Empire Strikes back 35mm restoration feedback thread (POUT)
Time

Unfortunately, none of the GUI solutions have worked on my 2017 mac, but as per GZK8000’s suggestion, I googled “Unrar” for command line (Terminal) and got the following two links that will walk you through it:

To get and install UNRAR:

To unwrap the RAR files after installing UNRAR:

Meanwhile, this is beautiful! The reds are pretty intense (as was alluded to earlier in the thread), but it does kind of help Leia look healthier while visiting Luke in the sick bay.

The opening crawl looks a little soft to me. Is that just what it looks like? …And there is obviously some flicker.

Beyond that, what kind of things should I be looking for in order to actually be helpful in this process?

2016 High-Res Star Wars Soundtracks
Time

Well the good news is that it’s a very different sound from the 2016 hi-res copies I have. Very big, great size and weight.

I’ve only given it a casual and cursory listen, but the Empire stuff is a noticeably different presentation than previous releases, with lots of reverb. I’d love to know if it was added recently or if it was retrieved from the original multis (no liner notes come with the HDTracks download), but in any case, on first listen anyway, it sounds pretty great!

PSA the '2016 hi-res soundtracks" are different from the 2018 remasters. The new SKUs that came out the other day are entirely new masters.

It seems like there’s a little confusion in here.

Well that’s interesting! And I’m glad, as the stuff I downloaded (again, possibly not the real deal) was definitely not a good-sounding issue. I guess I’ll pull the trigger at HDTracks and see.

Again, you’re not understanding how Nyquist works.

https://manual.audacityteam.org/man/digital_audio.html
See the part about “sample rates” in the middle of the page.

Forgive me if I rely on my audio recording degree, 15 years as a recording engineer, and 30 years as an audio hobbyist over your ability to google something.

Nyquist stated that to reproduce a certain frequency, you need a sample rate of at least twice that frequency. This doesn’t mean that a higher sampling rate only gives you more high frequencies/more frequency response. It does allow for a wider frequency response, but the point of it is to capture more plot points to reconstruct the signal (as per the chart in the link above).

If you want to tell me more about what I don’t know, feel free to PM me here, but we can stop cluttering up this post with the technical discussion.

the new versions are on hdtracks and tidal. lapti nek is on the rotj album still. wonder why it’s not the ‘special edition’ 2-cd versions of the trilogy from 97/2004

i just got the 1993 4-disc cd set myself

Whoa! I’m glad I responded to this year-old thread - I had no idea they were back up on HDTracks - and actually affordably priced ($13.98 for the 192khz/24bit version)!

It’s a little strange to me that they’re still going with the original 70s album track listings. But I’m also worried that they’ll sound like the earlier set I got.

Meanwhile, the 1993 4-disc is my favorite!

GZK8000 said:
Sampling does not work as you’re describing it. The reconstruction filter reconstructs the original analog signal up to a certain time resolution, which is very high in Redbook audio. I also think the time resolution only depends on the amount of bits per sample, rather than the sampling rate, but I don’t remember where I read that.

It actually does work exactly as I’m describing it, unless I did a poor job above. A 20khz sine wave sampled at 44.1Khz gets exactly 2 samples to describe it. At 192Khz? it gets 8, or quadruples. But the bigger difference is in the dynamic range anyway. Meanwhile, frequency is a time-based phenomenon (cycles per second). The word length determines the bit depth, or dynamic range.

The “reconstruction filter” is just low pass-filter at the analog output. That’s catching the high-frequency spikes, or the “steps” between each sampled part of the wave, and is there to smooth out the rough edges caused by the reconstruction.

Anyway, the purpose of this thread was to ask about the hi-res versions. If you don’t believe that there are real benefits, I’ll refer you to the following website:

Just FYI, “high res audio” is a fraud, a marketing gimmick based on pseudoscience. It is not physically possible to hear frequencies that high. A standard CD already captures everything within human hearing range and then some, after you’ve reached the age you’re likely to care about audio quality your hearing won’t even be able to reach that, and the vast majority of music does not make use of anywhere near the dynamic range supposedly offered by this “higher resolution.” All it does is waste disk space. It’s useful only in studios for purely technical reasons, utterly useless for the end consumer.

