Question on how to create a trajectory in After Effects CS6
on May 6, 2013 at 4:35:35 am

Hello all, I have a question on how you guys think I should go about making an effect.

I've searched everywhere and have been trying several different approaches but first I'll describe the effect I'm trying to achieve.

I have an object being thrown and I want to make a semitransparent dashed trajectory as seen in this extremely crude MS Paint illustration I threw up in a minute or two: http://i.imgur.com/c3Qpr7H.png. I also want it to slowly disappear as the object goes through the trajectory.
The camera is moving as well, and I've already set up a null object tracking motion.

So I tried a few approaches. I tried drawing individual rectangles in a precomp and making a mask for the object that covers the rectangles (which eventually fade away) but that was really ugly and time consuming.

I tried making a line as well, but the fact that the camera moves made it too difficult for my level of ability.

I looked everywhere and couldn't find anything remotely similar to what I'm trying to achieve. Any ideas?

Specs in case they're needed.
Intel i7 3770k@4.7GHz
AMD Radeon HD7850 2GB
16GB 4x4GB 1333MHz DDR3 RAM
2x1TB 7200RPM Caviar Black
Adobe After Effects CS6 (Creative Cloud)

Thanks in advance!

This isn't exactly what you are looking for but if you have particular you might be able to use the process to get the look you are looking for.
