Success.
-tempo -4.096
Syncs fine. The audio quality is surprisingly good for a freeware alternative.

I see it uses SoundTouch, which I already use with BeSweet/BeLight. I figure what I need is the '-rate' setting since it seems to preserve the pitch, I just can't find the right number.
It SHOULD in theory be "-tempo -4.2709376042709376042709376042709" but that ends up long. I stupidly tried 1-(23.976/25) = -4.096
The final length looks right and the pitch seems unchanged with pretty good quality (mind you it is a commentary track).
I'll see if it successfully syncs later.
Thanks. That is indeed the problem. At 104.27% SoundForge is more than 2 seconds off of the correct length.
Using a time calculator it seems I am only getting 104.245%. SoundForge isn't too good at math it would seem.
It does have the ability to let you enter a final length. Good because there's more flexibility, bad because there's now an extra step of using a time calculator.
Edit: Hmm. Even entering a time directly it misses the target. Wt?
Any suggestions for another software that does the same thing?
Hmm. Lots of views, but no comments.
Re-checked at 104.27%, the audio needs to run longer, not shorter. That means MORE than 104.27%. I can't think of any number that would correctly correspond to that change.
That's pretty much the one we've been referring to. For the most part he just swapped scenes as needed to incorporate the dog bursting.
(Also, I seem to recall some odd continuity problems with that edit.)
I commented in my PAL2NTSC guide about some cases where it is desirable when converting from PAL to NTSC to slow the video to 23.976 fps, but time expanding an audio track with pitch correction (instead of a straight slow-down).
Sony SoundForge has a nice Time Expansion tool. I calculated (wrongly it seems) that the expansion percentage should be 104.27% (which 25/23.976). Testing it the audio was out of sync towards the end.
Should that be an even 104% or more like 25/24 (104.17%) instead? Has anyone any experience with this?
Bingowings is correct. When the Quadrilogy DVD set was being assemble Fincher flat out refused to do a Director's cut. Even Ridley Scott did a Special Edition cut for the set but set the original version was the Director's cut and superior.
Fincher just never got over how they treated him while he was making the film.
As far as an uberedit goes, I did work on one for awhile. What I discovered is that the differences between the 2 versions is just to great. As soon as you start adding content from one into the other you create discontinuities in the plot. Swapping the dog burster for the yak is about the only change you can safely make between them. (And IIRC that causes a few problems as well.)
I don't believe there was anything in the workprint that was useful that didn't make it into the SE.
The Special Edition cut is probably the closest you'll get to a completely complete version. I know it completely changed my opinion of the 3rd film (I almost didn't buy the set because I had no interest in ever watching Alien3 again).
Don't let me dissuade you if you have a plan though. If you make it, I'm sure I won't be the only one who'll give it a watch.
Which reminds me, I really do have to work on my shelved Alien 4 edit.
Something else that will probably need to be added to this guide. Sometimes audio dubs (for non-English films) and commentary tracks are recorded while watching the film with speed-up.
As a result the film should be slowed, but the audio time stretched without slowing it
Example 1:
PAL movie: Track 1 = Movie soundtrack with speedup. Track 2 = audio commentary w/o speedup.
Track one should be slowed as described in the full guide. Track 2 can be slowed but it will probably sound funny. Instead, time expansion with pitch correction is needed (details below).
Example 2:
Japanese anime film: Track 1 = Original Japanese language track with speedup. Track 2 = PAL country's English dub. (Ghost in the Shell 2: Innocence UK release is like this).
Track 1 should be slowed, track 2 should be time expanded.
If you aren't particularly worried about the Japanese soundtrack being perfect (or you're going to strip non-English tracks) you can also encode the video as 25p and add 29.97 pulldown flags leaving the new dub track untouched.
For now, here is how to time expand:
(Edited to replace SoundForge with BeLight)
While decoding from AC3 to WAV in BeLight, click on the "Advanced Settings".
Before we used the 'Convert Frame Rate' SoundTouch settings. Make sure it is UNchecked.
Check the box that says "Tempo" and enter: -4.096
Click Ok.
Your command line in theory should look like:
BeSweet.exe -core( -input CommentaryPAL.wav -output CommentaryNTSC.wav -2ch -logfile Commentary.log ) -azid( -c none ) -soundtouch( -tempo -4.096 )
Also, if I might add, this version nukes the Starz logo, does it not?
OMG, this has been damn elusive. Cheers.
