large white stripe across the screen when capturing analogue

[soodesh]

Has anyone ever encounter this problem?
I get a large white stripe across the screen when I try to capture analogue video from a vcr using ulead videostudio 5.
I have no problem capturing from dv source.
I appreciate any help/advice.
thanx.

What capture card/drivers are you using?

I had a similar sounding problem canpturing with my ASUS V7700 deluxe (ie GForce2 GTS card) card and the nVidia 1.11 wdm capture drivers under win98SE and using any capture programs. Going back to the 1.08 drivers fixed the problem.

(For what it is worth, I have completely given up on the wdm drivers now, as the vfw (asuscap.drv) drivers gave me a much better picture. The wdm drivers caused a lot of colour distortion ... even visible variations in colour between two 'adjacent' lines from 2 fields in a frame!...but I blame Microsoft, not nVidia...I suspect it is either msyuv.dll or vfwwdm.* )

But maybe it is something else for you!

My video cature card is nvidia geforce3 Ti and the driver was pre-loaded when I bought the computer. I am not too sure which driver it is. But I don't have any problem when I capture/edit/render from a DV source.These white marks/stripes only occur when I try to capture from an analogue source.

Where is the stripe ? If it is along the very bottom or edge then that is normal.

In my case, the stripe is in the middle, and takes up nearly half the screen (so, no, it's not head swithing noise etc.). It's also impossible to live with.

Hi all,

I'm not sure what type of video feed you have, you say it's capturing from a VCR, is it possible that the feed is macrovision, (copy protection), encoded. The ATI all in one reacts in a very bad way to this unless you have a macrovision decoder/picture stabiliser box inbetween the VCR and the card, is it possible you're having the same problem.

If so I'd suspect the new driver switches on the Cards detection of macrovision whereas the old one doesn't. If this is the problem you're being affected by Picture Stripe, Macrovisions particularly nasty copy protection, the old version just used to play around with sync pulses wheras picture stripe inverts the luma signal across the middle of the screen.

I don't know if this is of any help just an observation.

Sorry, no macrovision on my camcorder!

Don't know about soodesh though, maybe it is his problem

My apologies Triffid,

I didn't read the specifics of your problem, no that doesn't look like Macrovision, (although the way legislation is being bandied around camcorders will probably have to have Macrovision by the end of the year

hi all,
thanks for all your advice/comments. Just to let you know I have no macrovision on my camcorder/vcr. And also these white bands are exactly as triffid mentioned earlier: it takes about half the screen.
thanks again.

I had a problem with a white line that would scrool up my screen. turned out my receiver was causing the problem. Once I moved it the line stopped.
