About LumaFlow: HDR to SDR converter
Shot in HDR on your iPhone, but the footage looks washed out, grey, or oversaturated the moment you drop it into an editor? LumaFlow fixes that in one tap. LumaFlow converts iPhone HDR video (HLG / Dolby Vision) into clean, standard SDR (Rec.709) that looks right everywhere: Premiere, Final Cut, DaVinci Resolve, CapCut, YouTube, or any timeline. Highlights hold, skin tones stay natural, and colors look the way you saw them. And now it does more than tone mapping: HDR to SDR. One tap conversion any editor understands. Compress. Shrink clips to a target size, percentage, or quality, or cap the resolution. Convert format. Switch between MP4, MOV, and M4V. Batch everything. Fix, compress, and convert multiple clips at once, and chain steps in a single pass. Why LumaFlow: Fast processing, right on your device. No uploads, no waiting. Works completely offline. Your videos never leave your iPhone. Dead simple. Drop clips, tap, save to Photos. Keeps quality intact. Never inflates or bloats your files. Perfect for editors, creators, and anyone who needs iPhone video that just works in their tools. Free to try. Upgrade to Pro for unlimited conversions: monthly, annual, or a single Lifetime purchase. One purchase works across iPhone, iPad, and Mac. Questions or feedback? We'd love to hear from you. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
