Motion Blur/Bad Quality when capturing uncompressed

[Ezekiel 4:12]

I have a Pinnacle Movie Board Plus with a Intel Core 2 Duo 6320 and four gigs of ram, using VirtualDub to capture from my cable box via composite. I can capture just fine uncompressed, MJPEG or Huffy but the quality is sub-par.

Even at best the quality is not near as good as the image on my TV, but when there is movement the quality takes a severe dip as if there is some sort of motion blur going on. It's so that i cannot tell the difference between uncompressed and using MJPEG compression (configured for highest quality).

Is it an issue with my capture card not being up to snuff or is there a setting i'm missing in VDUB?

What you are probably seeing a result of interlacing. TV is interlaced, interlaced footage will look fine on a TV but not on a computer. If you are deinterlacing, it won't look too good on either.

Ensure you are capturing as interlaced and burn to a DVD to play back on a TV for a quality check, don't rely on what you see on your monitor.

Also, TVs have a lot of circuitry built-in to clean and hide many small flaws in the image. You get so used to not seeing them that when you do see the raw footage, it can be surprising just how bad it looks.

Thanks for the help. Now that you guys mention Interlacing, it does look like that's the problem. Much appreciated.

composite>>don't expect to get anything good with this
MJPEG >don't expect to get anything god with this
