colorgrade.video puts a grading suite in a browser tab. Simple mode gives Auto colour plus roughly 300 original looks drawn live on your footage, with an intensity slider and skin-tone protection. Pro mode adds Colour wheels, curves, HSL, secondaries with qualifiers and masks, colour matching to a reference image, and Waveform, Parade, Vectorscope and Histogram scopes. Log and HDR footage converts to Rec.709 and your own .cube LUTs import. Free, no sign-up, no watermark.
Proper colour grading has meant installing DaVinci Resolve or paying for an editor, which is a lot for someone who wants to fix or style one clip. colorgrade.video was built to bring real grading tools and scopes to the browser, free, with footage processed on the device.
