"You're going down" Kingdom Hearts - WIP

[Wandering Utlaga]

This is a 39 second Beta of an amv I'm currently making, with Sony Vegas as my tool. Theres not really much I can say, only that its primarily going to be a lyric synch video.
One thing I would have liked to do is give it a sort of a rumble effect during the songs chorus during the bangs in the music, but theres nothing that really fits what I'm looking for in Sony Vegas' options, as far as I can tell. And my attempts at using keyframes to simulate tend to just look bad.
A thing to point out about the overlay effects: There are two atmospheres throughout the song, in some parts the beat is very stable, and in others the rythm goes mental.

HD option is available, though it doesn't make much difference.

Edit: Never mind, the videos finished.
