Aspect Ration Problems

[icemanatvcd]

I have made a PAL DVD (16:9) conversion using these steps

1. Smart Ripper to rip DVD.
2. DVD2AVI to save the project file.
3. VFAPI Converter to make a "fake" . file
4. TMPGEnc. to convert the audio using external Toolame.exe
5. AVISynth. an .avs script opening the .avs file created by VFAPI convertor and adding the following lines:

AVISource(“C:\abcd_vfapi.avi”)
BicubicResize(480,576)

6. CCE 2.5 to encode the .avs file using 4 passes.
7. Multiplexing using bbMPEG (the AVI2MPG2.exe).

The problem is that finished .mpg files are stretched when I play those files using WINDVD through playlist command. Also the picture is little jerky.

What have I done wron? How can I correct this problem in particular the aspect ratio problem.

Thanking you in advance.

AVISource(“C:\abcd_vfapi.avi”)
BicubicResize(480,432)
AddBorders(0,72,0,72)

Even better: Install the latest Avisynth and the MPEG2DEC plugin (I recommend the latest, modified by dividee). Then you don't need to use VFAPI.

LoadPlugin("C:\full path\MPEG2DEC.dll")
mpeg2source("D:\full path\abcd.d2v")
BicubicResize(480,432)
AddBorders(0,72,0,72)
or
LoadPlugin("C:\full path\MPEG2DEC.dll")
mpeg2source("D:\full path\abcd.d2v")
Crop(0,72,720,432)
BicubicResize(480,320)
AddBorders(0,128,0,128)

icemanatvcd, I remember you have a widescreen TV and don't want to add borders. So although the picture is stretched when you play those files using WINDVD, the TV should display the correct aspect ratio.
btw, you can change the displayed aspect ratio of WinDVD.
P.S. My head is clear now

Thanks for that Truman as they say in Australia here, you are a legend! I will try this, that means encoding with CCE 2.5 for another 25 hours! Great! I might as well use DVD2SVCD. You are right I have a wide screen TV but some times I watch them on my PC so others can sleep! I tried changing the ratio on WINDVD still did not make any difference. I Will try your method though.

Thanks once again.

Just one more questions Truman, what is the difference between
AddBorders(0,72,0,72) and
AddBorders(0,128,0,12

Thanks in advance.

I suggest to use a short (5 minutes?) clip to have some tests.

The difference is, that I cropped the borders of the source file using the 2nd script. That's why I have to add larger borders afterwards. When I crop before encoding, I get a slight speed increase.

72+432+72=576
128+320+128=576
