Can the final filesize of a FLAC track created by eac3to tell something about the quality?

I just compared two tracks from two diffrent releases of a movie. The FLAC created from the LPCM track is about 0.9 GB in size. And the FLAC created from the DTS-HD High Resolution track is about 2.2 GB.

Number of channels, bit depth and sample rate is the same. (The length of the LPCM track is about one minute shorter. Shorter credits)

[nautilus7]

Most probably you're mistaken about bitdepth. Which movie is this? And which releases? Can you post the logfiles?

Generally, bigger size, better quality.

The Sixth Sense. US vs. German.

I'm pretty sure eac3to said that the DTS-HD High Resolution track was 16 bit before decoding. But after looking at the spec of the created FLAC I see that it's actually 24 bit.

[Thunderbolt8]

ive also converted these 2 and can say that the sizes are correct. afaik DTS-HD gets patched to 24-bit for some reason, thus the size increase. the LPCM track is only 16-bit, thats why it is so small.

[nautilus7]

DTS(-HD) dynamic range is equivalent of 24bits, thus patching bitdepth. If you don't want that you can use the undocumented switch -dontPatchDts.

as all the ape films have new BD+ protection which hasnt be solved yet, i suppose it is an issue with how you extracted the m2ts files. have you seen the results of the other ape films you say worked ok?

Will update the first post. But I'm wondering: Is there a specific reason why you want to use r8brain instead of SSRC?

Can the final filesize of a FLAC track created by eac3to tell something about the quality?
It gives you a hint about the bitdepth. A higher bitdepth does not always have to mean that the quality is better. So you can not look at the file size alone. E.g. I'd consider a 16bit lossless track to be ever so slightly better than a DTS-HD High Resolution track (which is decoded by eac3to to 24bit).

I'm pretty sure eac3to said that the DTS-HD High Resolution track was 16 bit before decoding. But after looking at the spec of the created FLAC I see that it's actually 24 bit.
The DTS bitdepth reported by eac3to is a header field in the DTS track which tells us which bitdepth was fed into the DTS encoder. For lossy tracks this is just an information and has no use whatsoever for the decoder. So eac3to decodes to 24bit instead. For lossless tracks the situation is different, though...

Anyone having problems with this title?
This could be either a ripping bug in AnyDVD HD or it could be an authoring fault. I'd suggest reporting this problem to the AnyDVD HD guys and see what they say. I'd say there is a good chance that this is a bug in AnyDVD HD, but I can't say for certain...

I tried installing Nero 7 Showtime only from the Ultra package, but eac3to says "The Nero decoder doesn't seem to work, will use libav instead". How can I install the filter correctly? Better yet, can I install the filter without installing any Nero components? (such as extracting the nessesary files and registering them)

You need the BD/HDDVD plugin installed too. I think you can have just Showtime installed and have eac3to work with it.

[odyssey]

Also if I'm just using it to transcode regular DVD AC3?

Nero would be the preferable decoder, but libav does a good job too, which comes packaged with eac3to.

You need the plugin so you can use the decoder. It's irrelevant of the source you're using.

eac3to v2.76 released

http://madshi.net/eac3to.zip

* "-slowdown" now works to convert 24.000 movies to 23.976
* "-speedup" now works to convert 24.000 movies to 25.000
* option "-xx.xxx" (e.g. "-24.000") sets the FPS of the source track
* option "-changeToXx.xxx" (e.g. "-changeTo23.976") changes video/audio FPS
* modified FPS information is written to video bitstream (VC-1, MPEG2, h264)
* demuxing with FPS change option now activates audio track transcoding
* SSRC resampling parameters modified slightly to reduce steepness and ringing
* fixed incorrect h264 movie slowdown gap/overlap complaints
* fixed DTS-HD High Resolution bitrate calculation
* dithering is now done differently per channel
Let me explain the new FPS changing options:

(1) If you have a source which contains FPS information, you don't need to tell eac3to which FPS the source has. E.g. if you feed eac3to a m2ts, TS, EVO or VOB file with a video track in it, eac3to will know which FPS the video and audio tracks have. So in this case you can just use "-slowdown" to convert both 24.000 and 25.000 movies to 23.976 fps. Or you can use "-speedup" to convert both 23.976 and 24.000 movies to 25.000 fps.

