I'm probably gonna get clobbered for being negative, but I assure you, through this constructive criticism, I'm only trying to make a good thing that tiny bit better:

The Star Wars logo used looks pretty budget. There are definitely better versions out there. This one looks to have 'A's that are too narrow and 'R's that have too big an included area at the top. A little attention to the logo, and this bizzle will be off the hizzle.

Oh, I think you'd get hammered pretty quickly on that one. I think if it's on any permanent media, rather than generated via some set of instructions, you're busted.

However, I don't think a huge AviSynth script that started with the DVD as its source would either be illegal or violate any patents. So you could do all the colour correction, re-editing, etc., you liked, put it in an AviSynth script, and sell that. I'll bet you could even sell the mattes and other differences between the frame you want and the frame you've got, since you'd be creating those works yourself. I would guess that you can't copyright the differences between one copyrighted work and another, just by owning the copyrights on the two works at either end.

Got the LD rips - Now How Do I Make Them Work?

I'm sorry. I really am -- I did already say "I apologize" in my last post, after all.

I also took steps to mend fences by pointing out where you could go to find a lot more info on all this digital video stuff. People here are helpful and somewhat knowledgable, but they're also here for a highly-specific reason (Star Wars OT Preservation), and thus you're far less likely to get the depth of expertise with the questions you're asking here as opposed to someplace where the focus is solely digital video issues, without any specific content in mind.

You'll also probably find that members here are predominantly interested in content in the DVD format, so that it can be easily played on standalone units, rather than MPEG4, which for the most part is still tied to computer-based players, etc.

If you spend just a little time getting to know how DVDs are structured and burned, you're going to get a lot more out of this forum -- even if DVD is, for you, just a necessary evil on the road to making MPEG4 stuff for yourself. All you need to know about DVD structure is probably found in this document: http://www.doom9.org/dvd_basics.htm. After that, then I'd recommend http://www.doom9.org/guides.htm. And after that, there's always Doom9's forums...

Remember that.


I did. If you'd stopped at, "I have no idea what to do with these *.bup, *.nfo, and other confusing files," that would be admitting you do not know, and I could live with that. But you continued with what I thought was the arrogant and condescending, "Why can't these LD rippers just use normal MPEG4/avi files that I can view with DivX Player?" as if LD rippers were somehow stupid for not putting things in a format you could understand. That's the part I took offense to. I probably shouldn't have, and I apologize -- it was early, and I didn't take into consideration the sorts of things I think and type when I'm frustrated, too. I still think an engineer should be able to do better on the self-education front, though. In admitting you don't know, you only really have to admit it to yourself. It's disappointing to me to see people with a similar sort of education as I've got being ignorant -- I don't think it makes the profession look that great (and this is a profession that doesn't look that great at the best of times). Sort of like a lawyer getting all confused and frustrated by the fine print on a sweepstakes entry or something. If expecting more from fellow professionals makes me an arrogant SOB asshole, well, I guess I'm guilty as charged.

You'll note that my post, however assholish, did answer most of your first questions.

BTW, unfortunately you can't just run out and buy these things. George Lucas has ruled that out. So downloading is pretty much your only hope. Or, if you are interested in the simplest possible way to get the material and play it at home, contact Rikter Blaksvn (you can PM him here, or visit his website) and for a few bucks, he'll hook you up with DVDs you can pop right in your standalone. I'll admit a nice monolithic XviD is certainly more straightforward to deal with than the arcane filenames of DVD. But DVD is so much more universal and flexible on anything but a computer, that it's definitely worth the time figuring out the structure and how to burn it.

If you're really interested in figuring all this stuff out (including how to deal with OGM/XviD/DivX/MPEG4/DVD/DV, and transcoding between them, etc.), I'd recommend heading over to Doom9.org. That's where the people who actually create the tools to do what you want hang out. And there are easy-to-follow guides galore over there, too. Highly recommended.

You're an electrical engineer and you can't figure this out? Wow. I'm a mechanical engineer, and even I had no problems noticing that the *.bup ('backup') files are part of the DVD file structure, and that *.nfo sounds enough like 'info' to try opening those files with a text editor.

If you Google a few things, poke around the data structure of known sources of video (e.g. a pressed DVD?), and post a few non-whiny questions, you'd probably find that the way things are done on most of the LD rips is more robust than 'normal' MPEG4 files (e.g. standard file type, menus, audio, etc.), and considerably easier to deal with than a good portion of the *.avi posts you'll come across.

I still can't believe you'd expose your ignorance so clearly, and then proudly qualify yourself as an engineer. At university, you're really supposed to be learning how to figure things out, not just mastering Ohm's law. For shame!

OK, it looks like Peter Pan is one of those big legal messes. Check out http://en.wikipedia.org/wiki/Peter_Pan_and_Wendy, near the bottom under 'Copyright status.' Very interesting.

The rights were assigned by Barrie (before his death) to Great Ormond Street Hospital.

