How to remove noise on images acquire from Digital 8 VCR to PCI-1409 frame grabber ?

[FraserD]

I have some constant noise in the form of a discontinuous white horizontal line running accross the top of images which were grabbed from a digital 8 video signal. I have tried all the settings in MAX to remove these and have check the integrity of my connections, but to no avail ?

This is something I haven't seen yet with a 1409. Chances are that this noise is coming from your camera, but do you have another source that we could use to check? If the white bar is at the top of the image, then you may just want to adjust the acquisition window to ignore that region.

Please let me know if other cameras give the same behavior.

Kyle,

I found that adjusting the acqu window did the trick.

It seems that all the video i have on Digital 8 tapes gives me the same problem. When i use the camera directly to the frame grabber there is no problem.

In due course i'll try another camera with the Dig 8 VCR and compare these output picture quality.

Thanks for the advice,

Fraser
