1.  Important Notes
---------------------------------------------------------------------------


We strongly recommend that you turn your computer off anytime you connect 
or disconnect the QuickCam from either the parallel port or the keyboard port.

If you are a Windows 95 user, your computer may crash if you try to run both 
QuickPICT and QuickMovie at the same time. 

Be sure your monitor is displaying at least 16 bit (high) color. (See Control 
Panels:Display:Settings in Windows 95 or consult your manual for Windows 
3.1-based computers.)

Do not plug the keyboard power adapter into one computer and the parallel 
port connector into a different computer.  Doing this will void your warranty.


---------------------------------------------------------------------------
2.  Parallel Port Modes
---------------------------------------------------------------------------


To experience QuickCam's true performance, it is important that your parallel
port be set to Bi-directional or faster.  To get the fastest frame rates
for preview, video capture and still capture, your parallel port must be set
to Bi-directional or faster.  

There are three types of communications modes that your computer's parallel 
port can use to talk to QuickCam:

· ·	Nibble (or Compatible), the slowest mode;
· ·	Bit (or Bi-directional), medium speed mode; and
· ·	ECP, the fastest mode.

All Pentium class machines are capable of bi-directional communications;
however, they are usually set up for the slowest mode.  To set your computer
to bidirectional or faster, you must change your BIOS Setup.  Please refer to
your computer's technical reference manual for instructions on changing the
BIOS setup on your computer or refer to your computer manufacturer's or your
BIOS manufacturer's website for support.

3.  Getting the Best Picture and Frame Rate from QuickCam
---------------------------------------------------------------------------


To get the best image from your QuickCam, first make sure that you have 
adequate lighting. All of the other image adjustments depend on the presence
of an adequate amount of light. As a rule of thumb, if the lighting is such
that you would use a flash with a normal 35mm camera, you need to add more
light for your QuickCam. This is probably true in most home environments where 
illumination is provided by a single light source.

One of the most important factors in getting the highest possible frame rate
is having enough illumination. The less light there is, the longer the shutter
will have to stay open to capture each frame, which results in lower frame rate. 
Simply by increasing the light level, you can decrease the necessary shutter 
speed (the Brightness setting) and increase the frame rate.

If you are using a Color QuickCam, make sure that your monitor is set to 
display the same number of colors or grays as the QuickCam is capturing. For 
example, if you capture video at thousands of colors, make sure your video 
display adapter is set to display thousands of colors. If the QuickCam has to 
dither the image to match your display, frame rates will decrease. 

If you are using a Color QuickCam, use the Thousands (VIDEC) setting (the 
default setting). In this mode, Color QuickCam implements VIDEC, which will 
increase frame rates.

If you are using a Color QuickCam and there is enough light, you may get 
increased frame rates if you turn off the Low-Light Image Filter checkbox in 
the Camera Adjustments dialog. 

If you are using a Color QuickCam and do not need the maximum amount of 
detail in each frame, choose a reduced Sharpness level. If you choose the 
middle or the lowest value for Sharpness, you will get higher frame rates than
if you choose the highest Sharpness value.

To increase your frame rates, choose a smaller image size. Capturing a smaller 
image size results in faster frame rates.

Make sure you're running only QuickMovie. Close any other application that 
may take processing time away from QuickMovie.

When recording a movie your on-screen frame rate will appear to drop. This is 
because QuickMovie is making sure that you get the full rate saved to disk
first; screen updates are secondary to captured frame rates. When you play
back your saved movie, you will see the full frame rate captured by QuickMovie.

To playback a movie recorded using VIDEC compression on a different 
computer, you will need to install the VIDEC decompression software 
(VIDEC.DLL). This software is available on the Connectix Web page and 
Connectix online service forums. See How to Contact Connectix Corporation.

4.  Known Issues
---------------------------------------------------------------------------


On HP Omnibook 800 models, connecting the QuickCam into the parallel port may
cause the application to fail.  If you cannot get a picture, try plugging
into the parallel port on the docking port instead of the parallel port on
the Omnibook itself. 

Do not attempt to use the Full Screen mode in QuickPICT, QuickMovie or the 
QuickCam Screen Saver in low memory configurations (12 megabytes or less).  
The image may freeze or produce unexpected results.

If you take a picture to the clipboard using thousands mode (Windows 3.1 
only), you will not be able to view the picture using Microsoft Paint or the 
Clipboard Viewer.  The image is, however, available to other applications 
which support 16 bit images.

If you are a Windows 95 user, your computer may crash if you try to run both 
QuickPICT and QuickMovie at the same time. 

In the QuickPICT Save dialog box, changing the File Type in the pop-up menu 
does not change the extension of the file name. You need to change the 
extension manually. If you select Bitmap use .BMP, JPEG use .JPG, TIFF use 
.TIF, AOL ART use .ART.

If you have a grayscale QuickCam, the Color Camera installer will disable the 
original QuickCam driver.  You'll have to reinstall the original software to
use the grayscale camera again.

Do not use the screen saver and auto capture at the same time. There is not 
enough processing power available for the same camera to display a full screen 
moving image while also saving a still image to disk.

If you've ever added a PC speaker driver (speaker.drv) to your system, it is 
possible your computer will crash if you try to use the QuickCam software with 
the driver installed.  We highly recommend uninstalling the PC speaker driver
before attempting to use the QuickCam.

VIDEC compression is not available in QuickPICT or many other applications 
that use the QuickCam to take a still picture.  It is designed primarily for
video capture and is available only in QuickMovie. 


---------------------------------------------------------------------------
5.  Windows NT Notes
---------------------------------------------------------------------------


The Windows NT driver for the Color QuickCam was not ready in time to be 
integrated into this installer.  It has been added separately to this CDROM
in the directory called NT.  The Grayscale QuickCam Windows NT driver is
integrated into this installation program.

Under Windows NT, the grayscale QuickCam may playback a movie at double
speed.  Disabling audio in QuickMovie will correct the problem. 

We strongly recomend that Windows NT 4.0 users install Microsoft Service
Pack #3 or later. 


---------------------------------------------------------------------------
6.  Installing both QuickCam and Color QuickCam with Windows 95
    (Advanced Users Only)
---------------------------------------------------------------------------


NOTE: You only need to read this section if you have a Grayscale QuickCam
and a Color QuickCam AND want to switch between both cameras on the fly.

This installer will disable previous versions of the QuickCam driver that may
have been installed. It is possible to install both Color QuickCam and
Grayscale QuickCam and switch between the two in the Multimedia Control Panel.

1) Run the QuickCam Installer twice, selecting the Grayscale QuickCam first
and Color QuickCam/Color QuickCam2 the second time.

2) Open the Windows\System.ini file and make sure the following lines are in
your [Drivers] section:
MSVIDEO=qccolor.drv
MSVIDEO1=quickcam.drv
(Note, if you have other video input devices you can set them to MSVIDEO2, 
MSVIDEO3, etc.)

3) Reboot the computer.

You should now have both cameras entered in the Multimedia Control Panel, 
Advanced Tab under Video Capture Devices. To switch between cameras, select 
the driver for the current active camera and click properties. Click the 
"Do not use this video capture device." and click "OK. Select the camera
you would like to use and click properties. Click the "Use this video capture 
device." and click "OK.
