Impressive...............most impressive.  I AM excited.

Thanks for the preview Lee.

 
Thanks Jetrell! :D

Hey Lee, I had chance today to have a look through your THX ANH preservation, and it looks pretty sweet.

I upscaled it via my PS3 for further enhancement and it was awesome. ;-)
Thanks for the feedback Rockin and who says LaserDisc is obsolete? LOL

ColinK said:

Lee, are there any 'extras' on these LDs? Will you be doing them too?
Neither the French Audio or Coffret set had any special features on the LaserDiscs, so there was nothing to include. ;)

zombie84 said:

Your Technicolor version is looking pretty fantastic. What/how did you use to correct it and when is it coming out?
Thanks for the kind words Zombie84 its really all your fault I am doing this in the first place, if you hadn't started your GOUT Automated Color Correction thread I never would have thought of doing this. ;) I am about to start a new thread for this project so if you dont mind I will answer your question in my opening post. :)

Just downloaded your ESB and it looks great. One question though. What audio did you use for this? There is something really strange going on with the audio. It has a warbling effect and it is really noticeable during any music.  Did you try to stretch the NTSC 5.1 to fit with the PAL framerate to keep the original pitch? Also the centre channel sounds very hollow as if it was recorded with a mic in a room. It just sounds very "boxy", if you know what i mean. It's a real shame because it's nice to have a laserdisc preservation of the '97 SE, but i'm afraid the problems with the audio are a deal breaker for me.

I think he used DE's LD 5.1 rips, thanks Ady for confirming what I suspected, I did not want to download any of these until there was feedback, I read that he sync'd these files up so fast and could NOT figure out how he did it, because I was using NTSC LD's and these did NOT sync right out of the box, they needed work, and it took a lot of time, plus I was weary about putting an LD rip on a DL DVD, seems a bit much to me, but Thanks again for the feedback, it really helps out a lot.

Hell it was even more work to get DE's LD 5.1 rips in sync to the DV Broadcast versions I did, but it was well worth, those files sound SO GOOD when done right, or at least as good as I can get it.

What the hell do you mean? and why would I need to ask, most people that download files would just post feedback, it is just common courtesy, but if your talking about the sync'ing of the files, I think I read it in his thread how he did it and Ady's comment just added to what I thought, it was not done right, they should have been PAL encoded and then converted to 6 mono wav files and edited in Vegas to the original audio, but whatever, thank you for the "Why not ask?!" that was cool.

Well the sync looks pretty good but i can't understand what is making the centre channel sound so hollow, especially if its DE's 5.1 rip from the laserdiscs (which i haven't heard). Stretching the audio wouldn't cause this problem, but it would cause the warbling.

I know what a problem syncing the laserdisc audio to the DV broadcasts, but this is a laserdisc rip so there shouldn't have been many syncing issues when using the NTSC laserdisc audio. I just wish the stretch method wasn't used because it has completely ruined for me what could have been a great preservation.

Adywan thanks for checking out my release. :) dark_jedi is correct I used DarthEditous' AC3 rips from the NTSC LaserDiscs that Jetrell Fo supplied me with.

I'm sorry to hear that there are problems with the audio! To be honest audio is not really my thing I am much more of a video guy, it also doesn't help that I don't have a 5.1 set-up. I hope to get some Dolby certified 5.1 headphones in the future but for now its just not in the budget. :(

If I remember correctly the method I used to get these to sync, which is not perfect, well in fact its probably terrible and is not the one I would use knowing what I do now, was:

1. Open each AC3 file in Apple Compressor and export as a 5.1 LPCM audio only quicktime .mov using Compressor's built in retime function to go from 23.976 to 25fps duration, from what I read online Compressor's retime function is suppose to correct/compensate for the pitch shift.

2. In Final Cut Pro I had already edited together my LaserDisc captures (video & audio) so I knew the stereo (Dolby Surround) audio was in sync to the video.

3. To get the audio to sync I added 6 extra audio tracks to the timeline of each film, and imported the 5.1 LPCM .mov files I had created earlier.

