Audio directly into line-in

[volcomstone02]

I am using a Hauppauge WinTV Go card. Only problem with this card is
the mono output. Currently I have the the tv cable going into capture card, with an audio lead going from that to line-in.
Would I get stereo output if I jacked up an audio cable to go straight to the line-in, bypassing the capture card.
I thought I would ask this before messing about with cables.
Cheers

P.s I also read a forum about boosting the mic-in , could anyone give anymore details on what this does and how to do it.

regarding the stereo line in, that's true. if your tv card has onmy mono out, and u need stereo, use line in, directly from your source.

however, sometimes, the signal level is too weak, especially if u use long cables to the line in, and may result in noises while capturing. the mic input of your sound card, on the other hand, is designed for different frequency range, and different (lower) input levels. on top of that, sometimes the mic input has a 'boost' feature. you should search the mixer (especially if you've got the one that came with your sound card) for this option.

regarding the quality, some ppl consider it enough to use the mic in, especially of they can live with mono only (such as me). it's up to u to test the various configurations, and decide which one you like best.

Well, sorry avih, but:

if you haver a mono vard,there's nothing you can do to make it stereo.

bt878a has such a feature on chip - and a win9x driver to support it - but the result is - well, let's say, mono.

My recommandation: buy a stereo card.

If I do have an audio cable going directly to line-in will the capture still be in sync.
And because of the way this house is built, the cable from the decoder to my capture card is 13 metres. In %age, about how much
in video quality am I losing having a cable this long as opposed to the average 1 metre long cable.
I know I am losing quality, but by how much.

You can't of course make the Mono Card output stereo but recording from my VCR I always use the line-in on my soundcard to get the stereo sound. Using any decent capture program you can mix the video source as well as any audio input.
So basically the answer to volcomstone02 is yes.

(But I wouldn't even try using a 13 meters cabel.:( )

my source is stereo (digital sat-decoder), but my cap card is mono. i can connect the line out (stereo) from the sat-decoder to the line in of my sound card and capture in stereo using vdub. no problem about that. but since my cables are quite long, and i want max bitrate for the video, i use mono cap, through the mic-input, from a mono output from the sat-decoder (it can produce either mono or stereo). this way the mic also filters the signal a bit, and i'm happy with the result. so a stereo card is not neccessary. on top of that, i use the composite input for better quality than rf-input, so my cap dard doesn't produce the sound anyway for this input, neither mono nor stereo. line in or mic is the only option if u use s-video or composite inputs.

Can someone tell me why this happens:
Here it is.

DVD to AVI (wanting 700mb to fit CD)
30 minute DVD material, at 2993 bitrate, 192 KB Audio, = 700MB

VHS to AVI (wanting 700mb to fit CD)
30 minute VHS material, at 2993 bitrate, 192 KB Audio, = 500MB

Why was the VHS smaller than it should have been.
I have heard a bit about how DVD and VHS have a different amount of lines, etc.

If this is the case is there a VHS to AVI calculator out there so the correct bitrate can be calculated to fit a CD.

*sigh* This has been discussed soooo many times.
