Concerning the Blu-ray compatibility discussion with Level 4.0, is the following list a summary of key options/limitations? (media I would like to use is DVD9)
  • VBV-maxrate: 25000 (with L4.1 I used 30000)
  • VBV-bufsize: VBV-maxrate - audio-bitrate - some headroom for subtitles (???)
  • no b-pyramid
  • no multiple slices required
  • ref: 4 (formula gives 4 for 1920x1080 for L4.1, how about L4.0)?
  • bframes: 3
  • min-keyint: 1 (or 2?)
  • keyint 48 (2x fps)
  • nal-hrd + aud option

Could someone please confirm that these settings are maxed out within the limits of the Blu-ray specs and (probably only concerns VBV) should not be less compliant for BD9s? As many others already said, I also hope to achieve max. BD compliance with x264 and L4.0 with BD restrictions seems to be covered entirely by x264 by now.
