LPCM Soundtracks = Big Headaches

I recently discovered the joys of LPCM soundtracks on VC-1 encoded Blu-Rays. The issue is that VC-1 is a bitch to transcode, so I have to convert the movie to H264. I can do that without quality loss, but the settings required to do that mean a 15 hour transcode on my quad-core i7 laptop. The problem is that the transcoder cannot do pass-thru on LPCM. The only way around that was to use a multiplexer to add the LPCM soundtrack from the first rip to the transcoded copy. It worked flawlessly.

I'm glad I only have a dozen or so movies with this issue, because the processing takes so long that I can only do about one per day.

Here is the process:
  1. Rip movie with MakeMKV
  2. Transcode movie with Handbrake at the same bit-rate as the original rip
  3. Use the multiplexer function of MKVToolNix to add the LPCM soundtrack from the raw rip to the transcoded copy of the movie.
 
Wouldn’t it be easier to just pop the BD in player and watch it with a cocktail and some snacks than to go through this drawn out process?

It only adds up to about 15 minutes of actual work and I only have to do it once. That said, I really do understand why some people shell out for Kaleidescape. Building a large library is a very time-consuming endeavor.
