This week on You Asked : Can an old moving picture really be submit in Dolby Vision and Dolby Atmos ? Is built - in TV audio recording ever going to get better ? What to do with an one-time TV . And should you handicap picture processing before the signal get to your TV ?
Are old movies really mastered in Dolby Vision and Atmos?
Mark Nota compose : I ’m presently watch over the 1980 movie Superman II on my Hisense U7 G with a Vizio M serial publication soundbar through my Roku Ultra . It says it ’s in Dolby Vision and Atmos . Can a 1980s movie be in Dolby Vision and Atmos ?
Yes , Mark , it can . Older films can have their video and audio remastered and be presented inDolby VisionandDolby Atmos . However , just because a remastering process is done does n’t mean it is necessarily undecomposed — or that it is as effective as more recent depicted object that ’s been remastered .
From what I infer , moving picture negatives allow for an norm of about 13 block of dynamic image . ( That is , from the sinister parts to the brightest . ) SDR TV allows for about six stopover of active range on average , and the film prints that were played in theater had similar limitation .
Today , HDR allows for about triple the dynamic range of SDR . So , there is plenty of chance to take the original film and create a new , gamey dynamic range master from it . And if you chose to apply Dolby Vision to deliver that HDR , then you could be moderately punctilious about how the last HDR master of that film looked .
Of of course , one could also telephone it in and make something that is only marginally good than the original presentation . It really depends on the quality of the body of work , which usually is subordinate on budget . But , yeah , the original moving picture negative were more subject of hold a higher dynamic range than either the theater mark or the video recording copy were capable to show us . Now that we have HDR tv and HDR delivery mechanisms , we can remaster onetime subject matter enchant on film and present it in HDR .
It ’s a standardised , yet slenderly more complicated story for Dolby Atmos . You technically can create a Dolby Atmos cartroad out of just about any original audio source . But how good that Dolby Atmos experience will be depends some on the source stuff , and some on the budget for the production . The more audio tracks one has to ferment with , the more creative freedom is enable . But in this sidereal day of computer - found sound recording processing , some pretty incredible material can be make using limited original audio resources . So , again , not all Dolby Atmos is equally impressive or even good . But if someone require the time to do it , a Dolby Atmos audio track can be created and present for an old picture show .
Will TV manufacturers focus on improving onboard audio?
Zach Harris writes : Do you think that there will come a point in the future where TV industry start focusing more on their audio for their goggle box lineup ? It stands to reason that one day television picture calibre will hit diminishing returns and there wo n’t be much more to entice customers to elevate . focus on agiotage , enhance audio systems might be one remedy to avail draw in multitude to buy unexampled sets , specially when many citizenry just cease up using their television receiver talker anyway .
You have sex , I do n’t know if there ’s anyone out there who loves getting out the former crystal ball and peering into the future more than I. Here are my mentation on this .
First , I call up we are further away from strain such display nirvana that there ’s picayune way left for improvement . I think the next 10 years at least are going to see more exciting improvements in picture quality . We ’ve catch on-going study on video display technology like electro - luminescent quantum dots ( or so - scream QDEL displays , whichwe blemish at CES 2024 ) and Phosphorescent OLED ( or PHOLED ) , both of which could represent some strong advance in mental picture caliber . I think processing is only going to get honorable as AI and work out mightiness advance . And as bandwidth limitations get down lifting , there ’s an opportunity for one day getting uncompressed picture delivery , and that will be a plot modifier .
All of that is to say : I do n’t see the premise that icon quality strike such a wall that all that ’s leave to entice family to buy a new TV is improvements in audio lineament .
Also , the TV commercial enterprise will keep to thrive by nature of the fact that technical school just finally pall . Far more folks buy Modern video because their former TV breaks . The phone number of TVs sold to straight “ upgraders ” pales in comparison from what I ’m told .
But I consider the material deterrent to improved sound quality in video are a compounding of the laws of physics and consumer preferences .
Here ’s what I mean by that . Despite all the advances that have been made in digital signal processing , digital amplification , and transducer stuff ( that ’s the stuff that speaker are made out of ) , it has n’t been enough to overcome the fact that audio is just moving air , and moving air sound best when it is take at our ears . Also , to fathom their best , loudspeaker need physical blank space .
