I think you got the wrong letters in your msg…
>I saw an *IBM* version of an encyclopedia entitled "It All Started with
George"
>(history of the Presidents), and it did have CDTV. When run on an "oarnge
book"
>box, it looked pretty good. The IBM woman says that CDTV really eats up
disc
>space, so you have to chhose the clips carefully. For "Green book"
boxes…
Do you mean CD-XA, MPC or something? CDTV is only the Commodore product.
JBI.

I didn't know what CDTV was. I guessed that it ment "storing video clips on
compact disc[-ROM]. I didn't know it was a Commodore doo-dad.
History of the Presidents has sound and video on it. My comment about
"green-book" quality (lower-rez, using one frame in three) is for CD-XA
capable machines. The much smoother video is for the "oarnge-book" (MPC)
machines.
Sorry for the confusion.

"The Presidents" uses the same movie technology as the "Mammals" CD from
national geographic, ('Presidents" is also a NG product), except that the
software for the movie production has been improved significantly in a few
different ways. The files are compressed much more than in "Mammals", to
as little as 40% of the size in Mammals. In addition, better control of
the color palette provides better picture quality on playback. In addition
to this, audio data is interleaved into the data file with the animation
video for playback of sychronized sound narrations. In Mammals, the
software was not advanced far enough to include sound. THe video in
Presidents is somewhat better than Mammals, and includes sound, but does
not match DVI video or video from videodisc in a window on screen such as
from an IBM M-Motion adapter. The playback of sound from Presidents can be
accomplished on any machine which meets the MPC standards for audio. The
video is MCGA, 320X200 pixel, 256 color.

The 'move technology' that you refer to in Mammals is basically the same as
in Grasp from Paul Mace Software. I can take any of the .DFF files off of
the Mammals CD and play them in my Grasp programs. For info on GRASP go
GRASP!!
How R U doing audio/data interleave? R U using CD-ROM XA?
Oh-oh. What you describe sounds like the "Green Book" disc I saw at CD-ROM
Expo last week, particularly the 320×260 pixel.
But I also saw something else that was full video…excellent picture, high
rez, perfect sound sync. I thought it was all on an "oarnge book" disc.
Are you telling me that the video portion was actually coming from a
*Videodisk*???

No, not from videodisc. THe movie portion of the Presidents is entirely
done using software. THe data file contains the animation and audio
information, and a playback routine puts it on the screen. The data has
nothing to do with any CD formats, it is simply a DOS data file. It works
as well of floppy drives of hard drives as off CD's. IBM has an internal
product they call "moviemaker" which creates the files. It is presently an
internal use only product. It works by digitizing images from a videodisc
original to product the movies which are delivered in the final
application. The playback routines have been used very successfully with
LinkWay, which is the development software used for The Presidents, but it
will also play under many other DOS applications, if the application allows
the execution of a DOS program.

This Moviemaker stuff sounds great… I hope that IBM publishes it….
