Hi

Read the first post of this thread! It contains a link to the eac3to wikibook. There you can find many examples on how to use eac3to.

you mean i have to create a "ISO" and not a ".m2ts" file from
blu-ray??

anyway, the thread talk about mkv and not about extracting Audio & Video from a ".m2ts" or "Blu-ray" disc...or my english is
so bad???

To actually play it back you will have to combine Audio & Video into an mkv using mkvmerge. It will just extract them if that's what you want to do.

This is really OT for this thread. Post further questions in that thread and I'll try to answer them.

This is OT?

someone on this forum point me here and told me that eac3to is the program i need to extract from a ".m2ts" the audio & video!
i'm not talking about mkv....

Maybe i'm wrong, but i DONT think its OT.

someone else can confirm this, this program, eac3to, can do what i need? extractint the audio & video form a ".m2ts" file or ".ts" file?

i'm a still a noob with blu-ray,but i think i need someone more expert!
thx!

nautilus7 · 16th December 2008, 18:27

All these posts asking how to use eac3to...
You have been directed to where you can find examples. You can also search this thread. Saying that your English is bad is no excuse.

Anyway, is it so hard to look a few pages back and find an example with m2ts file?

What was OT was discussing the other (GUI) program and how it makes it easy to use eac3to and how it provides screenshots (which is what you asked for). I did try to answer your question but felt it would be better to not clutter up this thread with questions about that program.

I do use eac3to via that GUI constantly so I am at least considerably more expert than you. Since your English is so bad it's easy for you to misunderstand. You should realize this and at least be more courteous with someone who is trying to help you.

wasnt my intenction to be rude in any way, really.

...and my "bad english" is not a excuse...bha!

about 400 pages...

i'm "just" asking how to use eac3to...i dont think its a crime!
at last you can reply like you just do it! or maybe you need a "+1" on your post count?

like many other i'm asking this, because i didnt see any real guide, like many other programs
with screenshoots on how to use the programs,
at last i didnt find them, thats why i'm asking.

(do you see for example the guide of ripbot? that is a real guide)

ok, i'll check by myself...i see that asking is not accepted, thx anyway and have a nice day!

i'll check some pages back or i'll read all the 369 PAGES!!

nautilus7 · 16th December 2008, 20:09

I wrote "a few pages back". All people here are dealing with m2ts files. Someone has already posted a log file/example recently.

Blackwalker · 16th December 2008, 20:41

i'll check around, thx anyway nautilus7

Is eac3to or any of the default filters known to lower lfe channel volume?
I have been converting lossless audio tracks (THD & DTSHD MA) to 640kbps ac3. I have done a listening test, and the only detectable difference is a noticably weaker bass.

I always convert from the lossless data, not core. This morning, I tested the DTS MA track on Mamma Mia and bass is certainly stronger on the DTS track compared to my DD track. I noticed the same effect with Iron Man which was True-HD.

Would I need to rip to wavs first and apply a boost to the lfe channel only?

Cheers, Beastie.

EDIT: If I do: eac3to DTSHD_MA_Track.ts New_ac3_track.ac3

will this use the HD data or the core data as the source?

No, Aften have a LFE low-pass filter but the default is don't use.

These problems are, most the times, by different settings in players. The sources are identical (more os less).

This never solve the problem, only add more problems.

If you have ArcSoft/Sonic the HD, if you only decode with libav the core.

madshi · 17th December 2008, 14:22

Look here for more information about LFE volume:

http://www.avsforum.com/avs-vb/showthread.php?t=748147

It's a complicated topic, but as tebasuna51 says, probably caused by settings in either your player or your receiver/amp. Strange enough if there are problems it's usually DTS which has weaker bass compared to AC3. So something is funny in your setup...

Beastie Boy · 17th December 2008, 16:19

Thanks for your replies. I'm bitstreaming both codecs to my amp (Marantz SR8002) so maybe it treats the two codecs differently. Just as a comparison, I examined a portion of the lfe wave file from both the core and the HD data, and both seem to be at the same level.
I'll test playback of the core DTS track and see if there's an improvement.

Cheers, Beastie.

Beastie Boy · 17th December 2008, 17:12

[offtopic, but follow-up to earlier post]
After comparing samples, the levels for all the codecs are the same. However, after some listening tests, it seems as though my amp way overblows the LFE channel of HD codecs. Both AC3 and standard DTS play correctly but, THD and DTS-HD bass totally dominates the soundtrack. I guess I'll be sticking with AC3.

Cheers, Beastie.

73ChargerFan · 18th December 2008, 06:49

Weird, I was going to ask about low LFE also. I don't have a clue yet, though, as to what to do.

Also tried -2pass and it also failed.