Consumers have voted against elaborate onboard TV audio systems over and over again . Remember when Sony bookended some of its TVs with matted - control board speaker ? This figure was … not cordially receive , which is why Sony depart doing it . Likewise , A-one - bulky TV do n’t seem to sell as well as thin and wanton TVs . The bottom line of reasoning is that the vast absolute majority of consumer are just hunky-dory with “ good enough ” when it come to sound . And if they want excellent sound , they are willing to jump through some hoops and make some sacrifices to get it .
What should I do with my old TV?
Jolyon Watts indite : What should I do with an quondam goggle box ?
Well , if it is an older CRT TV , I ’d see into selling it . You ’d be shocked how much money previous CRT TVs are go for these Clarence Shepard Day Jr. , mostly because of a rabid retro gaming fan base .
If it ’s an old LCD TV ? Well , again , you could examine sell it for a few bucks . You never know who might be uncoerced to take it off your hands and put it in their garage or put away it in their RV . You could also strain give way it away if it is becoming enough to use , but you ca n’t get any money out of it . Sometimes underfunded schooltime and other institutions can make good use of an older TV that still has some living in it .
Or if nobody seems to desire it , you’re able to rent someone to pick it up and recycle it , or you’re able to haul it down to your local waste direction or recycling ship’s company and dispose of it there . Anything that prevents it from die into a landfill .
LG OLED vs. Hisense U8N?
Kim Strom writes in , saying that they are ready to upgrade from their Hisense U9 gravitational constant and are considering an upgrade to a Hisense U8N , but they are also enticed by OLED and are considering the LG G4 or G3 . They find out a mass of sport — hockey specifically — and are also interested in upgrading in size , from 65 inches to either 77 or 85 .
The first thing that climb up out to me here is that you are search at upgrading to a 77- or 85 - inch TV . And with OLED , the bigger you go , the more you have to give . The climb fee for larger organic light-emitting diode is well gamey than the upgrade to magnanimous LCD - based goggle box .
If monetary value were no object , I ’d say get the biggest LG G3 or G4 you’re able to . But cost is — and should be — a considerateness for most folks .
I ’d say if you have your heart set on OLED , consider go a 77- or 83 - inchLG C3or C4 OLED . That will get you the OLED motion-picture show quality in a large screenland and help keep the cost down . Also , the processing in the C3 and C4 is pretty owing and that dependable processing will help keep your broadcast TV signal await as just as it can at those larger projection screen sizes .
How do I set up my LG TV with Apple TV and a Blu-ray player?
Joseph Green writes : Help ! I ’m in picture manner clink . I have an LG QNED 85 , an Apple TV , and , a Panasonic Disc player . I want to adjust the motion-picture show mode preferences so that I can get the best , most accurate picture . The problem is they all have their own disjoined characterization options . The Apple TV has Dolby Vision . The LG has all kinds of picture modes , and so does the Panasonic . Do they combine when you apply them , or does one overturn the other reckon on what you expend ? How do I set it and forget it ?
The just matter you’re able to do with the Apple TV , in my notion , is to not allow the Apple tv set force Dolby Vision on your television . Some people like the look , but not everyone is a fan of how it establish non - Dolby Vision native content feeling . I deform that off , and then I plant the Apple TV to agree the systema skeletale rate and dynamic range of the depicted object source .
I would n’t use any of the “ movie mode ” on your Panasonic , unless you witness they look better than using your LG ’s picture modes alone .
And this brings up a good message for everyone to learn : Your TV is going to apply processing to the signaling your rootage send , be it an Apple TV , magnetic disk player , Nvidia Shield , or whatever — whether that signal has had processing use already or not . It does n’t know the difference . Sometimes , if you have a TV that is n’t all that ripe , letting your source machine do some processing might aid . But more often than not , the pic central processor in your TV is go to be significantly better than whatever is in that source machine . And since most TVs ca n’t undo processing that ’s already been done , that means it will apply processing to processing , and that does n’t always make for the best outcome .
And on your LG : If you really want the most exact picture , thenFilmMaker Modeis the way to go .
