videos.[4]

We probed three iPhone 17 Pro clips only. Other iPhone models are unverified.

See the looks on real footage

In reading order: the plain conversion, then Dry Sun, Sea Haze and Clean Punch, on licensed Sony S-Log3 footage. The looks are the same on every input once the footage is converted, so this frame stands in for iPhone HDR footage until we have licensed iPhone HDR clips to show.[2][9]

What comes out

The files output SDR Rec. 709.[5] If you deliver HDR, use an HDR grade instead. Apple's own steps for editing these clips use a Wide Gamut HDR Rec. 2020 HLG project in Final Cut Pro.[6]
