Karolo ea 1: HDR le SDR ke eng?
SDR, kapa Standard Dynamic Range, ke maemo a hajoale a lipontšo tsa lifitio le libaesekopo.SDR e hlalosa litšoantšo kapa video e sebelisa lets'oao le tloaelehileng la gamma curve.Lekhalo le tloaelehileng la gamma le ne le itšetlehile ka meeli ea "cathode ray tube" (CRT) e lumellang khanya e phahameng ea 100 cd / m2.
HDR, e emeng bakeng sa High Dynamic Range, ke mokhoa oa ho nka litšoantšo o hapang, o sebetsang le ho hlahisa litaba ka tsela eo lintlha tsameriti le lintlha-khōlō tsa ketsahalo lia eketseha.Le ha HDR e ne e sebelisoa ho nka linepe tsa setso nakong e fetileng, e sa tsoa etsa hore ho be le li-smartphones, li-TV, li-monitor le tse ling.
Karolo ea 2: HDR vs. SDR Ha e bapisoa: Phapang pakeng tsa HDR le SDR
SDR e lekanyelitsoe ke bokhoni ba eona ba ho emela karoloana feela ea mefuta e matla eo HDR e khonang ho e etsa.HDR e boloka lintlha libakeng tseo karohano ea phapang e ka bang tšitiso.SDR, ka lehlakoreng le leng, ha e na bokhoni bona.Phapang e kholo e ka har'a mefuta e fapaneng ea mebala le khanya.Ua tseba, SDR e lumella 'mala oa gamut oa sRGB le khanya ho tloha ho 0 ho isa ho 100nits.Athe HDR e na le mebala e pharalletseng ho fihla ho DCI - P3, moeli o khanyang o holimo oa khanya le moeli o lefifi o tlase oa khanya.Ka nako e ts'oanang, e ntlafatsa boleng ba setšoantšo ka kakaretso ho ea ka phapang, tharollo ea grayscale le litekanyo tse ling, ho tlisa phihlelo e tebileng ho motho ea nang le phihlelo.
Ka mantsoe a bonolo, ha u bapisa HDR vs. SDR, HDR e u lumella ho bona lintlha tse ngata le mebala ea litšoantšo tse nang le mefuta e mengata e matla.Seo se bolela hore HDR e khanya ho feta SDR.HDR e u lumella ho bona lintlha le mebala e mengata litšoantšong.HDR e phahame maemong ana:
◉ Khanya:HDR e lumella ho khanya ho ea holimo ho li-nits tse 1000 le ho theoha ho isa ho 1 nit.
◉ papali ea mebala:HDR hangata e amohela P3, esita le Rec.2020 color gamut.SDR e sebelisa Rec.709 ka kakaretso.
◉ Botebo ba 'mala:HDR e ka ba botebong ba mebala ea 8-bit, 10-bit le 12-bit.Le hoja SDR hangata e le 8-bit, 'me ke ba fokolang haholo ba sebelisang 10-bit.
Karolo ea 3: Litekanyetso tse peli tse ka sehloohong tsa HDR: Dolby Vision, HDR10 le HDR10 +
Haele hantle, ha ho na tlhaloso ea ho qetela ea litekanyetso tsa HDR.Ho na le litekanyetso tse peli tse hlahelletseng tse sebelisoang kajeno, Dolby Vision le HDR10.Ho feta moo, ho na le sebopeho se secha sa HDR10+, se ikemiselitseng ho hlahisa HDR e matla ho maemo a HDR10 ha e ntse e le ntle le borena.Re tla kena ka liphapano lipakeng tsa e 'ngoe le e' ngoe ea lifomate tse peli tsa mantlha tsa HDR tse ka tlase.

Karolo ea 4: Na Setupo sa Hao se khona ho bapala HDR?
Ha u se u hlokometse litaba tsa HDR, ekaba video ea HDR kapa papali ea HDR, u tla tlameha ho etsa bonnete ba hore setup ea hau e khona ho hlahisa litaba tsa HDR.
Mohato oa pele ke ho etsa bonnete ba hore karete ea hau ea litšoantšo e tšehetsa HDR.

Karolo ea 5: Na ho bohlokoa ho ntlafatsa ho HDR?
Haeba u ntse u nahana ka ho tlolela HDR, u kanna oa ipotsa: Na HDR ke letsete le letle?Na theknoloji ea High Dynamic Range e hlile e tla qala?
Leha ho le joalo, ha ho letho le kileng la tiea ka 100%, theknoloji ea HDR e na le lehlohonolo molemong oa eona.Hajoale, theknoloji ea eona ea tlhaho e hokahane haufi le ea tharollo ea litlhaloso tse phahameng haholo, tse tsejoang ka hore ke 4K.
Kaha 4K e ntse e amoheloa ke 'maraka ka kakaretso ka boiketlo le lebelo le tsotehang, hoa utloahala hore HDR e tla latela tsela e tšoanang ho ea pele.Re ka bapisa HDR vs. SDR letsatsi lohle empa hore na HDR e molemo kapa che ho uena qetellong e tla theohela ho phihlelo ea hau ea botho.Hajoale, ikutloe u lokolohile ho hlahloba mefuta e mengata ea ViewSonic ea li-monitor tse lumellanang le HDR-ColourPro kapa ho ikakhela ka setotsoana lefatšeng la khalemelo ea mebala le maemo a mebala.

Ho thoe'ng haeba 4K HDR e shebahala e le lerootho 'me e hlatsuoa ha u bapala?
Ha e bapisoa le SDR (standard dynamic range), HDR e ka etsa hore video ea hau e hlake haholoanyane hape e be joaloka bophelo ka lebaka la mefuta e mengata e fapaneng ea mebala le botebo.Leha ho le joalo, ha ho letho le phethahetseng.Leha litheko tsa thekiso ea lisebelisoa tsa video tsa 4K HDR li ntse li eketseha, li-TV tsa SDR tse ngata, limonita, liprojeke, komporo le mehala li ntse li sebelisoa.
Joale potso ke ena: ha u sheba video ea 4K HEVC HDR 10-bit ho ponts'o e sa tšehetsoeng ea HDR, video ea HDR e tla lahleheloa ke mebala ea eona ea pele 'me e theole khanya ea mebala le ho tlala hohle.Setšoantšo sohle sa video se ne se tla fetoha mosehla.Ke seo hangata re se bitsang mmala o hlatsoitsoeng.
Boitekong ba ho bapala video ea HDR 10-bit ka lisebelisoa tsa SDR, o tlameha ho fetolela HDR ho SDR pele ho felisa bothata ba 'mala o hlatsoitsoeng.LeEaseFab Video Converterke e 'ngoe ea litsela tse ka holimo tsa hofetola livideo tsa 4K HDR ho SDRho 4K/1080p, HEVC ho H.264 ntle le tahlehelo ea boleng ba pono ho khanya, 'mala, phapang le tse ling.Ithute haholoanyane ka likarolo tsa eona tsa bohlokoa:
