1:2.35 -> 1:1.85 crop and resize

[leonb]

Hi

I have a 1:2.35 pal dvd movie that i want to convert to svcd. As you know, the black bars fill more than half of the tv screen of a normal 4:3 screen. I want to reduce this to look like if the movie was 1:1.85, so it still have black bars, just less.

I asume the avisynth script will look something like this:

crop(?,?,?,?)
BicubicResize(480,576,0,0.6)

Can someone please help me with the ??? ?

thanks

Search the internet for FitCD, the best tool to resize and calculating bitrate for SVCD.

Hi there,

as frank already mentioned FitCD is really good for that but also very complex - but if you want to do it manually then here it is:

#PAL non-anamorphic (letterboxed) DVD 2.35:1 -> 1.85:1
...
Crop(90,72,540,432)
BicubicResize(480,576,0.00,0.60)
...

# PAL anamorphic DVD 2.35:1 -> 1.85:1
...
Crop(90,0,540,576)
SimpleResize(480,576)
...

HTH,
Gerti

If it is letterboxed, then I have a better/faster method than the one of gerti67. This is what you should write (you may change the 326 to the value you find after cropping, it should be always divisible by 2):

crop(90,125,540,326)
BicubicResize(480,432,0,1.0)
AddBorders(0,72,0,72)

As for the anamorphic solution, as gerti said, use SimpleResize (or BilinearResize), but DON'T use Bicubic, since you're resizing in only one direction, Bicubic won't improve anything, it will just waste time!

Hi

I understand the non-anamorphic solution:

crop(90,125,540,326)
BicubicResize(480,432,0,1.0)
AddBorders(0,72,0,72)


My dvd-player cannot handle anamorphic svcd, so the black bars must be part of the encode.

If I have an anamorphic source that is 1:2.35, and I want to watch it on a 4:3 tv and want it to look like a 1:1.85 letterboxed movie, shouldn't I also use the " AddBorders(0,72,0,72)" command? To what resolution do I resize after I have cropped to "Crop(90,0,540,576")? Also 480X432 ? Must I now use bicubicresize?

Thanks

Sorry, just after I asked the question, I relized that in a anamorphic 1:2.35 movie some of the black bars is part of the encode. So I need not add any borders.
