Info: Fixing the ESB TR47 4 second black screen
Time
That sounds good. I'll have to get ahold of that program and try it out. In what manner can you load the DVD into it? Do you have to join the VOB's first? Also, did you check the audio at the edit point? When I made the edit in the joined VOB's the audio after the edit seemed slightly out of sync but I wasn't positive, because it was right on the verge of what is noticeable. The original unaltered TR47 is also right on the edge of what is acceptable for audio sync in parts and I had to watch and compare scenes over and over to finally decide that yes, the edited version was ever so slightly more out of sync than the original TR47. When I looked at the audio stream in GoldWave I could see that it was .058 seconds more out of sync than the original TR47 version to be precise (.058 second "flatline" right at the edit point); which wouldn't even normally be noticeable, except for the fact that the original ESB TR47 is already so close to being out of sync to begin with (but still in the acceptable range).

These will be the single layer discs simply based on the fact that NOT all of us have dual layer writers or dual layer media (we'll some of us do )

It isn't much of a problem to run it through DVD-Shrink or whatever transcoder you prefer if you don't have a DL burner or media; at least the full DL version would be available and people could decide when they get it what they want to do with it.

Torrents for little noobs like me?!?
Time
I got ROTJ TR47 from myspleen.com and though it said it was complete, it was missing the 5th and final VOB (VTS_01_5.VOB 367.82 MB). I guess there is no way to just try to download that single file so I am trying it again (ugh). Hopefully the same thing doesn't happen.

Also, I don't know much about torrents; how do you seed? And, what is the difference between seeding and simply downloading and by default, uploading to others at the same time?

Yeah, I have seen those and they are amazing. I compared the screenshot of Vader/Shaw on the X0 site with a shot of the same frame on the 2004 DVD and while the DVD image edged it out by a bit, it wasn't by much; plus the colors were better on the X0 shot than on the DVD. The improvement of the X0 compared to the TR47 was greater than the improvement of the DVD compared to the X0.

But I grew up watching vintage 80's rental pan & scan VHS tapes and TR47 is certainly an improvement over those. Plus, X0 is still a ways off, "pre-production" stage as Laserman put it in the X0 thread.

To all others reading this, keep in mind that you will have to be running NTFS in Windows 2000 or XP. Windows 95/98 can't hang with file sizes this large.

That's true and I'd forgotten all about that. I haven't run FAT32 in years. 2 GB is the limit for a single file in FAT32 I believe.

I didn't want any menus. If I'd gotten the Rowman set, I would have run it through DVD-Shrink to get rid of the menu's anyway.

I thought about doing it the way Rowman did with TMPGENc DVD Author (he did use TMPGENc DVD Author didn't he?) but MeBeJedi said in another thread that his version still left 1 black frame or something to that effect:
I thought there was a link to Rowman's technique, but it was still off by one black frame. I'm guessing that's the best it's going to get. - MeBeJedi

Time

Well, I finally fixed this DVD to my satisfaction and it can all be done with freeware or free-trial software. Here is how I did it in case anyone else wants to fix their own discs rather than trying to acquire Rowman’s fixed version.

Start by joining the 5 VOB files. I used “File Merger” (a tiny 84 KB general purpose freeware utility) to do this. I believe that it can also be done through the command line (CMD.exe). If you have DVD-lab you can drag and drop the first VOB into the assets box and it will offer to join the VOBs for you as well.

Then I used a program called “VideoReDo” (free trial, fully functional for the trial period with registration) which I found by clicking a link at the bottom of this forum. It has a big, non-resizable, fluffy GUI but it does its job well, i.e. deleting sections of video/audio on any frame in an MPG/VOB file and saving without having to reencode. Just select the first black frame in the 4 second black screen as the start point of the selection, and the first frame that shows Leia welding as the end point of the selection and then press your delete key on the keyboard. Anyone familiar with Vdub will have no trouble using this program.

I saved the file as an MPG and then used MPEG-VCR V3.14’s “GOP Fixer” on the file (steps 1 and 2). I don’t know if this was necessary or not but it did find and fix a lot of GOP time code errors which I suspect was a result of the cutting out of the black screen earlier.

Then you can open the file again in VideoReDo and save as elementary streams (WAV and MPV), or any other method you care to use to demux.

