1. A method comprising:
obtaining a plurality of polarized digital videos portraying an animation of a foreground subject backlit by a polarized light source;
generating a plurality of corrected polarized digital videos by adjusting intensity values of the plurality of polarized digital videos based on intensity differences across the plurality of polarized digital videos;
generating an alpha matte animation comprising a plurality of alpha mattes from the plurality of corrected polarized digital videos; and
generating a modified digital video by combining the animation of the foreground subject and a replacement background utilizing the alpha matte animation.
