@Madshi
First i did that on Original Blu Ray Disc, i don't think in that last frame would be incomplete. And second time for you, i did that on sample by cutting starting piece. Secondly that mean, eac3to mux's exact stream to MKV, even if last frame is incomplete. And it only remove last incomplete frame in demuxing. Hope, i'm getting right. And i never mean to offend you, i just want help you by testing stuff. Last edited by sehgal.v7; 23rd August 2008 at 08:09. |

Thanks. This problem will be fixed in the next eac3to build.

(A)
1. Extracted 1080p24.vc1 from VC1.ts by Eac3to - (If any frame was missing, it must have been removed) 2. Made M2TS file with Scenarist. Then Extracted 1080p24.vc1 from VC1.m2ts. ------- Compared both files by Hex // both are same. (B) 3. VC1.m2ts to VC1.mkv with Eac3to. 4. Extracted 1080p24.vc1 from VC1 by MKVExtract. ------- Compared 1080p24.vc1 (A) & 1080p24.vc1 (B) by Hex. Lotsa difference!! Here's the Report!! hxxp://rapidshare.com/files/139456657/Report.rar |

The only difference between the two files is that one them has one frame missing. One of the files contains 433 frames while the other contains 432 frames. But those 432 frames are 100% bit perfectly identical. |

Thanks Madshi, got every single clearance on VC1. Jus one last ques- Are you planning to add feature to combine AC3 & TrueHD files together? :-) Me still waiting to burn Blue Planet again ;-) Last edited by sehgal.v7; 23rd August 2008 at 12:30. |

madshi, I now found a workaround (tsMuxer combined with TsRemux) to get TrueHD tracks (with ac3-core) to work on 'homemade' Blu-rays.
I tested it myself and the TrueHD tracks plays perfectly and the core also gets recognized. So I would like to ask you nicely when you have time for it to check out if it is possible to remove dialog normalisation from these type of tracks. How can it be done? I guess you have to find a way to remove the dialog normalisation from both the headers in the file? |

"I may eventually add a feature to create an interweaved TrueHD+AC3 track for Scenarist muxing."
Oki, will be waiting for that. Secondly, i was jus experimenting with files.. If TrueHD stream contains only 16bit Information, when converting it to WAV, why it outputs 24bit?? Quote:

i also can confirm that VC1 is bit-perfect. so, what we have till now:
- MPEG-2: bit-perfect. - VC-1: bit-perfect, but usually the last frame is missing (at least on all test i run the last frame is always missing, anyway it's not a problem) - H.264: AUDs and "filler data" are removed, but as madshi explained they are useless data, all other data are bit-perfect, but always have "the double sequence headers at the beginning of the stream". |

WAV channel order is L, R, C, LFE, LS, RS. Quote:
Correct. In this case you must NOT use "--raw", btw. And I want to add that I don't consider the AUDs to be useless for a continuous stream of bytes. I just consider AUDs to be useless inside of an MKV or MP4 container. IMO an MKV/MP4 demuxer which targets to create a raw h264 file should readd AUDs. Sadly current demuxers don't do that. Maybe some day I'll have to write my own MKV demuxer. But it's not a big deal since AUDs are optional, anyway, and decoders don't need them in any case. |

@Madshi
Thanx for fixing bug in next release. Secondly, Scenarist is accepting L,C,R,LS,RS,lfe config for while. Screenshot http://rapidshare.com/files/139543028/Untitled.jpg |

I'm not sure but I guess that's the channel order which Scenarist will write into the final m2ts file and *not* the channel order it expects in the wav file. The wav file channel order is standardized and eac3to uses the channel order which everybody uses in wav files. Scenarist expecting a non-standard channel order in the wav file would be quite strange.

So, I'm trying to convert CJ7 (the newish Steven Chow movie) to MKV and running into quite a bit of difficulty.
It's a multi-part (But I've dealt with that before by muxing together with tsmuxer.) However, there's some problem with the streams, when running tsmuxer or eac3to I get many alerts of the type The program channel mapping changes in the middle of the stream. So, I'm demuxing each seperate m2ts file using eac3to and I'm going to try to then combing together the h264 files into 1 mkv and the ac3 files into 1 ac3. However, I'd love any tips regarding correct command line options for this phase and any gotchas to look out for to make sure I'm getting rid of audio overlap and will have a final product where audio and video are in sync. EDIT I guess specifically my question is in madshi's quote he says audio overlap can then be fixed, how?? END EDIT Thanks Quote:

Madshi:
Re: "The Bank Job" AVC/7.1 DTSHD The AVC video track duration is 1:54:34.075 -core eac3to extraction yields a 1:52:01.749 DTS file If I instead convert to AC3 with eac3to, we get a 1:54:34.075 file... and muxing this to the video gives perfect sync. Obviously, a mux of the -core DTS and AVC video gives a very big video/audio sync problem. But, I'd like to get the -core DTS and AVC together... thoughts? |
