movie not fluid after authoring

[aldebaran]

Hello,
I'm newcomer to this forum and to DVD world, so be patient if this question is a trivial one. :D

I'm putting old home made movies made in VHS on DVD (PAL)
process is: Tape to DVD via DVD recorder set; DVDShrink to get VOB files; AVISynth scripts feeding Adobe Premiere via AVS Plugin.

I use Premiere because I want insert transitions between movies chunks.

All this works fine, but after authoring with DVD-lab I noticed that movie is not fluid expecially when scene consists of quick horizontal movements. I get same effect both seeing DVD on DVD set and using PowerDVD on PC.

Advancing using the 'frame by frame' option of PowerDVD shows that movements are a sort of one step forward and half step back, giving so the impression of not fluid stuff. Here comes the (for me) strange thing: looking at VOB file (I used MPlayer and VirtualDub between others) this behaviour is not reproduced and video is ok.

Suspecting a DVD-Lab issue at this point I authored a test with Adobe Encore, but I got the same result!

Further testing I came to Cyberlink PowerDirector and with this DVD seems to be good (I've not burned the DVD, instead I've put it on HD, this for all the three tools I tested, as I think this doesn't matter).

I tried fiddling with DVD-Lab options to correct the problem, but I can't get the job

Any idea?

:thanks:

Sounds like a problem with the field order of your video. Make sure it stays the same all the way through your workflow.

Thanks MarcN, you put me on the right way.
Adding one line to avisynty script:

a=Mpeg2Source("K:\MyMovies\DGIndexOut\Virgy_2\VTS_10_1.d2v")
SeparateFields(a)
b=Directshowsource("K:\MyMovies\DGIndexOut\Virgy_2\VTS_10_1 T01 2_0ch 256Kbps DELAY -160ms.ac3")
Audiodub(a,b)
DelayAudio(-0.160)

and setting Premier export with Field order to upper did the right job.

BTW I still can't understand why opening the output of Premiere with other tools shows the movie in the correct way, whichever the field order is and why authoring with PowerDirector (but I prefer DVDLab and want to use this) the mpeg is ok.

Cheerio.
