jerky video ( sorry, couldnt think of a better say it ! )

Hi,

My setup is a follows...

AMD XP 2200+
Gigabyte GA7-VAX mobo
512Mb PC2100 RAM
Abit GeForce 4 Ti200
Audigy player PCI soundcard
1 x 60Gb disk
1 x 10Gb disk

DV Camcorders -
Sharp VL-PD3 ( NTSC )
Panasonic NV-DS65 ( PAL )

Its a generalist setup, not overclocked, mainly used for typical household stuff and gaming.

I'm trying to capture from the Sharp, and have tried using Ulead Video Studio 4.0, Windows movie maker, and a couple of other programs. The problem is always the same.

The capture works, but the resulting playback is seriously jerky... Imagine one of those early black and white movies from the early days of cinema, and thats what I get. The playback from the original cassette is fine, but as soon as I try to get it on the PC, jerk-o-vision... Its not unwatchable, just distracting, and as I'm trying to convert these from NTSC to PAL, it would be nice to get a quality capture. When I subsequently write to another DV tape on the Panasonic, the problem is the same. I thought that all I was doing was copying digital data from the camera to the PC, and the quality should be the same... Doh !

The Panasonic has a similar problem, but not as pronounced... Maybe its just that the piece of video I have on that doesnt show it so well....
Is it that the Audigy card is no good for capture ? I cant think of anything else...

Thanks in advance for any suggestions.

Mark.

What program are you using to view your video? Video Studio has a hard time viewing my videos without jerky playback, but WinDVD and PowerDVD say "bring it on!"! Since you have not re-encoded the captured video, I seriously doubt if anything is wrong with your video. Try a different software player other than Windows Movie Maker or Video Studio 4.0 (looks like you may want an upgrade for VS 4.0), and see if the problem remains. Hope this helps!

This jerkiness is called by interlacing. PowerDVD de-interlaces upon playback which means that you will not see it when you watch it on your computer. If your goal is DVD or exporting back to DV, these interlacing effects should not worry you as most TV are interlaced.
