The 1997 OT Special Edition Trilogy Preservation Standards Thread (* unfinished *)
Time

I had an idea today....what if someone took the "DTS" audio from the 5 Star DVD "import" collection and somehow used it to trim and time the actual DTS Theater audio we've got available....is this idea feasible?  I mean, it would at least be timed to the LD video ...... so it would make sense that one might be able to match the two if they were audio savvy enough, no?

Creating an LFE channel with Sony Vegas???

Vegas is great for creating a 5.1 track if you want to sync the track to video. Although you can't export it as a DTS 5.1 file, you can export each track separately as mono uncompressed wav's and import into a DTS encoder. But if it is a 5.1 track then shouldn't you have 6 PCM files and not 5? Or is this what you are asking, that you need to create a LFE channel from scratch?

Yes....I believe the LFE for DTS audio is supposed to be extracted from the rears.

Creating an LFE channel with Sony Vegas???
Time

Calling all audio-saavy folks out there, I want to learn how to use Sony Vegas to create an LFE channel for the DTS audio I have.

The decoding I did got me 5 channel PCM files.  The SE audio should be DTS 5.1, the PT audio should be DTS-ES.

The other question I have is this....is Vegas good for this or should I be working with something else to get all the channels set properly for use with other video projects?

Thanks in advance....I hope this wasn't too confusing.

:)

Brute Force was tried and failed. The actual encryption algorithm was found to be weak so figuring out encryption key was easy. A singular .exe program was compiled for the specific discs of audio as each set probably has their own separate encryption key so it's a 1 shot deal.

The lucky part ..... the encryption didn't change throughout the soundtrack, other wise I'd only have a piece of the puzzle.

At this point, I now have PCM audio from the encrypted .aue files. This has been a cool journey but it's not over. We obviously are going to do other testing to see what can be done, if anything, to create something more universal for this subject matter.

Thanks to my partner Maxim in this. He was nothing but cordial, understanding, helpful, and 100% gracious.

The cool thing about this .exe program is that I can use it to convert the .aud files straight to 5 channel PCM so I'm going through the discs I do have and redoing the reels.  They will still have to go through some processing but I'd think this is a better way to go to keep the quality.

Interesting stuff! I read somewhere that the encryption would let you play the first 2 minutes or so with the in_aptx plugin (as you would an AUD) and then you would get garbled noise afterwards. You say the encryption has been cracked with a custom executable, so was achieved without the use of the 6D and ripped straight to PCM? Are these PCM files in the format of a single 5-channel PCM file for each reel? If so, are the channels in the correct places?

Sorry for all the questions, but this is all very impressive and exciting! Very well done to you and your partner!

ALL the work was done without a DTS Cinema Processor.  All software based.  The executable is actually based on the dts.exe that comes with the discs.  So, as far as I know, the channels are all coordinated as they would be straight from the 6D.  It is a single 5-channel PCM file for each reel.  I re-did all the ones in my collection.  The .aue is a bit different because each has a key for decryption .... the .aud's do not.  I had to redo my Star Trek DTS audio I have as well because I figure this would be better.

When I get the ROTS upload set up I'll send you the link.  You should be able to determine if they're all in the right places but I have no reason to believe otherwise at this point.

Cheers.....and yes, Maxim did an awesome job with all the resources I provided him.  He is the king for sure.

I have some awesome news......

I NOW have the PCM audio for Ep. III.  At this point I do not have permission from my partner to go into detail but we've been working in tandem quietly so that this project could happen or fail without too much pressure. 

He gets ALL the credit for the work as he figured it out ..... I just supplied the source material and miscellaneous stuff for him to work with.

Certainly an early X-mas present.

:)

Congratulations! Well done both of you.

Thank you all kindly.  And, for a brief explanation of what happened... 

Brute Force was tried and failed. The actual encryption algorithm was found to be weak so figuring out encryption key was easy. A singular .exe program was compiled for the specific discs of audio as each set probably has their own separate encryption key so it's a 1 shot deal.

Cheers to ALL of us ....... the circle (of DTS audio) is now complete.

That's excellent news! Any word on how/when we can get these files?

I will make sure that those who'd like access to the audio get it ......  :)

Help: looking for... OT Unaltered/Laserdisc versions? (I'm a newbie needing help!)
Time

Hello and welcome to the forum.

I am certainly sad to hear that you had to "pay" for Laserdisc captures on eBay.  You won't find anything for download like that here but I bet if you keep your attention to projects going on in this section of the forum you're bound to find what you're looking for.

Cheers, and enjoy your time here.

When/Why did you become an OT purist?
Time

I became an OT purist the day I saw ROTJ in the theater for the first time after seeing the other two.  At that point I was like "the Star Wars Trilogy rocked".  That was the "Trilogy" ..... that was IT.  I was like 12 when that happened.

The SE came around years later and made me re-appreciate them even more though I will say that as a standalone anniversary presentation I was and still am cool with the 1997 SE.

That is all ...... :)

The Japan LD's are spread out over 2 discs as well.  The 1st pressing is the Silver Box like the Widescreen VHS Box.  The 2nd pressing sports the new artwork and drops the Special Edition moniker.

 

PAL ANH and ESB are on one disc (about 1 hour per side). ROTJ is on 2.

EDIT: My bad, by one disc, I mean a disc each! They'd have to do a 200% speed-up to fit both films on one disc, which would be amusing but very impractical!

The PAL set is in a silver box too, similar if not the same to the first pressing of the Japanese set. I saw a Japanese silver-box set on eBay a couple of weeks ago, and noticed is had the 5.1 AC3 audio, which the PAL laserdiscs don't have. Does the Japanese set you have also have the 5.1 AC3 too?

Yes......
