HALLOWEEN - Fixing the audio and re-creating 1999 color timing (Released) — Page 7

Yeah kind of, just seems odd i don't see these problems. I'm not burning mine to disc just straight from a drive.

Oh and another thing, i mux mine into a m2ts file. Although i'm sure even if i did an mkv it would work just as good.

So you guys with sync problems, what player are you using to watch this? watching on my computer i use Splash player or media player classic. In my room or theater it's openelec xbmc.

Thanks for the feed back though on the audio guys.

I'm testing with VLC. Have not had a chance to test on my hardware media player yet.

It seems Turisu and I who are having problems are both using mkvtoolnix. I may try with tsmuxer tonight.

Also I should have the '99 THX DVD sitting on my desk at work, so will have a go at ripping that and testing.

Just wondering if you have also compared it to the 7.1 and fake mono mix tracks on the 35th BD? Because if I didn't perform the same tests with the other tracks I probably would not notice a delay.

Yep, i switched from 7.1 to the PCM still didn't see it.

Never tried VLC, not a fan of that player at all.

VLC doesn't have a nice interface but tends to play everything without having to install external codecs.

I don't think VLC is the problem actually, since the other tracks work fine.  More likely to be the muxing process or conversion to a WAV file.

Try converting the file to FLAC and see if VLC still has sync issues.  I've noticed that VLC can be a little finicky with WAV files at times.

I love it when things like this end happily.  Thanks DB and BnD, for helping folks get it done.

Well I can confirm my sync issue has nothing to do with VLC. To figure out what's going on at my end once and for all I demuxed all the audio files and compared the waveforms from the LD track and the BD 'fake' mono track side-by-side.

The two tracks are in perfect sync up until 00:20:12 at which point the two tracks desync and the LD track is ahead by about 120ms. The weird thing is that this is right in the middle of a scene so I'm not sure what would account for that.

Anyway the solution for me was simply adding 120ms of empty background sound at this point and now everything is perfectly in sync throughout the whole movie. :)

That's really interesting. Still doesnt explain how others are not having sync issues. Is it worth comparing the fake mono track to DB's w64 file?

looking at the original files provided by dark_jedi, the timeindex turiso mentioned is around the side change from disc1 side a to side b.

doombot, can you take a look at your project file for said timeindex? maybe you accidentally moved the files and got them out of sync.

i can't check this myself, as i still not have the bd at hand.

Ok so i did in fact find 120ms off but if you try to correct it then you find another part that's off. So it's no win situation, these 2 sounds tracks are not the same and can't be matched up 100%. It really now comes down to just how sensitive you are to lip sync.

Some one else will just have to take a stab at it but unless you do some fancy audio editing it's never going to be right on with the Criterion audio.

Turisu said:

Where else did you find it to be out of sync after correcting the 120ms at 20:12?

As far as I can tell by looking at the waveforms, the corrected audio remains in sync with the fake mono track from the BD right up to the end. Of course there are occasional spots where a sound effect or some dialogue is just a few milliseconds out one way or the other between tracks, but that's expected with two completely different audio mixes.

Well that's the funny thing, i didn't find the 120ms at 20:12 it was about 19ms off there. I was actually jumping around looking at side 2 for other spots,  115ms at 33:31. 120ms at 1:06:49 side 3. So i'm still not sure why you see 120ms at one spot and i see something different at the same.

Guess i should have mentioned this when i said i found 120ms

Also just found 131ms at 1:12:27 

I would say if any thing really kind of bothered me it would be side 4 which starts at 1:13:33 and it's very noticeable at 1:19 when Laurie is banging on the door screaming to get in.

I fixed this part and made a new wav file. The reason it was like this was if i didn't have side 3 and for together correctly then there was a slight audio drop out. So instead i moved side 4 just enough but had a small drop out between 3 and 4.I  fixed this by mixing audio from the end of side 3 into the drop out, now you can't tell there was ever a drop out and side 4 lines up much better now.

So is that 1:13:33 right to the end? Because when Loomis shoots Michael followed by the empty gun click is quite noticeable for me.

Also I wonder if its a bad idea to compare with the fake mono track on the new BD. Reason is that there is a theory it is a downmix of the 7.1 (or an earlier 5.1) where the centre channel is missing. Does that mean some sound effects will sound different?

The 1:13:33 starts side 4 of the laserdisc which is the rest of the movie of course. So from 1:13:33 and on, it's now shifted to the end of the movie in the new wave file i made, it's uploading now.

If i had a different mono file to compare instead of the so called fake mono i would. Though if the audio matches up on the fake with the new video as it should then there's really no need to.

Maybe there were issues during capture?

LMFAO! yea that has to be it, you obviously know nothing when it comes to putting LD audio in sync with BD's and DVD's lol, anyone here who has done this before knows very well that you cannot just sync the start and end and hope all falls in place in the middle, Jonno, Matt Stevens, Ady, and several others that know how to do this know very well you will have drifting, more then likely because of frames, you have to line up the start and physically go through the entire time line through each and every side to get it absolutely right, maybe some of the others will chime in so you will actually believe it lol, I have done a ton of audio files for our releases and for a ton of personal stuff, so why don't you keep your little attempts at personally bashing to yourself? funny it gets brought up very nicely here to drop things so we can have a civil discussion and then you throw that comment out there lol, good form dude, good form.

I think a few of us in this thread have learned some very important things about our fellow members.

DoomBot and I had pretty good discussions by PM they just went to shit in this thread for whatever reason, but I do thank him for attempting this and I really do appreciate it because as I said I am just so damn busy with Team Blu Projects and would not be able to get this done soon for all to have, that said I was pretty surprised at how fast it was done, these take some time, and it is very tedious.

A fully in sync file is coming soon.