Open the WAV file in an audio editor. I used GoldWave which is shareware. The same thing can be done with Audacity (open source freeware) or if you have Nero Ultra, that comes with a pretty good wave editor as part of the suite. Move your start selection to about 50m 31s or so (press play and listen for the sound of Leia welding to get the exact point) and your end selection a second or two after that and zoom in. Keep zooming in until you can clearly see a .058 second long “flatline” at the “C3PO-to-Leia welding scene” transition. Delete that gap of silence that shouldn’t be there and then save your changes.

Load the MPV and the WAV into Muxman (free for the basic version) and load this chapter list:

003447
014946
027067
032677
040223
045343
056331
065127
074462
080757
093726
108663
118691
132823
139846
147538
157127
167898
178759
194683
206169
212609
216519

And select the save location and click start and that is all there is to it. The results are perfect and there is no quality loss because nothing gets re-encoded. The black is completely gone and because of the frame-accurate editing of VideoReDo, you don’t lose any frames that are supposed to be there. The chapter list is accurate relative to the unaltered TR47 DVD. It is 4 seconds off for the chapters that fall past the edit once you remove the black screen. This could be adjusted in the list itself if anyone wanted to*.

Hi all, Need help with editing VOB file
Time
OK, apparently I was making this more complicated than it needed to be. I approached it differently this time. I simply loaded the VOB that needed the black screen removed into VideoReDo and cut the black out of it, then saved it as "all files" using its original file name with a vob extension (VTS_01_2.VOB) then I put it back in with its other untouched VOB files and IFO's. That worked perfectly. It plays through fine, the black screen part is gone completely and it stays in perfect sync. All the chapters are still there, though chapters after the edit, take you to a spot 4 seconds earlier in the movie than they did before, which is to be expected. I am surprised it worked; I figured the IFO's would no longer match up with the running time of the movie and something screwy would happen. Just to be on the safe side, is there anything I should edit in the IFO's to make it match up? or maybe just create new ones altogether for those VOB's in IFOEdit?

Edit: As it turned out, this played fine in PowerDVD but it wouldn't open in any transcoders (always failed when it tried to open the edited VOB) so I kicked it to the curb.

Hi all, Need help with editing VOB file

I'm assuming the original VOB did not go out of sync at the same point? Is it out of sync for the rest of the film? That's correct. The process was like this:

1. DVD Lab to join the original VOBs from the TR47 DVD into one VOB named DVD Lab's default name when doing this, "join.VOB".

2. VideoReDo (hokey non-resizable GUI and I'd never heard of it but it did what it claimed it could do) to open "join.VOB" and accurately delete the 4 seconds of black screen and save results without re-encoding. It saved with the MPG extension so the file name is now "joined minus black screen.mpg". Playback of this file showed it to be exactly what I wanted. The cut edit was perfect and the audio was still in perfect sync throughout the entire movie.

3. DVD Lab to recreate the DVD from the 4.33 GB "joined minus black screen.mpg" file without re-encoding. I did try it without demuxing which was against DVD Lab's popup warnings and when I went to complile the DVD it sat there saying it was "checking streams" or something like that, for a couple of minutes and then it claimed it was "done". Well it obviously wasn't "done" because 2 minutes isn't even long enough to simply copy a 4.33 GB file from one location to another on my machine. When I checked the destination folder, all it had done was create empty VIDEO_TS and AUDIO T_TS folders along with a 0 byte VOB file in its temp directory. So, I loaded "joined minus black screen.mpg" again and let it do everything it was recommending, i.e. demux into elementary streams and also convert the LPCM audio to WAV. I added the chapters and compiled the DVD which consisted of muxing and setting navigation parameters. The finished DVD was in sync for the most part. In the first Lando and Han scene it went out of sync and then back in sync several minutes later. It may have gone in and out of sync more than just there but I didn't sit down and watch the whole thing; I simply scanned through it.
My only guess would be that there was an error in the audio file there, or an error in the extraction (did you try it more than once?). You might want to run the VOB through VOBrator, extract the audio as a WAV, and load the WAV into DVDLab Pro.
I only demuxed the "joined minus black screen.mpg" file once. I have never used VOBrator, but I could also demux to a WAV with VDubMod or I could run this original LPCM file through BeSweet to get a WAV. That will help pinpoint the problem I guess.
Don't knock DVDLab Pro for this. I, for one, love the compliance checking. Keep in mind that you can for DVDLab Pro to *not* demux the files. You might want to try this, or even have DVDLab join the VOBs for you.
I'm not knocking DVD Lab for that; in fact, its ability to create a DVD from DVD compliant files without re-encoding is why I used it in the first place. I am beginning to question the accuracy of its muxing/demuxing abilities however.

