| UHD BD to BD? |

I've noticed an unpleasant trend lately. Studios are releasing new 4k transfers with HDR and wider color gamut, etc. and then simultaneously pooping out either a repackaged old transfer or intentionally degraded version of the new transfer as 1080p discs at the same time.
Sometimes the colors are worse for no legitimate reason, frequently they are scrubbing grain like it's 2008.
What is clear from screenshot comparisons is that you can maintain a lot of the improvements of the 4k releases without the actual UHD enhancements.
Anyway, being a staunch anti-4k/HDR person, I've been wondering what would be involved in creating new 1080p discs using the UHD BDs as a master.
I honestly haven't the slightest idea where to start or what software is capable of it. I'm aware the HDR needs to be tone mapped(?) to SDR... and that's about it.
Case in point, The Mummy Trilogy got a recent 4k release that looks great. Except most people agree the film doesn't have 4k worth of detail. The similarly packaged BDs that came out this year are the same 10 year old transfers they keep repackaging.
What might a UHD to BD conversion look like? Check out these screenshots: http://forum.blu-ray.com/showpost.php?s=...count=1579

Time to write something about this gorgeous display, after I watched it for few days; of course, these are first impressions and, if something new will be discovered during the next weeks/months, I'll add some comments.
Note: TV was tested using mainly HD sources (BD and HDTV) and some SD ones (DVD and SDTV), all obviously SDR.
Panasonic TX-58DX900 (a.k.a. TX-58DX902B)
there are a lot of reviews about this TV, but I put a link to one of the best ones: https://www.hdtvtest.co.uk/news/tx58dx90...174282.htm - I agree with almost everything, but I want to add my own opinions here.
Design
I was not sure about it, but now that I got it, I must admit it's quite beautiful. Yes, it's not the most thin TV - and surely its stand doesn't help - but coming from old FALD sets (Samsung before, and its almost-clone Toshiba after, both 55') that were about 10cm deep, and with a (relatively) huge frame, this is very elegant, with just two small "feet" visible on the front. I decided to leave it on its stand, even if it has a 6 degrees inclination.
Small note on its stand: this is very wide, almost as the TV, so you need a wide TV stand; some think it's a problem. But, really, do you think it's a nice thing to put a, let's say, 130cm wide TV on a 50cm stand, in a T-shape? Mmmhhh, I don't think so - always put a TV over a stand wider than it, as IMHO is more pleasing to the eye than the contrary.
Its screen is highly reflective, so avoid to put it right in front of a window; even if it could be seen as a cons, this help (I think) to achieve deep blacks, of course along with VA panel and ABC (Automatic Black Control). It's a pity the power cord can't be detached, but it's just a very minor problem.
Main remote is great, heavy, with backlight (sadly not for all the keys); secondary remote is nice, but I have not used it so much - I think it could be used as an easy channel and volume +/- for the elderly (so, perfect for me in the next few years!  )
Connections
They are enough to connect any digital source; it's a pity there are no SCARTs and S-Video plugs, and that the only analog connection (component or composite) forces to let the back panel detached... the best solution would be to connect an external video processor with multiple analog ins and one HDMI out, so you get more analog sources, eventual better comb filter and/or upscaling and video processing, and the back panel in place.
Operation
Frankly, there are so many options - some available only with certain sources/modes - that I was overwhelmed; there is also a help menu, so for most of them you could find a simple explanation. Happy to have many options and don't use it, instead having few and need further ones. The only advanced option I missed a bit from the old Toshiba is the possibility to switch on or off red, green, blue subpixels, useful for calibration.
Calibration
Still had no time to calibrate it - just connected to the PC, but with only slow mobile connection, sadly... I'll get soon one of my forgotten HDD with calibration patterns, so let's skip this for the moment. I can say that some modes (mainly Professional 1 and 2) are great out of the box, so I used them for both TV and digital sources (BD and PC).
Black Level & Contrast
Used to old LED FALD models (which used the same panel) with only 96 zones, the step up to 512 zones is quite noticeable. Sure, if you watch a test clip made mainly to discover FALD zones number, you will note blooming (of course smaller than models with less zones) or the difference in brightness in the white box over the black background, but I noted it only once during closing credits, where a big logo inside a white box had noticeable brightness variations during vertical pan. Apart that, and other focused demo made to show the strenght of other technologies (like plasma or OLED), and of course during closing credits (that nobody watch, by the way), watching movies blooming almost never occours; I watched the "guilty" star field in "The Martian", but it was not as bad as described in the review - probably OLED could do better, but it has other, different problems (for the moment).
Backlight & Screen Uniformity
Setting backlight at 10 (from 0 to 100) on a dark room works well; I noted that some modes, with exact settings, have inky black (read: 0nits) while others have not - for example, Professional 1 has 0nits while 2 has not... of course, ABC *must* be switched on, or you can just buy a "simple" edge lit LED instead. Usually setting it at low avoid black crush, still getting a great black (depending on mode used).
