The white balance in a video reflects the lighting conditions under which the video was shot. Adjusting the white balance can effectively improve the ambient color of your video.
Adjust the white balance in your clip by changing the Temperature and Tint properties. You can use the eye-dropper to click an area in the footage that is white or neutral in color. The white balanace automatically gets adjusted. Alternatively, you can use the slider controls to fine-tune the temperature and tint values until you achieve the desired color balance.
