a white band across captured video via virturaldub

[omnimax]

Hi, I tried to capture a video from my hi8 camera using msi gforce 4 ti4200 and virturaldub 1.5.4. The problem I have is I sometimes see a broad white band across my captured video but it is not on the preview. my question is why and how can I ensure that it doesn't happend again. Thanks.

That's normal for capturecards,use TMPGEnc "Clip frame" to remove or leave it because TV's clip about 12% around the borders.

Hi,

The broad white band is macrovision copy protection. When your capture card is fed a macrovision protected video signal, like all nVidia cards, it detects the macrovision in the signal and deliberately imposes the broad white stripe to prevent the capture.

The problem is that it happens with poor quality signals too. The board can mistake the poor quality signal as macrovision and BANG; big white stripe!

You have a number of options:

1. Install nVidia reference WDM Capture Driver v1.08. They forgot to put the macrovision protection in this particular version of the driver.
2. Buy a video stabilizer or a TBC to improve the video signal.
3. Use a different capture system that can more readily cope with poor quality sources. I personally like the Canopus ADVC-100.

I hope this helps.

Ian.
