It´s quite easy.. Because I´m not a creator (or author) of that animation and videos..
Get three videos to display them.. There were no time and conditions to get the original (huge) animation..
Than I am not quite following you.
Resolume Arena is a media server, right? It is sold like a media server.
So, why we are discussing about playing one video vs. 3 videos in one time synced?
Am I able to play only one video in one time with Resolume, and two or more can´t be played synced?? So I don´t need it, because I can do the same thing just with the quadro card with mosaic and a Windows player, or to play it on some laptop and do a slices in some processor..
Than Arena isn´t a mediaserver, but still just a software for VJs, or a player with some features..
Edit: This is nothing against Resolume, but it is almost same, like there will be some issue with warping, to tell me, that I can warp it on a beamer (yeah, it is possible on some of them), or export the animations or footages already curved
