Line down the middle with movement

[jriker1]

All my DV content has a line right down the middle, or a separation. Hard to describe it. It shows up whenever there is sudden movement in the videos. Still or barely moving things do not cause it. When it happens it's a straight line horizontally down the middle of the video. Don't think it's my VCR. Is this an interlacing issue? Should/can I do anything about it?

Thanks.

Post a screen capture.

Post a screen capture.

That will be a challenge. Stepping thru the video in Sony Vegas doesn't show it. I see it in WMP when it's output on the TV display, however any screen caps I catch happens on my other PC monitor. The PC monitor is outputting to dark to show it. When you pause it doesn't show either. Just during play.

"horizontally down the middle"

Do you mean "vertically down the middle", or "horizontally across the middle". It can't be both!

If it's vertical, no idea.

If it's horizontal, it's your video card hitting a frame change half way through a frame - i.e. the frame of the source video are changing mid-way through the frames being sent to your monitor.

Try ReClock, and/or PowerStrip, and/or a different player etc.

Cheers,

Thanks for the reply. Sorry for the quick text. Didn't read what I wrote. It is horizontally across the middle. I was assuming this was interlace artifacts and was planning on converting it to Progressive, however will try as you suggest and see if it helps.

No, interlacing artifacts usually show up in more than one place. It sounds like you are getting a sort of shearing effect which is probably the graphics card as 2Bdecided suggested.

What specifically about the graphic card itself would cause this? I have a high end XFX 8800 GTS card with 640 megs rams. It is overclocked, however is stable with no artifacts in load tests.

You have the latest drivers correct?
What size display are you using? Sometimes very large displays have issues when rendering video, sometimes do to dual dvi input.

However, I am not exactly sure what could be causing this, as I am not a video card expert. Just answer the questions above and we will see if someone else knows.

It is being displayed on my standard definition 32" TV from an S-Video out.

Can you suggest another player? I try to limit what I install on my PC so do not have any DVD Player software or anything installed to test with. I was able to capture the screen at a point where it was showing a line down the middle heavily, however strangely enough, the line doesn't show on the screen capture.

I think it's a WMP thing specifically as although it's slow playing the video thru Vegas itself, it doesn't show those lines with the jerky recompression play mode it does.

Sorry, I don't have any good suggestions. I found ReClock and PowerStrip when trying to fix this problem myself, but as they weren't compatable with my graphics card and monitor, I gave up.
