Use motion tracking data to generate a path/stroke - how?
on May 13, 2013 at 1:08:28 pm

I've googled the heck out of this and asked more knowledgable colleagues, but continue to draw a blank.

Ive tracked the motion of an object, and and want to generate a stroke along the motion-tracking path, as the object travels. I.e. it travls from A to B and I want to reveal the path of where it has already been.... a bit like hawkeye in tennis!

Now I know I could just draw the path by hand, key-framing it, but as I have a dozen shots to do this to, I' looking for a quicker way, hopefully using the motion-tracking data.

Any help will be greatly appreciated.

That's a darn good question. It can be done somewhat easily in C4d and probably other 3d programs, but I'm not sure about in Ae. Maybe using trapcode 3d stroke and/or echospace? Sorry I couldn't be much help...
