Havn't VCDs been around for like 10 years or so? While most people now have DVD players that will play them now, the format itself is hardly new.
autopr0n is like, down and stuff.
One great thing about VCD is that they work in standard DVD players (NTSC and PAL VCD discs only work in players for the respective formats, of course; a limitation not seen on computers). However, lots of older DVD players can't read CD-R media, because of an incompatibiliity with the DVD laser. Duplicated VCDs on normal CD media work just fine, of course. All DVD players in the market today should work, AFAIK.

VCD's aren't exactly new media. They've been used for years, just mostly in asian markets. Advocating their use now just delays even bigger acceptance of DVD's. Instructional use is one thing that could further drive the DVD format, and even more importantly, set a real demand for recordable DVD's. Sure sticking with CD's might seem good now, but it just hurts the impact of media designed for such video uses.

"Video CDs offer one of the lowest-cost ways of distributing training and instruction. They can be duplicated much faster than VHS videotapes, the media is much cheaper and the postage costs are much cheaper."
can you say "pirated" - thats the main reason VCDs seem to have existed in Asian countries for YEARS now. They get used for anything that can be seen on TV, whether it be movies, TV, karaoke or educational productions. Standalone VCD players are even cheaper than the cost of 2-3 original DVDs. Perhaps with the acceptance of DVD players in western countries that also play VCDs, western educators are finally aware of techniques what asian countries have known and used for years.
How much functionality do the VideoCD 2.0 and 3.0 standards give the developer? Is it still just simple menus and chapters? If anything more than this was needed, then you are back to having to use multimedia CDs in a computer.
Anyone know where I can get "Afterschool Chinese" on VCD?

More access to learning opprotunities? What they need is more of a will to use the opprotunities they have. The unfortunate truth that I have at least witnessed is that most students don't care to learn. those that actualyl do want to learn often find their own means when their opprotunities aren't enough. agreed, some do not, but i believe a far greater number simply do not care.
They go on to say how video is the best way to learn? haha, i don't think so. interaction is needed for real learning. and then, the cd's only hold 70 minutes. what can one really learn in 70 minutes? a lot for some things, but almost nothing for others. a lot of subjects are either a lot of practice (calculus, for example), or just a lot of material (french language). because this offers no interaction (practice/ Q&A sessions), the only application would really be subjects that are volumnous, and those may not fit all in 70 minutes...lots of cd changing is in your future =)
i dunno, it just seems like a waste to me. not that the current education system is anywhere near perfect (indeed, i feel it is far from it), this doesn't seem to me like it would enhance it much. anyone get to watch those science laser disks in science class? interesting pictures and demonstrations, but most of the actual content of the class was drawn on the chalkboard.
Just like how VHS replaced 16mm film (do any teachers know how to thread a reel these days?), the VCD should replace VHS. The reasons why:
VHS tapes get chewed up with use, VCDs don't degrade with repeated playback and if they are damaged, just burn a new copy from your master.
VHS tapes need rewinding, placing wear and tear on capital equipment (VCRs), VCDs don't suffer from this to the same degree.
VCDs can be played by individual students, using a donated computer - no need for those bulky media labs.
VCDs are cheap to mail, so you can trade a bunch of instructional media for less than a dollar.
The only caveat is that the cheapest VHS players are less expensive than the cheapest DVD players (at least, as far as I've seen.)
An additional plus is if this takes off, we can add ANOTHER arena of fair use that uses the "evil" blank CD that the RIAA wants to continue to tax and regulate. The more legit uses we can find for blank CDs, the stronger the argument for banishing the CD tax, and tossing out any notion of regulating recordable media.
At home, I'm spec'ing out a project to convert all analog media that I have (video tapes, audio tapes, etc.) to digital equivalents (VCDs, CDs), and storing copies of them on a big LAN server (MPEGs and MP3s) for my personal library. I expect my tapes to completely degrade in another ten years, so this is one way of safeguarding my investment. On a related topic, does anyone know if there are archived copies of periodical articles, like you can find on microfilm, but on CD?
The author of this article has some good technical points. Yes, VCDs are much easier to deal with on older and less expensive hardware. However, he is neglecting a critical issue : where will one get the content in the first place? Although there are thousands upon thousands of active open source projects out there, only a handful have good free written documentation, much less freely available video tutorials! And while there are a handful of oustanding science and mathematics video series ("The Mechanical Universe", "Cosmos", "By the Numbers"), they are almost always owned by the university or broadcast station which produced them.
So, if you are going to distribute video content, either you are going to have to purchase it, or produce it yourself. It doesn't take much to do a quick-and-dirty video shoot with your vidcam in your bedroom with poor lighting and sound, but to really put together an outstanding series like "The Mechanical Universe" takes a lot of time and effort by a lot of talented people. And if you are going to go to all the bother of mass-distributing your video, it absolutely behooves you to do an outstanding job.
So the question remains... where is all this great video content going to come from?

