Death Sentence Unrated (2007) |

When Death Sentence was released on DVD there were two versions, Unrated and R Rated. The blu ray release unfortunately only contains the R Rated cut. Just to clarify there is an unrated released on blu in France and possibly other places, but it uses Upscaled SD footage as opposed to true HD footage. This project is a full HD restoration of the Unrated cut.
The main source of the video is the German Concorde Blu Ray. This seems to be the best blu ray out there as it is 1080P and has DTS HD audio (only High Resolution for English not Master Audio) but it's better than Dolby Digital like the UK disc. The French disc seems to have DTS HD Master Audio but I don't have this and I do wonder what real world difference it will make.
The source of the unrated scenes is a webrip from Amazon Germany, 1080p with German AC3 and English AC3 640 kbps.
The blu ray was used where possible, unrated scenes have been cut in, in some places just the unrated audio was used. To my ears the audio matched up quite well, I had to boost the volume in one of the unrated segments. The English and German audio were both exported and encoded as 5.1 DTS-HD MA.
Details of what is extra can be found here:

Splash (1984) Trailer |

Anyone have a decent copy of the original theatrical trailer? This is the only copy I've been able to find on YouTube, but the quality is just horrible. I've started a new YT channel to update old trailers to HD that don't have good versions, and I'd like to do this one next. But a LITTLE better quality would go a long way toward helping me do that. Any help would be greatly appreciated.

I also need help identifying the last two pieces of music in the trailer (from 2:04 on) if anyone knows what they are.

How lossy is a lossy audio codec? |

I decided to start this thread because I always read certain claims, by codec producers and/or users, about alleged subjective transparency of lossy codecs at really low bitrates; last of them was by MPEG-H (that uses AAC) that set transparency level at 96kbps per channel - that is 8 times less than uncompressed LPCM.
Now, how can anybody find out how lossy is that codec, or any other? And, what does it mean "subjectively transparent"?
According to Wikipedia:
Quote:In data compression and psychoacoustics, transparency is the result of lossy data compression accurate enough that the compressed result is perceptually indistinguishable from the uncompressed input. In other words, transparent compression has no perceptible compression artifacts.
Then, a given codec compressed using a given bitrate and/or setting could sound transparent to me, but not to someone else, or could sound transparent when played in a portable audio player and earplugs but not on a hi-fi system.
Said so, if I "lock" certain variables - subject: me, sound chain: always the same - how can I state a given codec is "subjectively transparent"? And, which could be "more transparent" than another?
I thought about several ways to compare original and lossy encoded files:- listening tests - just play one after the other (possibly with an ABX method)
- waveforms - using Audacity, looking for difference in waveform shapes
- spectrum analysis - using Spek (or Audacity etc.) looking for difference in frequency and loudness
- audio difference - using Audacity, load first original file; then load encoded file; if stereo, divide each track in two mono tracks; invert phase in one file; playing both (one in phase, one out of phase) will lead to cancel similar sound, leaving only the difference
I made several tests, and a lot of surprises arose; although all codecs (at reasonable compression settings) sound more or less good, and their waveforms seems quite similar; still, when spectrums were compared, a lot of differences came out, as well as in the last test; sound transparencies were rarely achieved at claimed bitrates for many codecs.
Conclusion: taken in account that more or less all lossy codec sound "nice" around reasonable compression ratio that start from ratio 8:1 (depending on codecs), and almost all sound good around 4:1, and their waveforms are very similar, personally I prefer the codecs that does not cut high frequencies - even if some can't hear higher frequencies, it doesn't mean an encoded files should discard them - and, between them, I decided to favour the ones that have less audio differences.
Note: psychoacoustic techniques used in many modern lossy codecs help to lower bitrate, but introduce often audible artifacts not found on older codecs - maybe there is a reason while Auro decided to not use them in their Octopus codec!
PS: despite someone still claim, in 2020, superior quality of certain lossless codecs, they indeed sound ALL EXACTLY THE SAME (if played through the same chain of source-cables-amplifier-speakers, of course); hence: FLAC, DTS-HD, MA Dolby TrueHD etc. when decoded are all identical, bit by bit, to the uncompressed source.

Do you lose EX when editing 5.1EX? |

Maybe a dumb question here... If I want to edit the 5.1EX DD (first coverting it to wav files), will I lose EX after I render it out as 5.1 pcm when done? I guess you don't since the EX is encoded into the rear surrounds with an algorithm. Or am I wrong?

List of BDs sourced 16/35mm theatrical prints |

I imagine there's quite a ton of them out there, mainly more obscure and cult films. Though here's some off the top of my head:
Snappy Video BD of Dracula and His Vampire Bride.
Dark Star (Bryanston Pictures logo suggests a faded 35mm blowup print was used and then sandblasted with degraining).
The Last Valley (IP was in abysmal shape and Kino reportedly used two different 35mm prints, one from the BFI and another being Joe Dante's personal copy).
Umbrella BD of Body Melt (their 4k transfer was based on a battered 35mm Aussie release print that rights holder Beyond Entertainment had. Vinegar Syndrome later found the 16mm OCN somewhere in Canada and did a 2k scan/restoration of that. Their transfer was used on the VS Blu as well as the UK/German BDs).
The Man From Hong Kong.
Japanese Extended cut of Police Story (found on the Eureka UK Blu as an extra).
Hong Kong theatrical cut of Police Story II (found on the Criterion Collection Blu as an extra).
The Leg Fighters.
Dynamo, known as Bu Ze Shou Duan (both HK and shorter cuts are sourced from a combination of various theatrical prints and one loaned from Quentin Tarantino's personal collection).
Japanese extended cut of Heart of the Dragon, titled The First Mission (can be seen in it's entirety on the Japanese Shochiku Blu. Note the UK 88 Films Blu has this version reconstructed with bulk coming from Fortune Star remastered footage of the HK theatrical cut).
Japanese extended cuts of Fists of Fury, Way of the Dragon, and Game of Death (the former two are only complete on the Japanese BDs as extras, while the US Shout Factory Blus have the latter in full as an extra).
German BD of The Reflecting Skin (comes from German dubbed and localized 35mm theatrical print).
German BD of One Eyed Jacks (WARNING: horrible PAL DVD upscale from battered French theatrical print).
