Is there an E-AC3 to AC3 Converter?

[SeeMoreDigital]

I've finally got round to backing up some of my HD-DVD disc's for storage on my media files server.

I ran the disc's thru' AnyDVD HD 6.6.4.2 and then used TSmuxer to re-mux the main .EVO files to the .M2TS container. However they all contain (that pesky) 6Ch DolbyDigital Plus audio, which is causing compatibility issues with my Onkyo TX-SR607 surround sound amplifier.

Does anybody know if anyone has got around to developing an application that can convert elementary E-AC3 audio streams to elementary AC3 audio streams?


Cheers all

Eac3toI've looked at "EAC3toMore GUI" and "Another EAC3to GUI" and I have to admit... I'm completely lost :eek:

eac3to can decode the track directly from the EVO. You can just use a command line like:
eac3to "C:\Path\to\HDDVD"
which will display a list of titles.
Then you select a title, for instance the first:
eac3to "C:\Path\to\HDDVD" 1)
This will display a list of tracks. Then you'll simply have to tell eac3to which track to reencode, for instance track 4 at 640 kbps (the default for AC3 is 448 IIRC)
eac3to "C:\Path\to\HDDVD" 1) 4:"D:\temp\track4.ac3" -640

I've already converted the .EVO files to .M2TS files (which includes deleting the non-required audio and subtitle streams).

Is there nothing that will work with "elementary" E-AC3 audio streams?

[nurbs]

In that case point eac3to at the m2ts file. This will display the tracks of the file. Select the one you want to convert and remux the result. If you have a demuxed eac3 file try pointing eac3to at that. Don't know if that's supported, but it's worth a try. It works with normal .ac3 files.

With "elementary" E-AC3 audio streams you can use:

eac3to input.eac3 output.ac3

Thanks guys...

I can't see how I can do either of those suggestions in "EAC3toMore GUI"...

Indeed, the EACtoMore "GUI" is so large on my 1280x800 screen, I can't even find/see the "start/launch" button... If it has one at all.

I guess it would be easier to just use the command line.

I guess it would be easier to just use the command line.Sadly, I'm cluless with command lines :o

EAC3toMoreGUI is a complex GUI.
In old version you need:

- Sources:
Add Source file

- In 'Eac3to audio' tab:
Input file: select one more time the source
File name: put the desired output filename
Save as Type: ac3

- 'Run Command Line'

Edit:
Maybe you can try 'UsEac3to (http://forum.doom9.org/showthread.php?t=145574)' GUI more simple for this.

- Input or Drag&Drop the eac3 file
- With 'Output format': ac3 (default), click 'Add'
- 'Run Command Line'

As a test, I've just converted an 1536Kbps E-AC3 stream to an 448Kbps AC3 stream and a 640Kbps AC3 stream. I'm muxing them to the video stream right now.

I'll report back how well the finished plays via my XtreamerPro.

Thank-you very much :)

You are welcome.

As a further experiment... Yesterday I used your applications "Change to 23.976" option on a two hour movie... It worked perfectly :)

As you've discovered, eac3to is multitalented. :)

It's actually one of the most critical tools for manipulating modern HD formats. With eac3to, DGIndexNV, AVISynth, x264, TSMuxer and MKVToolnix you can do just about anything you want or need. Thrown in SupRip, SubRip, and Subtitle Workshop and you have the whole thing.
