I am flying with a Mavic Pro2 with the Hasselblad camera. The thing I like about the Mavic is it is small, easy to maneuver, stable and the camera lens and sensor are great. I also have a Phantom 3 Advanced, and I find it a bit harder to use, and less stable. So if you are still using a Phantom, you might think of upgrading.
Creating an aerial video is not hard. The FloorPlanOnline production department will take your video clips and make a custom video. All we need is raw footage to help us tell the story. You can check out the FPO Air doc on some key moves you should have for each video. I also have compiled a few videos from YouTube that explain some of the modes that help make it easier. The Mavic has more but the Phantoms also have various flight modes. Just search YouTube for your specific model and modes.
At the end of the day, we just need some stable, well exposed clips to put in a video. These are generally 2-5 second clips. All you need to do is fly and record and FPO Production will extract the clips out of the footage. Just follow the shots in the FPO Air doc.
