    How to fix a dark or flat video

    1. Add your videoThe preview shows every change as you make it.
    2. Move the slidersBrightness lifts or lowers the whole picture. Contrast separates light from dark. Color strength goes from grey to vivid.
    3. Check a few momentsScrub to the brightest and the darkest parts of the video. A setting that rescues a dark scene can wash out a bright one.
    4. Apply and downloadThe same adjustment is applied to every frame.

    Getting a good result

    Start with small moves

    A brightness of +0.10 and a contrast of 1.10 is a visible improvement on most indoor footage. Past +0.20 the dark areas turn grey and grainy, because the camera never recorded detail there; brightening only reveals the noise.

    Order matters

    Set brightness until faces look right, then raise contrast a little to bring back depth, then touch color strength last. Skin turns orange quickly above 1.3.

    What it cannot repair

    Blown-out windows and pure black shadows hold no detail to recover. A second light or a seat facing the window fixes those at the source.

    00:40Questions

    Video brightness editor: common questions

    Can I fix only one part of the video?

    The adjustment covers the whole video. Split the video, adjust the part, then join the pieces.

    Why does my brightened video look grainy?

    Dark footage is noisy, and brightening shows the noise. Use a smaller lift.

    Does the preview match the result?

    Closely. The preview is drawn by your browser and the result by our encoder, so expect a slight difference in strong settings.

    How long can the video be?

    Up to 5 minutes and 100 MB.
