Chikamu 1: Chii chinonzi HDR uye SDR?

SDR, kana kuti Standard Dynamic Range, ndiyo yazvino chiyero chevhidhiyo nemabhaisikopo kuratidzwa.SDR inotsanangura mifananidzo kana vhidhiyo uchishandisa yakajairika gamma curve chiratidzo.Iyo yakajairika gamma curve yaive yakavakirwa pamiganhu yecathode ray chubhu (CRT) inobvumira kupenya kwakanyanya kwe100 cd/m2.

HDR, inomirira High Dynamic Range, inzira yekufungidzira inotora, kugadzirisa, uye kuburitsa zvirimo nenzira yekuti ruzivo rwezvose mimvuri uye zvinoyevedza zvechiitiko zvinowedzerwa.Nepo HDR yaishandiswa mukutora mafoto echinyakare munguva yakapfuura, ichangobva kuita kusvetukira kumafoni, maTV, mamonitor, nezvimwe.

Chikamu 2: HDR vs. SDR Kuenzaniswa: Kusiyana pakati peHDR neSDR

SDR inoganhurirwa nekugona kwayo kungomiririra chidimbu cheiyo simba renji iyo HDR inokwanisa.HDR inochengetedza ruzivo mune zviratidziro umo muyero wekusiyanisa wemonitor ungangove chipingamupinyi.SDR, kune rumwe rutivi, inoshaya kugona uku.Musiyano mukuru uri murudzi rwemavara gamut uye kupenya.Iwe unoziva, SDR inobvumira iyo color gamut yesRGB uye kupenya kubva 0 kusvika 100nits.Ipo HDR iine yakafara ruvara renji kusvika kuDCI - P3, inopenya yekumusoro muganho wekupenya uye yakasviba yakaderera muganho wekupenya.Panguva imwecheteyo, inovandudza huwandu hwemufananidzo wemhando maererano nekusiyanisa, greyscale resolution uye humwe hukuru, zvichiunza ruzivo rwakanyanya kunyudza kune ane ruzivo.

Kuzvitaura zviri nyore, kana uchienzanisa HDR vs. SDR, HDR inokubvumira kuti uone zvakawanda zvemashoko uye ruvara mumifananidzo ine simba repamusoro.Izvi zvinoreva kuti HDR inopenya kupfuura SDR.HDR inokutendera iwe kuti uone zvimwe zveruzivo uye mavara mumifananidzo.HDR yakakwirira mune izvi zvinhu:

◉ Kupenya:HDR inobvumira kupenya kumusoro kusvika ku1000 nits uye kudzika kusvika pasi pe1 nit.
◉ Ruvara gamut:HDR inowanzotora P3, uye kunyange Rec.2020 color gamut.SDR inoshandisa Rec.709 kazhinji.
◉ Kudzika kwemavara:HDR inogona kunge iri mu8-bit, 10-bit uye 12-bit kudzika kweruvara.Nepo SDR kazhinji iri mu8-bit, uye vashoma kwazvo vanoshandisa gumi-bit.

Chikamu 3: Maviri Makuru HDR Maitiro: Dolby Vision, HDR10 uye HDR10 +

Chaizvoizvo, hapana tsananguro yekupedzisira yeHDR zviyero.Kune maviri akatanhamara zviyero anoshandiswa nhasi, Dolby Vision uye HDR10.Zvakare, pane itsva HDR10+ fomati, ine chinangwa chekuunza ine simba HDR kune iyo HDR10 chiyero ichisara yehumambo-isina.Tichapinda mumisiyano pakati peese maviri makuru HDR mafomati pazasi.

Dolby Vision

Dolby Vision chiyero cheHDR chinoda kuti mamonitor ave akagadzirwa chaizvo neDolby Vision hardware chip.Pane mari yehumambo yeDolby Vision, inenge madhora matatu paseti yeTV yega yega.Kufanana neHDR10, Dolby Vision inoshandisa Rec.2020 wide color gamut, 1000 nits of brightness, asi inotora 12-bit color kudzika uye inotsigira dynamic data element structure.