Virtually no DSE (dirty screen effect) noted, apart on few occasions mostly on low bitrate SDTV broadcasting, so probably those were also due to the source. Many posts on various forums talk about two vertical banding on both sides of the screen, but I never noticed them. I did instead noticed in very limited occasions banding due to local dimming technology - the worst offender was AVP: Requiem, during the first minutes, on horizontal pan after the aliens in the glass tubes; I guess this could happen in so few instances that you could live with it.
Motion
I mostly watched material with any IFC (Intelligent Frame Creation) setting off, but lately I used custom, with Clear Motion switched on; still figure out how good it is (and if it's better with or without it), but I used it with Toshiba, and noted a better motion handling, so I guess this will be the same. But it's great to have various settings within IFC sub menu, to get the best possible motion control.
Viewing Angle
This could be an important decision point: even if I did not noticed a so terrible drop in contrast and/or saturation as mentioned in the review and elsewhere, it is there - due to inherent VA panel technology; so, if you watch it directly in front of it, and other family members and friends on both sides can't notice it (a lot), go for it; at the contrary, get an OLED - do NOT get an IPS panel LCD (IMHO!)
UHD HDR, 3D, gaming
not tested (yet); further impressions will be posted ASAP. I do only noted that input lag is around 38ms without ABC, which is the same of my previous sets, so I'm pretty sure it will be as good as them for gaming.
Other thoughts
Sound: old 10cm deep FALD TVs have (quite obviously) a good audio, and this is no exception - even if it's "only" 6cm deep. Do not expect an home theater quality level, but it is waaay better than any edge lit LCD or OLED TV! It's also good for listening radio - you can even switch off screen.
Overall video quality: stunning!
Colors are always well reproduced; it must be noted that it's possible to change color gamut - Rec. 709, SMPTE-C, EBU, Rec. 2020, DCI - and often, if not always, setting DCI with BD is better than using 709 (as should be); maybe due to the fact BD are usually graded using DCI gamut?
HDTV broadcasting is great, in particular live action and sport. But also very good SDTV sources are rendered in high quality - the upscaling job of this set is incredible, considering it should resize a small SDTV from "mere" 0.4mp to more than 8mp. Strangely, sometimes SDTV is better than DVD, but I guess it's due to low compressed and live action SDTV Vs high compressed DVD. I was worried to watch SD sources on a UHD set, due to huge difference in resolution, but now I'm pretty pleased with results; of course, you can't get an high definition image from a standard definition source, but it is more than watchable, and, with right high quality sources, I'm very satisfied; internal upscaler does its job very well.
Blu-ray is simply perfect. Have not the occasion to make a direct comparison with UHD-BD, but I did an half screen comparison using UHD source (not HDR) and its BD counterpart, and they were very close - I sit at less than 2mt, so maybe sitting closer could reveal more details in the UHD source... let's wait for further tests.
Skyline BD: great, SFX and live action blend perfectly, no defects detected.
Speed Racer BD: one of the most colorful movie ever made; artistic value could be debatable, but technically is an eye candy; again, I watched it carefully to spot eventual problems - blooming, banding, DSE... nothing detected. Watched half in daylight, half during the night... nothing!
Hotel Transilvanya 2 BD (2D): first vision for me; not so funny as first episode, still nice; visually perfect, except a light DSE during one horizontal pan - maybe due to mode used, THX instead professional.
European Song Contest final HDTV: well, this was great! I watched last year final on the old Toshiba but only in streaming; so, this time with higher bitrate, this was even better - and music was on par with image.
Use as PC monitor: happily, my old GTX760 support 3840x2160@60fps, sadly only 8bit, but 4:4:4. Great monitor, anything that before could be barely spotted as pixelated (like diagonal lines) now seems drawn - you get the point...
Final considerations
Coming from older FALD TV sets, and still owning a plasma TV (Full HD, albeit not one high end model), I was pretty aware of pros and cons of buying a FALD LED LCD model in 2018; I'm not crazy (am I?) to have preferred this to an OLED TV... no edge lit LED set taken in serious consideration, mostly due to their black level and screen uniformity.
First, price - bought used (but perfect, as brand new) with few operation hours at 950€, where new MSRP was almost 4000 at the very beginning, then repriced lower and lower until about 1600€ today (if ever available), I think it's a great price/quality ratio, surely better than any OLED brand new model - which is more than 2000€ for comparable quality, not taking in account basic LG models - and they are "only" 55'.
Second, image retention. I know the problem is not so bad as in the past, still it's present, and didn't want to risk a permanent burn in, as I use it as PC monitor for so many hours each day. Never had such problem during seven years using previous FALD LEDs.
Third, motion. Even if without motion setting "helps" this and OLED have 300 lines of motion resolution, when those help are engaged OLED top at 650 lines, while this one get 1080 lines. I'm quite sensible to motion handling, so this is very important.
Fourth, top brightness. Sure, OLED has perfect black, and will never have blooming problems; still, in over 99% of the times the black is inky as OLED (I think about black bars during movies, for example) without noticeable blooming; plus, top brightness is unbeatable for the moment - in particular with HDR.
So, at the end, I can live with occasional blooming and banding, while viewing angle is not a problem for me. Sure, next display will likely be not an LCD, but will be an OLED or a Crystal LED or another technology. But, for the moment, this is the best compromise for someone who uses it mainly as a PC monitor, that wants good motion, and high brightness.

