Machine Gun Spitball Effect Breakdown

Directing & VFX

This shot from a short film required a rather extensive visual effects treatment. The boy in the shot had taped a series of pens together to form a spitball machine with which he strafes an unfortunate would-be bully. This particular shot required time-ramping in post, 2D tracking for masks, 3D tracking for matchamation of the spitball machine and the resultant paths the individual spitballs trace through space.

Fume FX was used to give the smoke effects, and a subtle image warp helped give a sense of weight to the spitballs exiting the barrels.
