This is what happens when you record a plane's propellers with a cell phone.

The Phone's Camera uses an algorithm which reads the picture information line by line. Since the plane's propeller rotates very fast, the camera's line-by-line method is way too slow to capture a correct picture of the propeller.

Phone can only capture so many frames per second, and the propellers are spinning at a certain RPM, just a weird optical illusion as a result of that.
You ever wonder why driving on the highway at night it looks like the wheels on the vehicle beside you are spinning backwards? The street lamps in most of North America run at 60Hz meaning those lights are actually blinking on and off 60 times per second creating a strobe effect; blinking so fast your eyes and brain can't even pick up on it. Once your wheels spin above a certain speed, it will appear like they are going backwards!

And that is why I shake my head at videos of UFO´s captured on video, you can´t thrust video, use your own eyes and see.

#17 totally right about the lights, in fact if you try to record a tv or a street lamp you will notice black lines on the screen same as the propeller (by tv i do mean an old crt tv as modern lcd and plasma some times have 100-200hz and you wont see it so much)
Kinda reminds me of the strobe lights on the old record players.

The rolling shutter effect is the result of the cheaper CMOS sensors used in mobile phones and consumer level HD cameras. It's also the cause of jello/jelly lens, where the subject is relatively static but the camera itself is moving a lot. Where the camera pans up, the footage appears squashed, where it pans down, it appears stretched, and where it pans right or left, it tilts in the direction of the pan. All video cameras suffer from the effect described by #17. This effect is particular to those cameras where the top of the video frame was not captured at the exact same instant as the bottom, which is what happens with older (and in my opinion, better) CCD sensor cameras.

My guess is that it is a Bombardier (Dash-8) Q-Series airplane, in which the propeller is by Dowty.
