What could be causing this noise? It sounds a lot louder than in the video when engine is frozen, like -10F. Goes down significantly once engine is warmed up.

That sounds exactly how mine sounded. I tried the tensioner first and it didn't make any noticeable difference either. I ended up doing the whole timing chain. Pull your valve cover and look at the gears. If they have pointy teeth its time for new ones.
Here is the link to some pictures of mine before and after.

Yes, after i replaced all my gears and guides all the noise is gone. Here are some picks of the lower gears but im not sure they were the cause.
The deflection gear still looked pretty much new and the crank gear wasn't nearly as bad as the cam gears. Since the cam gear have a much larger diameter I would think that any wear on them would make a much larger difference than on the lowers.
