"Ghosting" is exactly what you described with "warpy lines that make it look like you were shooting in a heat wave" and is caused by slow shutterspeeds.
A general rule of thumb in video is to use shutterspeeds about twice as high as the framerate your shooting. With 24 and 25 fps it's a shutterspeed of 50, with 30 fps it's 60 and so on...
If you're going higher you risk strobing, if you're going lower your risking ghosting
