Exporting Motion Path keyframe data
I’m working on a project between dance, video and architecture. I’m using Trapcode particular to draw a path/curve that’s following someone in the video. To do this I use a light as an emitter and keyframe it’s position throughout the video.
The result is a curve that AE/Particular draws according to my “Light” position keyframes.
Here’s the question: how do I export the (x,y,z) data of position of the light each fifth frame, so that I have all those positions in an array as follow example:
(630,7 , 287,3 , -355,6)
(634,5 , 256,7 , -356,9)
(637,8 , 245,4 , -358,7)
…And so on.
Can I do this using expressions?
(I could do it manually, but it would be such a lot of work… Really.)
If I have them in an array I can use them in Rhino to go 3D.
I’m using adobe CS 3 on macbook pro.Thanks so much for every lead that I can get…

You could do it with a script. Another possibility would be to add this expression:
value
And then convert the expression to keyframes (Animation > Keyframe Assistant > Convert Expression to Keyframes). Then just select the property, Edit > Copy, and paste into a spreadsheet or text editor. Then you just need to figure out how to thin the data.