Edit: Previewed some of this. I am blown away. Much better than I would have anticipated for something so oddly cobbled together.
The only thing that's a real shame is that portions not on the CD aren't filled in from the movie. It would have been nice to see the unsung dialog cut in to preserve the story.
This is more music video... not that there's anything wrong with that.
Edit2: Hmm. Recode the video back to mpeg, resync to PCM audio (rather than cbr mp3), edit back in missing scenes...
I liked Connery with the birds as well. Willie screaming... pretty dumb, I wouldn't say dumbest.
Mind you, I thought falling in the raft was perhaps the least believable scene in the whole franchise.
AngryVideoGameNerd did a video for Spike TV "The Top 10 Dumbest Indiana Jones Moments".
Really it's almost a love letter to the movies. After watching it I've decided to lighten up on Crystal Skull... a bit.
Definitely worth your time: http://www.spike.com/video/cinemassacre-top-10/3197473
Just to bump this thread... was anyone able to grab this? It's like 45 minutes, not a major project.
Your awesomeness would be venerated.
I think Lucas has done the bumbling retard enough, In Last Crusade Marcus Brody, in phantom menace jar jar binks and in crystal skull Ox.
For a minute I thought you were referring to George Lucas as being a bumbling retard as evidenced by his recent Star Wars and Indy films. But I suppose that works too.
The Misiniformation guide was crazy. I'm sure I didn't get half the referrences, but well worth the watch.
Shh. It's sleeping.
Is Farmergeddon OCPMovie?
His Flight of the Darned is one of the most brilliant things I've ever seen: http://www.youtube.com/watch?v=Lmh8xeX6SG0
Wandering the net I found information that suggested someone reconstructed Fantasia's Pastoral scene using footage from an episode of Walt Disney's Wonderful World of Color combined with the DVD video and audio.
The best I can find is some streaming clips of it. Has anyone come across this?
I have a VCD of the original TV broadcast that's been floating around.
Video quality is mediocre, but the show itself is better than you'd think.
I would love to see a better version of this.
Applying Dolby Prologic IIx made all speakers except the center go dead on the English 2.0 track. Looks like 2-channel mono.
Would doing something like using English mono minus the L & R channels of the Russian 5.0 track make a good center channel (assuming they sync properly) or would that still not be quite right?
Edit: OK. Never mind. Testing the Russian track further: L minus R and R minus L completely neutralizes the channels. Definitely not any sort of true surround. I assume the surrounds have some sort of delay applied.
Not worth the effort.
I've never seen that error before. Mind you, it looks like you are using true VirtualDub instead of VirtualDubMod... which I would recommend.
Hmm. That IS a good point. It does seem stronger, but I'll have to compare a DPL decoding of the 2.0 versus the 5.0. Mind you that's also assuming it's 2.0 stereo and not 2 channel mono (something else I forgot to check).
Anyway, that's a good idea about extracting the center from a DPL matrix. (If I can figure out how to do that again.)
I've got a line on an older film that I've been looking for for a while: "High Road To China" (http://www.imdb.com/title/tt0085678/) starring Tom Selleck.
Unfortunately the primary audio track is Russian (?) 5.0. The English track is only 2.0.
As far as I can tell the non-English track is only an overdub in the center channel leaving the L/R/SR/SL clean and untouched (including English dialog that can be heard ambiently).
Am I crazy to think that I can take the 2.0 track, mix the channels together 50/50 and use it as a replacement center channel to create a new 5.0 mix in English?
For the life of me I can't figure why it wouldn't work. Using something like Sony's SoundForge to mix the L/R of the 2.0 mix, decode and extract the 4 useful channels to wave and then re-encode the whole thing back to DD.
Thoughts? Interest? Advice?
EyeShotFirst said:I haven't registered and the forums won't let anybody who doesn't have an account register. So anything going on at fan edit forums I am clueless to.
Same here. Anyone who wants to share info from that site over here would have my thanks.
I'm told that there will be no HD version of this.
Unless somone capable of raw caps wants to take this on, I'll use my DVR-DVDr combo unit to record at very high bitrate and then deinterlace/recode.
So sad. Why can't they just release everything on DVD and let us decide what we want instead of 10 Underworld releases, and 30 Fifth Element versions. Sure they're good movies, but they're not THAT good.
Edit: For anyone curious about this, I found the trailer online: http://www.videodetective.com/TitleDetails.aspx?publishedid=00002071
