Use 3d camera tracker for motion tracking bullet impacts?
Not sure how to explain this, but here goes. I’m working on a short film with lots of gun fire. One scene take place as the characters run up a dirt hill. I have dirt explosions from video copilot which work great as the bullet impacts. Before CS6 I simply tracked motion for each of the bullet impacts, then parented the impact to a null containing the motion tracking.
This is fine, but is there a way to “batch” or “auto” motion track a short clip?. The 3D Camera Tracker “looks” like it does this, but is there a way to add 2d layers to the 3d points?
Thanks for any thoughts,
Stephen

I think I found the answer here: https://blog.vincentlaforet.com/2012/06/25/tutorial-after-effects-cs6-3d-camera-tracker/ Not exactly what I’m trying to do, but gives a good overview of layers instead of just 3d text.

See this very recent COW thread on linking a 2D layer/point to a 3D layer’s position.
For your specific case, you can leave the dirt explosions as 2D although I think it’ll look better if it was made into a 3D layer and then switching on its auto-orient to camera setting.
