Meetings - get on mailing list
FAX list
Fill out roster for SIGMULTEC
Special Interest Group on Multimedia Technology
At 5:00, multimedia CD ROM awards
If interested in helping out, various producers of multimedia CD ROM, how they developed scenarios, comopression technology, video, stills, production and so on.
Magnet - highest caliber - all design on Mac, translated to PC before they are through.
3 open floors
CDs for Fortune 500 firms
The Time Almanac people may come to do a presentation.
Mac is still preeminent design tools
They author in their
John Graves Introduced
Ed Forsee - membership chair
Developed instructional material in 80s - now no longer any good
Video disc programs - put on CD-ROM
Big fan of questions and answers
[full house]
= Frank Garber, United States Video Corp.
Converting existing material to CD ROM technology.
Bob mentioned some video tapes, slides
Start with attention getter
[heart beat - you shouldn't be drinking while driving]
What you just saw was MPEG1 digital video playing off of CD ROM
People want digital video on CD ROM,
indeo
MPEG
MPEG2
Was full screen
That type of quality before could only be on video disc.
United states
since 1984
video disc
computer technology cheaper / faster run from a CD ROM
brochures at the front
Several small demonstrations starting with national technical information service produced by OSHA, inside were slides, audio tapes
Seven programs - no slide projector /tape player needed
Loading up under Windows.
[Automatically plays with sound - Heat and Cold Stress - picture on left, text on the right - essentially slide show with voice over - some slides are cartoons, others bullets]
OK, I'll pause this now. This is 30 minutes. Now it is interactive. VCR buttons on the top. Text matches audio. If you lack sound, you can read text.
Q: What sound board?
Any standard off the shelf equipment.
In fact, MPEG 1 video, that was a real magic board purchased from CompUSA.
Now that we have this presentation on CD ROM we have an index button. To see frost bite damage, #58, select it and click OK. Then, to go back to 7. Very quickly go back and forth.
Full size option. Mouse goes back to mixed image and text display.
Another version - full screen slide program - images full screen with YOUR voice over as for lecture.
Another Icon - show maker allows rearrangement very quickly - text and audio will follow. I am going to select 64, 7 and 49 then press Show and it will now sequence images in that order.
Index shows four slides in the order sequenced 1, 2, 3, 4 once done, save in temporary file
Go to custom show full screen and four images, no audio are in the sequence selected. So that is how quickly you can rearrange the slides.
As you saw, 35 mm slides, converted to digital files.
Q: Full screen image qith audio?
You can. Play sound in background.
Q: What size was the file? How much overhead?
Less than a meg, 256 color, full screen 1/4 meg. 1/4 screen is 1/10 meg.
Q: Is this an off the shelf product?
Isn't currently. Possible.
Q: Is there something off the shelf that we could use?
There are. Compel. Persuasion.
As a conclusion on this.
Q: I was just wondering. To bring in slides, could use PowerPoint.
Will it do all the things you want to do. What is the overhead. Where will it work.
Q: I want to congratulate you. Custom slide show ask for this.
No easy way in Director.
We have Director too. That software we use comes from opthomologists. Reseqence capability, that's why is it there.
Another area here.
We were also approached by NTIS in regards to National Institute of Mental Health. Three sided video disc program from 6 - 7 years ago.
Wanted to look at CD ROM conversion. That's what I'm going to bring up now. [in Director]
The menu text menu on the left, the video on the right.
We looked and concluded it could all fit on one CDROM. As you look through old system you had to change discs. Same 13 areas on this screen. [comparing two systems at same time]
On PC, this will be Indeo video. [small video palys]
The Indeo video is important because if you have a Windows system, you don't need MPEG 1.
Indeo video is software, 250 x 180 18fps
To play on the other system, would need to change video disc.
[video has some latency - sound is very good]
With CD ROM technology today, 600 MB will hold between 60 and 74 minutes. You used to put 30 minutes on a video disc. Even though the running video was over an hour. We found old was to use video for still. ON new system, used voice over ONLY with still image.
