QuickTime / iPhone
What you graded
Real frame from a wedding film. The washed-out version is what clients were actually receiving.
“You grade for hours — then QuickTime, your phone, and Instagram wash it all out. That’s not your grade. That’s color management fighting you.”
“The cause is a single tag — two bytes. Gradelock sets it in one drag: instant, lossless, on any file. Deliver exactly what you made.”
— Kevin Wolf, Escape Velocity
It changes a tag, not pixels — so it's done in under a second, even on a 20 GB+ ProRes master.
No re-encode, ever. Your resolution, bitrate, and grade are untouched. It's mathematically the same file.
Drop a clip on the window — or the Dock icon. Works with .mov and .mp4 straight out of Premiere, Resolve, or Final Cut.
QuickTime, iPhone, Instagram, Safari — they finally agree with what you graded. Deliver with confidence.
Color-managed apps (QuickTime, iPhone, Instagram, Safari) read a color tag in your file and convert the footage to your display. When that tag doesn't match how the file was actually produced, you get the classic washed-out, lifted-black look. Gradelock corrects the tag so no unwanted conversion happens.
No. Gradelock never touches the video data. It rewrites a tiny tag in the file's header — typically two bytes — so it's instant and completely lossless, even on huge ProRes masters.
Standard .mov and .mp4 files (H.264, HEVC, ProRes) exported from Premiere Pro, DaVinci Resolve, Final Cut, and most editors.
