DVD -=> Micro DVD via DVD2SVCD

[j77]

I couldnt decide to which forum to post this (dvd2svcd advanced/newbie or mcrodvd but I decided this one since I consider myself a newbie with the DVD2SVCD - only been using it 3-4days) :D


DVD -=> Micro DVD via DVD2SVCD
-------------------------------

For a more automated procedure, one can use the DVD2SVCD software by

1. Editing the Avisynth File to a resolution compatible with the DVD
specifications
2. Using 48Khz not (not checking the Audio Downsampling)
3. Using the files created by DVD2SVCD in a DVD authoring software.

There is no need for CD Image Creation

The only problem I have come across so far are the burnt in subtitles.
If the resolution chosen is much smaller than that of the
SVCD 480x576 that DVD2SVCD assumes, then the subtitles might wrap
around to the next line.

I am sure there is a perfectly simple solution to this, but I have to study
for my Pathology II exam in two weeks' time and I cannot spend any more time
on this idea that I had. (already lost many days' worth of studying)

In the way that I have mentioned above, it is quite obvious that
DVD2SVCD can be very easily implemented with few new features
(resolution selection and subtitle positioning) and become
DVD2microDVD as well....

I had to resort to this way of doing it b/c CCE would always crash when I
would drag/drop or add an .avs file made in the way the Doom Guides describe.

PS thinking in Divx: encoding with the big black areas should affect the quality of the output video. Has anyone thought that maybe it would be better to encode the video and then add the black strips? (I know what sounds simple isnt always easy)

Thanks for your attention! :p

Since DVD-size D1 (720x576) is larger than 480x576 I believe you had half-D1 (352x576) in mind.

The black area had been discussed elsewhere but a short rerun.
A black macroblock (16x16) is extremely well compressed. So if your border in any side of the movie is absolute black and dividable with 16 you can forget them altogether.
To make them absolute black if the source is not “clean” edit the Avisynth script to first cut away the black and then add it back.

The following resize from D1 to half-D1 without changing aspect ratio.
BilinearResize(8,0,704,576,352,576)
As you see you loose a total of 16 pixels on the sides to keep the aspect.

The same while cutting and adding 32 pixels from top and bottom of D1 with resize between to make black borders “really” black.
