Helle people,

I will start a exciting motion tracking assignment in a week.

The footage will be shot by a Drone. We will film a lar= ge open field where
there eventually be 3D buildings.

So some motion tracking and some 3D work.=

Would the 3D camera tracker inside of AE be suffi= cient or should I try an other one?

And do I= need tracker markers on the field?

I am n= ew at this and every tip is very welcome.

C= heers,
Anthony
