Mahele 1: He aha ka HDR a me SDR?
Mahele 2: HDR vs. SDR Hoʻohālikelike
Mahele 3: ʻElua mau Manaʻo HDR Nui: Dolby Vision, HDR10 a me HDR10+
Mahele 4: Hiki i kāu hoʻonohonoho ke pāʻani i ka HDR?
Mahele 5: He mea pono ke hoʻonui i ka HDR?
Mahele 6: He aha inā ʻike ʻia ʻo 4K HDR a ʻāwili a holoi ʻia i ka wā e pāʻani ai?
Mahele 1: He aha ka HDR a me SDR?
SDR, a i ʻole Standard Dynamic Range, ʻo ia ka maʻamau o kēia manawa no nā hōʻike wikiō a me nā kiʻiʻoniʻoni.Hōʻike ʻo SDR i nā kiʻi a i ʻole wikiō me ka hoʻohana ʻana i kahi hōʻailona ʻāwili gamma maʻamau.Ua hoʻokumu ʻia ka pihi gamma maʻamau ma luna o nā palena o ka cathode ray tube (CRT) e hiki ai i ka luminance kiʻekiʻe o 100 cd/m2.
HDR, e kū ana no High Dynamic Range, he ʻano kiʻi kiʻi e hopu, hana, a hoʻopuka hou i nā ʻike ma ke ʻano e hiki ai i nā kikoʻī oua hoʻonui ʻia nā aka a me nā mea koʻikoʻi o kahi hiʻohiʻona.ʻOiai ua hoʻohana ʻia ʻo HDR i nā kiʻi kuʻuna i ka wā ma mua, ua hana ʻo ia i ka lele i nā smartphones, TV, monitors, a me nā mea hou aku.
Māhele 2: HDR vs. SDR Hoʻohālikelike: Nā ʻokoʻa ma waena o HDR a me SDR
Ua kaupalena ʻia ʻo SDR e kona hiki ke hōʻike wale i kahi hapa o ka laulā ikaika e hiki ai iā HDR ke hana.Mālama ʻo HDR i nā kikoʻī i nā hiʻohiʻona kahi e hiki ai i ka ratio like ʻole o ka monitor ke keʻakeʻa.ʻO SDR, ma kekahi ʻaoʻao, nele i kēia aptitude.Aia ka ʻokoʻa nui loa i ka laulā o ka gamut kala a me ka ʻōlinolino.ʻIke ʻoe, ʻae ʻo SDR i ka gamut kala o sRGB a me ka mālamalama mai 0 a 100nits.ʻOiai ʻo HDR ka laulā kala ʻoi aku ka nui a hiki i DCI - P3, ʻoi aku ka ʻoi aku o ka palena o luna o ka ʻālohilohi a me ka palena haʻahaʻa haʻahaʻa o ka mālamalama.Ma ka manawa like, hoʻomaikaʻi ʻo ia i ka maikaʻi o ke kiʻi holoʻokoʻa ma ke ʻano o ka ʻokoʻa, ka hoʻonā grayscale a me nā ʻāpana ʻē aʻe, e lawe mai ana i ka ʻike immersive i ka mea ʻike.
No ka maʻalahi, i ka hoʻohālikelike ʻana i ka HDR vs. SDR, ʻae ʻo HDR iā ʻoe e ʻike i nā kikoʻī hou aʻe a me ke kala i nā hiʻohiʻona me kahi laulā kiʻekiʻe.ʻO ia hoʻi, ʻoi aku ka mālamalama o HDR ma mua o SDR.Hāʻawi ka HDR iā ʻoe e ʻike i nā kikoʻī a me nā kala i nā hiʻohiʻona.ʻOi aku ka maikaʻi o HDR ma kēia mau ʻano:
◉ Mālamalama:Hāʻawi ka HDR i ka mālamalama o luna a hiki i 1000 nits a i lalo i lalo o 1 nit.