(2) If eac3to does not know the source FPS (which is usually the case if you feed eac3to with a demuxed audio track), you can still use the "-slowdown" and "-speedup" options. If you do that, eac3to will apply 25.000 -> 23.976 (slowdown) or 23.976 -> 25.000 (speedup) conversion.

(3) If you want to do any funny conversions. E.g. if you want to convert a 25.000 source to 24.000, you can use the option "-changeTo24.000". If eac3to knows the source FPS, that's all you need to do. If eac3to doesn't know the source FPS, you should do "-25.000 -changeTo24.000" to do a 25.000 -> 24.000 conversion.

(4) Generally, if the source is a container which contains both video and audio tracks, doing either "eac3to source -demux -anyFpsChangeOptions" or "eac3to source some.mkv -anyFpsChangeOptions" will result in eac3to doing FPS conversion for all audio and video tracks. Audio tracks will be transcoded in this situation. Lossless tracks will be transcoded to 24bit FLAC. Lossy tracks will be transcoded to 640kbps AC3.

(5) Video FPS changes will as usual not only result in adjusted MKV timestamps. eac3to will also automatically adjust the video bitstream itself to reflect the FPS value change.

btw. if I slow down an audio track with delay, whats done first: the delay applied and then the track is slowed or the other way round (the message order on screen is first the fps conversion and after that applying the delay)?

Good question. Just checked: Resampling/slowdown is done *before* delay, which I think is wrong. Will change that in the next build.

I'm wondering: Is there a specific reason why you want to use r8brain instead of SSRC?
This is first time I'm using eac3to to slowdown/speedup audio (usually I use SForge for this) and I just wanted to compare speed of these two methods (SSRC and r8brain).

[Thunderbolt8]

should be 1h30min41s (is 1h30min36s), but have to test with the audio first. maybe its allright.
nope, its unfortunately not. seems to vary a little, at the beginning its at least closer to being correct as towards the end.

for those 2 clips it always seems to be the video which is wrong, when you count the number of seconds for original 25fps audio for both movies and then calculate it to 23.976 fps, then the slowed down audio track seem to be fine.

tested the robocop without -slowdown, and its already wrong then, the video duration:

1:38:57 original .ts length
1:42:37 remuxed .mkv without -slowdown
1:43:11 supposed video length for -slowdown
1:46:XX video length with -slowdown


same for cube without -slowdown:

1:26:58 original .ts length
1:26:53 remuxed .mkv without -slowdown
1:30:41 supposed video length for -slowdown
1:30:36 video length with -slowdown

at least here it seems the difference of 5 seconds seems to be stable after the slowdown process.

Appreciate this might be a little of the beaten track but just wondering whether the -slowdown or -speedup settings can be used to help produce .ts files which will auto-trigger 24p settings on a TViX player.

I use eac3to to demux my Blu-ray disks and have to say it works brilliantly. However, if I mux video and audio streams into an .mkv file my TViX player autoswitches into 24p mode. If I mux exactly the same video and audio streams into a .ts file it doesn't, unless the video source is MPEG2 which most recent Blu-rays aren't.

The reason I want to use the .ts format is that the TViX plays this format well as opposed to .mkv's which have video stuttering and audio dropouts.

Is there a "header" in the .ts container that can force 24p mode? Can eac3to create that header?

There's a "FPS" like field in the MKV header. But for TS files there's no such field (at least as far as I'm aware). Still the TViX could detect the right framerate by looking at the video bitstream. It seems that it does that correctly for MPEG2, but not for VC-1 and h264. There's nothing I can do about that. You'll have to ask the TViX guys to add support for that. It's not too difficult to realize. If they need help about how to parse the VC-1 and h264 bitstream, you can tell them to contact me...

It's irrelevant of the source you're using.No it's not. odin24 claims that I need BD/HDDVD plugin installed in order to decode AC3 audio, but It's logical to think that it's not needed when it's JUST for old AC3, not EAC3!

Also, noone answered why the filter didn't work - I already installed Nero Showtime 7, why would it not work?

I suggest reading the answers you 're given more carefully.

The 1st post says that you need nero 7 and the plugin. That's all it says. And that should be enough to understand that you need both. Period. You need both so you can use the nero decoder. What you will do it doesn't say much to eac3to.

As additional info, you can find (by searching this trhead or the wiki) that you need only showtime from the whole nero package and you also need nero 7.8.5.0 or later nero 7. The plugin is necessary in any case.

I suggest that you stop flooding this thread with comments about a question which has already been answered in 3 different prominent places:

(1) The very first post in this thread.
(2) The eac3to help text.
(3) Several direct user replies to your question.

All of which say the same (correct) thing.

@madshi,
I was wondering if you could provide logging at the play list level please? When running eac3to on a folder which lists the play lists, the -log does not work. Once you use -log, it processes similar to "eac3to bdmv" rather than "eac3to folder" which is a bummer. I can pipe the output of the play list to a file, but it's back to having to clean up those files from all the extra CRLFs.

Also, one other request if you have time. When I'm running an instance of eac3to that's extracting or whatever and then run another instance just to log and get info about another title, the -log doesn't work. It seems to just copy what's already there from the first instance. It would really be helpful if the logging is done independently in each eac3to command. Thank you so much.

after adding -sonic, all was fine!

After your fixx using the 5.1 from the "-core", the arcsoft-decoder is "internaly" still "feeded" with the 7.1 information, i asume.

So the "-core" Option doesn´t work with arcsoft-decoder, only with Sonic at the moment.

[nautilus7]

Sonic can't output 7.1 (is limited to 5.1 in this case) that's why it works.

[himan2001]

i know it, nautilus :)

but is still internaly false reported to the arcsoft :)

Madshi,
I didn't even remember there was a wiki (http://en.wikibooks.org/wiki/Eac3to) under development.
Would you please add a link to it in the first post?

[nautilus7]

Wikibooks is a place where everyone can contribute. The fact that i started it, doesn't make it my property. Plus i haven't much time lately so it's up to other eac3to users to continue the development, so it doesn't stay "under construction" for a life.

Well apprearently it's not clear enough.

Also you need to update the wiki links (they are broken). I have searched all over the net, but yet to find the plugin package you all talk about.

Well apprearently it's not clear enough.

Also you need to update the wiki links (they are broken). I have searched all over the net, but yet to find the plug-in package you all talk about.Can you find anywhere in Nero site some info regarding how to buy nero 7? No, because both nero 7 and the plug in are discontinued now (the plug-in is included in nero 9 actually).

Is there any difference in a AC3 file created from a DTA-HD MA 7.1 and a 5.1?

I have so far created a AC3 5.1 640kbps file straight from the DT-HD MA 5.1. Now with a DTHD MA 7.1 am I better to extract the DTS core and create a AC3 5.1 from that? I only ask as I have just "AC3 encoding does not suport back channels, will mix them into the surround". Will that make the surrounds different?

[nautilus7]

One thing is the extra channels.
But another more important is that in one case you use the master audio tracks as source (lossless) and in the other you use just the lossy dts core.

[bigotti5]

Seems there is a bug in eac3to.
Tried to concatenate some mts files from my Sony AVCHD camera.
Video presentation order:
BBIBPBPBPBPBPBBIBPBP...
Stream order:
IBBPBPBPBPBPBIBBPBPB...
Two leading B-frames encoded using only backward prediction misleads eac3to to assume -80 ms audio delay.
First audio PTS: 93600 - 00:00:01:040
First I-Frame PTS (first frame stored but third frame shown): 100800 - 00:00:01:120
First B-Frame PTS (the first frame shown): 93600 - 00:00:01:040

You can dl an example here (http://rapidshare.com/files/165110840/sony_mts.rar.html)

I suppose my point is are these extra channels going to cause audio problems for the rears as the channels don't exist.