HDR10

HDR10 chiyero chakavhurika, uye haufanirwe kubhadhara chero mari kuti uishandise.Nhamba "10" inomiririra 10bit ruvara kudzika.Pamusoro peizvi, HDR10 inokurudzirawo kushandiswa kweyakafara gamut Rec.2020, 1000 nits yekupenya, uye static data processing mode.

HDR10 ndiyo yakajairika HDR chiyero zvekuti vangangoita vese vakuru veTV vanogadzira uye vanopa vanopa, vakaita saSony, Disney, 20th Century Fox, Warner Bros., Paramount, Universal, uye Netflix vanotora HDR10 kugadzira 4K UHD Blu ray disks.Kunze kwezvo, zvishandiso zvakaita seXbox One, PS4, Apple TV inotsigirawo HDR10.

HDR10 vs Dolby Vision - Chii Chinosiyana?

HDR10 uye Dolby Vision maviri makuru HDR mafomati.Musiyano ndewekuti HDR10 ndeye yakavhurika-yakajairwa uye isiri-yemuridzi, nepo Dolby Vision inoda rezinesi uye mubhadharo kubva kuDolby.

Uye nepo Dolby Vision parizvino inokwanisa kugadzira mufananidzo uri nani, hapana maTV anogona kutora mukana wakazara wezvainopa kusiyana neHDR10.

Nekudaro, Dolby Vision inopa iri nani mufananidzo mhando, kunyanya nekuda kweiyo ine simba metadata.

HDR10+

Sezvataurwa pamusoro, pane imwe HDR10+ fomati.HDR10+ ndeye HDR chiyero chakaiswa neSamsung yeDolby Vision, iyo yakaenzana neiyo shanduko yeVision yeHDR10.Zvakafanana neDolby Vision, HDR10 + inotsigira simba data element chimiro, asi HDR10 + chiyero chakavhurika, ichivavarira kuwana zviri nani zvekuteerera-kuona chiitiko nemutengo wakaderera.

Parizvino, HDR10 inodhura-inoshanda uye yakapararira fomati, nepo Dolby Vision ndiyo yekutanga sarudzo.Panguva yekunyora uku, DR10+ zvemukati zvinongowanikwa pane mashoma ekutepfenyura masevhisi (kusanganisira Amazon) uye madhisiki, asi akawanda uye akawanda maTV ari kutanga kutsigira HDR10 +.

Chikamu 4: Iyo Setup Yako Inokwanisa Kutamba HDR?

Kana iwe uchinge waita kuti HDR yako yemukati igadziriswe, ingave iri HDR vhidhiyo kana uye HDR mutambo, iwe unofanirwa kuve nechokwadi chekuti setup yako inokwanisa kuratidza izvo HDR zvemukati.

Nhanho yekutanga kuve nechokwadi chekuti kadhi rako remifananidzo rinotsigira HDR.

HDR inogona kuratidzwa pamusoro peHDMI 2.0 uye DisplayPort 1.3.Kana GPU yako iine imwe yeaya madoko saka inofanirwa kukwanisa kuratidza HDR zvemukati.Sekutonga kwechigunwe, ese Nvidia 9xx akatevedzana maGPU uye matsva ane HDMI 2.0 chiteshi, sezvinoita ese AMD makadhi kubva 2016 zvichienda mberi.

Nekuda kwekuratidzwa kwako, iwe uchafanirwa kuve nechokwadi chekuti zvakare inokwanisa kutsigira HDR zvemukati.HDR-inoenderana zviratidziro zvinofanirwa kunge zvine hushoma hweFull HD 1080p resolution.Zvigadzirwa zvakaita seAsus ROG Swift PG27UQ, Acer Predator X27, Alienware AW5520QF mienzaniso ye4K monitors ine HDR10 yemukati tsigiro.Aya mamonitor zvakare anokonzeresa kurongeka kwemavara muequation mukuyedza kuve nechokwadi chekuti pa-screen mifananidzo inotaridzika seyechokwadi kuhupenyu sezvinobvira.

