  Cleaner 6.5-Compressor-MPGs422

  Posted by Rafael Amador on September 28, 2006 at 1:16 pm

  Hi,
  do anybody give some advising about Cleaner 6.5. I inted to usit mainly for MPG2 for DVDs. How is it comparing with Compressor2.
  I’ve got a question about MPGs with 422 sampling. Can them be printed in DVD? Can them be played in an standart DVD player? Are only for streming?
  Thanks in advance.
  Rafael

  From my experience, the Cleaner MPEG2 encoder is not that great. Compressor is better. Procoder is also better. Good hardware is best (we use the Optibase Moviemaker 200.)

  MPEG2 Main Level, Main Profile (DVD compliant) is 4:2:0. DVD would not handle the MPEG 2 4:2:2 profile because the data rates are so high (50Mbps) and it’s I-frame only. Sony IMX uses this format.

  The 4:2:2 profile can be used in an IP or IBP mode and at much lower bit rates, but you are correct that it will not be decoded on a standard DVD STB.
