    5DM2 to BluRay - how to get progressive and avoid transcoding?

    Dmitry2010

      Hi,

       

      I'm trying to build Blu-Ray out of Canon 5D Mark II footage.

      Footage from the camera has 1920x1080 29.97p.

       

      Adobe Premiere in the case of "Export to Media" for both export settings of "H.264 Blu-Ray" and "MPEG2 Blu-Ray" apparently forces a choice of

       

      1) Check "Match sequence setting"

      Format - shown as "MPEG Preview"

      Output - 1920x1080, 29.97 fps, Progressive, Quality 50

      Video Codec - MPEG I-Frame

       

      Nothing can be changed - no quality setting, no data rate, no CBR/VBR-1/VBR-2 choice, only "Use Maximum Render Quality" checkbox is available below.

       

      2) Not to check  "Match sequence setting" but to use

       

      Format: H.264 Blu-Ray

      Format: MPEG2 Blu-Ray

       

      here I can set misc. quality settings, but aparently I cannot get progressive 1920x1080p 29.97 output at all!

       

      The choice on "Field Order" is either Upper, Lower or Automatic.

       

      Automatic apparently creates Upper.

       

      So interlace is... unavoidable???

       

      OK, I've exported a project - in 1920x1080, 29.97 Upper. Got .m4v and .wav file (audio was PCM).

       

      When creating Blu-Ray image in Adobe Encore I see that .wav has setting "Don't transcode" while I cannot get the same setting on .m4v file.

      Most decent choice is a trancode option "1920x1080i 29.97 Maximum Quality H.264".

      Even on my i7 it transcodes may be with 0.5x speed. (and why I need transcoding at all? both input and output is 1920x1080i 29.97)

       

      The best 1920x1080p option is "1920x1080p 23.976 Maximum Quality H.264". Why no 29.97 for progressive?

       

      In this 2-stage process of 5D Mark II => Blu-Ray apparently I got 3 issues:

       

      1) Adobe Premiere forces me to output an intermediate result in 1920x1080i, while I naturally want 1920x1080p.

      2) Adobe Encore wants to transcode "regardless" of both input and output apparently being 1920x1080i.

      3) I cannot attain 1920x1080p 29.97 in any way I know.

       

      What happened with 1920x1080p 29.97 Blu-Ray - why I cannot get it?

       

      Regards,

      Dmitry