In Canada and Australia, 'Peter Pan' is in the public domain.

If you want more of Lessig, and for free, check out his book "Free Culture," available in many forms -- for free -- on the Web. Or get it from your local library. Very interesting stuff. For example, did you know that NOTHING has entered the public domain in the US since 1923?? That's right: NOT ONE WORK has gone the way of the brothers Grimm, or Peter Pan, or The Jungle Book and been made freely available to all for publication or modification. Mostly thanks to the company that pillaged the public domain (see aforementioned brothers Grimm, Peter Pan, and The Jungle Book) for its ideas...

Under the US DMCA, isn't it illegal to rip a DVD movie for ANY purpose? Pretty sure I'm right. In other words, starting from the official Ep I DVD and making the Phantom Edit -- even for your own purposes at home -- is illegal. That's how stupid and draconian the DMCA is. MBJ makes backups of Disney DVDs so his original doesn't get messed up through repeated viewings and handlings? PIRATE!!! YOU'RE KILLING THE MOVIE INDUSTRY!!!

Clearly, he's really not. But why doesn't Jack Valenti recognize that??

Off-Topic: de-interlacing video

No, Moth3r, I know you know what you're doing. I was about 99.something% sure you'd IVTC'ed rather than deinterlaced. I'm quite sure MBJ is also talking about not IVTC'ing, rather than not deinterlacing.

Just to make things abundantly clear:

Inverse Telecine (IVTC) is used to reverse the film-to-video procedure (called, uhh, telecining). For NTSC telecine, the 24fps film frames (e.g. A B C D x6) are converted to 29.97fps video frames (e.g. AA BB BC CD DD x6) using 3:2 (or 2:3) pulldown. You'll note that because both video fields come from the same film frame, AA, BB, and DD look 'perfect', while BC and CD will show combing because they combine fields from two different film frames. This 3:2 cadence is quite predictable, so it's possible to drop a B and D field to get AA BB CC DD, and from that a nice progressive A B C D -- the same thing that was input. PAL telecine does 2:2 pulldown, so it's much easier to make progressive -- there are no annoying hybrid frames to deal with.

Deinterlacing is used to make field-based material (e.g. just about anything shot with a video camera, or produced for TV) progressive. Video cameras record separate, unique fields at twice the nominal frame rate (i.e. 59.94fps for NTSC and 50fps for PAL), so displaying both fields of a given video frame at the same time will show distracting combing effects. Unlike IVTC, it is impossible to reverse one procedure to recover the original whole frame, because it never really existed in the first place. The two fields come from two different instances in time. The best you can do is to have your computer do a bunch of math and try to smooth out the combing -- sort of picking an intermediate time between the two fields, say. This necessarily destroys some of the original information, but usually the tradeoff is worth it. That is, the end result looks smoother and easier to watch on a progressive display or display format than would the original video.

Decombing is deinterlacing. However, in AviSynth, Donald Graft's (aka Neuron2) DeComb is probably the best package that does IVTC. This is because DeComb is highly adaptive, and can do both deinterlacing and IVTC. Telecide() and Decimate() together, with appropriate parameters, can correctly IVTC film material and deinterlace field-based material even when they appear in the same clip. Doesn't happen that often with movies on LD, but it can happen a lot on TV shows, or anime.

So, to sum up, for LD OT conversions, IVTC is what you want. Stay away from deinterlacing!

Actually, you should never, ever deinterlace film-based material! That will screw it up royally, by blending fields that belong to different frames. Deinterlacing is irreversible: mess it up, and you'll never be able to get the full source picture back. Even some so-called "professional" transfers have been messed up in this way -- just check with anyone who deals with anime encodes (e.g. half the people on Doom9).

What you want to do with video that originated from film is perform IVTC -- inverse telecine. IVTC puts the fields back where they belong, and gets rid of those bastardized BC and CD frames completely. The result is nice, clean footage with all the original frames.

Now, for a source like DV from a camcorder, there is no choice but to deinterlace. Or, rather, to either deinterlace or not. IVTC is not an option, because the footage will have been shot at either 50 or 59.94 fields per second (i.e. 25 or 29.97 interlaced frames per second).

There might be an expert here, but that's sort of like trying to find something healthy at McDonald's. It can be done, but you're really looking in the wrong place. The place to look for AviSynth help is the dedicated AviSynth help sub-forum over on Doom9, at www.doom9.org. That's where the guy who wrote LimitedSharpen hangs out, so it's the best place to look for help.

Subtle or not, my dad's humour has been able to elicit that particular response on at least two occasions.

I'm just waiting for somebody, somewhere to come up with "hi's". As in, "Is this your's?" "No, its hi's."

Back to the topic at hand:

Tellan, if you have no luck otherwise, you can probably hit Rikter up for a copy of either the Isomix or EditDroid trilogy. For the cost of media & postage, he'll mail them to you.
