DTS-HD MA to DTS core

[hardy]

I know there have been many discussions about this topic. Someone please refresh my memory. I have been trying to find an easy to use GUI using eac3to. All I want to do is extract the DTS core from the DTS-HD MA. Then I can mux everything together with mkvtoolnix.

I'm not so sure this is the easiest way, but you can use ClownBD for this if you are starting with a Blu-ray source.

De-select everything except the audio, then put a mark in the Audio option called Core. You can set the output as a .ts file, then rename it to .dts after it is done, or you can look in the demux location and there should be .dts file there already.

My videos have already been encoded. CloneBD does not recognize mkv containers, unfortunately. I haven't tired using Clown_BD

1080p video with DTS-HD MA

[imhh1]

you can use the downconvert DTS-HD to DTS option with Tsmuxer .

[hardy]

For the output file, should I use TS muxing or Demux?

[imhh1]

doesn't matter, every output will have the dts core.

[hardy]

TS muxing gives the option to adjust the millisecond count. Demux takes that option away

HD-DVD/Blu-Ray Stream Extractor. There's a newer version here that works properly with the latest eac3to. It doesn't seem to have been uploaded to any other sites for some reason. Alternatively, if you're an MeGUI user, you can find the HD Stream Extractor under the Tools menu.
From memory, if you select "DTS" as the extraction method (as opposed to DTSHD), you get the DTS core.

yes if you also want to add a delay, you can't just demux.

I will try using the Stream Extractor and eac3to

[Justin9]

It's just (using cmd prompt) "original name".dts "output".dts -core
It's very basic so you don't need a gui

[hardy]

Any step by step instructions for using command prompt and eac3to?

[Justin9]

I use MKVCleaver to remove the DTS stream from the container. I then (Win 10) just type CMD in the search that brings up the Command dialog box. In that you type the command lines. Then you need to be in the same directory that you have the eac3to directory. So, for that if you have it, say, on the root of you drive, you simply, type "cd" then space and the directory such as C:\users\name\eac3to , then you should be in the directory, then you type in the command I said earlier. Remember you don't type the quote marks and you have to put in the names and it should do the extraction super quick.

[hardy]

I'm familiar with mkvtoolnix, will this also work to remove the DTS stream?

Edit: correct line once I have the stream?

eac3to input.dtshd output.dts -core

[Justin9]

Not sure about mkvtoolnix for grabbing the stream - just haven't done that.

Extract dts core from dts-hd

[hardy]

@ anana, that must be in a new release
I'm running v6.9.1 and I don't see the "Reduce to audio core" option

It's v8.3.0

It's definitely an easier option. Better than using eac3to?

Edit: I used both methods. Here are the results.

mkvtoolnix 0.98 GB (1,062,318,929 bytes)

eac3to command line 0.98 GB (1,061,613,692 bytes)

[hardy]

Decided to only use eac3to command line
I have a question about the log. Does the (strange setup) actually mean something?

eac3to v3.29
command line: eac3to  input.dts output.dts -core
------------------------------------------------------------------------------
DTS Master Audio, 7.1 (strange setup) channels, 24 bits, 48kHz
(core: DTS-ES, 5.1 channels, 1509kbps, 48kHz)
Extracting DTS core...
Creating file "output.dts"...
eac3to processing took 35 seconds.
Done.

Sorry for the double post

[Justin9]

How strange! Honestly haven't seen this. How is the output file? Have you remiuxed the MKV and tested?

[El Heggunte]

Does the (strange setup) actually mean something?

Only if you intend to reencode the 7.1 audio to a different lossless format
(OR to a lossy format which supports more than six channels).
The "strange setups" are not compatible with the WAVE_FORMAT_EXTENSIBLE definitions.

[hardy]

The output file is fine. After muxing everything together. I was just wondering if there was a way to avoid (strange setup)
But everything seems to be working.

[hardy]

Solved. Mod can close
Thank you for helping!
