Colour grade video online, with LUTs and scopes
A real grade, not a filter slider: lift, gamma and gain wheels, curves, one-colour corrections and your own LUTs, with scopes that show exactly what you are doing.
Three steps, a couple of minutes
Add your clip
Drop a video on the timeline and select it. Shot in S-Log3, V-Log, Canon Log 3, LogC3 or D-Log? Choose it and the picture is brought to normal video first.
Balance, then shape
Auto colour sets white balance and levels as a first pass. Then use the wheels, curves and a colour range to change only the sky or only skin.
Add a look and finish
Pick a film look or import a .cube LUT, set its strength, add grain, halation and a vignette. Copy the grade to other clips or match them to a reference shot.
Why use CutLuma for this
Scopes that tell the truth
Luma waveform, RGB parade, vectorscope with the skin-tone line and histogram, so you grade by measurement and not by a bright laptop screen.
The same in the export
The grade runs on your graphics card in one pass, and the exported file gets exactly the frame you saw in the preview.
Your LUTs
Import 1D and 3D .cube files and apply them with a strength slider on top of your own grade.
Questions? Answers.
Is it free?
Yes. Colour grading, scopes, looks and LUT import are free on every plan.
Does it work with 10-bit log footage?
Log footage is converted and graded, but the browser hands over 8-bit frames, so a very hard stretch can band. Light dithering and grain help.
Can I match two shots?
Yes. Shot match moves a clip’s levels and colour balance onto a reference clip; adjust from there.
Which browsers?
Chrome, Edge and other browsers with WebGL2. Without it the grade is skipped and the panel says so.
