What is making this noise in my Evo IX ? (Video Inside)

I think its a pulley. But im not a mechanic so I wouldn't know. Can anyone give me some opinions on what it is? If I rev the engine I don't hear it getting louder or anything like that. And it sounds like its coming from the side of the engine near the pulleys and belts.

Well let me add this:
When it just starts up, there is no noise at all. When it starts to get warmer that's when the noise appears. Im in the Wisconsin area so its cold outside always around here.

I just sprayed WD40 on the pulley that is on the alternator. The noise goes away completely for maybe 10 minutes. Now it only makes a slight quieter version of the noise. So IDK about the whole timing belt suggestion.

get under the car with a breaker bar and loosen the serp belt tensioner. Then just check that it is lined up on the teeth/grooves correctly. Not sure how old yours is but if its been awhile then just get a gates belt replacement for $20-30 from rockauto and swap it out. Kind of a PITA but takes like 20 minutes.
if thats not it then it is most likely the timing belt. How many miles on your current timing belt? did the tensioner get replaced when you last changed it?

Just simply remove your serpentine belt. Start the car. Is the noise still there?? if so its in the timing area. If not, its obviously an accessory. You can take a long screw driver or pry bar and put it on each pulley bolt, the other end to your ear, and see which one makes the loudest noise. Its either the pulley itself, or whatever the pulley is driving (like the alternator like you stated) Or it can be just as simple as a stretched or worn out serpentine belt. In that case replace it. Hope that helps.
