Auahatanga i roto i te Pouaka Whakaata me te Hangarau Dolby Vision
Kua tere haere ngā whanaketanga o te pouaka whakaata i roto i te tekau tau kua pahure ake nei. Ahakoa i aro nui ngā whakapainga kounga pikitia ki te taumira - mai i te SD ki te HD, kātahi ki te 4K - kua nekehia te aro ki ngā āhuatanga e whakatau tata ana i te "ahua" o te tirohanga: te tae, te rerekētanga, me ngā taipitopito i ngā wāhi mārama me te pōuri. Koinei te wāhi e whai wāhi nui ai te hangarau High Dynamic Range (HDR), ā, ko tētahi o ngā paerewa HDR rongonui me te whānui e whakamahia ana ko Dolby Vision. Ehara i te mea ka mārama ake ngā whakaahua i tēnei hangarau, engari ka tukuna he wheako mātakitaki e tata ana ki te tirohanga a te kanohi tangata ki te ao tūturu.
He aha te Dolby Vision?
Ko Dolby Vision he hangarau HDR i whakawhanakehia e Dolby Laboratories hei whakapai ake i te kounga o te pikitia mā te arotau i te whānuitanga hihiri, te tika o te tae, me te kanapa o te mata. He rerekē ki te HDR "noa", e whakamahi ana i ngā tautuhinga whānui ake, ka whakamahia e Dolby Vision te ariā o ngā raraunga hihiri—ngā mōhiohio e whakaatu ana ki te pouaka whakaata me pēhea te whakaatu pai i ia whakaaturanga, tae atu ki ia anga.
Arā, ehara a Dolby Vision i te "aratau pikitia" noa iho, engari he pūnaha e whakahaere ana i te hononga o ngā ihirangi ki ngā āheinga o te mata. Nō reira, ka mau tonu ngā taipitopito i ngā tirohanga pōuri me te kore e memeha, engari ka noho koi tonu ngā wāhi kanapa pērā i te kanapa o te rā, i ngā rama neon rānei me te kore e "pōuri" (he mā rawa, he ngaro hoki ngā taipitopito).
He aha te take he peke nui te HDR mō te pouaka whakaata?
He tokomaha te hunga e whakaaro ana ko te kounga o te pikitia ka whakatauhia anake e te taumira. Heoi, ahakoa te taumira 4K, ka taea te ahua papatahi mena kaore i te tika te whakahaere i te rerekētanga me te tae. Ka whakawhānui ake te HDR, tae atu ki a Dolby Vision, i te awhe i waenga i ngā pūwāhi tino pōuri me te tino kanapa ka taea e te pouaka whakaata te whakaatu. Ka hangaia e tēnei ngā whakaahua e:
1. He tūturu ake: He āhua tūturu te āhua o ngā whakawhiti mārama-pōuri.
2. Ētahi atu taipitopito: Ka kitea ake te kakano i roto i ngā atarangi, i ngā kapua mārama rānei.
3. He kanapa ake: He ātaahua ake te āhua o ngā tae, engari he tika.
I roto i te mahi, he maha ngā wā ka "whakamiharo" ake te HDR i te whakapiki ake i te 1080p ki te 4K, ina koa ka mātaki ana i ngā kiriata he kaha te hanga pikitia.
Ngā painga o Dolby Vision ki te HDR10
Ko te hōputu HDR tino rongonui i te mākete ko te HDR10. He maha ngā take matua e kiia ana ko Dolby Vision he pai ake:
1. Ngā raraunga hihiri
Ka whakamahia e te HDR10 ngā raraunga tūmau, arā, ka whakamahia ngā tautuhinga HDR puta noa i te kiriata, i te wāhanga rānei. Ka whakamahia e Dolby Vision ngā raraunga hihiri, e āhei ai te pouaka whakaata ki te whakarerekē i te whakaaturanga i runga i te tirohanga-ki-te-whakaaturanga, i te anga-ki-te-anga rānei. He mea nui tēnei nā te mea he maha ngā rerekētanga o te māramatanga o ngā kiriata: he pōuri tetahi tirohanga, kātahi ka tino kanapa tetahi atu. Ka arotauhia e ngā whakarerekētanga hihiri ngā mea e rua.
2. Te kaha ki te whakanui ake i te hohonutanga o te tae
Kua hangaia a Dolby Vision hei tautoko i ngā hōhonutanga tae teitei ake (hei tauira, 12-bit i roto i te whakatakotoranga), ka hua ake he maeneene ake ngā panonitanga tae me te whakaiti i ngā here (ngā rārangi i te rangi, i te atarangi rānei). Ahakoa he maha ngā taputapu kaihoko e tautoko tonu ana i te 10-bit, ka whakaratohia e te paerewa Dolby Vision he anga mō te kounga ōrite ake.
3. Te arotautanga oro matatau ake
Ko te mahere oro he tukanga whakarerekē i ngā ihirangi HDR i hangaia mō ngā taumata kanapa motuhake kia rite ki ngā āheinga o tō pouaka whakaata kāinga. Ka āwhina a Dolby Vision i ngā pouaka whakaata ki te mahi i te mahere oro kia tika ake, kia kore ai e ngaro ngāwari ngā taipitopito o te māramatanga me te atarangi.
Me pēhea te whakarerekētanga a Dolby Vision i te wheako mātakitaki?