◉ gamut kala:Hoʻohana maʻamau ʻo HDR i ka P3, a me Rec.2020 color gamut.Hoʻohana ʻo SDR i ka Rec.709 ma ka laulā.
◉ Hōhonu kala:Hiki ke HDR i ka 8-bit, 10-bit a me 12-bit ka hohonu kala.ʻOiai ʻo SDR ka mea maʻamau i ka 8-bit, a he kakaikahi wale nō e hoʻohana i ka 10-bit.
Mahele 3: ʻElua mau Manaʻo HDR Nui: Dolby Vision, HDR10 a me HDR10+
ʻOiaʻiʻo, ʻaʻohe wehewehe hope o nā kūlana HDR.ʻElua mau kūlana koʻikoʻi i hoʻohana ʻia i kēia lā, ʻo Dolby Vision a me HDR10.Eia kekahi, aia kahi ʻano HDR10+ hou, e manaʻo ana e hoʻolauna i ka HDR dynamic i ka maʻamau HDR10 aʻo ka waiho ʻana i ka royalty-free.E hele mākou i nā ʻokoʻa ma waena o kēlā me kēia o nā ʻano HDR nui ʻelua ma lalo nei.
ʻIke Dolby
ʻO Dolby Vision kahi maʻamau HDR e koi ana i nā mākaʻikaʻi i hoʻolālā kūikawā ʻia me kahi chip hardware Dolby Vision.Aia ka uku mō'ī o Dolby Vision, ma kahi o $3 no kēlā me kēia TV.E like me HDR10, hoʻohana ʻo Dolby Vision i ka Rec.2020 wide color gamut, 1000 nits o ka ʻōlinolino, akā hoʻohana ʻo ia i ka hohonu o ka waihoʻoluʻu 12-bit a kākoʻo i ka hoʻolālā element data dynamic.
HDR10
ʻO HDR10 kahi maʻamau ākea, a ʻaʻole pono ʻoe e uku i nā royalties e hoʻohana ai.ʻO ka helu "10" ke kū nei no ka hohonu o ka kala 10bit.Ma waho aʻe o kēia, kākoʻo pū ʻo HDR10 i ka hoʻohana ʻana i ka gamut ākea Rec.2020, 1000 nits o ka mālamalama, a me ke ʻano hoʻoili ʻikepili static.
ʻO HDR10 ka maʻamau HDR maʻamau a kokoke i nā mea hana TV nui a me nā mea hoʻolako streaming, e like me Sony, Disney, 20th Century Fox, Warner Bros., Paramount, Universal, a me Netflix e hoʻohana i HDR10 e hana i nā disks ray 4K UHD Blu.Ma waho aʻe, kākoʻo nā mea like me Xbox One, PS4, Apple TV i HDR10.
HDR10 vs Dolby Vision - He aha ka ʻokoʻa?
ʻO HDR10 a me Dolby Vision ʻelua mau ʻano HDR nui.ʻO ka ʻokoʻa, ʻo HDR10 kahi maʻamau ākea a ʻaʻole pono, ʻoiai ʻo Dolby Vision e koi i ka laikini a me ka uku mai Dolby.
A ʻoiai ʻo Dolby Vision i kēia manawa hiki ke hana i kahi kiʻi maikaʻi aʻe, ʻaʻohe TV e hiki ke hoʻohana piha i ka mea e hāʻawi ai e kūʻē i ka HDR10.
Eia nō naʻe, hāʻawi ʻo Dolby Vision i kahi kiʻi kiʻi ʻoi aku ka maikaʻi, ma muli o kāna metadata dynamic.
