Colour grader

What you can do here

Grade a picture the way a colourist would. Point your camera at something or start the test pattern, then work through lift, gamma and gain, set your contrast against a pivot, push the shadows one way and the highlights the other, and watch the scope respond as you go. Drag across the frame at any point to see what you have actually changed.

Every frame is processed by your own browser's graphics hardware and never leaves your device — there is no server to send it to. No account, no sign-up, no email. When you have a look you like, export it as a .cube file and load it in Resolve, Premiere or Final Cut. The grade is yours.

What a look actually is

A grade is an order of operations, not a filter. Lift moves your black point, gamma bends the midtones without touching either end, and gain scales the whole thing from the top. Contrast pushes values away from a pivot you choose — set that pivot wrong and a shot goes muddy or brittle no matter what else you do. Split-toning tints shadows and highlights independently, weighted by how bright each pixel already is, which is why it reads as colour grading rather than as a colour cast.

Saturation comes after the split tone here, deliberately. Put it before and the tone you just introduced gets desaturated back out again. A LUT, when one is applied, sits last of all — that is where a creative look belongs, on top of a picture that has already been balanced.

About the LUTs on this page

The built-in looks are generated in code — there is no creator behind them and they carry no name.

Your own export is a different thing entirely. It bakes the grade you built from the controls above into a real .cube file that any editor can read — no creator's LUT is ever included in it.
