  encoding with VBR

  Posted by Steve Ralston on February 12, 2012 at 2:04 pm

  Hi,

  I have made 2 x 73min films I would like to put onto one DVD. I cut them in Avid and exported 2 high res H.264 files as masters.

  I have then used Apple Compressor to make MPEG2 files. I used the setting ‘DVD Nest Quality 150min’

  The quality isn’t great. I have heard you can encode it VBR so it gives more data to complex parts of the film and less to others to maximise overall quality. I can not work out how to do this with Compressor. Does anyone know how and what settings I would have to use?

  Thank you in advance.

  Steve

  That’s because h.264 is a delivery codec and not a mastering one. Spit out an uncompressed OT lossy codec like ProRes and Try it again

  Thanks for the reply Eric.

  Sorry, I don’t really understand what you mean by ‘uncompressed OT lossy codec.’

  I can output at ProRes. Just the normal one or the HQ version do you think? What about the VBR?

  Thanks a lot,

  Steve

  Sorry….my iPhone trys to correct my, already bad, spelling. I meant “uncompressed OR lossy” . The normal Prores is fine for DVD

  With that much time on a disc you definitely need to go VBR. It will do a 2 pass to determine what bitrate it best for what scenes

  FYI – Apple presets are horrible. They are way too high on the max and too big of a spread. 2 pass VBR takes longer but gives you a more acturate file size. Set the average to 3.8 and the to 6Mbps. Make sure you encode the audio to ac3 at .192Mbps.
