Hi guys,

Firstly, thanks to all the help provided by all those contributing to this thread: http://forum.doom9.org/showthread.php?s=&threadid=27570

I seem to have gotten the problem of "Not a valid dvd2avi project" sorted out after trying everything from these threads ;)

Finally I can encode again, so setup everything for a divx 5.02 (pro)job as directed in the guide, and although no errors were reported during the encodng, the end result movie has a major flaw:

The picture appears to have been "shifted" to the left. Resulting in the bit that went offscreen to the left to reappear on the right side of the screen, seperated by a black bar ;(

Here is a pic to illustrate as this is kinda hard to explain: http://www.sputnik.za.net/test/split.jpg

Here follows my d2v project file minus all comments:
(NB: I had to move the crop before the BicubicResize, or else I get an error from VirtualDub stating access violation! If this is the cause of the problem, then I'm screwed, cos it's the only way I can get the jobs to run in virtualdub...)

--------------
LoadPlugin("F:\PROGRA~1\GORDIA~1\mpeg2dec.dll")
LoadPlugin("F:\PROGRA~1\GORDIA~1\decomb.dll")
LoadPlugin("D:\WINDOWS\System32\vobsub.dll")
mpeg2source("F:\esca-extras\esca_xp.d2v")
Telecide()
Decimate(cycle=5)
BicubicResize(640,480,0,0.5)
crop(8,0,700,478)
VobSub("F:\esca-extras\vts_17_0")
--------------

Any help/suggestions appreciated as always.

I don't know the history of your previous problems; nor can I help you with failures of vdub.

But I believe you've picked out the reason for this particular problem, you are cropping a 640x480 frame with values that made sense only when it was 720x480. No wonder you got invalid results.

For future reference: you can preview an avs in virtual dub or any avi player, prior to doing any encoding. That way, if you see something like this again, you won't waste time encoding it.

@ snake-boy:

It seems that there's a problem in your avs script. Crop command should come first before resize command.

Hope this will solve your problem. ;)
