If you work in VCD that want to say that your player does not handle VBR MPEG1 so well.

its not VCD it was a avi to KDVD, I have played vcds, kvcds, kdvds on my dvd player all play fine so I'm a litte cofused to whats wrong.

I used optimal script and these two lines are the only difference:
  • AVISource("C:\movie.avi")
    converttoYV12()

is this right?

andybno1,

could it be interlaced or ivtc ?
when was encoding dumbo (Disney) was needed redo using
Telecide(order=1,guide=1,post=2,vthresh=30)
to remove seamless moviments !

but i did skvcd (480x480), don't know if Kdvd need something like this !

take a look in the ink's thread "Interlaced / Progressive ... "

It is better if you configure codecs (DivX and XviD) than using converttoYV12(). You can read about this beginning here
Did you encode it as usual?

Sorry, I was talking about your mpg encode. You encode it as usual? Same resolution, same encoder, same script, or change any setting that could be cause of your problem?

well the avi file is: 592X320 and NTSC

encoded to KDVD PAL 720X576 (anamorphic)

and script I used was:

Code:
##Main section and static filters ###
#
AVISource("C:\movie.avi")
converttoYV12()
#
undot()
asharp(1, 4)
GripCrop(720, 576)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(1.5))
MergeLuma(blur(0.1))
#
#

##Linear Motion Adaptive Filtering ##
#
#( Portions from AviSynth's manual )
#This will apply variable temporalsoften
#and variable blur.
#Both filters are active at all times, and work inversely proportional to the
#activity, measured from current frame to next frame.

ScriptClip(" nf = YDifferenceToNext()" +chr(13)+ "unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100))).TemporalSoften( fmin( round(2/nf), 6), round(1/nf), round(3/nf), 1, 1) "
#
#
#

GripBorders()
#LetterBox( Your_Values_Here )#Depends on situation. Use MovieStacker!

#
#
##Functions ###

function fmin( int f1, int f2){
  return ( f1<f2 )? f1 : f2
}

#
####

Taking this in mind and looking at the script I would say it is a frame rate problem

The best is to NOT convert. Did you ever try to give NTSC KDVD to your player ?

Else just add "assumefps(25)" at the end of your script and don't forgot to use the correct setting in besweet to convert also your audio form 23.976 to 25.

Note: you source is 23.97, right ? or is it 29.970?
