Best way of dealing with 6.1 Audio Tracks?

<< < (2/3) > >>

The concept works using MC to "Convert Video to Audio" + DSP to convert the 6.1 track to 7.1 LPCM and I then used tsmuxer to mux it back in.  These 9 are however all in BD Structures on my HDD and 6 of them (Star Wars) use seamless branching across multiple M2TS so I'd then have to break up the audio.  + in theory I should then also use BD Edit to change the details of the Audio Track.  I'm thinking MKV looks alot easier at this point. 

I'm also not sure if I'll end up with the LFE issue on the Star Wars disks.

jmone:
So I've tested the following workflow of both a LOTR and a Stars Wars movie:
- BD --> MKV (MakeMKV)
- Import MKV Into MC and convert the DTS 6.1 to a 7.1 FLAC file
- Create a new MKV mux using MKVToolNix GUI removing the DTS 6.1 and adding the 7.1 FLAC track (and fiddle around working out the Forced subs)
- Import the final MKV info MC (deleting the temp MKV and FLAC file)

All seems to be fine but still a PITA as I prefer to just rip and play the original. 

The other option would be better 6.1 handling as I don't think most users would want to try the above.  Maybe something like:
- selectable Channel Mask held in the data base or
- an additional DSP option like "Always mix 6.1 to ..../5.1/7.1...."
- ??

Personally I would generally recommend to just tell MC to always mix to your physical speaker count, and you never have any problems.
There are plenty other "uncommon" layouts that cause trouble with HDMI AV-Receivers, basically anything thats not 2.0, 5.1 or 7.1, to be honest. This would magically squish all of these!

jmone:
I agree that it solves all the channel layout probs, and I've been using 5.1 Mixing due to the 6.1 issue... but I've been using "Source # of Channels" for the last few years as I found that on 2ch Video that dialogue with MC is less focused on the Center speaker than what the AVR does (eg it tended to be spread over the front 3 channels).... but let me check again as I could be wrong.

RoderickGI:
I mix everything to 5.1 and encode to AC3 to send to my AVR because that's all it will accept in a 5.1 digital format. Not ideal, but it works.

However, I did notice on some programs that the dialogue could be a bit weak, and so I have boosted the Center channel a bit to compensate. Again, not ideal but it works.

Everything is a little bit of a compromise, but that is okay.
