Need help with PAL SVCD > PAL DVD using Avisynth/CCE 2.5

[Elbart0-]

Sorry if this has been asked a million times already but I couldn't find anything on the forum to help me. I can't for the live of me figure out the numbers for the best way to resize 480x576 and keep the aspect ratio. If someone would be kind enough to post a script I would really appreciate it. This is all I have so far

LoadPlugin("D:\mpeg2dec_dll\MPEG2DEC.dll")
MPEGSource("D:\SVCD2DVD\s02e04.d2v")
BicubicResize(720,576)
ResampleAudio(44100)

and I have no doubt made a mistake already. :rolleyes:

Thanks Elbart0.

EDIT: Forgot to say the SVCD is 4:3.

Hi.

First off, you should be using the updated DVD2AVI/MPEG2DEC3 combo - get it from http://www.avisynth.org/warpenterprises/ (it's called "decodefix100")

Also, if you're not alreading using it, upgrade to AviSynth 2.5.4 and replace ReSampleAudio(44100) with SSRC(44100) for higher quality.

Everything else looks OK, the aspect ratio is probably a setting in CCE. Scan around and see if you can set it to 4/3 somewhere.

New script:

LoadPlugin("D:\mpeg2dec_dll\MPEG2DEC3dg.dll")
MPEG2Source("D:\SVCD2DVD\s02e04.d2v")
BicubicResize(720,576)
SSRC(44100)

Thanks for your help Bogalvator.

BicubicResize without specified parameters (coefficients) defaults to thirds (0.333,0.333). Meaning: it softens/blurs the image. When upsizing and encoding at high bitrates you may not want to soften the image, and instead try at least neutral bicubic.

Example: BicubicResize(720,576,0.0,0.5)

If you want more sharpness see if LanczosResize looks good to you.

You also might want to look here (http://forum.doom9.org/showthread.php?s=&threadid=70734) and here (http://forum.doom9.org/showthread.php?s=&threadid=70916) as well.

Enjoy. :)

I assume the SSRC(44100) has to do with CCE since 44.1 kHz is not DVD standard...

Also, I'm not familiar with SVCD specs but for DVD the active region is 704x576. If you look at a DVD MPEG-2 stream in DVD2AVI you'll notice small vertical black bars - the're used to pad from 704 to 720.
If you don't see those bars after resizing your SVCD to 720 then you need to add them (the distortion is rather small, though) by

BicubicResize(704,576,0.0,0.5)
AddBorders(8,0,8,0)

As a final note, if you use DVD-Lab for authoring you can add the SVCD video stream to the assets list directly. The program will sort it out for you.
