I have tried to capture analog video using s video input with no luck. I am
obvisouly doing something wrong. Any suggestions would be appreciated.
 
hi chuck,

You need a converter. one that converts your cinch cable to usb or it won't
work.
 
I am new to making movies so bear with me if I have simple questions. I was
told that I can hook my sony analog video camera directly to my gateway 825
and the signal will be converted from analog to digital. It appears that
this is supported in the help section of movie maker. Any help would be
appreciated.

Woody, thanks for your response
 
Open MM -->File-->Capture Video...

1. What "Available devices:" are listed?
i.e...
ATI Theatre Video Capture
IBM PC Camera, etc.

2. What "Video input source:" options are available, when specific device
is selected in paragraph 1, above?

Another means of determining analog capture device capabilities is...
1. R-click My Computer and select Properties
2. Select Hardware tab and click Device Manager
3. Scroll downward and expand "Sound, video and game controllers"
4. look for video device driver descriptions that contain the letters
"WDM"

Your input device must include WDM support for legacy analog captures in
order for MM to work with analog input sources. With properly installed WDM
based drivers, MM will indeed capture streaming video from analog input
devices; synchronized audio capture is however, another can of worms
altogether.

Please report your findings to the group so that we may all have some idea
of exactly what make/ model of video input device is actually installed on
your system. Gateway 825 means absolutely nothing to anyone not using a
similar system so, what we really need is more detailed information
regarding the nature of your specific video capture input device(s).
 
Thanks for the info, I will try it tonight when I have some free time to dig
into it.

The avaliable device listed is a AverMedia AverTVmpeg video capture. When I
expand Sound,video and game controller it shows that I have Legacy Video
driver and when I click on that it shows WDM for window capture win32. Once
again I appreciate any help.

Ok, that helps...

We have now confirmed that you do indeed have analog capable hardware, WDM
driver support is installed and registered with the system, and the hardware
OEM/ Supplier is AverMedia...

(http://www.avermedia.com)

We might learn a bit more about your capture hardware, via WinXP System
Information...

1. Start-->Run-->type "msinfo32.exe" without quotes, press <Enter>

2. Expand "Components", and ignore "multimedia-->*Codecs". Stay focused on
any visible entries referencing AverMedia; i.e. AverTV, Go 007, EZMaker,
etc.

My own best guess is that you are probably using the AverTV Go 007 pci,
which has a healthy dose of media capability. Don't know how good it is
qualitatively, but the listed feature set is certainly well defined.

Assumptions:

WinXP SP-2
MM v2.1
DirectX v9.0c
(Start-->Run...-->type "dxdiag.exe" without quotes, press <Enter>)

Since I am unable to determine the specific model of your capture hardware
from the limited info currently available, we really need to verify that an
S-Video input source is actually being seen by MM and that it functions
correctly. Since you did not respond to this question from my previous
post, I must reiterate...

1. Open MM-->File-->Capture video...

2. Under "Available devices:" please insure that AverTv is properly
selected as your primary capture device.

3. Within the same dialog window there exists a section labeled "Video
input source:".

Select "Video input source:"

Insure that the "SVideo" input option is selected and not grayed-out or
otherwise unavailable; this is where you tell MM to use SVideo -- if
something is wrong here, it will never work.

--- The following checks will help confirm that a dialog exists between your
hardware and MM...

4. Immediately below the "Video input source:" dialog, and offset slightly
towards the right, you should see a button labeled "Configure...". This
label opens the "Configure Video Capture Device" dialog box and only appears
if your video capture device uses Windows Driver Models (WDM) drivers. If
your capture device uses Video for Windows (VFW) software drivers, a dialog
box specific to the selected device appears, and this dialog box lets you
adjust different video settings. Thus, the availability of a "Configure
Video Capture Device" options dialog offers further confirmation that your
analogue device supports WDM

Select "Configure..."

The Configure Video Capture Device dialog is appropriately based upon the
known capabilities of your hardware, which is exposed through the WDM
driverset. You should now see an option button labeled "Video Settings"

Select "Video Settings"

In this dialog, you should be able to set capture parameters specific to
your project needs; i.e. Video Standard = NTSC_M, Frame Rate = 29.970, Color
Space/ Compression = UYVY (or YUY2, or...), Output Size = 320x240, etc.
Rather than worry about changing these parameters for the moment, let's
simply stick with the defaults as listed above until we are more sure of
exactly where the problem lies.

--- If your media software can display the inbound SVideo stream on your
monitor, MM should be able to capture it. Please conduct the following
test...

Connect S-Video output from an alternative video source, VCR/ DVD/
etc....

NOTE: A VCR equipped with S-Video output works well for this test because
we need not be concerned about commercially protected media (DRM) issues.
Instead of inserting a VHS tape, simply select any locally available TV
channel and configure the VCR for S-Video output; provides a constant stream
of source video.:-)

1. Are you able to display the resulting video on your desktop,
using AverMedia software?

2. Are you able to capture the video stream with MM?

This should tell us whether the capture issue lies within your hardware
configuration or is exclusive only to camcorder output. Thus, if MM
captures correctly from other S-Video based output devices -- VCR, etc. --
we can eliminate system hardware from the problem equation and subsequently
focus all of our efforts on the camcorder...

http://www.papajohn.org for possible solutions...see "Digital
Camcorders" and "Analog Video Capture".

If MM is unable to capture from any SVideo based input source, hardware
installation, configuration, or an undetermined compatibility issue is most
likely the culprit. Because I am completely unfamiliar with your hardware,
I probably would not be able to provide much further assistance in that
regard. Perhaps someone with first-hand AverMedia specific knowledge will
jump onboard.

Please report back on your findings...