Well, I made a perfect edit, and I do mean perfect. Just for the hell of it I clicked on one of the links on the top of this page and downloaded a free trial of a program called "VideoReDo". It claimed to be able to cut out segments on any frame of MPEG-2/VOB files and save without re-encoding; in the same manner that Vdub can do with AVI's. So I joined all of the VOB's together and cut out the 4 seconds of black screen and saved as an MPG which only took a few minutes as it was just a direct stream copy. The result of the MPG was perfect.

I ran it through DVD Lab to turn it back into a DVD and readd all the chapters where they are supposed to be. I let DVD Lab demux the VOB and then when adding them to the movie title; DVD Lab didn't like the raw LPCM audio stream. It said that it had no header and wanted to convert it to a WAV. I allowed it to do that and made the DVD. It was great except for one thing. The audio got slightly out of sync during the scene where Han first sees Lando at the cloud city.

WTF? Do you think the conversion to WAV had anything to do with that or is DVD Lab simply a piss-poor muxer? Like I said, the MPG file that was saved from "VideoReDo" after I cropped out the 4 seconds of black screen is perfect and is a bit for bit copy minus the black screen. It matches up exactly with how that scene appears on the 2004 DVD; i.e. the close shot of C3PO and then the next frame with Leia welding; no black frames and no loss of frames that are supposed to be there; and perfect audio sync throughout.

Any other DVD authoring software I should try (one that can turn DVD compliant video and audio into a DVD [VOB's + IFO's] without re-encoding like DVD Lab can)?

Well, as I said, it's not terribly accurate. My overall solution is rather different from what you would do: I'm making my own version.

So you don't know of any way to do it other than re-encoding it? How did Rowman do it? Did he just get it "close enough" or right on the money? and did he re-encode or make a bit-for-bit copy minus the 4 seconds of black screen? When I made my initial post on this thread, I hadn't acquired the TR47 copy yet and I wasn't even sure how the actual scene was supposed to look exactly. I just figured "remove 4 seconds of black screen; DVD Shrink can do that" but the way it worked out with the key frame spacing; it didn't line up perfectly with the start and end frames of that black space.

Like I said, I did make an edited version that only has about a half-second of black screen there with no re-encoding involved (I decided that was better than losing a few picture frames from both sides of the 4 second gap), and it is far better than 4 seconds of black screen; but I don't like "good enough" unless it is my only [realistic] option.

Edit: Can key frames be added without re-encoding? If I could do that, then I could make the start and end frames of the 4 second black space, key frames, and then proceed as normal with DVD Shrink.

I tried the DVD-Shrink method and it wasn't accurate enough to satisfy me. The key frames in the TR47 MPEG-2 stream are 12 frames apart and this simply isn't good enough. Granted, you can make it a lot better but your options end up being either leaving 15 frames of black screen in there (less than a second's worth) or losing a few frames of the video before and after the black screen.

I could do it perfectly if I wanted to re-encode; which I don't. Can you explain how to do it without any re-encoding?

That's not true -- but it's also not what you mean. Of course it is possible to end up with more information than you started with. That's pretty much the whole idea. What I know you're saying is that it's impossible to end up with more useful or accurate information than you started with, and you do have a point there. No, it is not possible to end up with more information than you started with; and your qualifiers are not necessary ("useful or accurate information"). Increasing the quantity of redundant information is not the same as new information. For example, a single text file that says "hello" = the same amount of information as a million copies of the text file that says "hello". Any possible version you could make of a movie starting from the source is already a potential of the information that is already contained in the source. When you talk about adding things intelligently, then that is different, as you are adding more sources by default when you do that; for example, Lucas' additions in the SE and DVD versions. But simply encoding and filtering and whatnot does not add information. It is only working with what is there.
Now, let's say you wanted to make a better version of that sine wave, but you start from the blocky version. It doesn't take that much thought to see it's possible (and maybe even relatively easy) to draw a much smoother curve that fits the data. Same frequency, same amplitude -- better resolution. In fact, you could probably downsample and get the same exact original blocky curve back -- or you could downsample less and still get something smoother and more pleasing than the original. Clearly, in this case, you have ended up with a result that has more information than you started with, and that information is useful and accurate.
Are you saying that you can look at a blocky sine wave and manually draw a much smoother curve? That is using more than just one source. If you are using your own drawing skills and knowledge of since waves to draw it then you are adding yourself as a source. If you are running it through a program that can interpret the sine wave into numerical data and then draw out a nicer looking wave to represent the same data then you are adding the programming of the software as a source. That is a different breed of cat altogether than encoding and filtering. Maybe one day we will have software that can look at a fuzzy image of a tree and extrapolate that into a picture that appears identical to a high quality image of the same tree; but we aren't quite there yet. This would still be a case of adding sources, rather than gaining information from a simple encoding or filtering process.

