I modified the speed, removed 0.66 of the .gif frames, added a touch of color that morphs as the animation cycles, and it is now an extremely entertaining boot animation for my 2013 Nexus 7. Additional info. can be found on the XDA forum concerning using .mp4 video files as boot animations in KitKat. Now I need to find the author to see if I can get permission to share this sublime animation.
My username on XDA is simply my name.
