Psycho (1960): Uncut Version Reconstruction - BD25 |

Project Info
Though the film is groundbreaking for its violent and sexual content for 1960, all the home video releases of Psycho (1960) have been trimmed in three areas for content. (http://www.movie-censorship.com/report.php?ID=1921) While it's unclear whether or not these scenes were in the original domestic release and forgotten over the years, they're worthy of preservation, at least for being in some foreign version.
An open matte SD German broadcast is our only current source for this rare footage.
This BD25 splices in the uncensored footage into Universal's 1080p remastered Blu-Ray release (UK version, used for superior bitrate). The footage from the broadcast has been matted to its proper aspect ratio with a 35mm grain plate added, proper adjustments for contrast and brightness made, and chroma/color noise removed. The footage was also slightly resized (horizontally stretched) to match the dimensions of the UK BD master; honestly, it's unclear which has the proper dimensions.
The quality change is still noticeable, hence my initial reluctance to release this, but it'll do until there's a better source found.
Video - UK Universal BD - 1.85 Widescreen HD Remaster
- German TV Broadcast - Open Matte 480p25 Uncut Version
Audio- English 2.0 LPCM - lossless audio from UK Universal BD, re-encoded with filtered sections from audio reinserted
Screenshots
Comparison (Open Matte SD MySpleen Rip/Uncut Encode)
Footage from UK BD pretty closely resembles source, albeit re-encoded at a lower bitrate to fit in BD25.
Mentioned this in an earlier thread. As stated there, this was just a quick stop-gap release, done until a proper source for the uncut footage can be found.
Project Status
First project complete and released! uperman: Can be found at the usual places...
Final Product
BD25 ISO - 1080p/23.976fps 25 Mbps AVC Vid., 1536 kbps WAV Aud.

Rogue One color grading |

There are avilable online (on youtube and elsewhere) some movie clips from Rogue One; at the moment, the known one seems to be the following:
- Call Sign (00:31) - 1080p 29.97fps
- Come Back (00:23) - 1080p 29.97fps
- Chance of Failure (00:40) - 1080p 23.976fps high bitrate
- Jyn is Rescued (00:48) - 1080p 23.976fps high bitrate
- Jyn Rallies The Rebel Alliance (00:21) - 1080p 23.976fps high bitrate
- Trust Goes Both Ways (00:48) - 1080p 23.976fps high bitrate
- Jyn, Cassian and K-2SO in Jedha City (00:40) - 720p 59.94fps (from a show)
- Jyn, Cassian and K-2SO in Jedha desert (00:18) - 1080p 29.97fps (bits & pieces, no usable audio, from SW Celebration 2016)
for a total of about four and half minutes. WOW, we got 2% of the movie in our hands!
if the available movie clips are reflecting the final color grading that will be present on future BD (UHDBD/DVD) releases (very likely, indeed), then I must say that it is probably not the same seen in theaters…
Left, movie clip untouched; right, regraded using workprint as reference:
Now, it is always possible that the workprint has wrong colors, but I do seem to remember they are quite the same seen on the big screen, and you?

El Mariachi. Original AR / Open-Matte |

Hi Fanres.
Is there anybody out there aware of the best open-matte version of Robert Rodriguez's El Mariachi?
The film was shot on 16mm in a 1.33.1 AR (?) and blown up to 35mm for the general release.
All releases i know of on DVD/BLU are cropped to 16.9 and had to be scanned from a 35mm blowup because the negative was to damaged (information from the DVD commentary).
My Original VHS (Which i no longer possess!) was in 4:3 and (I believe) Open Matte. As were the TV showings in the UK.
According to the LDDB http://www.lddb.com/search.php?search=el...sort=title
The Japanese retaines the full frame, with the other releases cropping to a (less server) 1:66:1 AR
all these releases have Burnt in subtitles.
A search on ebay led me to this version
http://www.ebay.com/itm/El-Mariachi-VHS-...2337482063
and a better PAL version
http://www.ebay.com/itm/USED-VG-El-Maria...Sw-FZXjyA8
Which if 'English dubbed' should means they probably dont have burn't in Subtitles (?).
Does anybody know of the existance of any other versions, or have caps of the versions I mentioned above?
It would be nice to preserve the original version, Just wondering where the best sources are.

Why 1080p is (not always) better than 720p |
Posted by: spoRv - 2016-12-24, 04:13 PM - Forum: General technical discussions

