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.
Man, I’ve worked with digital chroma key masking for 20 years, but it never even occurred to me that they would have done it with physical bags and the like on television. That is so cool. I feel like a kid all over again watching this.
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.
I remember seeing this segment as a kid - thought it was so cool finding out how this worked. The panel van in the footage at the start was pretty cool too!

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.
It's amazing to think that just three decades later any bozo with a green screen, a smartphone and some editing software can do the same thing at home.
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: ruclips.net/video/UkNgWXpnyuI/видео.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
And to think that the quality & technology is so much better these days, that you can produce blue/green screen videos on your cell phone with just an app. I took video production classes back in the mid-80's, and it is still amazing how much easier it is to do these days.
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.
Stumbled on this during another Curiosity RUclips wormhole and made me wonder Deane and Rob, being in Adelaide, did either of you have anything to do with the special effects demonstration at the Investigator Science Centre in Adelaide? The whole thing was based on chroma key, and you got to take home a video of your family doing all the cool blue-screen things. I still have mine.
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
Deane on Hey Hey it's Saturday was the best segment of that show. I loved the optical illusion with small and big people which I think they had/have at Questacon in Canberra. Why? Well I'm glad you asked!
I remember the BBC used to use bluescreen a great deal for Doctor Who, but they hadn't perfected the technique yet and the shimmering outlines were awful and very distracting! Between the outlines and the wobbly sets it was quite hard to suspend your disbelief for the length of each episode! Looking back, it was quite ridiculous but we tuned in almost religiously every Saturday nonetheless.
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.
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.
that's so valuable! simply priceless. the way he educates his audience. especially the last part. it might be disguised as just an innocent homework style of task. but it's essentially trying to make people/kids watch out for scams. don't believe anything you see. only bummer, it turned out not to be like overly successful, lol (which is surely not their fault .. they tried the best possible but some that prefer to stick their heads into sand among us are simply beyond help).
It's so refreshing to see a science show for kids that don't feel the need to turn things into a loud party and repeat the same basic concept 200 times. Bravo.
I was so lucky to go to Para Vista high school in Adelaide ,where our media teacher worked for channel 7 before becoming a teacher. We had a complete studio set up at the high school,even beyond 2000 came and do a epesode there
Good expalination but @ 1:17 "camera does not see blue" is incorrect the black box in control room replaces the blue from camera 3 with all the colours from camera 1
When I think of Bill Nye I think of a show that focused on entertainment first and information and education second. Remember when History and Discovery were about History and science and not ancient aliens and auctions?
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: ruclips.net/video/UkNgWXpnyuI/видео.html
This trick is used all the time on Twitch nowadays, except some streamers purposefully wear bits of the keyed color, or use the accent color of their chair as a key color, causing their hat or their chair to have holes in them.
Whenever I get my mind blown in the first 30 seconds of an episode of youtube I tell my cellmate to pour cold water on my head to cool down my brain. Now that successive inmates have requested to be moved to another cell, I am usually alone. I worry for the welfare of my head brains.
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.
@@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.

That's great and everything, I just have one question. How does it work? Yes, yes I know the principle that he's just described, but how do they get the camera to ignore that particular shade of blue? .. I'm guessing some kind of computery wizardry going on inside a processor somewhere but it would be cool to learn.
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
Way back in the seventies, my great uncle told me, believe almost nothing of what you hear, and only half of what you can see. Of course he was talking about government's and the media, radio and television.
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 ruclips.net/user/curiosityshow
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.
Hmm, a key. They use a key. I remember this guy, Ace Baker (who pretended to shoot himself on live radio if im not mistaken, but anyways) He produced a video about Keys and how they might have been used to construct certain videos. Hmm.
I wish this show made it into my life when I was a kid, ive watched a lot of episodes, even on topics that i am already knowledgeable of, but theyre both fun and interesting.
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.
Either one is used today. Green works good with digital production but can spill on edges and blonde hair. It works good for daytime or light scenes. Blue requires more sophisticated lighting and works good for night or dark scenes. Blue is a common clothing colour (jeans) so green seems more appropriate to use for a streamer.
I LOVE how dense the information is. They don't waste time repeating things unnecessarily, and they speak quickly. What a great show. Wish this was in the States when I was growing up.
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

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.
somehow this is really interesting even tho pretty much everyone knows this these days
That's how they do the space station !

Back when it was blue and not green.
Either one is used today. Green works good with digital production but can spill on edges and blonde hair. It works good for daytime or light scenes. Blue requires more sophisticated lighting and works good for night or dark scenes. Blue is a common clothing colour (jeans) so green seems more appropriate to use for a streamer.

No, but believing is magic
