eac3to - audio conversion tool

[Sephiroth0000]

To the countless geniuses on here I have a question,

I currently use EAC3TO for pretty much everything (even converting the EVO to MKV). However I would like to know what video codec is used within the MKV container and if it is possible to use H264 as the video codec within the MKV.....anyone got any advice?

eac3to muxes the existing video into a mkv container, there is no transcoding. If h264 goes in, h264 comes out. Same for VC1 and MPEG2.

Anyway to force out H264?

Cheers Beastie really appreciate this.

If the source isn't h264 (as can be seen in eac3to stream listing) then load the mkv into meGUI avisynth script creator, or RipBot264. Then convert the video to h264 and mux with your audio into the container of your choice.

Sorry, but re-encoding is the only way to change video codec, and it can be very slow. It usually takes my machine 20-24 hours for 1080p video.

Cheers, Beastie.

No no no you get me wrong....I want it to be H264 within an MKV container. The file im starting with is EVO.

Yes, yes yes, I am understanding correctly

If the EVO contains VC1, then the only way to get h264 into an mkv file is to re-encode. How are you playing the file? VC1 works perfectly well in mkv. Do you need h264?

Cheers, Beastie.

That's exactly what Beastie described. It sounds like you don't know exactly what "h.264 within an MKV container" means. EVO and MKV are containers. An EVO file ripped from an HD disk might have video encoded to either the MPEG2, h.264, or VC-1 video standards. eac3to can take your video from an EVO container and put it in a MKV container but it can't transcode the video from VC-1 or MPEG2 to h.264. Like Beastie said, you would have to use an encoder, like meGUI, to transcode an EVO file's contents.

I've been backing up my blu-ray disks to mkv containters using eac3to (latest build).

I've had plenty of success with PCM audio tracks, and even extracting DTS Core audio from DTS-HDMA tracks. I'm now trying to convert DTSMA tracks to FLAC format using the Sonic decoder before muxing to MKV. Trouble is, when eac3to starts the job, it just seems to hang. Plenty of CPU activity, but hardly any disk I/O. Here's any example of the output if I use eac3to to demux;

C:\Temp>eac3to 00001.m2ts 1: 00001.mkv 2: 00001.flac
M2TS, 1 video track, 6 audio tracks, 1:31:50
1: h264/AVC, 1080p24 /1.001 (16:9)
2: DTS Master Audio, 5.1 channels, 24 bits, 48khz, -9ms
3: DTS, 5.1 channels, 24 bits, 768kbit/s, 48khz, -9ms
4: AC3, 5.1 channels, 384kbit/s, 48khz, dialnorm: -27dB, -9ms
5: AC3, 5.1 channels, 384kbit/s, 48khz, dialnorm: -27dB, -9ms
6: AC3, 2.0 channels, 224kbit/s, 48khz, dialnorm: -27dB, -9ms
7: AC3, 2.0 channels, 224kbit/s, 48khz, dialnorm: -27dB, -9ms
[v01] Extracting video track number 1...
[a02] Extracting audio track number 2...
[v01] Muxing video to Matroska...
[a02] Decoding with DirectShow (Sonic Audio Decoder)...
[a02] DirectShow reports 5.1 channels, 24 bits, 48khz
[a02] Applying RAW/PCM delay...
[a02] Encoding FLAC...

There's no progress bar or anything. I normally use xport to split the raw video/audio, but that doesn't make any difference even if I just try and recode the audio.

Here's the output of eac3to -test

D:\Movies>eac3to -test
Nero Audio Decoder (Nero 7 or older) doesn't seem to be installed
Sonic Audio Decoder (4.2.0.102) works fine
Haali Media Splitter (2008-3-29) is installed
Surcode DTS Encoder doesn't seem to be installed
MkvToolnix (v2.2.0) is installed

CPU is a dual-core Athlon. Am I missing something here?

I don't know why, but this is the problem. Update to version 4.3 and you'll be fine.

I am aware of what video codecs are and how they work. I just thought maybe EAC3T0 could of given me that option....apparently not. Thankyou for your input though.

Thanks for the tip. Any idea where I can get this from now? PM would be appreciated.

[nautilus7]

I am working on it!

eac3to does NO video re-encoding, only audio.

Hello madshi

I´m using a self written DOS script. Now I have the problem that eac3to founds gaps and want me to recall script line. With this eac3to did´nt find the file, DOS did it:

IF EXIST "*ac3*english*5*1*.gaps" (
EAC3TO "*ac3*english*5*1*.ac3" english.ac3
)

But if I rename it for example to english.gaps and english.ac3 eac3to did´nt find again the gaps file.

In DOS I can use the "*" but eac3to ignores it. Can you give me an alternative joker?

If you have DOS extensions you can use the FOR command:
FOR %%V IN (*.gaps) DO eac3to "%%~nV.ac3" "%%~nV_2.ac3"

Now DOS supply the full name to eac3to.

Version 2.46 didn't seem to add FPS value to MKV header for a VC-1 HD-DVD (Syriana). Playback was jerky.

Version 2.36 did (yes it's been that long since I bought a disc..), and playback was smooth.

Am I missing something? Sorry, I'm 80 pages behind, I've skimmed them, but things move so fast. I've read about some pulldown changes, but I don't think that's the issue (?).

Thanks

Mark

EDIT: I tried it again with 2.46 and the FPS were added. Sorry, please ignore.

[Thunderbolt8]

hm I remuxed the monster blu-ray with 2.46 (which is VC-1 as well) and I have no playback problems

[nautilus7]

I also used v2.46 for H.264 and Mpeg-2 video recently. Fps value was written to the mkv header.

Today, i've met with a problem. The default audio is Japanese on Red Dragon HD-DVD.
Normally i directly demux audio of HD-DVDs with EAC3to but it selects the first audio. (AFA i understand)
I gave it a go with TSRemux which seems to recognize some audio files but after demuxing , TSMuxer doesn't accept this re-created ac3 file.
Is there any way to select any audio with eac3to?

[Thunderbolt8]

of course, when specifying the .evo file(s) or also the playlists with corresponding evo files you can manually choose the single track with 1: 2: 3:... and then choose what to do with it
