  squeezed conversion 16:9 to 4:3

  Posted by Lasse Laursen on September 27, 2009 at 3:32 pm

  I have a 10 second spot shot in Panasonid HD (960X720 50fps)

  The client needs the final spot in the following specs.

  Mpg2 program stream (audio and video together) field order B (.mpg)

  720:576 pixels, 25 fps. (Pal DVD) 24 bit, 4:3

  Gop: 1

  Gop : 12

  I-Frame distance: 12

  Reference distance: 3

  I have managed to find and adjust all of the above besides I-Frame distance, Reference distance and field order inside compressor. Are they possible to set from compressor?

  The final question, and this might be a bit n00b, but when coverting my 16:9 footage (960X720 50fps) to 4:3 (720X576 25fps) my export gets squeezed. I want to keep the aspect ration and just have the exported mpg2 file letterboxed.

  I hope i make just a tad of sense.

  Best regards

  720×576 can contain either a 4:3 or 16:9 frame aspect. Simply select 16:9 as the desired target in compressor, it’ll look squashed until you view it through a DVD player, VLC etc.
