I made the video above using Adobe After Effects. You can do lots of things with AE, including animation, color correction, and video effects. To create the projectiles my nerf gun fired, I created a solid with a mask and added fractal noise, motion blur, and color vibrance. To create the vortex on the green blast, I reversed the time and moved it before the blast. I think Adobe After Effects is really cool and worth the $20 a month!
