this. in all honesty it would take a TON of time and money to get everything right. and theres a lot of outside variables that can make the platform pretty unstable and unreliable. your are much better off buying a small quad, and learn to fly. get some buddys as well so you can swap out and get shots of each other. its will be sooo much easier, a hell of a lot cheaper, and filming or not, they are a ton of fun to fly.
i started with this, roughly $500 ready to go
and i just finished building this, about $1600 as it stands (waiting for gimbal and fpv gear another $1000)
also as stated above the dji phantom is a phenomenal started platform for aerial videos/photos. i still wouldnt recommend it as a first multirotor but its not bad either, just a bit more expensive to crash.
also, please please please dont call it a drone!!!! any person outside of the hobby who hears drone automatically things military/weapons/spying. call it a quadcopter/hexacopter/octocopter/ect. or just multirotor. just my $0.02
