Would it not be better to upload it to usenet where everybody has access to it rather than myspleen where only very few will and for a very limited amount of time until people inevitably stop seeding?

I do not understand everybody's obsession here with myspleen and torrents that have to be constantly seeded, especially with bigger bd-25/bd-50 releases. Usenet is the way to go hands down for larger releases IMHO, they stay up for years without people having to waste their upload bandwidth seeding old stuff rather than being able to upload new stuff.

Can somebody explain to me what's so great about myspleen over usenet that offers so many advantages over it, apart from having a pay a little bit for usenet access?

 Well, I for one, don't have usenet or access to usenet.

Not everyone has access to it, but most have access to Myspleen.

Torrents are the most common way to transfer files quickly.

Torrents are great for fairly small files, 1-2gb maximum, 4-8gb file are fine sometimes if that file is pretty recent and/or popular but usually the seeds disappear pretty quickly on those, leaving download times of weeks or even months. From my personal experience, anything above 4gb become very slow to download very quickly after they've been released as the seeds drop off. Good luck downloading anything larger than 8gb if you're not there when the file is first uploaded and everybody rushes on to download it.

With usenet you get fast speeds and the files are there for everyone for 5 years or more, for files above 2gb, usenet is much better than any torrent and its a resource for everyone, not just those on myspleen. Usenet is so easy to use and cheap as well if you sign up for 3 day stints like I do on usenetserver.com whenever I find something I want, so there is no competition between the two IMHO.

Usenet is pref for me but I would take a spleen link over the nothing I have, so I am happy and grateful to the guys here

Okay, so a very generous member sent me a remuxed mkv of the DCP.

The file is 34 GB, so I have decided to wait for the LD audio that should be ready soon, mux it in and either create a new BD with tsmuxer or upload it as the remuxed mkv it is.

Which is more preferred?

I'm not familiar with the HD formats. Am I right if assume that an .mkv container can only have one audio track, while a Blu-ray can have many, so you can put in the "original" audio and the LD audio in there too? I'd say go with the Blu-ray then, as if anything is wrong with the LD audio (not in sync or something else) I can still switch to the 5.1 mix.

Actually, an MKV container can contain as many audio tracks as you'd like, so that's not a consideration.

The LD audio is being synched, so that shouldn't be problematic either.

LD audio please with the BD audio also 

PDB was so kind to send me the unsynced (bitperfect) Laserdisc audio. I converted the sampling frequency to 48 Khz with iZotope RX3 and cut the file with Audacity. It is in sync with the DCP Blu-ray now. I will upload it later today.

Btw, if anyone wants to sync any other audio tracks from the official Blu-ray release, just add a delay of -2343 ms to the audio track in tsMuxer. It will be in sync with the DCP version then.

Hey deho, is this going to Myspleen? Am I allowed to ask that?

Well, I'm not done syncing the audio yet. I thought I was...

The file is out of sync by almost 1 sec at the end of the movie. I now have to figure out the reason for that.

If it's done I'm planning to upload it to a file hosts. I guess someone can then up it to Myspleen as well...

That seems to be the issue. I will work on it later today and upload the audio once it's perfectly in sync.

You know that you have to find all the missing frames for perfect sync? I mean every single one of them. And cut & paste editing for filling up the holes. No time stretching.

One frame difference is noticeable for a very trained eye, 3-4 frames difference is noticeable for everyone.

Well, a lot of editing needed to be done. I had both, the original and the Laserdisc audio, open in Audition and they weren't in sync every 2-3 mins, sometimes even after a couple of seconds. The files are still not 100% in sync now, but I had it zoomed in to the max and these differences were just a couple of ms... After a while I said to myself: F... it! Not only because A LOT of editing had to be done for a 100% perfect sync, but also because I came to the conclusion that it wouldn't be visible. Maybe I'm wrong...

I tested it (didn't watch the whole movie again though) and to me it seems ok. I can't speak for the whole movie, but the scenes I saw were ok to my eyes and ears. I made 44 cuts (even time stretching once, but it was just a couple of ms. I didn't hear a difference), so it wasn't like I just left it alone most of the time.

I converted it to flac and dtshd and uploaded it to a file host. Everyone is invited to PM me for links. :)

If there are some flaws, please let me know. As I said: I didn't watch the whole movie again yet. I'm also far from an expert in audio editing...

Okay guys, with deho's sync ready, I will start seeding on Wednesday morning.

I will just have to demux the FLAC to WAV PCM to make sure everyone can play this without a hitch, and then make sure it syncs well.

:)

I don't know if there will be an audible difference between a good analog capture and a digital bit-perfect capture of the same track... I'd prefer the latter though, just to be on the safe side. :D

If it goes out of sync all the time, there is an error. The two (three) sources are may be in different formats (different speed), or one version has many framecuts, perhaps to get rid of damaged frames at scene changes. The third option is that there's a fluctuation in one of the recordings. But there is something for sure.

The best case is the fluctuation, but only if the phenomenon is indeed insignificant. If it goes out of sync by 10 milisecs every 2-3 minutes AND it goes back to sync BY ITSELF in the next 2-3 minutes, it should be fine. But from your description it doesn't seem that simple.

The time stretching method really has to be the last resort. Ever since I realized how wrong it is, I've never used it anymore, for any movie to fill up holes in the audio.

I don't think the speed is the issue here. My guess is framecuts. I didn't really invest much time yet, but I will have more time next weekend, if there is still something wrong. I'm normally a perfectionist, but my time was limited and it also was the first time I did this (syncing LD audio to Blu-ray video).

About time stretching: Can you elaborate on the downsides to that? Especially when its just used filling a 20 ms gap.

I was also thinking about the analog capture ilovewaterslides made. I have absolutely no experiences with Laserdiscs. If a Laserdisc features an analog and digital audio track, are they always from the same master? Could it be that the analog track is superior to the digital one, because less compression was applied (similar to vinyl captures that offer a higher dynamic range than Audio-CDs)?

|Got it on the way, THANKS to all involved :)

Got the full file, thanks to everyone who made it work I will make sure and seed it when my isp lets me 

Thank you from me too. Really appreciated.

By the way, the quality is absolutely excellent, and makes you wonder why anyone would mess with something so sharp and of such high quality. Grain is really moderate and non-intrusive.

One little things I noticed, though, is that pans tend to be jerky (especially during the clocks scene at the beginning). It it just my pc?

Thanks again :)
