XENA LH Quality Problems / Interferences with analog capture
Hi,
I have a XENA LH with KL-box and have to capture from analog source (Beta SP). While the image is perfect on the screen that is directly connected to the SP-Deck, the image in Machina and on the KL-box-screen has some gray horizontal bars on (see jpg). These bars change with the motion of the image; when the person moves his head down and up, the bars roll down and up.
I hav two stills: 1 taken from xena analog capture an 2 from analog capture with a dv-deck.
1 – https://www.totho.de/xena/xena.jpg
2 – https://www.totho.de/xena/dv.jpgI have also tryed different cables and even used the i/o-cables that came with the xena card instead of the kl-box, but nothing changed.
And using a different analog source does not help it too.My config is:
– Tyan S2676 Board
– 2x Xeon 3,2 GHz with HT
– 2 GB RAM
– ATI firegl V5100
– some additional controller cards for SATA or firewire800Can somebody help?

My eyes might be playing tricks on me, but I don’t see any “grey horizontal bars”.
The closest thing I’m seeing is what looks like field interlacing artifacts on number 2. Is that what you are talking about? You can really see the “jaggy effect” on the frames of his glasses and the side of his left cheek.

Hi,
interlaced images are not the problem.
Maybe your screen is darker than mine or your contrast is quite high. I gave some contrast to my jpg 1 – the background behind the guy shlould be black or at least unichrome:

Oh ok, I see it in that second picture.
