Stabilized by onboard Zenmuse gimbal and default Warp Stabilizer settings. Shot on cloudy day…was just a test shot. Exported a low quality. My first with the new gimbal. Seem good enough for tracking? GoPro Hero 3+.

As Chris mentions, drone footage can produce motion blur (or undesirable camera motion). First you will probably want to stabilize/smooth your footage.

Most likely markers are not needed for aerial footage and most of the 3D trackers will be able to handle basic moves.

Since this is your first 3D project, I would recommend relatively simple moves. You can run into issues with full 360 rotations, etc.

Lastly, the 3D camera solver module found in mocha AE v3 & mocha Pro v3 was designed as an alternative to feature based 3D trackers and excels on out of focus or blurred footage. It does not "replace" Syntheyes or PFtrack for feature depth, but may be an easier to learn workflow for newer users.

There is a 15 day trial to help you test it out and here are some tutorials: http://www.imagineersystems.com/videos?tagFilter=3D+Camera+Solve+Module&sortBy=Newest

Best,

My experience with the built in 3d tracker in AE has been very mixed.

Using it on some hand held footage just to test it out it has worked ok good. But each time i wanted to use it on real projects it has failed to give me acceptable results, and have gone back to Syntheyes, that tracks way faster and more accurate, and the camera generated is much closer to the real camera move.

So my advice would be to try the built in first, but do have a backup plan to either purchase another 3dtracker (maybe the multi versatile Mocha Pro with the camera tracker would be better than standard AE even?) and learn the basics of that or hire a guy/girl with access to one to do the track for you.

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 large 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 sufficient or should I try an other one?

And do I need tracker markers on the field?

I am new at this and every tip is very welcome.

Cheers,
Anthony