4. As dark_jedi mentioned they didn't sync properly so I turned on the audio waveforms so I could see what I was doing and then using the centre channel of the 5.1 and the stereo from the LaserDiscs I lined up the start of the audio and then moved along to the end and adjusted the playback speed of the 5.1 audio in Final Cut Pro as necessary to get the ends to line up, I then scrubbed through checking the waveforms to make sure they didn't go wildly out of sync between start and finish.

5. Once I had done one audio segment I just repeated the process for the others as there was 3 for each film. With the 5.1 audio sync'd I removed the LD stereo audio from the timeline leaving just the 6 5.1 tracks in the order L,R,C,LFE,Ls,Rs

6. With the audio sync'd I sent the timelines to Compressor and used that to export the M2V and Dolby 5.1 AC3 files to author the DVDs.

The reason I never did an NTSC version of the '97SE LaserDiscs was because no matter what I did when I exported the M2V and AC3 files for NTSC the audio and video would not match up. :(

Sorry to hear that Lee, but without good audio it ruins the experience as Ady has said, it certainly would for me, plus the fact that you did DL encodes to me(and this is only me) is a waste, it is only an LD, hell I didn't even use DL's for the 97 SE V2(DV Broadcast source) or the JSC V2 I did.

Adywan thanks for posting the comment about the audio sync its nice to know I did something right. ;) What did you think to the video quality considering the source was LaserDisc? Furthermore how does everyone else feel about authoring these as DL DVDs being too much?

I would be more then happy to have another bash at syncing the 5.1 audio and release an audio fix like what Adywan did for his theatrical TPM DVD if someone could point me in the direction of a good guide on how to sync the 5.1 audio properly. :)

Firstly, I don't understand this constant hot tempered nature of yours is in like every thread when someone questions something of yours - a comment/post/work you've done etc etc.

What I meant was you seemed very quick to say that you are gonna hold off, and let everyone know that in his thread. Seems a bit extreme and harsh, if you ask me. There may be a problem with the audio, but all you need to do is ask Lee about it, not be so quick to dismiss something and almost put others off downloading it as well... I know you wouldn't want someone saying "I am not downloading V3 because of..." with you only finding that info out now, and not even sure if it was true, then again you might.. I don't know.. but either way, I think it's unfair to people who may want to download it, and be put off by possible misinformation.

Let the author of the thread confirm the problem properly themselves is all I am saying. I understand feedback is essential, but I find that a bit hypocritical coming from someone that is very quick to shoot people down in their own threads about particular things.

I am not having a 'go' at you but it's not the first time I have seen you do it d_j; it's been in other threads too, that's why I am finally saying something now..

You are so right sitting on your high and...., well forget it, you said your piece and really I could care less what those fingers of yours type, I do not mean to come off harsh but hey if I do then I do, there are others here that come off as harsh to but I don't finger point because I do not care, this is the damn internet LOL, there are lots of keyboard courage people here, but back on topic for Lee we should go.

1 more thing, I hope you don't download the V3, again I could give 2 shits, sorry Lee.

It doesn't matter now; Lee has confirmed everything.

But anyway, I have nothing personal against you or anyone. I just can't understand you sometimes. You're posting sometimes rubs me and other people the wrong way. You say one thing, but mean something else. But this is the problem with the internet; not seeing what people actually meant behind their words, other than just seeing words. This is also why I don't really participate with anything internet wise much, other than this site for Star Wars.

It all depends on the encoder used for Mpeg2. Some encoders need the higher bitrate to maintain the quality while others, like procoder3, can do the same job at a lower bitrate. As these were a first gen rip from a laserdisc then i think the DL approach was the way to go. With the broadcasts being only single layer in the first place then DJ's approach of SL was the way to go with his as the extra bitrate wouldn't have affected the quality very much

For the audio , i can't help wiht that because i don't know what apps that i use would work on a Mac (i'm a PC guy), but you need to speed the NTSC audio up from 23.976fps to 25fps, not stretch. Eac3to does this easily and you can get a gui for it but i don't know if it would work on a mac. I'm sure that someone here who uses a Mac would know how to do it

I asked this same question a while ago when I first started all the audio sync'ing I did, I will try and find the thread, I am pretty sure it is in the how to's, but in a nutshell you need to encode to PAL, then split into 6 mono wavs, load your original audio into Vegas, then your 6 mono wavs, then I muted all the mono wavs but the center, zoom in on the timeline, and wallah, you can see everything you need, again in a nutshell.

