Yeah well noticed. No hanging around, punchy and pacy great programme; would have loved it growing up.

They did have an American version. It was called 321 Contact

When you make education interesting you don't need to hammer it into anyone's head. They watch of their own will and they learn because they want more.

@@ashleyhyne7027 its kinda sad what we have for children

Please let me know other channels like this one😊?

Back when I was a kid, before the digital age, a meteorologist made the mistake of wearing a blue tie. It was hilarious but also a bit frightening to see parts of his chest disappear as he moved around.

Yeah, here's proof. This very popular Australian science show later aired on PBS for American audiences. Critics say that he made science sexy and he became somewhat of a sex symbol. In fact, when his show ended, he had a career as an adult movie performer. Enjoy: kzfaq.info/get/bejne/i9F-mrqJ1dTdpX0.html

yes, you're more likely to listen carefully for this "novelty" part. your brain quickly switches into that, "I've to examine that a little more closely"-mode.

The show was made in Adelaide where we had a slightly different accent to people on the eastern states. They seem to put on a fake accent to try and be more Australian where we don't do that in Adelaide lol

​@@RationalSaneThinkerok I think you need to rewrite that because the curiosity show was never seen as a sexual thing obviously you're talking about the American version but make it clear

anyone can do it now using filters without a green screen with ai

@@TAIR736 Not quite. Those filters aren't quite up to the same level yet.

If they light it properly. Too bad most of them don’t, so their keying moves weirdly when it shouldn’t.

No way man... That's kind of impossible. These new fangled gadgets...

and yet, most still dont know HOW its done :P

all the cars were cool mostly Australain made, some Japanese as well

I just learnt it now.

me too and me too

Many thanks. Curiosity Show featured Dr Rob Morrison and Dr Deane Hutton. A science TV series for children, it was broadcast nationally in Australia (where it was produced in Adelaide) and to 14 countries overseas and dubbed into German for European audiences. It won the Prix Jeunesse International in 1984, the top award in the world for children's TV. Lots more segments at kzfaq.info where archived segments are uploaded every week

I'm an '83 vintage from Victoria. I feel this was on ABC?

I'm just glad that this show existed! I remember it been really interesting, and I'm sure my mother liked it too because I stopped asking her questions for a bit.

If only he could get back to 1982... He'd take state!

Napoleon, you know we can't afford the fun pack! What, do you think money grows on trees in this family? Take it back! And get some Pampers for you and your brother while you're at it.

It was awful because it was the BBC. Other countries got it better :-)

I was about 8 when I first started watching Dr Who and I was terrified.

I think we and everyone around were more accommodating. It helped us enjoy stuff rather than be grouchy about it :)

I remember noticing the shimmering outlines and imperfections of cheaply-done chroma-key decades ago... but thinking back, the imperfections were _less_ blatant back then, when viewed on a _CRT_ TV with its inherent "analog blurriness". Old chroma-key viewed on _modern_ TVs/monitors (pixel-accurate, or very close) probably looks more obvious than it might have been originally.

Deane and I were jointly ticket-holders No. 1 at the investigator, we didn't do that exhibit, but may have advised. When Investigator closed, along with two others bought the assets and formed SciWorld, which is now South Australia's largest mobile science education outfit. I chaired it for 10 years or so - Rob

Curiosity Show was produced at Channel Nine(NWS9) North Adelaide - a suburb of Adelaide, the capital of South Australia. I think the scene was shot in a suburban street near the studio (North Adelaide, Prospect or Walkerville). Deane.

And just at that mid point between stopping and explaining I was in shock, shaking.

Yeah, me too

Lol

I’m sure he was running but running on the spot. 😆

still better than what we had then, and bill's show was for KIDS,mit was ment to be entertaining and informative

Hah ... yeah, I used to be fans of both channels. When I tuned in recently, I didn't recognize them anymore. Same for The "Learning" Channel. There is no longer anything to learn.

America had Professor Julius Sumner Miller. The interesting thing is that although he was American, his media career was mostly in Australia. His very popular Australian show was later shown on PBS to American audiences. Watching it, there's no way to tell that it was an Australian show. In one episode, he even inexplicably used 110V bulbs when Australia has 230V. Critics say that he made science sexy and he became somewhat of a sex symbol. In fact, when his show ended, he had a career as an adult movie performer. Enjoy: kzfaq.info/get/bejne/i9F-mrqJ1dTdpX0.html

Thanks for your kind remarks. Keep sharing the good news about our KZfaq science channel with your friends. kzfaq.info Deane.

