strange interlaced material or wrong decoder or what?

[galocza]

hi,
im creating a dvd from our february skiing vacation (yeah, im a little late 8), and i will to put it in a star wars theme, and id like include some fan made movies into the dvd as easter eggs.
now i have a problem with a movie called duality (you might remember that one). when playing it it just plays fine (i use mpc), but when its loaded into vdub or served into an avisynth script the motion gets jerky (one big move forth a smaller back, i cant explain it better). as my avisynth script isnt correct, i cant convert it to mpeg2 properly.
as im from pal region i dont have much experience with deinterlacing (and im not sure that its something like that) but in the past i could resolve those issues with Donald Grafts decomb, and its included "deinterlacing for dummies" guide. not now, however, and im not really sure whether this is the problem, as the movie played on mpc is just fine...
properties (vdub):
name: duality.divx (yeah, one of those...)
resolution: 640*272
fourcc: DIVX (opendivx, divx4.0 and later)
decompressor: xvid mpeg-4 codec

should i try another decompressor? or its some interlacing issue?

thanks in advance,
g

Moving to AviSynth Usage forum.

Yes, I know the entire thing is available freely on the internet, but you might consider posting a link to a small fragment for analysis.

Try adding a ComplementParity() call in your script.

If that doesn't help, post a small *unprocessed source* clip (use VirtualDub, select a range, and direct stream copy), and give us a link to it. Also, post your exact script.

thanks for your quick reply
the script is now (as it didnt work i #ed every line except for avisource):
avisource("f:\z\media\swfan\duality\duality.divx")
#BilinearResize(352,304)
#AddBorders(0,136,0,136)
#KillAudio()
#Info()

a small (a few frames) sample is here:

ps: i tried complementparity but no change

edit: but i dont think the problem is avisynth related, the original movie loaded into vdub does the same.

the video runs flawlessly here.
I use ffdshow for decoding at playback.

Probably your XViD / DivX decoder Filters are too old.

yes, it plays just fine. but try to load it into vdub, and watch it by frame.
anyway, you are right its decoder problem: i uninstalled my old 1.0.1 xvid and installed the latest stable from Koepis site. now not every second, only 6th? 7th? goes 'backwards'.
it would be helpful if you tried it in vdub, and if its ok youd write me which decoder do you use for decoding (in vdub, file information/decompressor).
thanks,

well,
i still dont know what was the problem, but a solution is here if anybody comes across a similar one: i uninstalled xvid (i tried nics and koepis latest un/stable, all i could find - none worked) and installed divx play bundle again, the first time in years...
well, this worked, i dont know if this is a bug or some native incompability between (older) divx and xvid.
thank you all who tried to help me,