Science, like Nature, must also be tamed, with a view turned towards its preservation.
"If someone is the best teacher in a country at a particular grade or on a particular subject, their instruction and explanations deserve to be videotaped."
What makes the best teachers the best is because they can respond to my questions. Most of the time, they only need to reword some sentences to turn the light on. With this technology, I cannot ask questions, and therefore, not getting the 'best' from the best.
"They deserve to be compensated for their excellence. And the resulting video ought to be made available to the public for free..."
How are they being compensated?
Good idea though, but like everything, it has limitations.

Over in SE Asia, VCDs are universally used for the sexual education of adults who should know better...
You can read text/image faster than you can listen to a person talk. You can search text faster than you can search a video. You can perform minute fast forwards and rewinds with much greater speed than you can through a video- just move your eye, rather than fiddling with a UI. I could go on for some time with this.
I find it odd that techniques like this aren't used more widely; My school wasn't large or that wealthy, yet they decided to use VCD to teach the course. It seems that VCD isn't widespread just because it takes a little more work to generate a course around it; My French teacher worked hard for a high school level class, but I doubt most do.
The only disadvantage to using video material is the fact that it's video material -- television anyone? It's very easy to stare at a screen and completely zone out, ignoring whatever you're trying to be taught. If not interrupted constantly for questioning and such, VCDs are useless.
You should say "old medium." VCDs have been around for quite some time. The only reason they are new to you is because the MPAA prevented them from being used much in the US. At the same time, VCDs were very popular in Asia (where the piracy of organizations like the MPAA is less palatable) for most of the last decade.
However, I agree that this old medium has become cheaper and more advantageous for teaching than probably any other.
All data is speech. All speech is Free.
The idea is that VCDs are an excellent medium for any instance that require you to distribute video.
I admit that in most cases, video is not the best medium for instruction. However, there are many more applications:
1) Archives of videotaped university lectures at the library [my school had real videotapes and I found this extremely helpful, but they were somewhat jelaously guarded]
2) Sharing video with semi-computer-literate family: Sending out cousin Larry's first piano recital to all the aunts and uncles, mailing a copy of the wedding to all the guests, etc.
3) Distributing underground "cult classic" movies, favorite TV episodes, etc. Demos for independent filmmakers
4) "Handouts" for students in film/advertising class
4) Ticking off the MPAA
5) etc.
I'm sure you can think of more. What kind of geeks are you???
Many people are posting on how DVDs are better than VCDs... while this may be true in some cases, in other ways they're the same thing
DVD = 4.7GB
CD = 650-700MB
(NTSC)
DVD = Mpeg2 video 720x480
VCD = Mpeg2 video 352x240 - 720x480 (xvcd)
Were really talking about storage capacity and video resolution as the main differences here.
My point being that a VCDs with educational content can be produced with DVD video quality, at a cheaper price and still maintain compatibility with standalone DVD players.
Our high school has a program called Real Science where some students volunteer to work on an interacive cd with movies on an area of science. The project is student run and is of fairly high quality.
Lesson One: A VCD is a medium. Multiple VCDs are media.
Lesson Two: New \New\, a. 1. Having existed, or having been made, but a short time; having originated or occured lately. I.e., not VCD.
Got friends?
What is it about VCDs on slashdot that seem so... so... Antiquated? Forgive me for stepping on another deligtfully informing article (ie; wasted space) and say this is a bit behind the times? And what is a VCD going to do that a VCR can't? Sure it's cheap, but unless you're somewhere in Asia, VCDs have gone the way of Betamax. And then you'd actually either have to buy the player or a PC to read it. If you buy the player, that's more out of pocket. if you use the PC, you might as well use CDRs.
Whoohooo... News for nerds, stuff that matters... I'm all over that action, aren't you?
You need a FREE iPod Nano
This argument is as painful now as it was when I was in school. So people are less inclined to learn about the things that you find interesting. Maybe they are involved in other pursuits (sports, dating, etc.)
Blaming students and then suggesting that all educational innovation is futile is ridiculous. What should we use to test student ambition, before making any expenditures on our part?
First of all, didn't VCD come out over 10 years ago? I seem to recall something about CD-I being able to play it (and that being one of it's nifty selling points...or not). That's new?
Second, VCD is a mediUM. When people talk about "New Media" they are speaking of more than one mediUM.
JEEZ. Why do so many people have to do so many bad things to MY language?
So what pray tell should be done with "the dumb kids". Should they be ignored, or do you think some good condescending tough love is in order?
Not to belabor the point, but most people value more in life than grades.
You don't need a computer to play a VCD. All you need is a low-end DVD player, and low-end ones can be found for less than $100 each. Low-end TV sets that are still large enough to be seen by an entire class cost only a little over $100, as well.
So, altogether, I just don't see the point of producing a lot of video at all.