Anyone thinks that definition = resolution. This is not (always) true!
To me, definition is the maximum resolution (in pixel) a given display, or source, could show; so, an high definition image (1080i/p) is made by 1920 (sometimes 1440) x 1080 pixels. Does it mean I have always a 1920x1080 resolution? Think about it... if you take an high resolution source - like a BD made using a 4K master - and compare it with an upscaled DVD, will they look like the same? Obviously not!
So, resolution is not (always) the same as definition... back to the example, if we downscale the 1920x1080 BD image, mastered from a 4K source (hence more than 2x the BD definition) to DVD definition, it should be better than previous DVD of the same movie, but made with a 2K master...
At the end, the resolution of the master used for the source is the most important thing, but not the only factor in the resolution "affaire"... for example, if we have two different HDTV broadcast recordings, one 1080i, and the other 720p, sometimes we discover that the 720p seems better, even if we know that they use the same master (same colors, same cut, same dirt spots placed in the same places etc.); with the hypotesis of a low resolution master (again, resolution <> definition), there could be some reasons for that... - bitrate: a 1080 FHD video has an image size of 1920x1080 = 2073600 pixels, while a 720 HD video has 1280x720 = 921600, so a FHD video file size is 2,25x the HD video (given the same codec is used); if the size difference (minus audio/subs tracks) is much different, and the ratio is lower, than the 720 video has obviously an higher bitrate; there are times where the 720 video has almost the same size of the 1080 one!
- codec: previous comparison has taken in account two videos with different sizes but the same codec; what if one uses a codec and the other another? You should calculate also this factor; roughly, AVC encoded video has the same perceived quality when compressed at half bitrate of an MPEG-2 video: so, if you have an MPEG-2 1080 video, it should be around 4.5x the size of an AVC 720 video to have the same quality
- encoder: different encoders give different results, depending not only on the settings used, but also on the encoder inherent quality; did you know that the best MPEG-2 hardware encoders (the ones used by the professionals) are about 20-25% more efficient than the software ones?
At the end, you should take the previous factors in account to know if an inferior definition video could be somehow better than a superior definition one.
For examples, there are some makers that uses 1080p BD as source for their projects, but release only a 720p AVCHD, saying that the BD resolution is, more or less, equal to a 720p. Again, the resolution is only a factor, and not always the most important... has those AVC 1280x720 10mps video the same quality of an AVC 1920x1080 22.5mbps?
Apparently yes, but there are quality loss in the scaling (unless you watch them in a 1280x720 display), and the eventual grain present will be 2.25x bigger when upscaled, giving the impression of a coarser grain. Even 480/576 video, upscaled properly to 1080, with a grain plate added, encoded at 2.25x bitrate, usually looks better than the 720 version when watched in a 1920x1080 display (projector); will be this difference evident for anybody?
Real answer: it depends... on the display, on the viewer's eyesight, on codec settings... to me, if space is not a concern, I use always the source definition - because, even if apparent resolution seems lower, it could happen that in particular scenes/shots, it stays higher; more, the grain plate applied will have the effective size...
Opinions, personal experiences, interesting articles about all of this?

The importance of screeners |

Warning: I do not endorse nor reccomend the habit to watch screeners only, and then NOT going in theaters AND/OR buying the commercial release!
Said that, a screener (cinema rip, cam rip, telesync... the capture of a movie as shown in the theater) have a certain importance, in particular for us, project maker.
Why? How many times you hear (or you say to yourself) "...but I am certain that scene was (was not) showed" or "the dialog was not the same" and so on... with a screener, you can have a PROOF that this fact is true, or just a memory trick (due to other things like written scripts, trailers, deleted scenes, documentaries, comics, radio dramas etc.)
Now let's see the main things that could make a screener useful (some deeply depending by the screener audio video quality itself): - cut: to know if the movie shown has the same cut released later on media, or if there are additional/cut/different scenes/shots
- color grading: to see the original colors
- aspect ratio: to know the original one
- audio: to hear if the mix is the original one, or if there are added/cut/different music and/or dialogs
Of couse, different screeners are better than just one, to eventually average audio/video quality, or to compare different versions, released, for example, in different countries.
I can write just one example: "Attack of the Clones" and the famous mechanical hand during the wedding scene, different from any successive versions; but there are many others available, and many others will come; so, DO NOT delete your old screener - because you also have the original VHS/LD/DVD/BD etc. RIGHT? - because it could be used as a proof for a project, or just to know if a given fact is true or not!
Last thing: this applies of course also to bootlegs and somehow to workprints.

Time to start a proper thread about this...
Someone *thinks* that the first Japanese squeezed (read: anamorphic 16:9) version, PILF-2187 - does contain both theatrical audio mix AND color grading...
I explored the web and found some links about this edition (and comparisons with other releases as DVD, BD, and even MUSE LD!):
https://www.google.it/amp/s/blog.mercian...t-day/amp/
http://forum.lddb.com/viewtopic.php?f=41&t=2338
As you can see, the trailer (as usual, I could add) has totally different colors from any other versions; also the MUSE LD, as the PILF-2187 as well, while other laserdiscs, DVDs and BDs seems to have, more or less, the same grading... I must admit I like a lot the trailer colors (and the different takes, and unused shots too!) but it's difficult IMHO to use just few shots to regrade a whole movie; MUSE LD, apart some too green images (probably due to the MUSE standard itself) has nice natural colors; can't say which has the "proper" color grading!
A comment in the following page says that, even if PILF-2187 has a different color grading in comparison to any other sources (and it seems true, according to previous pages) and it *seems* almost no corrected in some scenes, it is not the same seen in 35mm:
http://www.ghoulishbasement.com/2012/01/...discs.html
About audio, I think the "original" CDS mix is present in one of the earliest versions on DVD; what about PILF-2187 audio mix?
Time to write your thoughts now!

The Little Mermaid (1989) - Trailer restoration |

Back in 2006 I've re-edited the trailer for The Little Mermaid, but the project was never finished, due the titles. Today the project has been "finished" with the help of taas007. He re-recreated the movie title and credits for the trailer.
You can view the trailer on youtube.
Okay, it's only SD for now. But I'll upgrade it to HD as soon as I get Bambi on BD. When the true finished version is complete, I'll share the HD version here. Till then I hope you'll enjoy the released version nonetheless.
Trailer edited with Final Cut Pro 5.1