Old video discs wasted video frames with stills.
Other icons - glossary, highlight word - see definition.
Still prototype - in opening, music, moving text, file drawer opens up.
Program may be revised. Demonstrates how information that already exists can be moved onto CD ROM.
Q: Why Indeo?
A Windows based Windows video
It could also work with QuickTime. Video could also work with Director
Q: Cinepak?
Indeo is very common.
Q: Can you import Indeo, AVI or Quicktime?
Yes.
Q: Indeo works on Mac too.
Here is Congressional Record.
Look at Table of Contents, shows senators
Q: Is this HTML?
This is Viewer. It has text search, include images and audio files.
Text is what's printed. Audio button. Video button. [jerky movie of senator speaking]
Q: This is Indeo Video?
Yes. [Senator drones on ..]
Q: Video from CSPAN?
Text would be obtained from CSPAN closed caption. Idea was to capture closed caption text. Any text you search should take you directly to that speech. If you look up GATT, senators listed, words highlighted in text.
If you just wanted to listen, two buttons maybe.
Q: She has more to say ...
In theory, it will continue for 8 to 10 hours.
You have options [search was on GATT and econ*]
Real Congressional Record is changed. This is what really happened. Here is one with a very long pause, he must have been thinking of something. [I make these comments ... ... .... .... ] That's the way it really happened.
Q: This is a project with the Library of Congress.
This is very, very early project. Eventually through internet, big products. Who knows how they will be used.
Q: How will this be used in ....
Q: Can you start the video anywhere?
You can type in whatever text.
Q: How big is that file. Six speakers ..
9-10 MB per minute at this quality with Indeo. Huge job on CD ROM.
Compression services - see me after.
Q: How do you link the text to the audio visual material
In this one, simply canned. In real application, link to closed caption.
Q: With closed captoin, how would someone highlight.
If you don't have closed caption. Someone might have to create Table of Contents or Index.
[another Senator played]
One more MPEG sample to show.
Full screen video plays with $300 MPEG card. $200 at show.
Yesterday, Computer City has bundled CD and video card.
Just played - computer locked up.
Q: Time to link text and video - jump to 38th minute.
Simplest way is to use closed caption text. That can tie in.
Q: Does it somehow use the time code as a reference to the video?
MPEG cannot recognize time code. Also you need to tie that in to some way to search it.
How do you go into that MPEG file at that point.
Q: I don't know of any way to go to a particular point in an MPEG segment.
That CAN exist without too much difficulty.
Q: Because MPEG is compressed, with interframe compressioin, you can't enter at any frame. It must be a key frame.
One more demonstration from the Library of Congress. Old McKinley demonstration footage.
Q: I think it is important to note that - if you have media you're using - it can be done.
Someone asked eariler about compression program. This is Compel.
President McKinley taking his oath. - could be full screen. No audio with this. If it is digital video, you could download it from home.
Q: Kaleida - has scripting language This allows new kind of interactivity with objects. Demos are two of the most awesome, slow, but new potentials. Most of these examples are like slide shows. Interactivity really grabs the users. You go in and interact. WWW.KALEIDA.COM
$795 Free player available.
How you get slides, video, make it all work together.
Ofiesh: I'm 76 years old. Started Educational Technology at Catholic University in 1965. Cornucopia of tools today. I don't even remember what a filmstrip is. We used to cut up film strip, put them in slides. Create multimple choice and true false. put between.
Crude and primitive, stale interactivity. Even so, we saw 50-75% improvement, cut time by 1/3rd. Now we've got repurposing.
How to make silk purse out of sows ears - pedagogically sows ears - tools to salvage these materials.
7-8 year old children, scanning pictures, grabbing video. I was so excieted I'm looking back, I just remember - take carosel tray full of slides, after lined up properly, dropped on the floor - all spilled, hours spent!