You big goofball, the poster obviously was referring to this nifty ancient decrepit monstrosity that failed miserably.
Hehehe, by the way, I actually do have a few titles on VideoDisc. Need to find a player though :)
Read my stuff.
Everybody's arguing about how VCD is not a new format, but nobody seems to know how old it actually is. Some think it actually came out around the same time as DVD. The fellow who wrote the article thinks it's a new format. One fellow isn't sure, but thinks it might be even older, but isn't quite sure. Egh. Apparently I'm the first who actually bothered to Google it. VCD is fifteen years old. It was created in 1987. Now, was that so difficult? And as a matter of trivia, the compact disc was originally invented with video in mind.
Heck is a place for people who don't believe in Gosh.
...is they actually hook you into the mistaken belief that how well you're doing in Algebra actually somehow matters to you ten years from now.
The enrichment course wasn't graded. You went, you learned, and if you were me, you got bitched out for being too punk rock, even in fourth grade. My problem with public education is that the cirricula is set up in such a fashion that my strengths- creative problem solving, artwork and (through school and the last few years) digital media- never actually applied. Me going to high school (compulsory, thank you) was just about pointless, as the classes played up against my every weakness, with the exception of english and art.
The idea of a grading scale isn't a bad one, it's simply been badly implemented. I brought it up as a point of how things like this are completely and totally misapplied thanks to poorly conceptualized standardization- I'm the sort of guy that wasn't designed for things like math... so as a consequence, through the tension headaches, the cattle prodding, the constant yelling and screaming (my sister didn't have any problems... "You're so smart! Why don't you try harder?!")... I'm stuck with a bit of a negative stigma about things that don't do the least bit of good for the individual being labeled as "educational"... and in the case of the schools, promptly forced down the throats of the undeserving.
I'm one of the few for whom sleeping through English produced A's, moderate effort in Art produced A's and B's.... and hard, raging cramming, studying, nightmares, headaches and endless amounts of rage and frustration produced rarely more than a D+ in math.
I keep drifting off the point... it's late. Basically, the dumb kids will grow up to be dumb adults, the smart kids will grow up to be smart adults, and changing the status quo without implementing eugenics or some sort of Gattica solution doesn't seem likely. Education as it's implemented does nothing more than babysit kids for twelve years while they get a dim idea of what they may want to do for the rest of their life- grades are there to make those that are good at wash-rinse-repeat textbook learning feel good about themselves.
The "dumb kids" have a habit of making life for the smart kids miserable- favoring a Final Solution would be pretty fascist..... I'd like to think that by the time they hit college, the smart kids know that they'll be doing something with their lives, and the ones that tormented them aren't going to amount to much.
Living well is the best revenge, in all honesty.
And- I forgot to add- not very popular with technophiles.
Technophiles are inclined to believe that the more gears and bits you put into a thing, the better it is.
"How dare you suggest your little pocket notebook is better than my PDA? It doesn't even have batteries? Luddite!"
As a programmer for 18 years so far, I have no difficulty ignoring such people.
When the PDA's are significantly better, I will use them. Until then, the pocket notebook is just fine for my needs.
... can use these to get their work out quickly and easily. Since most DVD players can handle this you can just burn a VCD from your computer once you've edited the video.
Better still, you can resize your video to the correct resolution for VCD (352x288 for PAL, IIRC) from the DV capture (at 720x576) and save a huge amount of render time and disk space. Not to mention how much quicker Premiere handles the smaller video files...
I live in Singapore, and VCDs have already been widely used in schools to replace VHS tapes, for quite some time now. If I'm not wrong, VCDs and CD-ROMs have already been in use in schools here since about 5 years ago.
I suspect the reason why the US has not yet widely adopted VCDs is due to the large size of the country, hence the disability to change standards every once in a while, as compared to Asian countries. This is probably also why the handphone standards in US still lag behind Asian countries in general, which normally use the GSM digital standard.
A good development, nonetheless. At least VCDs don't have all the restrictions like region coding or encryption that DVDs suffer from. No RIAA or MPAA or whatever to try to reap profits from the education system.
We (as in the people) can make these now, its not very expensive. Making DVD's is very expensive for the home user. Besides they'll be replacing the DVD format with Blueray in a couple of years, so people might as well be playing with this now.
If Google really cared they would fix Android Chrome to reflow text, instead of discriminating
They don't work in all, but MOST. (Since they are produced in countries where people have droves of VCD's) - Pioneers are generally good, Sonys are bad (they seem to stick to much to some 'standards')
Some players will only play commercial VCDs, and some (especially Sony's) will only work with certain brands of CDR/CDRW. If you have a difficult player, try buying one cdr of several different brands, and see what taste your player has.
Its easy to make one, get the tmpgenc mpg encoder from http://www.tmpgenc.net/ to encode a VCD. and get Nero http://nero.com to burn it on the cd.