HDR10+
E like me ka mea i ʻōlelo ʻia ma luna, aia kekahi ʻano HDR10+.ʻO HDR10+ kahi maʻamau HDR i hoʻonohonoho ʻia e Samsung no Dolby Vision, ʻo ia ka mea like me kahi ʻike evolutionary o HDR10.E like me Dolby Vision, kākoʻo ʻo HDR10+ i ka hoʻolālā element data dynamic, akā ʻo HDR10+ kahi maʻamau ākea, e manaʻo ana e loaʻa kahi ʻike leo-kiʻi maikaʻi ma ke kumu kūʻai haʻahaʻa.
I kēia manawa, ʻoi aku ka maikaʻi o ka HDR10, ʻoiai ʻo Dolby Vision ke koho uku.I ka manawa o kēia kākau ʻana, loaʻa wale ka ʻike DR10+ ma nā lawelawe streaming liʻiliʻi (me Amazon) a me nā disc, akā ʻoi aku ka nui o nā TV e hoʻomaka ana e kākoʻo i ka HDR10+.
Mahele 4: Hiki i kāu hoʻonohonoho ke pāʻani i ka HDR?
Ke loaʻa iā ʻoe kāu ʻike HDR, inā he wikiō HDR a i ʻole ka pāʻani HDR, pono ʻoe e hōʻoia i kāu hoʻonohonoho hiki ke hōʻike i kēlā ʻike HDR.
ʻO ka hana mua e hōʻoia i kāu kāleka kiʻi e kākoʻo i ka HDR.
Hiki ke hōʻike ʻia ka HDR ma luna o kahi HDMI 2.0 a me DisplayPort 1.3.Inā loaʻa i kāu GPU kekahi o kēia mau awa a laila hiki iā ia ke hōʻike i ka ʻike HDR.E like me ke kānāwai o ka manamana lima, loaʻa i nā Nvidia 9xx series GPU a me nā mea hou aʻe he port HDMI 2.0, e like me nā kāleka AMD āpau mai 2016 ma mua.
E like me ka hele ʻana o kāu hōʻike, pono ʻoe e hōʻoia i hiki iā ia ke kākoʻo i ka ʻike HDR.Pono e loaʻa i nā hōʻike hoʻohālikelike HDR ka liʻiliʻi o ka hoʻonā piha HD 1080p.ʻO nā huahana e like me Asus ROG Swift PG27UQ, Acer Predator X27, Alienware AW5520QF he mau hiʻohiʻona o nā mea nānā 4K me ke kākoʻo ʻike HDR10.Hoʻopili pū kēia mau mea nānā i ka pololei o ka waihoʻoluʻu i ka hoʻohālikelike i ka hoʻāʻo ʻana e hōʻoia i ka nānā ʻana o nā kiʻi ma ka pale i ka ʻoiaʻiʻo i ke ola e like me ka hiki.
Pehea e loaʻa ai nā ʻike HDR
Ma ke ʻano o ke kahe ʻana, kākoʻo ʻo Netflix a me Amazon Prime i ka HDR ma Windows 10. No nā ʻike HDR ʻē aʻe, ʻo Sony, Disney, 20th Century Fox, Warner Bros., Paramount, Universal, a me Netflix e hoʻohana i ka HDR10 e hana i nā ʻike 4K UHD Blu ray i loko. nā diski.A i ʻole hiki iā ʻoe ke hoʻopaʻa i kāu ʻike ponoʻī 4K HDR me ka mobile, GoPro, DJI, camcorder a me nā mea hou aku.
Mahele 5: He mea pono ke hoʻonui i ka HDR?
Inā ʻoe e noʻonoʻo nei i kahi lele i HDR, e noʻonoʻo paha ʻoe: He waiwai maikaʻi ʻo HDR?E haʻalele maoli anei ka ʻenehana High Dynamic Range?
ʻOiai ʻoiaʻiʻo, ʻaʻohe mea 100% maopopo, loaʻa i ka ʻenehana HDR ka waiwai i kona makemake.I kēia manawa, ua pili pono kāna ʻenehana i ka hoʻonā hoʻonā kiʻekiʻe kiʻekiʻe, i ʻike ʻia ʻo 4K.
