You need to do a whole lot more work to get videos of a generally acceptable quality.
These miniature cameras all suffer from a ultra fast shutter which creates the weird prop effects. I've got through several of them.
One can alleviate the artefacts a bit with a neutral density filter, which slows down the shutter, but really one needs to use a camera with a manual shutter control, like the semi-pro camcorders have.
I am now using a Canon Legria G10 and with a 1/120 (or slower) shutter the result is really good. But obviously this costs more money.
Vibration is also an issue. It blurs the image. One needs to make an anti-vibration mount. People doing this seriously use special vibration absorbing bushes like
these to make up a camera mount. They are cheap enough but hard to get in the UK; I have ordered some from the USA.
Here are some suction mounts.
