Had a simular problem. I'm using composite capture on ATI board at ATI YUV9[indeo]. Then render in Indeo 5.06 Avi format at 30fps, kb rate of 4000, no progressive scan. Play back is smooth and clean. The file can be huge. 450 megs for 8 minutes. Any other rendering or capture lost either quality or smooth playback. Especially non compressed avi for DV output.
Hope this helps. Windows 98se, 512 Ram, 40 gig 7200, 10 gig 5400, 500 amdk6 mmx

You didn't mention how you are capturing. Are you using a DV capture
through firewire? What capture software are you using?

I am having a similar problem, but I have specific details to add which may or may not reflect the original poster's scenario.

System: PIII 850, 384 MB RAM, Windows XP Professional, two hard drives dedicated solely to video. Maxtor UDMA 40 and 20 GB drives. Sony DCR-TRV120. VF 2.0a, VC 2.5a

I have captured about 140 minutes of footage from three Digital 8 tapes over 1394. They were brought in as a total of six clips.

I have gathered my clips together into one VF file and have started editing. I am noticing choppiness in the VF preview window, as well as in rendered files.

The thing is that when I look at the source clips in Windows Media Player, they are smooth as silk. It is only once they get into VF that they start showing signs of choppiness.

I tried bringing one clip which had choppiness problems into a new project alone. It looked fine both in VF and in WMP after rendering back to DV format. I have triple checked that I have isolated the event in the original project and that there is nothing going on that should cause it to print back to tape as anything other than an exact duplicate (no recompression).

So what's going on here?

Thanks.

I have learned that for some reason, a clip that is showing choppiness or jerkiness in the preview window (and when rendered) can be "fixed." By deleting all events that use the clip and putting the clip back in the project, I solved the problem. Now the question remains what is causing it? And how can this behavior be prevented, as this workaround may involve destroying a lot of work? I'm thinking bug that needs to be addressed by SF.
