Even if it seems the budget was so low that they cannot afford the two letters, "ty", at the end of the title this little movie is not bad at all!!!
Don't expect multimillion CGI shots, fast action, battles, droids, spaceships etc... so, what is it in this movie? Don't want to spoiler too much, but it has some bits from several films and games like Alien, Doom, Dead Space and many others... story is original, acting is quite good, just pacing is a bit slow, but apart that, it's a good sci-fi movie - not for everyone, but for many... if you like Dante 01 and Cargo, this is a masterpiece in comparison!

Restoration tips: HD matrix surround™ |

HD matrix surround™
What is HD matrix surround™?
It's a discrete multichannel track, originally matrixed in a stereo sound, and then hardware decoded (hence the HD) using the best, and rarer, matrix hardware decoder.
Why?
Because some vintage hardware contains certain dematrix methods different from the usual Dolby Surround, Pro Logic etc. found in every modern decoders; they had that analog sound that could be even better than newer methods.
How does it work?
The matrixed stereo track (usually encoded in Dolby Surround, but could also be DTS Stereo, UltraStereo, CHACE Surround Stereo etc.) is played in the best hardware player (laserdisc, VHS, VHD etc.) using the best cables; the stereo output go in a matrix surround hardware decoder (the older and high-end, the better) to extract at least four different channels (usually Left, Center, Right, Surround) to get a discrete 4.0 multichannel track; those four channels are then captured using two sound cards with a stereo input, one sound card with four discrete inputs, or capture the track twice using a single sound card with a stereo input.
It's possible to get a stereo surround using an hardware stereo synthesizer or a software solution; an LFE could be obtained using a low/high pass filter to route the basses to the LFE and leave the other channels bass-free, either using an hardware or a software solution.
But will it sound better than, for example, Dolby Pro Logic II?
Albeit DPL II is a great matrix surround decoder, some older technology *may* sounds better, or in a different way... at the end:
Quote:Analogue domain matrixing encoding: Dolby Surround (only one spec of its kind there, 4 channels to 2)
Analogue domain matrixing decoding: Dolby Surround
Analogue domain matrixing decoding with steering and individual channel level control through h/w logic (proprietary circuitry depending on manufacturer, with, if at its most basic can decode Dolby Surround as is, then permitted to use logo): Dolby Pro Logic
Analogue domain matrixing decoding with steering and individual channel level control through h/w logic with different emphasis on center and rear for reproducing conventional non-Dolby Surround encoded stereo music tracks: Dolby Pro Logic II
Any hint about which decoders are better?
I've made some researches, and the following are among the best, alternative active matrix surround decoder ever produced:- Shure HTS 5300 / 5200 / 5000 (Acra-Vector technology)
- Fosgate Tate II 101A
- Fosgate Model 3 / 3a / 4 / 5
- Aphex ESP-7000 / Proton SD-1000
- Harman Kardon Citation 7.0 / 5.0 (6-axis technology)
- Lexicon LOGIC 7 (first models)
- Involve Surround Master
avoid Circle Surround I / II and DTS-Neo 6, as a Dolby Pro Logic II seems to be always better than those.
EDIT 2021-08-24:
Even if the original Circle Surround decoder should still be avoided, Circle Surround II seems to be a very improved version - it extracts up to 6.1 channels (L C R LFE Sl Sr Sc)
About DTS Neo 6, there are various versions available: difference lies in particular to the number of bands it splits the signal, but the big problem is that it's difficult (if not impossible) to understand which version a particular decoder uses. According to Disclord, it made a good job upmixing DS encoded tracks.
My last thought: even if DPL I is IMHO the best encoder to get the 4.0 track AS CLOSER as possible to the one heard in the theaters, the others may (or may not) do a good job too; take in mind, though, that the results between different decoders could be slight or huge, hence comparisons should be made.
Is it always possible to use more than one decoder: for example using one for the Left/Right and another for Center/Surround, or add a stereo synthesizer to obtain a pseudo-stereo surround where the decoder outputs just a mono surround.
Notes
Here we are talking about HD matrix surround™ - where HD stands for hardware decoded... of course, we could also have SD matrix surround™ - where SD stands for software decoded; there are some interesting plugins for popular software like Foobar2000, that decode somehow a matrixed track; it's difficult to say how good could be the final result, but it *seems* hardware decoders produce decoded tracks of better quality.
EDIT 2021-08-24:
LAST NOTE: if someone decides to put an HD (or SD) matrix surround™ track on a project, PLEASE ALWAYS STATE which decoder was used!

I'd like to obtain a piece of hardware, but don't know if the seller would like to send it here to Italy... if not, someone who lives in Denver would like to pick up it, and send it to me? Of course, I'll pay the shipping cost!

On board with you guys!
I started collecting fan-edits and restorations from fanedit.org. Then, searching for preservations of THX1138 i searched (and found!) in originaltrilogy.com and, finally, landed here!
Let me tell you one thing, cat-man... your passion for movies is really remarkable. Thanks for all of the time you spend working on your projects.
I'm working on a theatrical letterbox reconstruction for "Interstellar", i hope to finish soon...
Thaks again. Bye!