*edit- I just read what Ady wrote, you are on a mac, I have no idea either.

I know what you mean about if the audio sucks it ruins the experience I have a few retail DVDs with crappy audio quality Casino Royale for instance and it really detracts from the pleasure of watching the film, like I say I don't have a 5.1 set-up so I wasn't aware of this issue until now, but now that I know about it I am very annoyed by it and want to put it right if I can!

Thanks for the feedback Adywan. If you have the time could you explain how and what you would use to do the speed up on a PC? Running PC apps on a mac is not as difficult as you might think, I have both Wine and a virtualised Win XP machine set-up so between them I should be able to use anything you do :) Also and I apologise if I am a bit slow up the uptake but could you explain the difference between speeding the audio up and stretching it?

@dark_jedi thanks for the offer of the audio guide, if you can still find it I would love to see it. :)

Many Thanks!

Lee,

Let me applaud you for staying straight and focused in this thread.  Everyone has a right to an opinion for sure but you haven't even flinched when you received criticism that read a bit tough and discouraging.

I have supported this project of yours from the get go and I'll happily keep supporting it as the 1997 S.E. does deserve a good archive, especially a DL LD one and I firmly believe that your work here could only benefit others who may try their own if they can get past all the minutia of software, scripts, coloring, and so forth.

Cheers my friend.....

:)

It's definitely better to let the pitch shift upwards along with the audio speedup for PAL, rather than using anything to keep it the same.  I really don't like the way this sounds, but unfortunately it's vastly preferable in sound quality, because short of having access to some real high grade professional equipment, nothing that keeps the pitch the same during speedup is going to sound any good.  (And maybe not even then.)  It's basically the equivalent of letting a tape reel spin faster during playback, instead of doing all kinds of complicated and destructive alteration.

I use a Mac, but I don't actually know of anything that will change the speed on the file directly.  What I would do is split the AC3 into its individual channels using either a52decX or Mpeg Streamclip, then open them in your audio editor and tell it to speed them up by the appropriate amount: 25fps / (24/1.001) = 1.0427083333333..., so just over 4.27% speedup.  Then you can edit the faster versions to synch as needed.

Thanks Hairy Hen! Audacity has a change speed effect here is the description of it:

"Change Speed - changes the speed of the audio by resampling. Making the speed higher will also increase the pitch, and vice versa. This will change the length of the selection."
From: http://audacity.sourceforge.net/onlinehelp-1.2/menu_effect.htm

Does this sound like it would do what I need it to do?

Many Thanks

Is there a PAL 5.1 equivalent audio rip instead of the NTSC audio?  Maybe at least someone here who'd consider capturing the audio from your LD's if you sent them out?  That would probably be a better way to address this, though it would add some time to it....could be far more worth it in the end instead of the audio you have now not getting the chance to shine properly.

Just some thoughts anyways.....

No; 5.1 audio could only be put on NTSC laserdiscs.

The PAL laserdiscs of the SE have 2.0 Dolby Surround audio.

Edit: @Lee, yes that's the option you want to use.

There is no PAL DD 5.1. As I understand it the reason why PAL never got DD 5.1 is this, because PAL has a higher vertical resolution than NTSC there was not enough available bandwidth on the PAL LDs to have 2 audio tracks, so PAL was limited to 1 audio track. When you're limited to 1 audio track you can't go and make it DD 5.1 as most people probably didn't have the RF demodulator needed to make it work, so to make sure everyone could play the LDs the best they could do for PAL was Dolby Surround aka Dolby Pro Logic.

I still have the Dolby Surround captures so If worst came to worst I could always just put out a fix using these instead of the 5.1.

EDIT: @ Moth3r, thanks for answering my question :)

hairy_hen's post about pitch correction vs. simple speedup made me wonder. I discovered that the 1995 UK VHS releases had pitch-corrected audio. The "coffret" laserdisc set has English audio; is this the same corrected audio track in digital form?

I can't remember whether the French audio on the individual LD releases had speed up or not. Never really paid much attention to the French track.

The GOUT Region 2 PAL discs have sped-up audio.
