Reflex, How much does one of them set you back ?
Evil Panda, you are very close to home. Have you got any video footage of that flight you took photos from ?
How high do they go ?
To fly reliably with that amount of Smoothness you are in the ball park of around
$2000 plus.
The Phantom set ups at $700 odd minus cameras and gimbals arent quite at the level required for getting nice footage
But you can spend north of $8000 on a larger Octocopter - which would give you the ability to fly in more wind, with a dslr or m43 and smoother gimbal action (3 axis stabilisation)
Then you take your video and
Plug in to around 8 grands worth of computer / software technology with years of learning invested.
Also factor in a lot of learning to fly time (crashes and repairs) and build time (how your soldering technique?) and multiply that by your hourly rate.
Sure is fun though!
