Script For S/VCD To DVD ?

[Red Raven]

What would be a good script to convert s/vcd to dvd,keeping in mind best quality possible?

I'm using CCE SP 2.7 & Avisynth 2.5

Cheers!

directshowsource("C:\video.mpg")

Anything you can add to that Leo? -- i'm not much of an expert on
avisynth scripts :)

Few question;
How would i change AR?
Would i need to crop picture?
Can i improve picture quality?

:confused:

What kind of video do you have ? What resolution is there, are there any borders, is it noisy ? Post at least a screenshot or cut a short clip from it and upload somewhere... @ rapidshare (http://www.rapidshare.de)...

directshowsource("C:\video.mpg")
Should be better Mpeg2source("C:\DVD2AVI_Project_file.d2v")
Run your SVCD files through DGIndex and make a d2v file (project file). This file you can load in avisynth.
For the resizing:
Load the mpg file in VDubMod. Add filter nulltransform. Crop the black borders. Write down the values.
Load mpg in FitCD. Apply the values for cropping. Select the target. On the screen down left you will get ready to use avisynth script (except there is DirectShowSource and you need Mpeg2source.
Use Lanczosresize for resizing. You may try to improve the picture quality with some limited sharpener - then use LimitedSharpen (:) )function or also good is ModerateSharpen()(for this look removegrain thread)
Also good luck!<-- it is very important.

you'll probably want the SVCD deblocked...

try:

mpeg2source("blahblahblah.d2v",cpu=4) # if interlaced, add "ipp=true" as well.

you may want to leave the AR how it is and just resize it to 720 width. to do this, you have to bear in mind the fact that the 480 width assumes a frame width of 704x576/480 rather than 720x576/480. so do this:

lanczosresize(704,576).addborders(8,0,8,0) to get up to 720.

One more question;
Would the same script/process be used to load an mpeg1 from a VCD?

[Boulder]

For MPEG1, you must load the clip with DirectShowSource as Leo 69 posted earlier. You can deblock by using Deblock() or BlindPP(CPU=4), both are in the latest dgdecode.dll. Use FitCD to get the correct resizing parameters if you are unsure.

Mpeg1 from standart VCD (352x288/240) is DVD compliant (except the audio must be 48K). So for DVD you don't need to reencode the video.

I don't think this is correct. For correct aspect ratio from SVCD to DVD just resize the 480 width directly to 720:

lanczosresize(720,576)

See capture guide:

Section 5.2.1 Sample rates of some standard formats

The table say that the SVCD width corresponds to 53.333 µs sampled with 480 pixels, and DVD with width of 720 pixels do also correspond to 53.333 µs. If this is true then 480 pixels width of SVCD should be resampled to 720 pixels width of DVD when converting SVCD to full DVD resolution. After this resampling you can crop 8 pixels left and right if you want a DVD with 704 pixels width.
