tutorials I used to educate me on my way to building my motion graphics video are;

http://www.videocopilot.net/tutorials/soul_removal/ in an attempt to show the smoke travelling through the body to the lungs, combined with the expressions controls found in http://www.videocopilot.net/tutorials/3d_stroke_effect/.

e.g. x=thisComp.layer("particle source").transform.position[0]-thisComp.width/2;

"x=/thisComp.width

postion [0] (represents the x value or the null object)
possition [1] is the Y
and position [2] is z"

this was to get the particles to fallow the null object. (expression writted by andrew Krammer from video copilot.)

i fallowed http://www.videocopilot.net/tutorial/advanced_time_freeze/ but unfortunately could not complete it which was extremely frustrating.

http://www.videocopilot.net/tutorials/advanced_car_hit/ for the car hit at the beginning of the video.

http://www.videocopilot.net/tutorials/stabilize_shaky_footage/ i used inspiration from this video frequently to patch up mistakes in the raw footage etc. but much of this didn't make the final cut.

http://www.videocopilot.net/tutorials/earth_zoom/ i was going to use to zoom out after the glass field effect but it didnt really fit well in the end. so i didn't bother completing it using my own maps.
