Apple Compressor 16:9 framesize ?
on Oct 17, 2008 at 2:48:29 pm

i'm a bit confused about 16:9 framesizes.

my dvpal file is 720x576 anamorphic.
when I use Compressor to convert it to MPEG2 16:9, the file is 720x404. I lose pixels.
shouldn't it still be 720x576 pixels (and afterwords stretched in the dvd or whatever-player) ?

Compression documentation doesn't make this quite clear for me, so I hope someone could tell me how it works :) thanks!

The trick is to not believe what QT is telling you. It looks at the PAR flags and says it's 720x404 when in fact it's 720x480 anamorphic. Look at it through MPEGStreamclip (a free app if you don't have it), and it will show you that it's correct.

Actually it would be 720x576 if you use the (superior) PAL format rather than the 720x480 of NTSC.

Yes, that's true, but same point, same result. I'm so U.S. centric. :-)
