2:35 to 1:85 when making SVCD

[herbapou]

Hi,

I want to convert my 2:35 DvD`s to 1:85 when making SVCD`s because I am kind of annoy with having half of my 4:3 tv with black bars. 1:85 are not so bad. I dont mind loosing a bit of the left/right picture of the 2:25 movie to make them 1:85

How can I do that?

And if I could find a way to make this with DVD2SVCD it would be great...

You can calculate the resizing with FitCD and edit the Avisynth script.
Example 1:2.35

BicubicResize(448,314,0,0.5,0,64,720,448)
AddBorders(16,129,16,133)

Example 1:1.85

BicubicResize(448,398,0,0.6,76,64,568,448)
AddBorders(16,81,16,97)

You will loose about 9% left and right

Here is the replies I got on Doom9 DVD2SVCD forum regarding this issue.

I have test the recommendations made by gerti67 and they work...


2.35:1 anamorphic (16:9) to 1.85:1 conversion...
---------------------------------------------------------------------------------


Hi herbapou,

you can actually do that in DVD2SVCD by editing the AviSynth script manually.

Start your conversion with DVD2SVCD as usual but make sure you have ticked the "Edit when dvd2avi processing is done" option in "Frameserver" tab before you hit the "Go!" button.

When the DVD2AVI processing is done a little window with the AviSynth script will appear. Edit and change it like this:

# SVCD PAL 2.35:1(1.85:1) anamorphic -> 16:9(4:3)
...
Crop(90,0,540,576) <= insert this line
SimpleResize(480,576) <= this line depends on the resize method
AddBorders(0,72,0,72) <= delete this line
...

# SVCD NTSC 2.35:1(1.85:1) anamorphic -> 16:9(4:3)
...
Crop(90,0,540,480) <= insert this line
SimpleResize(480,480) <= this line depends on the resize method
AddBorders(0,60,0,60) <= delete this line
...

Then hit the "OK" button of the AviSynth script window and the conversion process will continue as usual but you will end up with a 2.35:1(1.85:1) movie converted to 16:9(4:3) format.


2.35:1 letterbox (4:3) to 1.85:1 conversion:
---------------------------------------------------------------------------------

Hi herbapou,

for letterboxed movies with a 4:3 aspect ratio the script should be changed as follows:

# PAL 4:3 letterboxed
...
Crop(90,72,540,432)
BicubicResize(480,576,0.00,0.60)
...

# NTSC 4:3 letterboxed
...
Crop(90,60,540,360)
BicubicResize(480,480,0.00,0.60)
...

But be aware, with this the source gets stretched vertically too (from 432/360 pixels height to 576/480 pixels height) so it is recommended to use the BicubicResize method because the SimpleResize method is not really good in stretching and the Bilinear also but still better as the Simple one.

I thank Gerti for his help :)

How could I know, that you have a widescreen TV set?
You asked for 1:2.35 to 1:1.85 and I assumed you encode to 4:3 DAR.
All scripts, that you posted above are made for 1:2.35 to full screen (4:3 or 16:9 depending on the DAR). Also it ignores TV overscan, that is IMHO a bad idea at all.

[herbapou]

I do encode for 4:3 TV. I have a 4:3 TV.

The movies converted with those settings have a small black bar at top/bottom just like a regular 1:85 movie look on a 4:3 TV set. I think if you set the input aspect ratio to 4:3 (even if the movie dvd is 16:9 2:35:1) and apply those settings, you will end up with an anamorphic SVCD that would play full screen on a 16:9 TV. But I am not sure, making SVCD`s for 16:9 TV's with DVD2SVCD is pretty tricky...

BTW your settings didnt work so thats why I posted those in case other people would want to do that also. But it could be because they are PAL settings, I forgot to mention I use region 1 NTSC DvD`s sorry.

Your settings gave me a 1.85:0.5 movie with about half the height (aspect ratio screwed up). The other half was black with a green bar at bottom.