Ko ngā pānga o Dolby Vision ka tino kitea i ngā ihirangi he tino rerekē te tae, pērā i:
– Kiriata pūtaiao-pūrākau me ngā rama neon me ngā wāhi pōuri
– Ngā tirohanga pō me ngā puna mārama iti (rama, kānara)
– He kiriata pakiwaituhi me te whānuitanga o ngā tae
– He pakipūmeka mō te taiao me ngā rangi kanapa me ngā taipitopito atarangi i roto i ngā rākau
I runga i tētahi pouaka whakaata Dolby Vision, ka kitea te kanapa o ngā whakaata mārama i runga i ngā mata wai, engari e mau tonu ana ngā taipitopito. I tētahi atu taha, kāore ngā tirohanga pōuri e huri hei poraka pango; ka mārama tonu ngā taipitopito o ngā kākahu, o ngā makawe, me ngā papamuri. Mā tēnei ka māmā ake te whai i te kōrero, ā, ka rumakina ake ngā tirohanga.
Te tūranga o Dolby Vision i roto i te pūnaha pouaka whakaata hou
Ehara a Dolby Vision i te hangarau motuhake. He wāhanga ia o tētahi pūnaha pouaka whakaata hou e whai ake nei:
1. Mata me te kanapa teitei me te rerekētanga kaha
Hei whakatutuki i te Dolby Vision, me whai taputapu kaha te pouaka whakaata: he panera he kanapa teitei, he tika hoki te whakahaere rama. He pai ngā pouaka whakaata OLED i ngā pango pouri, ko ngā pouaka whakaata LED ia he pai te whakaiti i te kanapa o te tirohanga. Ka taea e Dolby Vision te mahi tahi me ngā mea e rua, engari ko te kounga o te panera ka pāngia tonutia e te hua whakamutunga.
2. Te rere o ngā ihirangi me ngā ratonga
He maha ngā papaaho roma ora e tuku ana i ngā ihirangi Dolby Vision, inā koa mō ngā kiriata roa me ngā raupapa. Heoi, ka rerekē pea te wātea mai i runga i te rohe, te mahere ohaurunga, me te taputapu purei. Ko te tikanga o tēnei, ka whai hua anake te auahatanga Dolby Vision ina oti katoa te mekameka purei: ngā ihirangi tautoko, te taputapu tautoko, me te pouaka whakaata tautoko.
3. Ngā taputapu kaitākaro me te hononga
Haunga ngā pouaka whakaata, me tautoko hoki ngā taputapu pēnei i ngā pouaka roma ora, ngā papatohu, ngā kaitākaro Blu-ray rānei i a Dolby Vision. I ētahi wā, ka tautoko te pouaka whakaata i a Dolby Vision engari kāore te kaitākaro, nō reira ka whakahekehia pea te hōputu HDR e whakamahia ana ki te HDR10.
Ngā wero me ngā mea hei aro atu
Ahakoa he maha ngā painga o Dolby Vision, he mea nui ētahi hei mārama:
1. Kāore e pai ake te āhua o ngā ihirangi katoa
Ki te kore te ihirangi e whakaputaina me te whakatauranga HDR pai, ka kore pea ngā hua e puta. He āwhina a Dolby Vision, engari kāore e "whakaari" i te huri i te rauemi kāore i te tino pai ki te kounga tino pai.
2. Ngā rerekētanga o te kounga i waenga i ngā pouaka whakaata
E rua ngā pouaka whakaata e tautoko ana i te Dolby Vision, ā, ka rerekē ngā hua e whakaatuhia ana nā te rerekētanga o ngā panera, ngā tukatuka whakaahua, me ngā taumata kanapa.
3. Ngā tautuhinga whakaahua me te aratau tika
Ka taea e ngā momo pikitia kua tukatukahia rawatia (pēnei i te tino mātotoru, te koi nui rānei) te whakaiti i ngā painga o Dolby Vision. He maha ngā pouaka whakaata e tuku ana i ngā momo "Cinema" "Filmmaker" rānei e whakaata pai ake ana i te whakaaro o te kaihanga.
Te heke mai o te pouaka whakaata: te kounga pikitia "mātau" e piki haere ana
He tohu hou a Dolby Vision mō te auahatanga pouaka whakaata: ehara i te mea ko ngā whakatakotoranga tau anake, engari ko te mahere atamai i ngā whakaahua hei arotau i ngā ihirangi puta noa i te whānuitanga o ngā taputapu. I ngā rā kei te heke mai, ka kite tātou i te whakaurunga pakari ake i waenga i:
– HDR me ngā raraunga hihiri
– Te whakanui ake i te AI mō ngā ihirangi ehara i te 4K
– Ngā tautuhinga whakaahua urutau i runga i ngā āhuatanga o te rūma
– Ngā paerewa whakaputa ihirangi e piki haere ana te ōrite
I roto i taua anga, ko Dolby Vision tētahi tauira o te huarahi e taea ai e te hangarau te hono i te āputa i waenga i te whare mahi toi (te wāhi e hangaia ai ngā ihirangi ki runga i ngā mata ngaio) me te rūma noho (he rerekē ngā āheinga o ngā pouaka whakaata).
Whakamutunga
E whakaatu ana ngā auahatanga pouaka whakaata me te hangarau Dolby Vision kāore te kounga tirohanga e whakatauhia ana e te taumira anake. Ka tukuna e Dolby Vision te HDR urutau ake mā roto i ngā raraunga hihiri, te mahere oro matatau, me te tautoko tae me te rerekētanga whai kiko. Mā te ihirangi tika me ngā taputapu tautoko, ka rumakina ake te wheako mātakitaki, ka tūturu ake, ka pono ake hoki ki te tirohanga a te kaihanga.
Hei whakamutunga, ehara i te mea ko ngā whakaahua kanapa ake, ko ngā tae kanapa ake rānei te kaupapa o Dolby Vision, engari ko te āhua o te whakaatu tika ake a ngā pouaka whakaata hou i ngā taipitopito me ngā āhuatanga rerekē o te māramatanga—kia tata ake ai te āhua o te mata ki tā tātou tirohanga ki te ao tūturu.