About that, I did a quick test converting captured LD footage in DV format to XviD format, the only thing I did to the LD footage was undo the 3:2 pulldown, the XviD was encoded at 100% image quality with each frame being a keyframe, had I gone ahead and encoded a 2 hour capture the avi would be an estimated 9-10gb in size, so it's perfectly possible to have a 2 hour 4.3gb XviD avi by having 1/2 or 1/3 the number of keyframes.

With default settings in XviD at 100% quality, I have never gotten much over 2.5 GB for a movie. Increasing the number of keyframes would certainly bring that up but that always seemed to me as though it was defeating the purpose of MPEG-4. Either way, your idea sounds interesting now that I have read more of this thread than just the initial post that I replied to last night.

It is certainly possible to make an LD transfer look far better than the original LD, and you can improve the quality substantially on an upsample. I mean, if you're going to scale, you'd may as well do it at less than real time with competent filters, rather than let some budget TV try to do it on the fly.

I don't know what you're looking at to say otherwise.
It is impossible to end up with more information than you started with (i.e. your source). "Looks better" = subjective and is not synonymous with higher quality. For example, a 1400 MB MPEG-4 encoded from a 5 or 6 GB MPEG-2 DVD source often looks "smoother" than the original. It is not higher quality than the source however. The source contains all the information you need to make all sorts of different looking versions via processing. The resultant 1400 MPEG-4 does not because of loss. Even if you re-encode to the same bitrate, format and resolution there will be some loss (not much); it is inevitable.

On the other hand, now that I have read the original poster's reply to my post, I can see the potential benefits of upscaling the image in the initial encode rather than doing it on the fly via hardware stretching.

When you "buy" your movie, you are not authorized to distribute it - even to one person at a time.
Which is exactly what I just said here:

If I buy a movie, I can not then set up a site to stream it for free to people, even if I only allow one person to stream it at a time. I also can not have a public showing of the movie without specifically paying for that right.

I'm not sure why you are repeating after me...

Libraries, on the other hand, have limited authorization in distributing copyrighted work, so long as it is returned.
I know they do. I never claimed they were breaking the law. I said that the concept is the same as what bootleggers [illegally] do; and the authorization for them to do it is arbitrary which makes the application of the law, contradictory. Reread what I said here again:
Quote

So downloading a movie is technically illegal. So what? Contradictory application of the laws (the beloved libraries vs. bootleggers for example) makes them null and void as an ethical or moral issue as far as I am concerned.

See, a library does its bootlegging activities legally and I never questioned the legality. So if what bootleggers do is not moral or ethical, then what the libraries do is also not moral or ethical; and vice-versa; because the actions and results regarding what bootleggers do and what libraries do, are fundamentally the same.

If anyone has a moral issue with bootleggers, they have to have a moral issue with libraries as well, or else their reasoning is internally contradictory ("selective reasoning"). If anyone tries to justify the laws pertaining to bootleggers (rather than admit that they are simply arbitrary) then they also have to admit that the same arguments that attempt to justify the laws against bootlegging are equally valid against the activities of libraries.

If you support the laws against bootlegging for any other reason beyond "well, it's the law" and at the same time, think that libraries do no wrong, then you have contradicted yourself, by default.

Did you forget the part about the library "buying" the book? How many libraries do you know of that make thousands of copies of the book available for people to take home and keep?

There are quite a number of differences.

