Sometimes, the original look of the inserted video may not work well with the color palette of your presentation. In such situations, you could play around with the brightness and contrast for an inserted video by using the Corrections option. Additionally, you can also completely recolor your inserted video. Further, you can make your full-color video appear as a grayscale video, or even like a duotone video such as blue and grayscale. Do remember that the video Color options work almost similar to the Color options for the pictures.
