Is it Possible to Have Statics in Captured Video?

[geft]

I recently watched Fourth Kind and was left wondering if it's possible to have statics in captured video. From my understanding, static is mostly associated with radio interference when signals interfere with one another on similar frequencies. Since a captured video records visible light (part of the spectrum) into an image sensor, is it actually possible to generate statics?

It depends on what you mean by static.

I think it usually means the crashing noise you get in a radio receiver when there is a lightning strike.
Television is at a much higher frequency than broadcast or short wave radio, and TV signals are usually quite strong, so lightning interference has less effect.

However, you can get interference on the video as viewed on a TV screen and this can be recorded if the signal is being recorded on a VCR.
With Digital TV, it can result in an area of pixellation on the screen.

Interference between two TV signals is also possible with TV. In the Summer months, unusual VHF propagation occurs and TV signals can be viewed at much greater distances than normal. This can result in two TV stations being on the one frequency and they may interfere if they are of similar strength.
