Help with 3D tracking stuff

Recommended Posts

Hey Yall,

 

So I have this scene that I am creating in After effects, attatched below a frame from the original footage. So basically I am creating a 3d hud and stuff which I did in After effects, but I would like to put some grass and trees on my computer/desk and make it look like a Jungle. Also, the camera is moving in a half-circle around the computer. How would I go about doing this?

 

Thanks in advance.

You can track the camera in C4D and export the camera to AE.  There are a ton of tutorials on youtube for this kind of workflow.  AE camera tracker would probably do this too....

    Ok. Would it be okay if I tracked through Mocha AE, or do you advise me to do it through Cinema 4D. Also, how am I going to position the grass throughout the scene if they are on different x/y planes?

     

    Thanks

    If you need to move your layers back in Z space (which should be the direction perpendicular to the computer screen) you'll need a 3D camera solve.  If it was 2d (just the screen on one plane for example) you could use Mocha AE (Mocha Pro can do a 3D solve but I don't think Mocha AE can).  Once you have a track and a null that represents the xyz co-ordinate of your HUD (should be positioned in C4D before moving to AE ), you need to make your layers in AE 3D layers and then position them accordingly.  It's probably better and more flexible to do everything in C4D though. You'll get real 3D results instead of the 2.5 3D AE is going to hobble together.  You can then comp your elements in AE afterwards.  If none of this makes sense, check out some 3D tracking tutorials on Youtube or Ciniversity.  It's pretty straight forward.
