Hi,

How is the output to a TV? You'll notice venetian blinds on a VGA monitor - interlaced video - that you won't see on a TV.

If the "stair steps" are vastly bad and there is pronounced flashing, it could be the wrong field first.

BTW, if you want to use DV video for the web, just deinterlace the final out put.

Output is to a SVGA monitor which is what I have to use during the capture and edit process. I will check if it occurs on TV by burning a small file to cd and playing it.Thanks.

SUCCESS.... despite the ventian blind effect on captured file it does not appear when file is rendered to CD and played to TV or PC. Like you say could be to do with interlacing or maybe capture setting.Thanks.

I'm having a similar problem with horizontal banding, but it's on my final output to DVD. The banding/stairstepping is very bad when viewing the DVD on TV.

I've been using Video Studio 8 for a few months, but this problem just started to show up.

The problem does not occur throughout the whole DVD. It's only in places where I've used a logo graphic that I created in Photoshop, or in flash animations that I rendered to AVI.

These graphics/animations have rendered perfectly up until the last few days.

Any ideas?

Any ideas?

It is probably the resolution of the graphics. They should be the same as the system, NTSC or PAL.

I found the problem: I had RESAMPLING QUALITY set to Good instead of Best. When I reset it to Best, the problem disappeared.

Thanks
