Anthony, you are right, the value was 456 but I wrote 454 - my mistake! And for my previous post, I didn't get that you was talking about theory... I was SURE you were asking me to REALLY upscale the picture to 768! Sorry! Still friends?

I appreciated also your explanation, but I love simple things...

So, if I need to resize any PAL picture (with an AR higher than 1:78) from 4:3 to 16:9, I just resize at 768 pixel height and crop 96 pixels from top and 96 pixels from bottom. Is that easy! ;-)

Maybe AviSynth takes some time more to resize my way, but I have no "difficult" math to remember, and find the exact crop needed... do you agree?

Still not sure to do the anamorphic conversion... "the less resize, the better", my grampa used to say :) but maybe he was wrong, he said that long time ago...

At the end, someone else has noted that the 1997 SE aspect ratio was NOT 2.35:1? Or it is, and only the german version is 2.24:1?
