Steps
  1. Open After Effects
  2. Import your concussed/faint footage in to a new composition
  3. Duplicate the footage (ctrl + d / cmd + d)
  4. Change top layer footage’s transparency (t key) to about 40%
  5. 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]]
  6. 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.