There are always some would will start this debate, claiming numbers on their side. But one thing is if what the numbers say, another is what they eyes see.
I've seen commercial VCD's who looked TOTALLY DAMN GREAT! I wouldn't have known it wasn't a DVD if i hadn't been told.
So it might be that technically it was way behind the DVD specs, so what.
Ok, so these VCD's were mastered by pro's of official material, and you are hardly likely to get the same if you fiddle around with a webcam in your living room, but then you wouldn't if you could burn a "real" DVD either.
If Google really cared they would fix Android Chrome to reflow text, instead of discriminating
This is the reason why public schools are chronically underfunded, to provide a steady stream of proletarians that will work to enrich their bosses without becoming rich themselves, and to steadily consume without question the worthless stuff the bourgeois constantly peddle them.
But if the poor start getting educated and rich, the world as we know it will most definitely crumble!!!
Kind of a cool idea though, but with contact needed between the surface and the player (like magnetic media and unlike optical media) it obviously has drawbacks.
My curiosity was piqued by this subject and I got hold of a player and a videodisc recently (anyone who wants to do this should try eBay which has a remarkably comprehensive selection of equipment and movies.) The quality was surprisingly good (except the soundtrack which, played in stereo, had popping noises all the way through it.) I'd describe the video quality as sub-VCD though it was mastered at a time when presumably VHS was sub-VCD too. What's remarkable is that the disc was 20 years old and, for the most part, played presumably almost as well as it did (audio aside) when it came out of the factory. Few picture jumps, fuzz, or anything like that. Try doing that with a 20 year old video tape!
You are not alone. This is not normal. None of this is normal.
Well, maybe you can. Or, more accurately, while you may be able to read faster than you can listen, you may not be able to comprehend. It's all part of the different modes of learning. I have a friend who does not comprehend written words very well. If you talk to her, however, she will understand a great deal. I am the exact opposite. I remember almost everything I read but if you say something to me, then there is no guarantee I will remember it even two minutes later.
You need to move your opening tag up to the beginning of your post. It's not displaying correctly in Netscape 4.7.
I think you're talking about laserdiscs, not VCDs. Laserdiscs require a special player, you can't burn/copy them, and they used to be quite spendy I assume your school got them though some kind of grant or something... I remember someone trying to pawn them off on our school as well. Not quite the same as VideoCDs... which can be used in any classroom that has a PC with a CD-ROM drive, can be copied by any computer with a CD-RW drive, and therefore are more reasonable to use.
That's exactly what I thought..

