From 29.970 to 23.976 fps, do not change the audio. Inverse Telecine (IVTC) does not change the playtime.

But I've encoded from 25 to 23.976 and it had changed duration... That was done with MeGUI
But MeGUI doesn't support 29.970 audio !
That's why I'm looking for eac3to

Of course. Converting a video from PAL (25.0 fps) to NTSC-Film (23.976 fps) does change the playing time if you use the slowdown method.

But converting a video from NTSC (29.97 fps) to NTSC-Film (23.976 fps) does not change the playing time if the video was telecined and can be reverted to progressive using IVTC. Therefore, MeGUI does not need to offer any audio conversion. The audio does not need any conversion, because the playing time won't change. But only if you can invert a telecine.

What if I convert 29.970 to 25.000 fps...
And then convert it to 23.976 ?

What if you first read basic material about video before confusing this thread?

Hi

Are there any development handling dolbyTrueHD audio?
It can extract the THD stream, but not the AC3 core, neither THD+AC3.
Any way to extract AC3 core?
Suggestions are welcomed.

bye

I have a Blu-ray that causes eac3to to show only one playlist (the wrong playlist), even though playing index.bdmv plays a different one (the correct one). I've zipped the contents of the PLAYLIST folder and included a few files for debugging.. if madshi still secretly develops this.

With TSmuxer, check "downconvert True HD ..." in track options and choose demux as output format. Don't worry, that's an extraction, not a conversion (encoding).

Ooops, too late. Why didn't you create a bug tracker entry for this, then I might have looked at it. Now 3.28 is already done.

Anyway, are you sure that the real playlist and the one selected by eac3to are really different? Often there are multiple duplicates, and eac3to simply selects one "by random".

eac3to v3.28 released

http://madshi.net/eac3to.zip

Code:
* fixed: #001: different number of frames for left and right eye
* fixed: #061: valid silence edit was sometimes rejected
* fixed: #067: error messages were not available to GUIs
* fixed: #086: left/right eye information was inverted in some 3D Blu-Rays
* fixed: #131: TrueHD Atmos streams could not be demuxed or decoded
* fixed: #243: ArcSoft DTS decoder crash made eac3to crash, too
* downStereo: added 0.7071 factor for surround/back channels (ITU-R BS.775-3)
* downStereo/Dpl: using 0.5 instead of 0.7071 factor for LFE (ITU-R BS.775-3)
Please note that some of these changes have been implemented without a lot of testing. So it would be great if you guys could double check things, especially the changes, to make sure they really work as intended. Also please make sure TrueHD decoding still works losslessly, as usual (even for non-Atmos tracks). I've hacked Atmos "support" into the old ffmpeg version I've been using for years, so I wouldn't have to update to the latest ffmpeg version. Don't have much time atm, so I tried to do the most important stuff with the least amount of work.

TrueHD has no core in the sense that DTS-HD does. You can't extract what isn't there. If it's not THD+AC3 there's nothing to extract. It would have to be encoded.

Is there a reason to stay with a several years old ffmpeg version ? There's probably been a lot of fixes and improvements since.

There is something to extract, for example the latest version of mkvmerge can get the embedded AC3 track for you.

Have you bothered to read the announcement post? Read the last sentence again.

The bug #86 with the inversion of the left and right eye views when displaying the content of a 3D playlist with the MVC_Base_view_R_flag true is partially fixed.

When eac3to is launched with the BD path as the argument, or with the playlist, it works fine:
Code:
C:\>eac3to.exe Y:\BDMV\PLAYLIST\00852.mpls
1) 00852.mpls, 00001.m2ts, 1:34:02
   - Chapters, 20 chapters
   - h264/AVC (right eye), 1080p24 /1.001 (16:9)
   - h264/MVC  (left eye), 1080p24 /1.001 (16:9)
   - DTS Master Audio, English, multi-channel, 48kHz
   - DTS, French, multi-channel, 48kHz
   - AC3, Spanish, multi-channel, 48kHz
   - AC3, Portuguese, multi-channel, 48kHz
   - AC3, Danish, multi-channel, 48kHz
   - AC3, Finnish, multi-channel, 48kHz
   - AC3, Norwegian, multi-channel, 48kHz
   - DTS, Russian, multi-channel, 48kHz
   - AC3, Swedish, multi-channel, 48kHz
   - AC3, Chinese, multi-channel, 48kHz
   - DTS, Japanese, multi-channel, 48kHz
But when the 1) argument is added to display the full content of the playlist, the left and right views are still inverted:
Code:
C:\>eac3to.exe Y:\BDMV\PLAYLIST\00852.mpls 1)
M2TS, 2 video tracks, 11 audio tracks, 12 subtitle tracks, 1:34:02, 24p /1.001
1: Chapters, 20 chapters
2: h264/AVC  (left eye), 1080p24 /1.001 (16:9)
3: h264/MVC (right eye), 1080p24 /1.001 (16:9)
4: DTS Master Audio, English, 7.1 (strange setup) channels, 16 bits, 48kHz, -9ms
   (core: DTS-ES, 5.1 channels, 1509kbps, 48kHz)
5: DTS, French, 5.1 channels, 768kbps, 48kHz, -9ms
6: AC3, Spanish, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
7: AC3, Portuguese, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
8: AC3, Danish, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
9: AC3, Finnish, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
10: AC3, Norwegian, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
11: DTS, Russian, 5.1 channels, 768kbps, 48kHz, -9ms
12: AC3, Swedish, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
13: AC3, Chinese, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB, -9ms
14: DTS, Japanese, 5.1 channels, 768kbps, 48kHz, -9ms
15: Subtitle (PGS), English
16: Subtitle (PGS), French
17: Subtitle (PGS), Spanish
18: Subtitle (PGS), Portuguese
19: Subtitle (PGS), Danish
20: Subtitle (PGS), Finnish
21: Subtitle (PGS), Norwegian
22: Subtitle (PGS), Russian
23: Subtitle (PGS), Swedish
24: Subtitle (PGS), Chinese
25: Subtitle (PGS), Japanese
26: Subtitle (PGS), Japanese
(This is the Ice Age 3 3D Panasonic Bundle. I haven't tested with the 2 other 3DBDs I have with the inverted views, but I guess they give the same result.)

I'll need a sample. One which is complete enough so I can fully reproduce the incorrect listing.

I'll make some test and report.

No problem for me, that enhance a little the front channels info (more important) over the surround channels.

Quote:

I can't se this recomendation in ITU-R BS.775-3, I only read than LFE don't be used at all in downmix.

@all users
Please read ITU-R BS.775-3 to understand for what add LFE is not recommended for downmix.
Use -mixlfe at your risk.
