DVD problems with Old Files - HELP!!

Okay ...

Just got our BLAZING-FAST new systems set-up (Win XP, 3.06 GHz, S-ATA, etc.) to run V4. At first blush, I was thrilled!

The first project I edited (DV-captured video, edited & finished in V4) and burned to DVD-R went very well. (A minor artifact issue on a few of the layering effects, but that's another thread ... see "sparks" thread to help me with that!)

I decided to convert some of my old analog (M-JPEG edited) files over to MPEG-2 using V4, so I could burn/archive them to DVD.

AAAAHHHHHHH!!! Problems!

The conversion & render seemed to go fine, and when I view them ON THE PC as MPEG-2 files, they look fine. When I burn to DVD, and WATCH on the PC, they still look okay. When I watch the SAME DISC on a stand-alone player (connected to a normal TV) I get the weirdest "ghosty-trails" (sort of looks like the "mouse-trails" you can turn on in Windoze if you have trouble following your pointer) whenever anything moves! (non-moving subjects look fine) What is the deal????

I tried taking one of these old projects FROM TAPE, and capturing through the DV cam, then rendering out to MPEG-2, burning to DVD, etc. SAME PROBLEM - not quite as bad, but still there.

Since the video looks fine on the PC-monitor, but has the "ghost-trails" on an analog TV, I am suspecting this is some sort of "interlacing/field-order" issue? (BTW, the projects were originally produced in Ulead MSP.)

I am not sure even where to START looking for a solution. I am a producer/editor (from the bad old analog days) and "tweaking codecs" is NOT my forte'.

If anybody has any insight into this problem, I would LOVE to hear it ... especially any similar stories.

BTW - Overall, I LOVE working in Vegas! I got accidentally hooked three months ago when I decided to give it a whirl for a test project, and now I am a TOTAL CONVERT!

PLEASE HELP! I've got bounties to chase!

Just a guess...

If your source files are MPEG and you edit and recompress to MPEG again some of the frames are going to be mushy (my term) because of the compression on compression and while you may not notice when playing off a computer, once you view on a TV where the frame is stretched out to fill the screen some action scenes may have some ghosting.

Not a heck of a lot you can do. Depends on the source file. I'll assume you tried the reduce interlace flicker switch and you haven't disabled resample if you've done any speed changes or added velocity envelopes.

A couple new things to fiddle with in version 4. You can try a supersample and/or adjusting the envelope for motion blur. SPOT has a tutorial on his site. It can work wonders and really improve otherwise low quality scenes and it may help with your problem, haven't done it yet for that myself. Just be aware doing supersample will REALLY increase render times especailly if you do a large section at a high value. So only apply to the sections that really need it, otherwise drop the envelope all the way to zero, otherwise you'll still be rendering the same project a week from now.

Did you try changing the field-order?

Sure sounds like a field order issue to me. Try doing the same thing with "Upper Frame First."
