I was watching a video on YouTube today, and I was trying to determine whether or not I thought it was a fake, and one key thing came to mind while watching.

When a video is recorded digitally, on a device such as a smartphone or digital camera, is it possible for static to occur.

I'm talking about the sort of visual static, like on old analogue televisions when there was a lack of signal, or when it was tuned in to an incorrect frequency.

I'm pretty sure that it doesn't, but I thought I'd ask on here, as I'm sure someone is more knowledgeable in this form of technology, and could give me a clearer answer.

Thanks, Tim

[Addition]

When I am talking about static, the type I am talking about is the 'snow' type we used to get on analogue television and sources. I know interference and noise is possible, but I only want to know in the terms of 'Snow'.

I bet it can be possible for digitally recorded video to have a different form of static (in the term noises). Take for example the current Digital ATSC (US digital OTA) broadcast. Though it is not static, it follows under the term, noises in the feed. If the input feed is not getting enough signal into the receiver, there will be too much noise for the receiver to decode, causing pixelation (a form of static, though not exact).

The category of static signal (noises) can also be done in cammera also, due to the effect of things like limited lighting and bad recording.

I'm aware that interference is possible, but I am talking about the 'snow' kind. Is this possible? or does it just cause pixelation and missing pixels?

Recording for scene straight to a digital content, snowy images are not really possible.

Exactly what I thought, thank you.

Yes. It's possible to have static in Digitally Recorded Video. When I was transferring my VHS/Beta/miniDV Tapes to DVD, every imperfection was carried over including static. You can also digitally simulate old school film.

I know it would be transferred in conversion, but what about during filming?

Yes, still possible. During low light situations, most of the time will have visual artifacts/fuzzies/static. Audio static from a bad mic, wireless, &/or wiring. I just tried it =0p...

But would it be the black and white dots that occur during damaged analogue files?

Loss of signal static/snow/sound is usually filtered on most of today's AV equipment. A BLUE SCREEN has replaced the SNOW, and the STATIC SOUND is filtered out. I had to play with the settings to see the SNOW, but couldn't restore the STATIC SOUND.

"Yes, still possible. During low light situations" - That is not static, that is graininess, you get it from any kind of camera during low light situations be it digital or analog, still or video, 3d or 2d.

no its not possible. unless like above where you convert from something like a tape. the static in tape is imperfections in the magnetic strip. in the digital world this will skip like a cd or stop. not cause static. kind of like the difference between a scratch on a cd and a scratch on a vinyl record. but the static in the answer above isn't from damaged digital media but thats what the tape sent to what was recording it and converting it to digital.

Actually, I believe the static to be edited in, I am trying to disprove something to someone, and this would prove that the video was fake. It doesn't look like the sort of thing from conversion. Thanks for the answer though :) Thumbs up

If the process is digital from the beginning, eg video recorded with a DSLR, then you cant get true static (eg which is why it looks really stupid when those ghost hunter style shows showing a digital camera but the footage having static when a "ghost" shows up)

Usually what you will get from digital video is image noise from the image sensor, especially when high ISO's are used.

PS no digital camera can give a completely noise free image as of now, even the $50,000 ones but they come extremely close.

Your example is exactly the type of video I was referring to. One of my friends was worrying about videos of a mythical internet legend, and she sent me a link to this supposed documentary, but I'm just seeing what I can pick out from it.