There are no differences in the concept. If I buy a movie, I can not then set up a site to stream it for free to people, even if I only allow one person to stream it at a time. I also can not have a public showing of the movie without specifically paying for that right. In both cases, the people who got to see the movie for free didn't [necessarily] end up owning a copy and in both cases the copy was originally paid for. It is no different than what a library does. BTW, libraries don't pay extra for their copies of books; in fact, they get a discount typically. They can also accept book or movie donations, which can then be read or viewed by as many who want to, for free.

About movie rental places and movie theaters as mentioned by someone else in the post, the rights to distribute or show publically in the manner that they do are paid for via license fees; though I don't know of all the details, never having been in the movie rental or theater business or anything.

What would be the point of that? You can already play the DVD on a DVD-ROM drive to watch on a projector. You certainly will not gain quality by going to a higher resolution than 720x480. You can never gain quality by going to a higher resolution than the source; in fact, you will never gain quality over the source (in this case, 528x480 laserdisc); period. The fact that LD is an analog video stream that will always suffer loss just getting to its destination; added to the encoding to MPEG-2 or MPEG-4; guarantees a loss here. Increasing the resolution over the source only magnifies this loss (much like zooming in on the source itself would make it look worse because there is not enough information there for a higher resolution than it is intended for). It is in the acceptable range to increase the resolution of LD material to DVD standards but that is already pushing it; to saying nothing about trying to go even bigger. It would be little different than playing the DVD in Media Player Classic and zooming it to a higher resolution on the fly.

One more thing; MPEG-4 would be saturated for a 2 hour movie at something under 3 GB; probably around 2.5 GB, so a 4.3 GB MPEG-4 file (XviD/DivX/WMV/MOV/ect) for Star Wars is not likely even if you tried nor would it be of any benefit if you succeeded.

When are they going to go after the biggest offenders of all; i.e. that "sacred", untouchable institution known as the "public library"? There really is no difference here in regard to the concept itself. A bootlegger uploads a movie or a song and a bunch of people can see or hear it for free. A library buys a book or a movie and the whole city can read or see it for free.

Hi all, Need help with editing VOB file
Time
I think DVD-Shrink only works on keyframes as well, but other than that, it's very easy to use, and free.

You're right. Fortunately key frames tend to be pretty close together on the MPEG-2 streams in VOB containers.

Any free MPEG splitter/joiner can join the new VOB to the old VOBs.

Do you have an example of a good one that is free? I know that DVD2one works perfectly for joining VOB's. Come to think of it, the small, free general purpose utility called "FileMerger" can join VOB's, but it doesn't write out a corresponding IFO file of course; it is useful for joining multiple VOB's to be directly edited in VDubMod before making an AVI. That's what I like about DVD2one; it doesn't simply join VOB's, it writes out a new set of VOB's along with writing out a corresponding IFO file (the new information in the IFO's is what is really responsible for joining the files, as the resultant VOB's are still split into 1 GB chunks) and it is a ready to go DVD when it is done.

With DVD-Shrink you can set the start and end points on any frame and nothing else is touched, i.e. no re-encoding. I would load the entire movie into DVD-Shrink and leave the start point at the beginning and set the end point at the beginning of this 4 second gap and then let Shrink make a DVD out of that. Then, load the entire full DVD in Shrink again and set the start point at the end of the 4 second gap and set the end point to the end of the movie. Then let Shrink make a DVD out of that. Now you will have two DVD's. Use DVD2one to seamlessly merge the two titles/DVD's back into one (it excels at doing that and again, no re-enecoding involved). The only problem is, DVD2one isn't technically freeware I don't think and I don't know if it has a trial version and if so; what the functionality of it would be.

Idea: original film - get a copy of the original film reels from the Library of Congress?
Time
There are plenty of theaters that specialize in showing classic movies. Shouldn't some of those have a copy of the original OT on film? Who supplies those type of theaters with their classic movies anyway? That might be an even better place to look. If you found a theater that had a copy, maybe they would be willing to rent it out? Maybe whoever supplies them with their movies rents or leases them to the theaters in the first place?

As far as the transfer goes; don't colleges and universities often have film departments that might have the resources to do such a thing, such as a telecine machine? If they have a broadcasting school then I would think they would need to have a telecine machine, since it is the only way to show film content over the air (NTSC broadcast). I'm just throwing random thoughts out here as I don't know much about it but it seems like it would be easier to get the cooperation of students at a college than it would be from an official transfer house; considering the legal issues involved. And, if copies of the original films could be rented or otherwise temporarily obtained it should be a lot cheaper than trying to buy them.
