Any ideas?

[Thunderbolt8]

if the movie is in sync afterwards, dont care whats written there.

if not, try to add the .m2ts files (1+2+3...) manually instead of using the playlist.

[hoju3508]

Yes, it's in sync but TMT3 thinks it's a 13 hr movie for some reason. It's kind of odd.

I might give this a try. Thanks.

Hello, my source audio file is 25fps ac3 with 2 front channels and 2 rear channels. As for now Im using this code:

eac3to "input.ac3" "output.aac" -quality=0.30 -changeTo24.000 -down2 -phaseShift -mixlfe -resampleTo44100 -25.000

I want to enlength the audio to fit into the 24fps film, and downmixing all channels to Stereo 2. Does -phaseShift fix the pitch problem when changing audio lenght? and second, with this code I still have the 4 channels, how can I downmix them to 2?

Nope. BTW, don't use -phaseShift never with ac3 source.
And -mixlfe do nothing because don't exist LFE channel in the source

and second, with this code I still have the 4 channels, how can I downmix them to 2?

The -down2 parameter only work with 5.1 source.

You can use an .avs file like this:

a = NicAc3Source("D:\path\input.ac3")

# 4 Channels Quadro L,R,SL,SR, downmix to simple stereo
#  flr = GetChannel(a, 1, 2)
#  blr = GetChannel(a, 3, 4)
#  MixAudio(flr, blr, 0.5, 0.5)

# 4 Channels Quadro L,R,SL,SR, downmix to DPL II
  flr = GetChannel(a, 1, 2)
  bl  = GetChannel(a, 3)
  br  = GetChannel(a, 4)
  sl  = MixAudio(bl, br, 0.3714, 0.2144)
  sr  = MixAudio(bl, br, -0.2144, -0.3714)
  blr = MergeChannels(sl, sr)
  MixAudio(flr, blr, 0.4142, 1.0)

# [DSP: TimeStretch - 25 -> 24] pitch preserved
  TimeStretch(tempo=96)

# [DSP: Resample SSRC - 44100 Hz]
  SSRC(44100)

# [DSP: Normalize to 100%]
  Normalize()

and encode with NeroAacEnc to .m4a with MeGUI, BeHappy or Wavi.

[Dogway]

Just WOW! it worked perfect. I didnt know I could load an avs into the audio input of MeGUI. Aside solving my issue, I just learned a little more, I hope this enlighting post awakes an interest on me on the audio part of the digital encoding.gracias

BTW what bitrate do you recommend me for medium quality towards good in m4a/AAC? something like 128,160 of mp3.

Also, in your script you are downmixing, normalizing,etc but in Megui the audio encoder also does its stuff in the Config options. Do I need to uncheck, keep originals everything from the options?

To transcode from lossy sources (AC3,DTS,...) I always recommend at least -quality=0.35 (AAC-LC), with 0.30 you obtain AAC-HE, and is not always compatible with some players.

Also, in your script you are downmixing, normalizing,etc but in Megui the audio encoder also does its stuff in the Config options. Do I need to uncheck, keep originals everything from the options?

A little offtopic but ...
Yeep, you need uncheck all, or don't put Resample/Normalize in avs and use the Config options.
(These two functions are equivalent to eac3to, resample with SSRC lib).

The predefined downmix with MeGUI/BeHappy work only with 5.1 sources, like with eac3to. Then you need include the special downmix avs method for sources with 3,4 or 5 channels.

The change audio duration (for different fps video) in MeGUI only work for 23.976 <-> 25 using SSRC method without preserving pitch (like eac3to, but eac3to have more options).
To preserve pitch you need use the AviSynth function TimeStretch(tempo) included in BeHappy.

I have just found something weird on "Fringe Season 2" BD. On disc three, the playlist for episode 14 "Jacksonville" is not listed by eac3to. It is relatively obvious that this must be 00072.mpls. Running eac3to on this file shows the right length (about 40 min), but instead of showing 00027.m2ts it shows 00027.m2ts+00027.m2ts and consequently demuxes files of double length.
With this length, eac3to should actually list this playlist aswell, but maybe there is an error in the playlist?
In any event, I just thought I would report this, perhaps somebody can make sense of it. Of course the problem can be solved easily by avoiding playlists for this episode and using the .m2ts file directly.

BDInfo shows the same. Also, 00075.mpls shows the same double file for 00023.m2ts. I think it's an error in the mpls files.

@deathlord, @cavediver

Hi!

Does the "Backup>>Playlist" sub-folder contain .MPLS files IDENTICAL to those of the primary "Playlist" sub-folder?

If I don't repeat the muxing then sometimes the audio can be really badly out of sync. It is not predictable how much. If I repeat the muxing as it says, it successfully makes the new MKV file without this error message. But then the audio goes out of sync by a small but very noticeable amount.

So repeating the muxing does do something but maybe eac3to needs extra help by having the file cleaned up by another program that can take care of the gaps etc before passing it on to eac3to? Any other ideas how I can stop the audio going out of sync?

Anyone having success (or failure..) with seamless branching titles?

Somewhere along the way they stop working for me - major audio sync issues, changing from scene to scene.

It's not clear if the automatic second pass is supposed to correct this, or if we need to make a manual third pass (and possibly manually compensate for an audio delay).


Umm..a little guidance? Please.

I don't think that's it.

Every seamless-branching title has this issue.


They all play fine in TMT, and if I process with MakeMKV, they work fine.

[madshi]

Just a quick answer: "The source file seems to be damaged" is *NOT* supposed to appear for seamless branching titles. I've never in my whole life seen it on my PC with any seamless branching title. Try ripping to harddisk with AnyDVD HD first and then run eac3to on the harddisk folder.

[Jeff Flowerday]

Bad Source: I had the same problem recently with my Cars Blu-Ray. I waited for a new AnyDVD HD, just installed the release from a few days ago, and the problem went away.

For my 00075.mpls it does not show a double file, at least not on disc 3.

Problem with ac3 conversion

Hi All:

I have a 25 fps PAL ac3 file I'm trying to slowdown to 23.976 fps so I can burn an AVCHD disc and play in my Bluray player. I do this regularly and have never had a problem. This file, although it plays fine in Media Player Classic, eac3to conversion hasn't worked.

When I looked at it more closely, it's characteristics differ depending on what I use to examine it:

MediaInfo for the mkv file (tsMuxeR does NOT recognize the audio track)
ID : 2
Format : AC-3
Format/Info : Audio Coding 3
Codec ID : A_AC3
Duration : 1h 27mn
Bit rate mode : Constant
Bit rate : 384 Kbps
Channel(s) : 6 channels
Channel positions : Front: L C R, Surround: L R, LFE
Sampling rate : 48.0 KHz
Stream size : 242 MiB (11%)

MediaInfo for the extracted audio track (using mkvextract)
Format : AC-3
Format/Info : Audio Coding 3
Duration : 1h 27mn
Bit rate mode : Constant
Bit rate : 192 Kbps
Channel(s) : 2 channels
Channel positions : L R
Sampling rate : 48.0 KHz
Stream size : 121 MiB (100%)

And eac3to sees the same extracted audio track as:
AC3, 5.1 channels, 0:44:00, 384 kbps, 48kHz, dialnorm: -22dB

Any ideas on what's happening here (or how to fix it)??

Maybe you have an AC3 with 2 kind of frames (a TV capture?, movie and commercials).

Try run:

SplitAc3 audio.ac3

and put the log file created.
