  downsizing mpeg bitrate

  Posted by Rob Wood on July 1, 2008 at 1:35 am

  Hey guys; I have mpeg2 files of feature films for a dual layer dvd product, the files were used for digital cinema screenings so they are encoded at around 29 mb/ps (weighing in at around 20 -25 gb). I need to re-encode these files to fit on dual layer DVDs; I’m working on DVD studio pro which won’t allow bitrate changes to files that are already encoded. I’ve tried using compressor but the resulting files will encode to a certain point and then just crash or just shows a black screen with no audio. I’ve gotten around this in the past by converting the files into other formats and then re-encoding but I’m sure there’s a more efficient method; I’ve searched around but found no information…anybody ?
  Cheers

  Never a good idea to reencode mpeg2 files but if that is all that you have then yes you have to convert them to an “editing” codec, I recommend going to 10-bit (or 8) compressed then take that into Compressor and encode back to mpeg2.
