One recepie would be:
For the strobe : Right-click the event and in properties set the undersample rate to less than 1.
For the delay/trail: Make a copy on the track below, then offset it a few frames. Reduce the opacity of the top layer.
For the grain: Sony Film Grain FX
Flashes: Sony Film Effects flicker, or add manually on track above with white generated media. Adjust duration, opacity, and fade duration to taste.
Gamma, saturation, color balance, etc: Color Corrector.
