Video [Q] Boot animation is a black screen?!

Running an LS-970. I have a custom boot animation that I made, but when I put it in the /system/media folder, it didn't work! Just showed me a black screen. Not even the boot sound worked (it's stock). When I previewed it with Boot Animations in Rom Toolbox, it worked, but was slow. Any ideas on why it's not working? (I've already checked perms, it's read for all, write for owner, and execute for all.) Here's the link to my bootanimation: www[dot] dropbox[dot] com/s/3h7itrkzs5d6ytl/bootanimation[dot]zip (doesn't let me post links, because I'm new. D: )