Maitiro ekuwana HDR Zviri mukati

Panyaya yekutepfenyura, Netflix neAmazon Prime inotsigira HDR paWindows 10. Kana zviri zvimwe zvirimo muHDR, Sony, Disney, 20th Century Fox, Warner Bros., Paramount, Universal, uye Netflix vese vanoshandisa HDR10 kugadzira 4K UHD Blu ray zviri mukati discs.Kana iwe unogona kurekodha yako wega 4K HDR zvirimo nenharembozha, GoPro, DJI, camcorder nezvimwe.

Chikamu 5: Zvakakodzera Kukwidziridza kuHDR?

Kana iwe uri kufunga kusvetukira kuHDR, unogona kunge uchinetseka: HDR imari yakanaka here?Ko High Dynamic Range tekinoroji ichasimuka here?

Kunyange zvakadaro, hapana chinombove 100% chokwadi, HDR tekinoroji ine rombo rakanaka.Parizvino, tekinoroji yayo yekuzvarwa yakasungirirwa padhuze neiyo yekupedzisira-yepamusoro tsananguro resolution, neimwe nzira inozivikanwa se4K.

Sezvo 4K iri kutorwa nemusika wepasirese zviri nyore uye nekukurumidza, zvine musoro kuti HDR ichatevera nzira imwe chete kuenda kumberi.Tinogona kuenzanisa HDR vs. SDR zuva rose asi kana HDR yakakunakira iwe pakupedzisira ichaburuka kune yako pachako ruzivo.Parizvino, inzwa wakasununguka kuongorora ViewSonic's emhando yeHDR-inoenderana ColorPro monitors uye kana kunyura zvakadzika munyika yekugadziriswa kwemavara uye kugadzika kwemavara.

Neraki kune vese vekutanga vanotora kunze uko, HDR zvigadzirwa hazvina kuoma kuuya nazvo.Mabhenefiti eHDR anotowedzera mukutamba nekukubvumidza iwe kuti uone zvimwe zvakawanda mumitambo yako kuti uwane kunzwa kwechokwadi.

Ko Kana 4K HDR Ichiita Seyakasvibira uye Yakashambidzwa Kunze Pakutamba?

Kuenzaniswa neSDR (yakajairwa simba renji), HDR inogona kuita kuti vhidhiyo yako iwedzere kujeka uye sehupenyu nekuda kwehuwandu hwakakura hwemavara nekudzika.Asi, hapana chakakwana.Kunyangwe mavhoriyamu e4K HDR edhidhiyo ekutengesa ari kuwedzera, asingaverengeke maSDR TV, mamonitor, mapurojekita, desktop uye mafoni achiri kushandiswa.

Saka heunoi mubvunzo: kana iwe uchiona 4K HEVC HDR 10-bit vhidhiyo paHDR isingatsigirwe kuratidza, iyo HDR vhidhiyo inorasikirwa neyayo yepakutanga ruvara uye kushatisa kupenya kwemavara & saturation.Mufananidzo wose wevhidhiyo waizova grey.Ndiro ratinoti washed-out color.

Mukuda kutamba zvakare HDR 10-bit vhidhiyo paSDR zvishandiso, unofanirwa kushandura HDR kuita SDR kutanga kuti ubvise yakagezwa-kunze ruvara nyaya.UyeEaseFab Vhidhiyo Converterndiyo imwe yenzira dzepamusoro dzekuitashandura chero mavhidhiyo e4K HDR kuita SDRmu 4K/1080p, HEVC kusvika H.264 pasina kuoneka kunaka kurasikirwa pakupenya, ruvara, kusiyana nezvimwe.Dzidza zvakawanda nezve akakosha maficha:

◉ Gamuchira marudzi ese e4K HDR mavhidhiyo, zvisinei kuti anobva kupi uye kuti anoshandisa encoding fomati ipi.
◉ Shandura mavhidhiyo e4K HDR kuita MP4, H.264, HEVC, MOV, AVI, FLV, iPhone, iPad, HDTV, Xbox, PS4 uye 420+ preset profiles.
◉ Dzvanya 4K resolution kusvika 1080p /720p kana upscale HD kusvika 4K zvakanaka pasina kurasikirwa kwemhando.
◉ Super-inokurumidza vhidhiyo inoshandura kumhanya & 100% mhando yakachengetwa nerutsigiro rwekukwidziridza Hardware uye yemhando yepamusoro injini.
