Concussed/drunk vision in After Effects
/Introduction
In TV and television when someone is concussed, faint or drunk they sometimes have a view from the actors point of view which is blurred and shaky. In this tutorial it shows you how to use a simple expression to create this type of effect.
Steps
- Open After Effects 
- Import your concussed/faint footage in to a new composition 
- Duplicate the footage (ctrl + d / cmd + d) 
- Change top layer footage’s transparency (t key) to about 40% 
- We want the top layer footage to move on the x axis to create the effect. To do this we are going to use an expression, Alt + click on the positions (p key) stopwatch and insert the following: 
 w = wiggle(3,200);
 [w[0], value[1]]
- Add a motion tile effect to the top footage (search for it effects and presets) and increase ‘output width’ to repeat edges that are revealed.