| VHS Formatted to fit your TV ? Fullscreen or Widescreen |

I'm collecting VHS, primarily Fullscreen, I occassionally come across titles that, rather than stating that they are Fullscreen or Widescreen, say they are "modified to fit your TV" Anyone have any experience with this, what does it mean? Currently looking at Requiem For a Dream, edited version, description - Canadian Home Video. " The film has been modified from it's original version. it has been formatted to fit your TV." I have brilliant Toshiba TV from 1999, which I still use for VHS.
Regards Glastontown.

| UHD Releases but still the extras are in SD? |

I have not yet or I am yet to migrate to UHD... I have a UHD TV with HDR and I will eventually start buying in to this format I suppose.
But when it comes to getting a UHD release ok, I own every film I practically I want to own in SD or HD, If I want it in UHD It will have to be something I really care to own in UHD because of the price tag. And the player costs...
But all these releases still have all the bonus content in Standard definition... How stupidly lazy still keep adding the same old Bonus SD content without re-scanning the bonus material and upgrading that also.
So it's as if there is no budget for HD Deleted scenes or documentaries only the films themselves and that really is a bummer.
It does not really make me want to re-buy any films that I really admire at all... I don't feel any draw towards UHD when I look at the extras and they are all in SD... And also nothing new is being offered.
Considering I also churn these days at about 4 or 5 new films a year I really like...
DVD was amazing when it first hit and it still carries on surviving and Blu-ray has not killed it off and also UHD won't kill it off...
So what will kill off DVD and the Special features from the classics you love... Because only the films get a job and most of the time people complain about it looking different and also everything in the bonus section is just ported straight over in SD anyway.
What reason to keep buying the same if nothing new is offered?
