  1. I'm trying to rip Mad Max Fury Road to fit on BD25. It'll fit with reencoding the video if I use ac3 audio problem The HD stream is TRUEHD/AC3 usually when I get this format I just use the core because it'll be at 640 and be done with it or there will be another english 5.1 track solely in ac3 by itself on a different stream. Well for some reason the core on the Mad Max (non 3D version, USA) the core is 384 and the extra stream is 448 and is descriptive audio. I want the main audio to be 640 ac3 so it'll fit on the BD25 and not be as low as 384 quality (the core).

    Problem is no program will let me just convert the TRUEHD to ac3 640 it wont work. I either get the core at 384 or the huge 5GB TrueHD (which wont fit). Am i gonna have to convert TRUEHD/AC3 to DTS-MA somehow then back to 640 ac3 since no program so far will let me convert straight from TRUEHD to 640 w/o error or giving me 384 core instead?

  2. eac3to should encode it, try something like this:
    eac3to.exe "C:\demux\movie.thd+AC3" "C:\encode\movie.ac3" -640 -down6 -down24

    There is a round about way to do it

    In BD_RB create an Alternate output >> Intact video --- Intact audio to MKV
    It will separate the TRUEHD from the core
    Use MKVMerge to remux just the tracks you want >>> Video, TRUEHD audio, subtitles
    Import to BD_RB and encode to BD25

    Are you talking about BD structure to BD structure?

    You should be able to use EAC3to to extract the TrueHD without the core, then re-encode the core to 640kbps.

    http://forum.doom9.org/showthread.php?t=172060

    Then use TSMuxer to mux it all back into m2ts files to replace the original files. Re-encode from there.

    It could be simpler or harder than that.

    It should be possible, but it depends on what you're actually doing and what programs you're using.

    The TrueHD i can get byitself but its 5GB and makes it too big for BD25. When I try to reencode the TRueHD to 640 it errors out or gives me the384 core.

    The core is 384 naturally if I reencode it to 640 it'll still be 384 quality just bigger. Upsize your fries with that? More fries, but still the same crappy fries.

    I'm confused at to what the hell you're trying to do.

    EAC3To can take a TrueHD stream without and core and create a new one for it, hence "re-encode the core".

    I don't know if you need that because I don't know what you're doing or what you intend, but whatever the hell you're doing it can't be that hard. The hard part is giving you advice without knowing the actual goal.

    If it helps, Fury Road is an Atmos stream. If the programs you're using aren't up to date they'll crash while attempting to read it.

    But updated programs should have been the first thing you tried.

    Simple Make TrueHD/AC3 (384kbps core) a 640kbps AC3 and I get an error: [09:50:44] Bitstream parsing for track 3 failed.
    [09:50:45] Demuxing this track may still produce correct results - or not.

    Thanks yes this helps a little.

    The goal: Get BD50 Mad max Fury Road onto BD25 w/o reencoding video. If I keep TRUEHD it's too big for BD25 (w/o reencoding video) if I use ac3 it fits. Only way to do this is get rid of all audio/video streams except main video & audio in ac3 format. 384 core quality is too low for me, hence why I want 640 ac3.

    ANYWAY THANKS ALL!

    Anyway thanks guys, I already made a backup copy and just used 384 stream. This audio is different than the norm due to the 384 core and the fact it errors trying to do TrueHD (w/o core) to ac3. Prolly because it Atmos like ndjamena mentioned. Normally i use core cause its 640 or the TrueHD will convert to 640 w/o errors.

    Are you trying to keep the menus?

    In what format do you need it?

    Is it ok to simply point MakeMKV at the thing, because I know for a fact that using MakeMKV to re-encode the TrueHD into an MKV will work.

    Then all you need to do is re-encode the video and shift the title into a blu ray format.

    MKVMerge should separate the TRUEHD from the core
    Remux and keep the TRUEHD track in the MKV
    Import to BD_RB
    Output to BD 25 --- make sure the appropriate audio options are selected
    This is how I did it -- and it worked

  11. Are you using eac3to to demux your stream before? Make sure you use latest eac3to. You do not mention what software you use.
    eac3to.exe "F:\BDMV" 1) 3: "C:\demux\movie.THD+AC3"
    1) would mean title 1 on BD and 3: track 3. I do not have that BD so your numbers might be different
    or follow this to run commands in a sequence to know what you have on that BD

    Mad Max Fury road with a 640kbps AC-3 stream. And yes, it would fit nicely onto a 25GB disc. The audio wasn't only larger than it needed to be because it was Atmos, being Atmos the TrueHD had 7.1 channels as well, which would be why the AC-3 core was given such a low bitrate.

    Converted to a BD structure and written into an iso it comes out as 24,185,143,296 bytes in size.

    Code:
        <outputSettings name="AC3-640" outputFormat="AC3">
            <description lang="eng">Save as AC3 (640kbps)</description>
          <extraArgs>-b 640k</extraArgs>
        </outputSettings>
    
    
        <audioMixSettings name="Down51"
            outputChannelLayout="5.1">
            <description lang="eng">Downmix to 5.1</description>
        </audioMixSettings>
    
    
        <trackSettings input="TRUEHD-multi">
            <output outputSettingsName="copy"
                    defaultSelection="$app_DefaultSelectionString,-sel:all">

  13. I use BD-Rebuilder (50.11), i would think Jdobbs would add an updated eac3to program thats builtin if needed but perhaps he hasn't I'd have to check. Well i just checked and could of sworn BD-Rebuilder used eac3to but i couldnt find the executable in the tools folder or any other folder for that matter. (i have only slept 4 hours though so maybe im missing it)

    Ok im getting the latest 3.31 eac3to and as far as mkv i didnt think bluray standards would accept mkv on a BD25. I can make another better copy with my real copy.

    It doesn't.

    The MKV contains h.264, ac-3 and pgs.

    TSMuxer takes those tracks out of the MKV and puts it in an m2ts. They're the same codecs, they don't change because they've been in another container. An AC-3 track made by MakeMKV is the same as an AC-3 track made by the official Dolby encoder for a Blu Ray. All TSMuxer needs to do is take it out of the MKV and put it into an m2ts file and no program should be able to tell the difference.

    All you have to do is use eac3to command prompt to extract the AC3 embedded audio file.

    The core was 384kbps, he needed 640kbps and apparently he was finding it difficult.

    I think I've heard it said that the FFMPEG AC-3 encoder used by MakeMKV is better than the Aften AC-3 Encoder used by EAC3To.

    I may be mistaken there though.

  17. Good lord I just update eac3to from 2.27 to 3.31 and ran ClownBD no errors, no problems immediately converted to 640. Guess it was just a simple as an update. Apparently 2.27 cant handle the Atmos stream. Thanks guys
