I hear the blips too, personally I think it sounds good... if youtube keeps doing that to your vids you could make the video look like an ancient one that comes out of a projecter... you know, the black and white movies with the little blips that look like tears on the screen?
Anyhow, I'm rambling, congrats to the team for the great trailer, the animator did a nice job. If the animation keeps up this amazing smoothness this could easily become famous on youtube.
