When something is sped up, you reduce the playing time of something and raise the pitch, because when you shorten the play time of an audio recording, the vibrations that make up sound are compressed together, so there are more vibrations per second, thus the pitch is raised. You can fix this in a sped up recording by pitchshifting, which is where you take the faster recording and artificially reduce the number of vibrations, thus bringing the tone down, while maintaining the faster speed.

So when American movies are converted to PAL, they run the films at a faster rate (roughly 4%) in order to bring the framerate up to 25 fps, and so they have to speed up the audio in order to bring it keep it in sync with the movie. Sometimes they just speed it up, making the voices sound slightly higher pitched than normal, and sometimes they adjust the pitch, bring it back down to the pitch of the original audio.

So:

sped up = faster & higher
toneshifting = time remains the same, pitch changes

Garrett, did you scan the text with the scanner software explicitly set up for scanning documents? If it's set to scan color or black and white (grayscale) photographs, the scanner will pick up a lot of shadowing and whatnot, and really pisses off the OCR software, because it'll think various shadows and whatnot are some sort of text or images. If it's set up correctly, all your scanned images should be duotone--no shades of gray. It makes it a hell of a lot easier for OCR software to do its thing. If the text is relatively clear, there shouldn't be that many typos popping up when the images are run through the OCR software.

So that goes without saying, but it will still look great. The point is to capture the Cinemax HD broadcast of the Star Wars movies in the full quality that they are broadcast at (whatever that is), and then back it up onto Blu-Ray BD-R disks (the best available HD optical disk format). If the Star Wars movies are broadcast on Cinemax at a very high video bit-rate and the movies go over 25 gig in size each, then dual-layer blank BD-R disks will be needed to back them up. But once it's done, the movies will be very safe on those disks.

As far as disk rot and such, naturally one would be expected to make extra backup copies of the disks periodically so that a flawless backup copy is always available, and that those disks would be kept in safe places and handled carefully. And once these disks get into the hands of sizable numbers of Star Wars fans, replacements could be gotten readily, if needed.


Uh... you guys are far too optimistic.

As noted below, HD movies on cable are of a lower bitrate than movies available on bluray and HD-DVD. Most 1080i transport streams utilize MPEG2 compression, and the average two hour movie is about 8 to 12 gigs (12 is considered good). However, they're starting to use H.264 compression on transport streams, but these tend to be lower in bitrate, as a tradeoff for their more effective compression. They're usually 8 gigs in size.

Looking around, the largest H.264 TS file I've found for a movie of roughly the same length as Star Wars IV is a copy of Spiderman 2 that is 17.1 gigs in size. The largest MPEG2 TS that I can find is a copy of Starship Troopers that is 16.9 gigs.

Oh, and for your amusement, here are some links to caps of Star Wars IV in 1080i, from an German HD broadcast a week or two ago. (H.264 TS, roughly 10 gigs in size):

What was with all the advance info about it being widescreen then? And I still don't know how The Weinstein Company has any rights to the film; they didn't actually get the rights to their films under Miramax when they broke off...


The "advance info" was pure speculation and optimism, plain and simple. Personally, I'm not surprised at all.

I just got around to watching the sample. It was GREAT. Like OCP said, edit the narration down a bit and bring in more of the actual sound of the movie into it (should be louder), but damn, very nice.

Only other thing was the picture seemed noisy (due to quick and dirty compression?), and the picture should be a little darker. But for a proof of concept, that was great. I'm not a Star Wars fan, but I really like what you did. I would watch more than one of these. Think you could find enough material in the first two movies to come up with one more decent film? Amidala's ship does look pretty damn retro.

A thought I had about the Jabba scene:

If you wanted to keep it, I kinda like the idea of replacing Jabba with a hologram of the puppet version. In any of the movies, does anybody ever walk through a hologram? If not, then perhaps it's perceived as being disrespectful to do so...so perhaps if you could come up with a scene where puppet-Jabba gets sort of upset or jumps, you could use that as a hologram, with Han walking through him (at the point where he steps on the CGI Jabba's tail), and hologram Jabba gets kinda testy. It would work as a good example of Han's sort of hardass, "fuck you" nature, while at the same time showing him as not being SO stupid as to step on the real Jabba's tail.

Just a thought.

How could they have cut Vincent Price rhyming? That's inhuman.

But it does explain why his lines have such a lyrical quality to him.

Thanks for the reply Moth3r. You know, the fact that the XØ project would incorporate more than one laserdisc release never even occured to me (I assume SC and DC refer to two different releases, but what the acronyms stand for is beyond me). Very interesting, incorporating the best aspects of each release. So from what I read, (at least) two different laserdiscs were transfered using the XØ player, one disc (the SC version) being rather dirty and having color issues, but having a high degree of detail and good light levels, while the other laserdisc has a clean transfer with good color, but a little soft and lacking in detail due to overblown whites and general fuzziness.

Have I got this straight? (And forgive my ignorance, but what do SC and DC stand for?)

BTW, this process reminds me of an article I read about the restoration of some old Doctor Who episodes from the 70s. The episodes were broadcast in color, but the color masters were destroyed, leaving only B&W 16mm copies. But a fan in the US had recorded the episodes in color on VHS, so when these tapes were discovered recently, the color signal from the tapes was laid over the sharper B&W 16mm transfer.

Nice work guys.
