Need help troubleshooting video capture

[scorpio47]

Hello all - I used to do a lot of conversion to DVD, but haven't done so in awhile. My set up is as follows: Windows XP, 2.99Ghz machine, 1 GB of RAM. My capture is a Canopus ADVC100, and I'm capturing from a SVHS via S-Video. When I output the video straight to a TV, the video looks okay (well at least what you could expect from an old VHS tape). When I hook it up to the Canopus box and run it through Windows Movie Maker, the video jumps like crazy, almost like the tracking on the VHS side is off, but I double checked and again, piped directly into the TV, it looks fine. I tried connecting a miniDV camera directly up to the firewire port and any movement has that same video skipping issue. I tried a couple of different firewire cables and also tried a different port. Anyone encounter something similar before? Any ideas?

Could the ADVC unit be set to PAL and be having problems with NTSC input ?

Does it only affect movement ?

Can you post a few seconds of footage showing the problem ?

It could be field related, but that would unusual prior to editing.

No, it's set to NTSC

Yes, if it's a relatively still frame it looks okay

I'll post a sample, but should I post it in the uncompressed DV-AVI or should I compress it with divx?

DV AVI. Only need a few second of motion

Try to capture with WinDV. Then play with WMP or VLC. That will separate Windows Movie Maker issues.

I've never seen the symptoms you describe.

Okay, now I'm really stumped, but the problem seems to be solved. The machine I'm posting this from is different from the machine I'm capturing from. When I play back on the capture machine, it's a jumpy file, but when I put it on this machine it's not, it looks absolutely fine. Very weird...different monitors though, but I don't seem to have a problem with other video, just DV-AVI on that machine...well, whatever the case, it seems to be okay. Thanks for your suggestions

My guess is you are using a single drive. Best to capture and play to/from a second non-OS drive. A fragmented or nearly full drive can also play jumpy as the disk seeks over widely spaced clusters. Another possibility is background disk activity.
