QI/QTª QUICKTIMEª SOFTWARE COMPONENT 
---------------------------------------------------------------------
With the release of QI/QT, the QuickImage 24ª Digital Video Card from Mass 
Microsystems is now QuickTimeª compatible!

QuickImage 24 users are now able to make digital movies from any standard 
video source by using the QI/QT Component and the new QuickImage INIT v. 
2.5 with any QuickTime-compatible recording software application. 

QI/QT
---------------------------------------------------------------------
ÒQI/QTÓ is a QuickTime component, not an application.  QI/QT will enable users 
to use the QuickImage 24 card in conjunction with a QuickTime-compatible 
ÒRecorder applicationÓ.  When QI/QT is installed properly, you will be able to 
access the QuickImage 24 card from within the application.  QuickImage will 
automatically be recognized as a QuickTime video digitizer from within any 
QuickTime-savvy recorder application, and will appear on its menu.

---------------------------------------------------------------------

	¥ Macintosh II family  computer (NuBus, 030 /25 mHz preferred)
	¥ QuickImage 24 video capture card
	¥ 24-bit or 8-bit color display and interface

General QuickTime Movie Hints & Comments
--------------------------------------------------------------------------
¥ The smaller the picture, the faster the frame rate.  QI/QT frame rate speed is 
optimal at 160 x 120 (standard 1/16 size).

¥ Users wishing to record directly to RAM who have more than 8 MB in their 
machines need to enable the 32-bit mode.  The QI/QT component is fully 32-bit 
clean, and with 20 MB in your machine it is possible to record up to 42 seconds 
of QuickTime at  the standard 1/16 size.

¥ Recording directly to RAM yields fastest frame rates. A 24-bit mode, standard 
1/16 frame size with 8 megs of memory will yield about 12 seconds of QuickTime 
movie duration.

¥ Mac CPU speed and disk access speed are key factors in determining frame 
rate.  

¥  The QI/QT component provides both 24-bit color and 8-bit color. Eight-bit color 
will give faster frame rates.  

¥ Unlike many other digital video cards for the Macintosh, QuickImage 24 
provides dual video input connections, either of which can accept Composite 
NTSC or S-Video. S-Video compatibility allows users to connect any Hi-8, S-
VHS (Y/C) camcorder or tape deck  directly into the card without recombining 
the signals, preserving the higher quality signal available with S-Video.  The 
two inputs are software switchable, allowing you to easily move from one video 
source to another.

¥  DonÕt forget image capturing!  QuickImage 24 provides excellent quality 24-bit 
color still captures up to 640x480 in size and supports odd or even field or full 
frame control.  Version 2.0 software (included with this upgrade) supports 
sequential capturing with ÒQuickStripÓ and JPEG compression.

¥ QuickImage can be accessed through Hypercard via QI/QT.  As a 100% 
QuickTime-compatible componenet, QI/QT is compatible with HyperCardÕs set 
of  QuickTime X-commands.

¥  If youÕre a certified developer, and wish to integrate the capabilities of 
QuickImage into your application, send an AppleLink message to us at 
ÒMASS.ENGÓ requesting the ÒQuickImage DeveloperÕs KitÓ.

Audio Compatibility & Use
---------------------------------------------------------------------
At some point, you will want to record sound into QuickTime movies.  QI/QT can 
be used effectively with the Macintosh built-in sound recorder within 
various recorder applications.  In addition, the MacRecorder¨ Driver v. 
1.01 (Macromind/ Paracomp)has been tested and found to be compatible. 
Simultaneous recording of video and sound will slow down the video capture 
rate.