Not a hundred percent sure but I think the camera still records the blue background and the black box is the thing that switches the blue out for the other video/picture. All that code is probably to complex to explain in this short video.

The trick is to synchronize the frames between the two cameras. That is the camera will be scanning the top left hand corner at the same time was the other camera. When the blackbox see blue coming from the camera, it will switch to the signal coming from the other camera and "paint" in that colour. Yes, it gets very complicated, very quickly.

@@nikhiljose2503 There would be no code. This was all done using analog.

@@gorillaau Actually, it doesn't need to switch or paint anything. The amplitude modulation of the signal contains the luminance component of the signal. The luminance is the sum of all three of of the RGB sensors in the camera. If you disconnect the blue sensor there will not be any luminance when the camera detects the blue background. You can then simply the mix the two signals together and the background image will be displayed where there is no signal from the blue screen camera. You bias the mixer so that the bluescreen camera signal overrides the the background camera whenever the bluescreen signal is present. This can all basically be done using an operational amplifier. You are correct that the two cameras would need to be synchronized. This could be done by using the blanking interval and color burst oscillators from only one of the cameras.

First, this has been done in three distinct ways. Originally, this would have done using photographic film and double exposures. A blue filter would be placed over the lens of a camera and the bluescreen scene would be filmed. Only portions of the picture containing red or green light would be exposed. You then make a set of positive and negative prints. You film the background scene using the three negative prints as a mask so that the background film is not exposed where the foreground image will be. You can then make a double exposure to with the positive plates to expose the background image where the foreground image is. Back when this video was made, they would have used analog processing with video cameras. Professional cameras have three separate sensors for red, blue, and green light. If you disconnect the blue sensor, then the camera will produce no signal where there is only blue light. By mixing the signals together, this will allow the background signal through when there is no signal from the bluescreen camera. Now if of course, this would be done digitally with software processing each pixel and choosing which source defines each pixel based on the color of the green screen source.

It is probably the one recording him walking around the set.

We don't talk about camera number 2.

Heh heh... you said number 2.

@@89horizon Remember 89horizon, do do the right thing

You can do it with any color. It was true in the 1950s; it's true now.

joh joh So, your saying our American TV is superior with such great shows such as Housewives of New Jersey, Pickers, Pawnstars and Happy Days?

No, he's saying it's shit.

no, i'm saying the "i freakin love science" trend is some of the most inane and ignorant bullshit ive seen in my life and i'd like it to be put down like a rabid dog.

@@johjoh4571 i can say the same about this, and bill is better

Are you saying Bill Nye isn't a fart in the wind? I would say he just certainly is.

What i want to know is how they see what is going on behind them? Do they actually see whats behind them or are they looking at a monitor in front of them to know the relative location of things? You can see he grabs the edge of the leaf and you can see it on the weather forecast when they point, but how do they know the relative location of what is where?

They don't see what's going on. That's why they only make those vague "somewhere around there" gestures in weather forecasts. When doing a movie, you simply film the actor first, and then set up background so it fits.

As for the principle behind it, it's rather simple: camera records 3 color channels - red, green, and blue. Subtract red and green channels from blue (in case of blue screen), and what remains are pixels that should be replaced with the background. In practice it's a bit more complicated, you can have partial transparency, various methods to filter out color spill from edges etc, but that's the basic principle

Thanks. Curiosity Show was a national science program for children featuring Dr Rob Morrison and Dr Deane Hutton. It was made in Adelaide, South Australia and screened nationally from 1972 - 1990 in Australia as well as in Europe, Asia and Australasia (14 countries). So that children could repeat the demonstrations, Rob and Deane would use everyday materials around the home that most children could find easily (eg old tins). In 1984 Curiosity Show won the Prix Jeunesse International, the world's top award for children's TV programs. Rob and Deane are steadily uploading segments at kzfaq.info

This segment would be early-mid 80s I’m guessing

It fits, anytime people are involved. Consider how often we all lie to ourselves.

Nah M8

nigga wut

No, but believing is magic

You can use different background colors, that's where the common term "green screen" comes from. The different colors have some advantages and disadvantages. Technically chroma keying is just the compositing method. It doesn't tell you anything about the color used as a background.

I'm sorry, but did you just say "Oh (wo)man?" It's almost too difficult to express how unbelievably stupid that is.
