Jittery Images in VS 10

[ranazarian]

Please Help

VS 10 SP1 XP SP2 Intel Pentium D 2GHZ 2GB DDR 100 GB HD

I have about a 20 minute video with a mix of high res digital pictures and digital video from DVD's (mpg) and video cameras (AVI). This project was fine until a couple of days ago, but now it has really distracting jitter - most noticeable in the still images. The images show up clearly, then as they hold on the screen the pixels seem to jitter or flicker. I have always used field based (lower field first) I imported the videos in AVI and am outputting in MPG. Seems to have the same problem with both MPG-1 and MPG-2. I'm not sure, but it seems to be also taking much longer to render out. Any help anyone can give me would be greatly appreciated as I have only a couple days to finish and my once perfect video now looks pretty crappy.

Ranazarian,
I assume that you have dropped AVI(DV) and Mpeg2 source files into the Video Studio Timeline, along with jpeg still images and have created a DVD-Compliant video file.

What did you do in the computer a few days ago when it was working fine?
How are you playing back the video file when it jitters?
Are you sure of the Field Order in your source video files?
Please list the properties of the two source video files and the properties of the DVD-Compliant video file.

Mpeg1 is substandard resolution and not important as a debugging aid.

well I don't think I changed anything in the computer from when it was working. I did have a MS office patch installed - that seems like a remote possibility. So perhaps reinstall of VS would help.

Playback is in Windows media player - which is what I've always used to check stuff before making dvds

I believe field order is correct from source files. Would that impact the still jpegs? The imported AVI files look just fine.

Hope I'm answering your questions. Thanks for the help

upon examination of the video out - the video starts with about 2 minutes of stills that are just fine, then the MPGs and AVI's start and they seem to jitter as do all the subsequent stills. So is it possible that I inserted an clip with a wrong field order or something and that screwed up everything after it? As you can tell, I'm not exactly expert. I have at least 3 different video sources, so it's possible they aren't all the same field format.

Right click on each file in the timeline to check the Field Order in Properties.

I think that's it. They are all upper field first (I think I might have said lower) except for 1. I think everything after that 1 is messed up. I can delete that clip and see if it fixes it. Is there a quick way to convert the clip?

[jchunter]

Sure, just delete the video clip that is different, save the project with a new name, then Share/Create Video file and set up Upper Field First. If that video clip is expendable, you should be able to burn a good DVD.

You can convert the maveric field order clip to the opposite field order but you will definitely reduce its quality.

Thanks to all with input - but I'm apparently not out of the woods yet. Despite using only clips with all the same frame relationship (upper first) I have the same problem. I can see the improvement in my video clips, but my stills and clips have a dramatic quivery jitter. Still looking for suggestions.
