It would help if it wasn't a video of a video... LOL.

Why not load the actual video from the camera to youtube?

It does sound loud and probably valve train related but it's hard to tell.

 

the video shows nothin but the engine. the sound is whats important

 

sounds like valve tap.... the way its speeds up and you rev

 

Defiantly sounds like valve train to me. Take your valve cover off and look for anything bent or abnormal.

 

yep, im thinking a valve tap too.