Not true - at least, not for the Playstation I own. There's a $79 module you can buy that plugs into the back that will allow you to play VCDs though. At the time, I too thought it would work - I think the reason is that some PS discs had MPEG video, but when I tried a VCD it just ignored it.
The PS2 I'm sure will allow you to play VCDs - anyone confirm this?
Careful with their compatibility list. It's not bad, but I found it rather innacurate. Unfortunately, it seemed to err on the optomistic side, too.
EG. My PS2 can't play DVD-R discs of movies properly. Their compatibility list said it could. (I think this is due to people putting in a DVD-R and playing it for a few minutes, so they assume it works fine.) In reality, it usually plays ok until it nears the end of a disc - where it start skipping badly and aborts before the movie ends. They also claimed my Samsung DVD-812 could play MP3 and VCD formats. This seems to have come from its instruction manual, which does state this. Unfortunately, it also clearly states that the DVD-812 won't read any CD-R media. (So tell me, where do you get commercially pressed CD-ROMs full of MP3 music?) I think when most people check a compatibility list on DVD players for MP3 capabilities, they're assuming it'll play them from CD-R type discs.....
I regularly put 45-60 minutes (sometimes a little more) of good-quality video (better than VHS) on an SVCD. It's not as much as the 80 minutes you can get with VCD, but it's better quality. Have a look at this page to get some idea of what I do and what software I use for it.

Yes, someone could re-interpret the story when they make the movie. So what? Someone could do the same by making modifications to the books as well. What good are teachers if they can't choose the most accurate version from hundreds of different performances of Hamlet?
Besides, Shakespeare was a playright, no? His stories were meant to be watched, not read.

Absolutely fascinating. I see no reason why it shouldn't work. I'll have to try it.
That said, control over indexing is critical, and you can index much faster with your eye than with a forward/rewind pair.
But I'll definitely try what you have recommended at some point. I had never heard of that before.
No one was talking about laser discs.
On the other hand, if students were to read NEW books, they would be reading about subjects that interest them, primarily because books written today address the concerns of today. Why teach Shakespear, and not Stephen King? Why teach Moby Dick, and not The Positronic man?
English classes, reading hundreds of years-old books, is like an astronomy class being taught from star charts with The Eath at the center of the universe. Those things do not represent the knowledge, questions, and concerns of people today... They address the concerns of people hudreds of years ago.
If you still don't agree with me, simply explain to me, what have I learned after reading Hamlet?
Slashdot gets worse every day... Pipedot: News for nerds, without the corporate slant
We don't watch news reports from years ago (even though we may be taught what happened). Why are instructors forcing their students to read books that are hundreds of years old?
But hey, that was a secondary point anyhow. My point was always that no ammmount of technology can help if instructors are unwilling to utilize it.
<rant>
A great deal of money is being spent to teach instructors computer literacy, with no benefit besides instructors being better able to surf the web. Not to say some instructors don't make use of it. Just the idea that since the computer is a buzzword, teaching technology to instructors (many of whom don't have any need for it) has become a fix-all... a substitute for actually improving the education system in any meaningful way. Teaching them a skill, and having it benefitially utilized are two, unrelated, and entirely different subjects. The TV and VCR just happen to be a good example of technology everyone knows how to use, that could make huge improvements in education, but has been of practically no impact.
