    Pulsing compression on blu-ray m4v output


      I've seen this problem with compression on DVDs before, but not sure what I've done to solve it.  Now I've got an 80 minute output file for blu-ray, and in some areas, there is a subtle pulsing every half a second.


      I've already got what I thought were good compression settings:

      VBR 2 pass

      target bit rate: 30

      high bit rate: 35


      Searching online, I see mostly threads talking about DVD compression, not Blu-ray.  But the suggestions have been:

      (1) Change your GOP from 15 to 7.

      (2) Switch to Constant bit rate (CBR).


      First off, I'm new to Premiere CS6, and I don't see a way to change the GOP anywhere.


      Secondly, do I dare export a CBR file at 35mbps?  Is that going to make Blu-ray players work too hard and freeze up?
