My video is greenish, how do I correct it? I guess automatic white balance was fooled by the background (garden through window), and now the people in the interior (yellowish light) look greenish. Is there a way to correct this white balance gone wrong?
Load your clip on the compositor. Add a Color balance node and move the gamma in the opposite direction of the dominant hue of your scene. If your scene is green you want to make it more magenta.
