Analog capture card

A

Adam

I have an analog capture card, and am wondering what the optimal specs
(frame rate, resolution) for capturing video would be, both for S-Video and
the Red-White-Yellow cables. Thank you in advance for your help.

The NTSC standard for S-Video or Yellow composite video in North America is
SD 480i. The Red cable is for right channel audio and the white cable is
for left channel audio.

Another question - I had always thought that S-Video was higher quality than
Yellow composite. But if I understand correctly, you said that the NTSC
standard is the same for both of them...?

Yes, S-video is of higher quality since the color signal is separate from
the B&W video signal, however the NTSC resolution standard for both of them
is the same

If you have a card that will accept S-video or composite then you just send
S-v

The quality difference is inherent in the connection type. An S-Video
connection introduces less degradation into the video than composite does.
Note that cable length and quality also enter into it. S-Video does not
transmit Audio, so you will still need to connect the two (red-white) audio
cables when you use S-video.

Resolution and picture quality are related but they are two different
characteristics. The one describes the total amount of image data in each
video frame, the other is about the difference in appearance between the
source video and how it ends up looking on-screen (or as a capture file)
using either one of the two different types of cable.

To get the best from s-video you also need an s-video original signal from
an s-video player.
