Capturing VHS with my PC
Questions:
I have connected my VHS recorder directly to my pc using scart with an input
and output switch. I have also connected using S-Video lead but find that
even though I can get picture and sound, there is no colour. I am using
Ulead VideoStudio 7 and have adjusted the configuration accordingly ie to
PAL, but no matter what I choose there is no colour. I even tried connecting
my DV camcorder, but the image I get on the camcorder is also black and
white. Is it possible the scart connection or should I trying using the
firewire connection also?

Answer:
The reason for the black & white picture is the S-Video connection. Only an
SVHS VCR will be able to output the video on an S-Video lead. A standard VHS
VCR will only put a B&W picture over S-Video because the colour and picture
(chrominance & luminance) parts of the signal are on different cables, but
the VHS VCR can not split them. Therefore the colour part of the video
signal that the S-Video input is expecting will be missing on the
chrominance cable and ignored from the luminance cable. To get a colour
picture from the VHS VCR you will need to connect a composite lead into the
PC, if it has one, or convert the composite to S-Video with a converter.

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

my thoughtd(that may be wrong) hence the post:

Why would a VCR have an S-Video connector then ?
Why would/do DVD players and digital camcorders output via S-Video ok then ?
I thought S video and SVHS were not really much to do with each other ?

yes.
s-video across a scart connection only works if both ends understand
the signal.
a scart socket uses the same pins for different uses , depending upon
what is being sent/received.

at least one answer here , by me , explains exactly what each pin does
, and why you see B&W


quote:

a fully wired scart will not make any difference if the tv cannot
accept an s-video signal.

look at the scart pin definitions and you will see that in different
modes , a scart socket expects different signals on the same pins.

on a s-video capable scart the following pins carry the signals
required

13 c out ground
15 c out
17 y out ground
19 y out

on a conventional scart the same pins do the following

13 red ground
15 red
17 video output ground
19 video output

so you can see that only y out is feeding where a conventional scart
would output composite .... therefore no colour signal present.
