Better song mayhaps? The song has very weak sync points so it's not an easy song to use in the first place.
You can sync it by grabbing the flow and speed of the song too, or with the lyrics but it's not easy to sync that song, yes.
The vid is pretty nice, most of the replays were actually good, some were not that good. The effects were well placed and the vid was not boring. The only thing that i didn't like was the way of using the freecam, could be better. But it's a nice and entertaining vid
