No AC3 5.1 on some blu rays?

awtlaw · Post by **awtlaw** » Wed Sep 15, 2010 6:37 pm

I use handbrake to encode blu ray movies. When I encode the blu rays I always use high profile for the preset and I change the container to MKV and check large file size. Using the high profile preset there should be AC3 5.1 surround sound in the videos, but i am finding that some of my finished files only have stereo sound. Is this because the particular blu ray doesn't have ac3 sound originally or am I doing something wrong? If it is because the blu ray doesn't have ac3 on it is there anyway I can change the settings to get 5.1 for those blu rays. Here is a list of the blu rays that i have this problem with getting the ac3 passthru:
Fast & Furious
Forest Gump
Lord Of The Rings - All 3
Marley & Me
Mr & Mrs Smith
Notorious
The Blind Side
The Book OF Eli
The Bourne Identity - All 3
The Karate Kid
Walk The Line
X-Men The Last Stand

Well, apparently these blurays were previously encoded with something else since your input file is an mp4.
Your input doesn't have ac3 audio. So there will be no ac3 in the output. ac3 output is passthru only, so it requires that the input have an ac3 track. Hell, your input doesn't even have 5.1 audio at all. You can't make something from nothing.

Code: Select all

  + audio tracks:
    + 1, Unknown (DTS) (5.1 ch) (iso639-2: und), 48000Hz, 1536000bps
    + 2, Unknown (DTS) (5.1 ch) (iso639-2: und), 48000Hz, 768000bps
    + 3, Unknown (DTS) (5.1 ch) (iso639-2: und), 48000Hz, 768000bps
    + 4, Unknown (AC3) (Dolby Surround) (iso639-2: und), 48000Hz, 192000bps

Your source has an ac3 track, but it's not the track you selected for output and it's not 5.1 anyway. So for movies like this, you will not get the ac3 track.

Handbrake cannot convert DTS to AC3. AFAIK, all of the Bluray discs you've mentioned feature either DTS-HD or DTS-MA audio tracks. If you need AC3 (like for AppleTV playback), you'll need to convert them with another tool (eac3to is the one I use) first. If the Bluray features Dolby TrueHD soundtracks, Handbrake should have no problem extracting the AC3 core track.

I need to get the ac3 track. is there some sort of tutorial on how to use eac3to? I downloaded it but i can't figure out what i need to do with it.

So, eac3to extracts the ac3 audio and does it combine the audio and video back together or can handbrake do that?

This was something I was planning on adding to the thread I created awhile ago discussing using HDDVD and Bluray sources with Handbrake (http://forum.handbrake.fr/viewtopic.php?f=14&t=9258), but I never got around to finishing it. Now that it looks like I'm going to revisit my entire HDDVD/Bluray catalog with the release of the new AppleTV, it is on my list of things to do. Until that happens, I can only point you to the wiki that taught me the basics... http://en.wikibooks.org/wiki/Eac3to/How_to_Use.

In my workflow, I use eac3to to extract the audio, video, and chapter tracks (subtitles as well if I know the disc uses forced subtitles) and then use tsmuxer to combine the output audio and video into a m2ts container that can be fed into Handbrake. This is discussed in the first post of the thread I linked to above.

I have the Blu ray disc ripped to my hard drive. I have eac3to and the gui both in the same folder and i open eac3togui. I can't import anything into ac3togui because it doesn't recognize any of the files in the blu ray folder. Do I have to convert the blu ray to a mkv file first or what am I doing wrong.

I am just following what your tutorial says and it says to rip the disc and then use eac3to to extract the audio, video, chapters, and subtitle files. I can't get eac3to to recognize the blu ray files though.

They describe the best way to go about scanning a HDDVD/Bluray disc here:
