I recently saw a tutorial to create a bullet trail effect as seen in the Matrix and other films, using Trapcode Particular. I created the trail with Particular and precomposed it in After Effects, and precomposed my base footage too. I then applied the Displacement Map to my footage layer and selected the source to the Solid with Particular on it. For some reason, when I adjust the horizontal displacement or vertical, it moved my footage up and down instead of the Particular. What did I do wrong? Link to tutorial:
Tut for effect starts around 8:50.
"Why, Mr. Anderson? Why, why, why? Why do you do it? Why get up? Why keep fighting? Do you believe you're fighting for something? For more than your survival? Can you tell me what it is? Do you even know? Is it freedom? Or truth? Perhaps peace? Could it be for love? Illusions, Mr. Anderson. Vagaries of perception. Temporary constructs of a feeble human intellect trying desperately to justify an existence that is without meaning or purpose. And all of them as artificial as the Matrix itself, although only a human mind could invent something as insipid as love. You must be able to see it, Mr. Anderson. You must know it by now. You can't win. It's pointless to keep fighting. Why, Mr. Anderson? Why? Why do you persist?"
