    Exporting H.264 Blu-ray material in CS3

    wonderspark Community Member

      System:

      2009 Mac Pro 3.33GHz Quad core

      Snow Leopard 10.6.5

      16GB RAM

      Radeon HD 5870

       

      Adobe Premiere Pro CS3, 3.2.0

       

      Video material:

      DVCProHD, 1080p60i/24p, 23.976fps shot on P2, MXF file format.

       

      Exporting to:

      H.264 Blu-ray via Adobe Media Encoder

       

      I can render Blu-ray material, and even burn it in an internal LG 10x Blu-ray burner that I installed.  The result was wonderful when played back on a Blu-ray player and HDTV.

       

      What I cannot figure out is why I have to render projects in small little segments, rather than one large one, and then line them all up on a timeline in Encore.  I then have to rearrange my chapter points, since Encore places a chapter marker at each clip.  It's not the biggest deal in the world, but it's just annoying.

       

      I've tried different settings, and the one that gives me the most success is starting with the preset for H.264 (Blu-ray), HDTV 1080p 23.976 High Quality, and switching the Profile from High to Main, and leaving the rest alone.  I'm not sure if I tried HDTV 1080i 29.97... maybe I should.  Whether it crashes or not seems to depend on how many effects are in the clip, or how long the segment is, but I can usually get away with up to about 10000 frames of video without a crash.  The crash almost always occurs during the second pass of VBR encoding.  It closes Premiere and offers the crash report window, which I am not good at decyphering.  Anyway, I always submit the crash report with what I was trying to do.  Adobe has many of them from me now.

       

      Can anyone shed some light as to why it only allows 6000-10000 frames go through this encoding process?  My system will show that it only used about 6 out of 16 GB of RAM after a fresh reboot.  It helps if I reboot between each encode session, as well.  If I try to encode two short segments without rebooting between, I usually get a crash.  Also, I can encode DVDs just fine with the same project.  I encoded the 105 minute movie with all the same effects, clips, etc. and the DVD was flawless on the first try.  It's just the H.264 Blu-ray setting that jacks it up.

       

      I'm glad I can get the thing done piecemeal, but I was hoping someone could at least explain why it's so difficult. (:
