VV3c DV to NTSC DVD MPEG-2 problem

Hello, i recently finish editing this video i was working on in Vegas Video 3. I set it up to render as an MPEG-2 compliant DVD and set it to encode overnight. next day when it was done and i looked at it the picture had these lines (interlaced looking i guess) distorting the picture as more heavy movement happened. My question is , are there any particular setting to change it to that will result in a nice conversion? i had use the default DVD settings and would like to know what to change it to. someone told me that it could be a field order issue, but dont know how to fix it. Any help would be Greatly appreciated. Thanks a lot.

Did you use the "default" template, or the "DVD-NTSC" setting. At default you're averaging only 4000vbr, at the DVD-NTSC you're averaging 6000vbr. I've done render tests at both average bitrates and found the 6000 almost indistinguisable from the original. With 6000 you should get anywhere from an hour and 15 minutes to an hour and a half on one DVD.

If it's field order problem it wouldn't show up on your computer monitor but it would on your TV set as this is interlaced.

I did have a Vegas project where I loaded several clips (all captured from the same source DV camera which should be lower field first) & when this was rendered to MPEG & burned to DVD I got jittery effect but only at a few places in the movie , not consistantly all the way through. I went back to the Vegas project and examined the clips in the media pool. As I've said all the clips should have been lower field first as they were from the same DV camera captured through firewire, but unexplainably some were shown as upper field first & it was these clips that were giving problems on playback in DVD. I right clicked on each of these in the media pool and changed the properties to lower field first. re-rendered & burnt , playback now fine.

If you are seeing this jittery action on TV playback but not computer monitor then field order of clips is where I'd start. If it's DV source through firewire it should be lower field first, If analog then it will depend on the capture device but if they were all from the same source they should be the same anyway.

I had similar questions about Mpeg2 giving me flashing and jerky playback in VV3.0 and also could not get smooth play on windows media player. I had never burned a DVD disk and was asking and reading tons on this. Got good feedback, but SoFo said, "just try it", so I did. I burned my first DVD testing three short NTSC DVD tests that were "bad". All looked beautiful on DVD. So, maybe that is where you are also. I couldn't tell what you were viewing with. Hope it is that simple for you and me in the future. Never did find out why the jerky views on the pc playback of the mpeg2. Don't really care at this point for my situation.

Well i was a DV source, i preview in windows media player and the picture kinda distorts with horitals lines...anyone have any idea why...im a little leary to waste a DVD to just try it and all. i find it odd, if anyone knows it waould be great to know. Thanks.
