PAL/NTSC heigth conversion.

[Linux]

If am am not not totally wrong an american TV-set (NTSC) and a european (PAL) both have the same proportions between heigth and width. In other treads there have been discussions about converting between PAL and NTSC. The lines in the PAL picture should be converted into NTSC by compressing it (Bilinear). The same way conversion from NTSC to PAL should be by stretch it (Bicubic).

If the conversion is done by adding borders or cropping borders this makes the aspect wrong.

The only way it would be right to add borders in a NTSC to PAL conversion would be if an PAL TV where heigher than an NTSC TV.

For me as an owner of equipment that can view both (primary PAL) I allways make the encoding of a NTSC movie to an NTSC SVCD.

Hi linux,

you're fully right.
I was thinking of the computer picture which does not change the spacing between the lines. But the aspect ration of the TV doesn't change ... so it's true to resize the picture.

Tried this and it worked just fine.
The audio conversion works either. But i cannot implement it into dvd2svcd. For the audio i can place a batch file, but not for video. So it's up to dvd2svcd to implement it. That would be my hope of restoring the real movie from a PAL DVD.

Thanks for the point
