Does the Note 8 rear camera filter infared light or can it take infared light and convert it to a image within a video? What is the known electromagnetic range of the rear camera? Does it only filter visible light and convert it to image?

Short answer: Yes it does.

Almost all digital cameras have an IR filter installed.

Both CMOS and CCD sensors are sensitive to IR. IR affects image quality so sensor manufacturers install an IR filter on the sensor.

Thanks!

So why do people say you can see IR from a TV remote when you view it with your cell phone?

I've not seen that. I'll have to give it a try.

The reason I am asking is because I took some video, short video, like 4-5 seconds and I didn't see a human like form while taking the video but it appears clearly in the video. It has a lot color. Brown, grey belt, bright illuminated head with facial profile. I want to know what IR conversion would lok like digitally. Would all these colors appear? I think someone edited my video and I am looking for answers.

I honestly don't have any answers as to how that happened.

I have taken IR photos with my Canon DSLR, but I an IR filter on my lens and had to aim and focus it before putting on the filter.

I just tried the IR remote experiment in a dark room and didn't see anything.

Could you indicate where? I'm not seeing anything.

I just posted three photos of it. It looks real as you and me. That is what is so puzzling. It has a brown coat, black belt, white face. It is the focus of the screenshot. People keep looking for shadows or translucent forms. This is not that.

Thanks! If IR wouldn't be converted to color this could possible be a video edit. Do you know anything about codec information?

This is what IR images look like. This is after processing in an image editor.

IR wouldn't be in color.

The reason I am asking about codec information is because when I play the video and look at the video when it is playing, the codec information shows unknown, unknown, while the EXIF shows AAC, and H.264. Could someone edit the EXIF info?

Yes. EXIF can be changed.

a friend of mine The Happy Scientist (small time celebrity) put the video in video software program and used motion tracking on it. He said the motion tracking wanted to put the object closer than it appears. Does this mean anything in terms of video editing?

You'd have to ask him what software he used. But, yes, you can change perspective post video capture.
