Been having some problems with stuttering all of a sudden. Unfortunately I have just too many new variables to track this down and hoping someone can point me in the right direction. I used to use windows for all my blu ray stuff, but I've been using all mac here lately so a lot of my pipeline is still being figured out. imac 27" i5 quad core, using MakeMKV to encode to a .mkv file, stripping out all the other junk from the file (subtitles, other audio tracks, other chapters, etc). From there running through handbrake snapshot svn3154 x86_64 (2010030701) using default appleTV preset changed to 23.97, CRF of 22, detelecine and decomb on, changing height to 1280x720, anamorphic turned to off, using Dynaflash's advanced string: cabac=0:vbv-bufsize=9500:vbv=maxrate=9500:ref=3:mixed-refs=1:bframes=3:me=hex:subq=7:b-adapt=2:weightb=0:trellis=0:weightp=0. When needing to convert from DTS - I've been using Moyea MKVConvertor. Then from there I metaX the file, then add in the .ac3 file/subtitle/create chapter preview jpegs with Subler.
Within the last few weeks I've bought a new iMac, changed to doing this all with OS X and just not sure what is going on. I'm re-encoding a movie from 22 to 22.5 to see if that helps. I"m going to try it next with just the AAC file incase the .ac3 file being generated by moyea is doing something weird? never heard of audio causing stutter though. Any help would be appreciated!!
Here is an encode I did of Two Towers that is stuttering really bad:
