I use the last version. It's Done.

Have a nice day~~~~

Hello, I'm having trouble converting a .dtshd 5.1 and 7.1 48/24 track that I have. I have the Sonic Audio Decoder (4.3.0.169) installed but I always get an error when I run the command line.

"The format of the source file could not be detected."

Any idea why this is happening? I can play the file fine in Windows Media Player. I can upload the track (it's short--about 2:00) if anyone wants to play with it.

By the way, I just downloaded the latest version of this program today. I'm using the GUI, but I could just as easily use the command line version (since I have that too).

Yes, that's right. Unless there's a bug in the new version.
But you have a very big delay value, so you'll be able to notice if something wrong.

Are you sure it's a dts-hd file? What are you trying to do? I think it's better to test again using the cli.
Anyway, you can upload the track if it's small.

[Biggiesized]

Yes, I'm positive it's a DTS-HD file--otherwise it wouldn't have had a .dtshd extension and play correctly.

I'm uploading the 5.1 mix since it's only 20 MB. I'll upload the 7.1 longer mix later if necessary(it's about 90 MB).

EDIT: I'm trying to transcode it to .flac or .wav or even .ac3 if I can get it to work.

[nautilus7]

Your file is a dts-hd track that has only the dts core with no extensions in. This means it's a normal dts file.
Except from the "garbage" it has in the beginning and the end. That's why eac3to can't recognize it.

Change the extension to .dts and use latest delaycut (v1.3.0.0) to fix the track (remove the garbage). Then it 'll work. I guess the same applies to the 7.1 track you have.

Yes I will post a list...done with 25 titles so far (using two computers) without a single problem (Goodfellas is the exeption, but I guess the disc is corrupt. Will try a fresh disc on thursday).

I'm doing a fast check on audio sync (5 minutes from start and 15 minutes from end). The TrueHD track on Training Day was out of sync. BUT it's out of sync when played back in PowerDVD also. So I guess it's a bad authoring.

I hope to go through the whole collection before the end of the year.

Then I will move on to the Blu-ray titles. I don't really know how to handle audio delay on movies spread over multiple m2ts files yet. But I guess that's a headache to handle later on.


One thing that's bother me though is if I should use 23.976 as timecode or 24000/1001.

I can't get perfect smooth playback on some titles (don't know if the timecode provided when muxing the mkvs will make any diffrence). And I'm not sure if it's going to influence audio sync at all (tiny diffrence),

My TV (Pioneer LX608) accepts 24p. And the combination of this TV and a nvidia 8600gts (Vista 32) I can output 23, 24, 25, 29, 50, 59, 60.

When using 59 (I guess it's 59.97Hz) the audio falls behind (don't know if it's related to the 3:2 pulldown).
Choosing 23 (don't know how exact this is but I guess 23.976Hz) results in perfect audio sync but some titles stutters sometimes.

Does the timecode I set when remuxing affect this in anyway?
Right now I'm starting to believe that 23.976 gives the best result (over 24000/1001) but I'm not sure if it's just my imagination.

I know it's the wrong place for this discussion. But it would be great to hear if someone know how the timecode affects audio sync AND smooth video playback.

Where do I find delaycut v1.3.0.0? Can just find v1.2.1.2.

[nautilus7]

I have to ask this, sorry...
Does such thing as 23,976 really exist? Where does it come from? I believe it's 24000/1001(23,9760XXXXX) that is called 23,976 in sort. Nothing more. But maybe i just said a nonsense.

v1.3.0.0 is made by madshi (not the original author of delaycut), thus it can be found on this forum, in delaycut thread (use search).

EDIT: here's the link http://madshi.net/delaycut.rar

Don't know. 24000/1001 is the standard for what most titles are mastered at I think. But I guess it's a rounding thing. And that's why I ask. If it will make any diffrence at all on smooth video playback and audio sync.

[nautilus7]

Exactly. So when 23,976 is used instead of 24000/1001 is wrong. Of course the difference is tiny, but there shouldn't be a debate whether the one or the other should be chosen.

Exactly what I think. But why does some titles playback perfect when timecode are set to 23.976 but NOT when set to 24000/1001. That's what I can't accept. One example is The Last Samurai HD DVD.
I guess I have a bad understanding in how the frames are handled...

[nautilus7]

You mean .mkv? Don't have a clue. Maybe an audio problem.
I have this hd dvd, maybe i try something tomorrow.

Yes mkv... Syriana is another title with the same problem (?).

The differerence is extremely small. But the more "correct" value is 24000/1001 and that's what the latest eac3to version is using.

But audio sync is correct? This could be a software setup related problem.

23 and 59 sound strange to me. It's strange to name "23.976" as "23". But who knows... Maybe PowerStrip would be worth a try for you?

You mean the video stutters sometimes? Is this with MPEG2, VC-1 or h264 (or with all three)? Maybe your PC is not fast enough to handle some of those movies?

You set a timecode when remuxing? How/where?

[buzzqw]

just playing with this tools.. great work!

just to add to wisth list
output to stdout (for using with neroaac/lame/oggenc...)
parsing of ts files

thanks!

[nautilus7]

I was about to ask for mp3, aac, vorbis support.

I know this tools focuses on HD DVD/Blu-ray audio, but these formats are useful to convert the audio commentaries to.

[madshi]

Which format do these tools expect via stdout?

[nautilus7]

I guess the q is for buzzqw. Don't know what stdout is anyway.
