You wont trust anything that you see on TV after you watch this !

It appears that they can change a TV scene to look different in a blip !

to what now seems almost impossible to tell whats real or made up or altered.

Could they also use it for news media or even a 9/11 type incident..that could create other illusions...

Did they have this on 9/11..I wonder..

Apparently, it's a video for people that think that TV shows and movies are all filmed on location and didn't know about chroma key, an 80 years old technique.

What is the amazing thing is that today still so many believe anything they are told to believe and yet will not question when there are flaws in a story. Mind control?

[ArMaP]

Mind control?

Ignorance.
Most (if not all) people I know that do not question what they are told do it because they never learned that questioning things is the best way of learning, and that learning is the best way of getting a better life.

Very insightful and well said.

I am aware that TV can be make things seem to create changes in many a thing that is on film and maybe used to think at least back in the earlier days that they had pre edited it..

but upon looking at the video... it seems to make changes appear almost live..

I also suspect surely this  is much more advanced than what you refer to (Chroma Key)...which I had not come across such a term..

So are you suggesting its nothing new and just still using the old type technology ?

That's because of the way the video is edited. Does anyone recognise the images that appear on the video? They look more like images from movies or TV series than live transmissions.

There's no need for a more advanced technique if they just want to replace the background. In fact, by using it more than once they can replace more than one part of the background in a scene, so the background can be made from several different backgrounds.

How the background is made also makes a difference, as you can have images from a real background or from a computer generated background. The children's TV show Lazy Town used backgrounds created in a system based on Unreal Engine 3, a system that anyone can download and use for themselves. In the case of Lazy Town their system moved the 3D computer generated scene in the same way the cameras were moving, so the computer generated scene followed the movements of the actors and everything looked like one scene.

So are you suggesting its nothing new and just still using the old type technology ?

Yes, maybe with the help of some newer technology, but the system is 80 years old, while the basic idea (superimposition of images) is as old as photography, which means something like 180 years old.

I do watch some TV, I only saw parts of some episodes of Lazy Town while changing channels, I know about this because I have been an user of Unreal Engine for some years, although I never did anything worth mentioning with it.

what characteristics of lazy town alerted your attention to the usage of the unreal engine within the show.. faint smatterings of blood maybe?

Nothing, I read about it on a site about Unreal Engine.

When we watch normal TV if there is such a thing..as long as its not live TV ,  I/we may assume that they had already usually arranged what they show from one scene to another and it appears to change in a flash...but often we see a scene maybe go from what appears as one location to another..

but with the video I posted , it shows egs of how the background can change with maybe a few egs while focusing say on the main foreground or a or certain  person/s and that may appear live..

There was an eg where you see a person say standing on a ledge at the Grand Canyon... in good weather and next thing they change it to a similar scene maybe on a Snow capped mountain...but the persons appearance and actions at the time are identical...

that to me seemed a bit unique..and very cleverly done and its hard to tell what may or may not be the real scene..

that's assuming one of them may had been the real original one..

That's because of the way the video is edited. Does anyone recognise the images that appear on the video? They look more like images from movies or TV series than live transmissions.

I was not aware of Lazy Town..but I can imagine that there are such programs that can create and change scenes ..but I was initially referring to that sort of thing being more like a new type of technology to achieve such scenes.... rather than a 80 yr old Chroma key methods that you referred to..

That's more what I was thinking.. maybe old tech with new more modern computer technology to achieve better quality scenes.

That's the result of editing, and how they can get several points of view with just one camera: first they film one point of view, then the other, etc., etc., and at the end they join the several pieces in the order they want. That's one of the reasons why filming a simple scene can take hours or days. One of the best examples is the shower scene from Psycho, a scene with 77 different angles, lasts 3 minutes and took 6 days to film.
Many things can be done in editing, usually to give the viewer an idea of faster action.

but with the video I posted , it shows egs of how the background can change with maybe a few egs while focusing say on the main foreground or a or certain  person/s and that may appear live..

Appear live? Why?

There was an eg where you see a person say standing on a ledge at the Grand Canyon... in good weather and next thing they change it to a similar scene maybe on a Snow capped mountain...but the persons appearance and actions at the time are identical...

Sure  they are identical, there's only one scene, the one filmed with the green background, the background is added in post-production, like most special effects.

that to me seemed a bit unique..and very cleverly done and its hard to tell what may or may not be the real scene..

That's the whole idea, make the scene look real without having to fly all the people needed to the top of a mountain.

that's assuming one of them may had been the real original one..

The one with the green background, that's how chroma key works.

I was not aware of Lazy Town..but I can imagine that there are such programs that can create and change scenes ..but I was initially referring to that sort of thing being more like a new type of technology to achieve such scenes.... rather than a 80 yr old Chroma key methods that you referred to..

As I said, there's no need for new technology, that's why they use chroma key: it works, it's cheap and fast.

PS: in many cases, the sound is also added in post-production, as it's easier to record the sound in a controlled environment.
