I don't have any video or pictures but usually on the pump bracket there should be an area that has a slot cut out and a bolt there. You loosen the bolts that hold the pump to the bracket just enough so that you can move the pump back and forth and then just move it so the belt is tighter. Then tighten the bolt in the slot and then tighten the other bolts. You want to be able to deflect the belt with your thumb about a half inch to an inch or so on the longest part of the belt. Same principle holds for the alternator and AC belts. After you do it a few times you get a feel for it. You don't want to overtighten it. You can use a pry bar or something to move the part with one hand and then tighten the bolt with the other hand. I like to use a tire iron as it usually works good. Hope that gives you the idea. Check your alternator belt as the bracket there is usually more accessible and you can adjust that as well.
