If you go back a few posts you can see a graph I posted showing that the bitrate will be to high.

Well then, that might well be what's causing the synch errors in the PCM tracks that people are getting. When Lucasfilm was setting the video bit-rate they didn't factor in a PCM soundtrack being used. This means that a DD 2.0 version of the PCM soundtracks with a bit-rate of 448k (the highest that DVD will allow) will have to be used when substituting the official default soundtracks with these higher quality ones. This will still sound much better than the 192k bit-rate they used on the official DD 2.0 soundtrack.

As I posted earlier, the full size .wav file from the ESB .rar files that were posted by boba feta wouldn't play on Winamp. So I had an idea, perhaps if I put the ESB .wav file into a flac file (as the A New Hope PCM soundtrack files had been in flac form when they were posted by boba feta) and then back into a .wav file that might help.

In theory that really shouldn't change anything, since your basically just compressing the .wav file, but in a lossless format that is playable as a flac sound file, and then uncompressing it back into what it was. But the Flac files from A New Hope (and the .wav files from them after uncompressing them) that boba feta posted worked fine with winamp, so I thought I'd give it a try. Sure enough, after compressing the ESB .wav file into a big flac file, it played fine as a flac file on winamp, and then when I uncompressed that flac back into a .wav file, it also played perfectly in winamp.

I'm not sure why this is the case, but when I was compressing the .wav file into a flac file, I saw a message that said something like "1 general error". But the process went ahead just fine and finished. And the files, both flac and .wav from the uncompressed flac file seem to play perfectly in winamp. I checked the sizes of the two .wav files, the one straight and unaltered from the .rar files boba feta posted, and the one I got after compressing the original .wav file into a flac file and then uncompressing it back into a .wav file. And there is a tiny difference in file sizes, the .wav file that was in flac form before being uncompressed is about 1k smaller than the original .wav file. The only thing I can think of is that perhaps the original .wav file had a missing tag or something in the file, and this is what caused the error with winamp, but when putting the file into flac the form, the flac compression program automatically added the missing tag and thus eliminated any problems that winamp might have playing the file from then on.

What do you guys think, any ideas on what might have happened with this .wav file and why it works after being put into flac form and then back to a .wav file?

I just downloaded the RotJ .wav file and was having the same trouble as with the ESB file. I used the flac program again and sure enough it fixed the problem just like I said in the previous post. This time I took a screen shot of the DOS box from within which the flac program runs, so I could type up any error messages that might help us to figure out what's wrong with the original .wav files. Below are the error messages that showed up in the DOS box while the file was being compressed from the original .wav file posted by boba feta and put into a flac file.

ROTJ '93 DVD.wav: WARNING: skipping unknown sub-chunk 'bext'
ROTJ '93 DVD.wav: WARNING: skipping unknown sub-chunk 'minf'
ROTJ '93 DVD.wav: WARNING: skipping unknown sub-chunk 'elmo'
ROTJ '93 DVD.wav: 100% complete, ratio=0.443ROTJ '93 DVD.wav: WARNING: skipping unknown sub-chunk 'regn'
ROTJ '93 DVD.wav: WARNING: skipping unknown sub-chunk 'ovwf'
ROTJ '93 DVD.wav: WARNING: skipping unknown sub-chunk 'umid'
ROTJ '93 DVD.wav: Verify OK, wrote 672631682 bytes, ratio=0.443

Tag - Automatic Tag from filename

C:\ROTJ '93 DVD.flac

Tag guessing failed.
Format: FLAC
Details 48000 Hz Stereo, 137 kbps, playtime 02:11:41


And then several lines below that it said something like " General Error: 1 "


Do any of you audio experts recognize what these error messages mean and why they happened? And do any of them have any chance of meaning that the .wav file after being compressed by this flac program, and having these error messages come up, and then uncompressed back into a .wav file will no longer be perfectly synched to the ESB and RotJ video for some reason?

Mallwalker, Is there any way you could upload ac3 rips of the dark-sega versions of the pre DC mixes of Empire and Jedi. I'd like to synch those with the GOUT if possible.

You get to many frame drops because the total bitrate is to high I guess. The video needs to be re-encoded (with a maximum bitrate of something like 8200 kbps).

I compressed the video and it's still giving me the same thing. What's the deal? I've tried with several different kbps .ac3 files, from 448 down to 224, and I'm finally giving up and trying 192 kbps just so I can mutiplex it and hear the damn mix for once - but if that doesn't work, then I don't know WHAT the problem is, because then the bitrate will be the same as the original DVD. . . .