Unfortunately, this is misinformed and based on misunderstandings about sound, among other things. There’s nothing “pseudo” about the science, it is what is. While it’s true that humans can’t hear fundamental tones above a certain threshold (20K if you’re a kid, for instance), high frequency response is only part of what’s happening with high res audio. I won’t go into a lengthy discussion about it, but, as an example if you are trying to recreate a waveform, the more plot points you have, the more accurate that waveform is going to be. Higher sample rate = more accurate waveform.

Secondly, all music is extremely dynamic, and while most popular music is compressed and doesn’t make use of 120+ db of dynamic range (nor would you want it to), dynamic range isn’t the entire point. It’s the fact that going from 16bit to 24 bit gives you way, way more info: 16 bit = 65,536 possible volume levels, and with every bit, that number doubles. So at 24 bit, we now have 16,777,216 different volume levels. Further, the digital noise present in every digital recording (the “noise floor”) is moved even further into the background.

Anyway, maybe you don’t/can’t hear the differences - and I believe you absolutely could hear them given the right playback system - but that doesn’t mean the differences aren’t there or that other people can’t hear them.

***** Meanwhile ******

I got ahold of a download purporting to be the high-res release. It’s VERY weirdly different than all other versions I’ve heard of the soundtracks: thin, no low-end… not sure it’s legit, but if it is, it’s bizarre.

It is in two parts, download both and use WinRar or similar to decompress to a single file.

I’m on a mac and I’m having a bear of a time trying to get these open. I generally get “incomplete” or “file damaged” error notices. Is anyone on a Mac able to watch these, and if so, what did you use to unwrap?

The theatrical colors of the Star Wars trilogy
Time

So the reference slide is being scanned, then the resulting digital image (assuming a properly calibrated monitor) is compared to the slide to make sure that what is seen in the monitor matches the slide perfectly? After this is dialed in, we can assume that anything going through the scanning process is accurate, too. I think I have it.

Thanks for the explanation!

Using the scanner and the color calibration slide, I will be able to provide accurate digital color references for a large number of shots of a technicolor print of Star Wars, that I will share with you all through a dedicated thread, where all the scans will be collected. These will naturally be useful for any color correction project for Star Wars in the future. As far as I know no such project has yet been undertaken, and these will thus be the first color references, that will accurately represent the hue, contrast, and saturation of a technicolor print of Star Wars, by using calibrated scans rather than correcting a complete scan of a print by using the projected print as a visual reference.

Is that how a color-reference slide works?

In audio, when you get a tape, there are tones either before or after the progam material that will help you calibrate your equipment for that tape, but the calibration is only for that tape.

I assume film works the same way, in that you’d have a color reference on the same piece of film you’re attempting to color-time. If it works like that, having an outside reference color slide doesn’t seem to be of much value here.

Or am I missing the point of the slide?

Preserving the...*cringe*...Star Wars Holiday Special
Time

GrindhouseGuru said:

What is the version of the special that starts with some of the local news anchors before they go to the special. The one that I guess was a HUGE upgrade that was taken directly from a master videotape. Someone authored a GREAT dvd of this version with menus etc. Is THAT the best quality one? Any help would be tremendous.

I believe you are conflating two versions: The one with the news anchors at the beginning was someone’s fairly clean, first-generation VHS tape from the broadcast on WHIO in Chicago. I believe that one was significant in that it was the first widely-seen version that had the entire, uncut intro to the Special intact, and it was significantly better than other bootlegs that had circulated before. That one has been distributed as a DVD with great menus, etc.

The one from the broadcast master tape was shared by EditDroid and is significant for being far and away the best-looking, clearest version. Being a broadcast master, there were no commercials or station identifiers. For picture and sound quality, this is the best.

Star Wars VHS Rips
Time

It’s funny, I’ve been feeling nostalgic for the 80s video experience as well. Mine was betamax dubs from VHS, and later Superbeta dubs from laserdisc. This was all 1986-87, well before I knew about any widescreen releases.

As kind of a retro project, I just made a VHS dub from the Force Awakens DVD. It’s not the same, being 16:9 with letterboxing, but hearing the electronic buzz of the VCR is kind of cool in its own way.

But to your point, at least the Star Wars (or Ep IV, or ANH if you like) '82 Rental VHS has been preserved. You can find it in the usual places.
