PowerPoint 2011 allows you make limited changes to your inserted movie clips. In a previous tutorial, we have already explored how you can correct the brightness and contrast for an inserted movie by using the Corrections option. Additionally, you can also completely recolor your inserted movie — for example, you can make your full color movie appear grayscale, or even like a duo-toned movie combining grayscale with any one color such as blue, green, etc. Do remember that the movie Recolor options work almost similarly to Picture Recolor options.