I'd suggest using some other software, I've had no problem with Encore.

Belbucus or boba feta: Have you been able to figure out why the PCM .wav files are causing those error messages (listed in the post above) when compressing them into flac files and why they didn't want to work in winamp until after going through the flac compression and then uncompressing them?

As far as the bit-rate issue, I certainly wouldn't want to lower the bit-rate of the video on the 2006 Star Wars DVD set, we need all the video quality we can get. Better to take the PCM soundtrack and convert it into DD 2.0 with a straight 448k bit-rate. That will sound much closer to the PCM track than the default DD 2.0 soundtrack and it will not cause any problems with the going over the max total bit-rate allowed for DVD.

If you are re-encoding video, this makes a good argument for upsizing to Anamorphic dimensions while you're at it. Another thread covers this in detail.

Well, nothing seems to work muxing with IfoEdit or MuxMan ... I was able to burn it with TMPGEnc DVD Author, but of course there are no subtitles, menus, etc now ...

Anyone have any suggestions to mux the m2v, .ac3 and .sup files together in such a way that I can replace the original VIDEO_TS files of the DVD and keep all the original menus, etc? Once they're muxed into VOBs I can do it, but I can't get it muxed into VOBs - I keep getting error messages. I've tried with the full video and ac3s of 448 down to 192 kbps, and the same with compressed video ... nothing works!

I'm also working with anamorphic-converted video ... would that cause these issues?

Ash, have you tried using restream to remove sequence end codes? This might solve the issue.

A couple of questions regarding the status of all this.

It is my understanding that ANH HAS been synched successfully by some, and it's ESB and RotJ that are presenting problems, correct?

Boba feta, when you say you've had no problem using Encore, are you saying you HAVE been successful in applying it to the latter two?

I have not muxed ROTJ (although I have done a rough measurement of the delay offset.)

I have successfully muxed ESB, using a delay offset of 45,528 samples (0.9485 sec).
I watched it, and didn't notice any problems. It remained synchronized through to the end.

I have successfully muxed STAR WARS with the '93 PCM (first 15 minutes only) and with the '77 Dolby Stereo (entire film).
No problems with either, but the offsets were different:
48,851 samples + "DC48 DVD.wav"
48,743 samples + "DS48 DVD.wav"

However, in practice you must take into account the “fuckwit factor”. Just talk to Darth Mallwalker…

They should be identical. Once lined up, running side by side, I used the first sample of the '93 PCM GOUT as the reference for both.

By what means are you determining your offsets?

Are these files still available please? I can't seem to download any of the Star Wars ones.

Also as I understand it the Dolby Stereo 35mm mix (taken from the 1985 LD) is an analogue transfer rather than a pure digital copy like my 1989 LD transfer. Anyone know what equipment was used for this?

Cheers,

The monomix is still on pause, awaiting the resolution of some synchronization anomolies with the reference video. I anticipate having it back on track soon.

Okay ... I must be doing SOMETHING wrong ... could someone give me a short tutorial of what they did to acheived successful results? I'd like to make a set of .VOB files that are identical to the original ones with the 77 theatrical stereo .ac3 in place of the 93 English mix on the DVD.

Perhaps it's in the way I converted to .ac3? I used besweetGUI ...

I'm using Audacity to look at the waveforms (Windows version running under WINE, since I don't have the required wxWidgets to compile native Linux version).
Here's what I see:

DC48

DS48
http://img99.imageshack.us/img99/2220/ds48po6.png

As you might guess by the relative amplitudes that's the first, louder DS48 file. But the second "DS48 RL" has the same peak in the same position 0:27.798500

The difference is 0.002250 or 108 samples.





seventiesfilmnut, send a PM if you still can't get the filefactory links. They appear to be working fromt where I sit.

You are assuming these are sample accurate. They are not. They originate from 2 entirely separate analogue sources and therefore could not be. My tolerance in synching these by ear was in the neighborhood of 10 samples - as the Dolby Stereo track had a constant tendency to randomly drift ahead and behind the DC48 track. I was most critical when audio had to exactly match to something in the picture – like lipsynch. If you were to examine waveforms at several different points and find a consistent offset of minus 108 samples with respect to the DC48, then I would say there is a problem. Otherwise, I would consider the coarse offset to be the same for both.
