Color Correct Video Online

Colour controls interact, so the order you use them in matters. A cast tints everything, including the shadows and highlights you are about to judge, so it has to go first. Saturation exaggerates whatever is already there, which means boosting it before the balance is fixed simply makes the cast stronger.

1. Neutral first: remove the cast with Auto colour, Pick white, or Temperature and Tint by hand.
2. Tonal range next: set Blacks and Whites so the darkest and lightest parts of the picture land where they should, then adjust Contrast to taste.
3. Colour intensity third: Vibrance for muted footage, Saturation for an even boost or cut.
4. Single colours after that: the HSL tab changes one band, such as a sky that came out too cyan or grass that looks radioactive.
5. A look last, if you want one: choose it from All looks (L) and set Intensity; it now sits on a neutral base, so it behaves the way its thumbnail suggests.

Each step is visible in Your grade, and Undo (Ctrl/Cmd+Z) walks back through them if one goes too far.

Screens lie. A laptop set to night mode, a phone with True Tone or a monitor in a sunny room all shift how colour looks, and your eyes adapt to a cast within seconds. The scopes measure the pixels themselves, so they give the same answer on any device.

• Waveform plots brightness against horizontal position in the frame. It shows at a glance whether anything is pinned at the very top or bottom of the range.
• Parade splits that plot into red, green and blue. Over something that should be neutral, the three columns ought to reach the same height; if the blue one rides higher, the shot is cool, and if red does, it is warm.
• Vectorscope maps hue as an angle and saturation as distance from the centre. A neutral clip clusters around the middle; a cast pushes the whole cloud off-centre. Its skin tone line marks where human skin of every complexion tends to fall, because skin colour varies mostly in lightness and amount of colour rather than in hue.
• Histogram counts how many pixels sit at each level, which makes clipping and empty ends of the range easy to spot.

Automatic balance relies on two old, reliable ideas. The grey-world idea says that an ordinary scene, averaged together, comes out roughly grey, so any overall tint in the average is probably the light, not the subject. The brightest-areas idea says that the lightest parts of a frame are often white or near-white surfaces lit by the main source. Auto colour blends both estimates, measured on a few frames from your clip, and holds back to 85% of the full correction.

Scenes that fool it

• A frame dominated by one colour, such as a lawn, a swimming pool, a red stage curtain or a sunset sky. The average is not grey, so a full correction would drain the scene of its real colour. Lower the result by hand or start from Pick white on a neutral object.
• Mixed light, such as daylight through a window plus warm lamps indoors. One global balance can only favour one source; pick the one falling on faces.
• Shots where the camera’s own white balance drifted during the take. The correction applies to everything you export, so trim the clip into steady sections and correct each one.

It is measurement and arithmetic, not generative AI: nothing is invented or repainted, and every value it sets appears on the Basic tab where you can see exactly what it did.

Correction moves the colours that were recorded. It cannot restore a channel that was clipped: a face lit by a saturated orange stage light may have no usable red detail left, and pulling the orange out leaves a flat, waxy patch. It also cannot separate two different lights hitting the same subject, because the tool works on the whole frame rather than on drawn regions. Heavily compressed clips, such as video saved from a messaging app, carry little colour information to begin with, so strong corrections show blocks and banding sooner. Gentle moves on a good source file always win.
