Re-rip audio in mkv file to lossy?

[MCNI]

Description of problem or question: I have a device that plays 4k MKVs without any difficulty except that it does not recognize lossless audio formats like DTS-MA or TrueHD. Is there any way to rip those files in Handbrake to leave the video untouched but convert the audio to a lossy multi channel audio format?





HandBrake version (e.g., 1.0.0):1.3.0




Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update): OS X 10.12.6

No, handbrake is primarily a video encoder, so it's always going to encode the video.

You can use tools like ffmpeg to encode JUST the audio tracks.

Try mkvtoolnix

I'd use MakeMKV here with the original disk, rip the video track with the lossy core audio.

I use eac3to. It's a command line tool and there are GUI tools that works with it, they just sucks.

I just have some batch files, named like "Batch - DTS to AC3.bat".
The code will look something like:

Code: Select all

eac3to.exe "D:\Video\Source.dts" "D:\Video\Destination.ac3"

or...

Code: Select all

eac3to.exe "D:\Video\Source.mkv" "D:\Video\Destination.ac3"

or..

Code: Select all

eac3to.exe "D:\Video\Source.mkv" "D:\Video\Destination.ac3" -640

to provide a new sample rate.
It's however not all cases where you can provide the .mkv file directly, but have to extract the audio first.

There are options you can/have to give in some cases, like down mix from 7.1 to 5.1

Code: Select all

eac3to.exe "D:\Video\Source.dts" "D:\Video\Destination.ac3" -down6

or... extract the tracks to .wave format, so that you can use another .wave editor to create your own file formats:

Code: Select all

eac3to.exe "D:\Video\Source.m2ts" "D:\Video\Destination.wavs"

The easiest, is to just put your batch files in the folder of eac3to, where eac3to.exe is.

It was easy to miss, but

Oh well...

Life is somewhat easier with Windows.

ffmpeg can do most of what eac3to does nowadays (except automatic bit depth reduction and the Blu-ray playlist features, and not sure it does audio normalization either).

eac3to relies on ffmpeg along with other software to do it's job. But it's very easy and powerful to use.