No ka mea ke hāpai ʻia nei ʻo 4K e ka mākeke maʻamau me ka maʻalahi a me ka wikiwiki, ʻo ia ke kumu e hahai ai ʻo HDR i ka papa like i mua.Hiki iā mākou ke hoʻohālikelike i ka HDR vs. SDR i ka lā āpau akā inā maikaʻi a maikaʻi ʻole ʻo HDR iā ʻoe e iho i lalo i kāu ʻike pilikino.I kēia manawa, e ʻoluʻolu e ʻimi i ka laulā o ViewSonic o HDR-compatible ColorPro monitors a i ʻole luʻu hohonu i loko o ka honua o ka hoʻoponopono kala a me ka māka kala.
ʻO ka pōmaikaʻi no nā mea hoʻohana mua ma waho, ʻaʻole paʻakikī nā huahana HDR.Hoʻonui ʻia nā pono o HDR i ka pāʻani ma ka ʻae ʻana iā ʻoe e ʻike i nā kikoʻī hou aku i kāu mau pāʻani no ka manaʻo maoli.
He aha inā ʻike ʻia ka 4K HDR a holoi ʻia i ka wā e pāʻani ai?
Ke hoʻohālikelike ʻia me SDR (maʻamau dynamic range), hiki i ka HDR ke hoʻolilo i kāu wikiō i ʻoi aku ka moʻokalaleo a me ke ola ola me ka laulā o nā kala a me ka hohonu.Akā naʻe, ʻaʻohe mea kūpono.ʻOiai ke piʻi nei ka nui o ke kūʻai aku ʻana o nā hāmeʻa wikiō 4K HDR, ke hoʻohana mau ʻia nei nā TV SDR, nā mākaʻikaʻi, projectors, desktop a me nā kelepona.
No laila ke hele mai nei ka nīnau: ke nānā ʻoe i ka wikiō 4K HEVC HDR 10-bit ma ka hōʻike HDR ʻole i kākoʻo ʻia, e nalowale ka wikiō HDR i kona ʻano kala kumu a hoʻohaʻahaʻa i ka ʻōlinolino a me ka saturation.E lilo ke kiʻi wikiō holoʻokoʻa i hina.ʻO ia ka mea a mākou e kapa pinepine ai i ka kala holoi ʻia.
Ma ke kauoha e pāʻani i ka wikiō HDR 10-bit ma nā polokalamu SDR, pono ʻoe e hoʻololi i ka HDR i SDR mua i mea e hoʻopau ai i ka pilikia kala holoi.AEaseFab Video Converterʻo ia kekahi o nā ala maikaʻi loae hoʻohuli i nā wikiō 4K HDR i SDRma 4K/1080p, HEVC i ka H.264 me ka ʻole o ka nalo ʻana o ka maikaʻi ma ka ʻōlinolino, kala, ʻokoʻa a me nā mea hou aku.E aʻo hou e pili ana i kāna mau hiʻohiʻona nui:
◉ E ʻae i nā ʻano wikiō 4K HDR āpau, no hea mai lākou a me ke ʻano hoʻopāpā a lākou e hoʻohana ai.
◉ E hoʻohuli i nā wikiō 4K HDR i MP4, H.264, HEVC, MOV, AVI, FLV, iPhone, iPad, HDTV, Xbox, PS4 a me 420+ mau mea i hoʻonohonoho mua ʻia.
◉ Hoʻopiʻi i ka hoʻonā 4K i 1080p /720p a i ʻole HD kiʻekiʻe i ka 4K me ka maʻalahi me ka ʻole o ka nalowale o ka maikaʻi.
◉ ʻO ka wikiwiki hoʻololi wikiō wikiwiki loa & 100% maikaʻi i mālama ʻia me ke kākoʻo o ka wikiwiki ʻana o ka mīkini a me ka mīkini kiʻekiʻe.
