virtualdub and composite over s-video capture???

[dragonfly]

Hello,

I want to do a vhs-capture with my tv-card ( pinnacle pctv rave ). In virtualdub you can use 3 modes for your source: tuner, composite and s-video.
I have a tv-card which handles s-video sources. My vcr has a scart-output/input, but no s-video connection.

I bought a scart adapter like this one (http://www.s-video.nl/media/copy_scart_56.jpg) and connected my vcr through a s-video cable from that adapter to my tv-card.

I always watch tv with Dscaler (which is the best tv software out there ;)). In Dscaler you have not 3 but 4 video input types. Tuner, s-video, composite and composite over s-video. Now this last one is a great feature for people in my situation. Because the output on my screen is almost perfect. I made some screenshots of the differences.
In total 5 pictures: 3 of the dscaler modes and 2 of the virtualdub modes.
DsCaler Tuner mode (http://www.elfare.cistron.nl/bestanden/DsCaler%20Tuner.jpg)
DsCaler s-video mode (http://www.elfare.cistron.nl/bestanden/DsCaler%20s-video.jpg)
DsCaler Composite over S-video mode (http://www.elfare.cistron.nl/bestanden/DsCaler%20Compostie%20over%20s-video.jpg)
Virtualdub s-video mode (http://www.elfare.cistron.nl/bestanden/vDub%20-%20S-Video.jpg)
Virtualdub tuner mode (http://www.elfare.cistron.nl/bestanden/vDub%20-Tuner.jpg)

You might think what the heck is my problem. Well my problem is that I can't use the feature "composite over s-video" in virtualdub which produces the best picture quality output. My tuner gives some vertical lines (which you can see here (http://www.elfare.cistron.nl/bestanden/DsCaler%20Tuner.jpg) if you look closely).
When I use s-video as my source to capture I get this (http://www.elfare.cistron.nl/bestanden/vDub%20-%20S-Video.jpg) and I want the best :D . If I could do a capture through DsCaler I would use it right now.

Is there a way for me to use my s-video through the scart adapter in virtualdub without getting that noisy picture.
Perhaps this post is a suggestion for the virtualdubmod programmers to implement composite over s-video as a capture source. :D

Im in the states so that cable is not really popular here. The
only thing i ever had one of those for was a psx years ago.

However im posting because i really think your SOL. Ive seen
how RF2svideo and composite2svideo look...horrible. In fact
i use a tv-out card to a tv now so my son can watch his movies
and play his games...and when i used the composite2svideo i
almost cried because i know i had to move a 100 pound tv that
accepted svideo so he could use it.

Now i have also seen how SCART2composite looks and that looks
just as sad. Atleast it did on psx. Your best bet would be to
get a different tuner.

I honestly cant say i have ever seen a adapter that would suffice
my taste in captures...infact i couldnt see anybody living with it.

I still dont understand why you cant do it they way you want. I dont
think the svideo via composite option or whatever improves that much..
atleast it didnt for me.

There is other apps taht have that feature though...i think :-(. I
think amcap has that and VirtualVCR maybe?

btw you need to sharpen the heck out of that picture...or else no
filter could help you...unless you satisfied with it as is.

I think I get the question...

The problem is the SCART adaptor is only broadcasting a Composite signal... It cannot split a composite signal into a HIGHER QUALITY s-video signal unless the source carries an S-Video signal as well.

The only way you will be able to get S-Video properly, is if you have a S-Video connector actually on the back of your box... The card is working fine, it just needs the right signal in the input.

I have a S-Video on the back of my Digital Satellite system, the quality is great (bar a few problems).

I used to have the same problem, till it was explained/I realised what the matter was.

Hope this helps

Thanks for the reply guys.

It make sense that the scart adapter can't split the signal through s-video correctly. I have to use the scart to watch the video via composite over s-video. But to record it I am now forced to use the tuner signal :( , because my vcr has no s-video.
Composite works on the other hand, but isn't that great.
