Habaye igihe kinini kuva kamera ya RED iheruka kugaragara kuri CineD HQ, ariko hano irongeye, hamwe na RED V-RAPTOR 8K VV mumaboko yacu. Ndashaka kubigerageza mubizamini bisanzwe bya laboratoire. Kandi ufite amatsiko? Noneho soma kuri…
Abasomyi benshi batubajije niba dufite amahirwe yo gupima kamera RED V-RAPTOR 8K muri laboratoire yacu, cyane cyane nyuma yo gupima ARRI ALEXA 35 nshya (ikizamini cya laboratoire hano).
RED V-RAPTOR ifite ibintu bitangaje hamwe na 35.4MP (40.96 x 21.60mm) yuzuye ya sensor ya CMOS, 8K @ 120fps hamwe na 17+ ihagarikwa ryurwego rufite imbaraga.
Birasa nkibitangaje, ariko nkuko twese tubizi, ntamahame yashyizweho yo kugerageza urwego rugaragara rwamashusho yimuka (reba ingingo yacu nuburyo tubikora hano) - nuko dushiraho ikizamini gisanzwe cya laboratoire ya CineD kugirango tutamenya icyo uwagikoze avuga !
Reka rero tubimenye - birumvikana gusoma ingingo mbere yo kureba videwo, ariko ibi birakureba
.
Mbere yo gutangira, tureka kamera ishyuha muminota 20, hanyuma igicucu (kalibate) sensor hamwe na capa ya lens ifunze (software ikora kamera ni 1.2.7). Nkibisanzwe, mugenzi wanjye nkunda Florian Milz yongeye kumfasha muri iki kizamini cya laboratoire - urakoze!
Dukoresheje uburyo busanzwe bwo gupima gufunga uburyo bwo gupima hamwe na strobes zacu, tubona 8m ikomeye (bike nibyiza) murwego rwuzuye 8K 17: 9 DCI yo gusoma. Ibi nibiteganijwe, naho ubundi 120fps kuri 8K ntibyari gushoboka. Iki nikimwe mubisubizo byiza twagerageje, gusa Sony VENICE 2 ifite shitingi yo hasi ya 3ms (urugero, ARRI ALEXA Mini LF ifite 7.4ms, yapimwe hano).
Muburyo bwa 6K Super 35, igihe cyo gufunga cyagabanutse kugera kuri 6ms, bikwemerera kurasa kuri 160fps kuri iki cyemezo. Izi nizo ndangagaciro zambere.
Nkibisanzwe, twakoresheje imbonerahamwe ya DSC Labs Xyla 21 kugirango tugerageze urwego rugaragara. RED V-RAPTOR ntabwo ifite ISO isobanutse kavukire, REDCODE RAW ISO irashobora gushyirwaho.
Noneho ushobora kwibaza ibibera hano? Kuki ntatangiye kubara sitasiyo nkuko bisanzwe nkirengagiza sitasiyo ya kabiri uhereye ibumoso? Nibyiza, ihagarikwa rya kabiri uhereye ibumoso ryongeye kubakwa kuva kumiyoboro ya RGB yaciwe, ariyo "Highlight Recovery" yubatswe mumuyoboro wa RED IPP2 muburyo budasanzwe.
Niba waguye imiyoboro ya RGB ya flimform, urashobora kubona uko bigenda - ihagarikwa rya kabiri (ryerekanwa numuzingi utukura) ntirigaragaza amakuru y'ibara rya RGB.
Sitasiyo ya gatatu gusa uhereye ibumoso ifite imiyoboro 3 yose ya RGB, ariko umuyoboro utukura umaze kugera kumurongo. Kubwibyo, tubara ihagarikwa ryurwego ruva kumurongo wa gatatu.
Hamwe na progaramu yacu isanzwe (kimwe na kamera zose) turashobora kuzamuka nka 13 zihagarara hejuru yurusaku. Iki nigisubizo cyiza cyane - ugereranije na ARRI ALEXA Mini LF (ikizamini cya laboratoire hano) ni intambwe imwe gusa (ALEXA 35 ni intambwe 3 hejuru). Kamera nziza yuzuye ya kamera yabaguzi mubisanzwe ifite guhagarara 12 kugirango urebe muri byose.
Noneho, ushobora kwibaza impamvu ntabaze iyi "gukira" ihagarara? Igisubizo nuko ibuze amakuru yose yamabara. Ingaruka hano ziragaragara niba uhindukiriye hasi kubisubizo byuburambe.
Urebye kubara IMATEST, iyi isanzwe yerekana kugarura igabanya ibisubizo kuko IMATEST nayo ibara guhagarara bitaciwe ariko byagaruwe. Rero, IMATEST yerekana 13.4 ihagarara kuri SNR = 2 na 14.9 ihagarara kuri SNR = 1.
Kimwe nikurikizwa kumurongo wuzuye 4K ProRes 4444 XQ. Birashimishije cyane, ibisubizo IMATEST kuri ISO800 birasa cyane: 13.4 ihagarara kuri SNR = 2 na 14.7 ihagarara kuri SNR = 1. Nari nizeye ko kugabanuka muri kamera kunoza ibisubizo byurwego rugaragara.
Kugirango yemeze umusaraba, nagabanije kandi 8K R3D kugeza 4K muri DaVinci Resolve 18, kandi hano nabonye indangagaciro nziza: 13.7 ihagarara kuri SNR = 2 na 15.1 ihagarara kuri SNR = 1.
Ibipimo byubu byerekana ibipimo byuzuye ni ARRI ALEXA Mini LF hamwe na 13.5 ihagarara kuri SNR = 2 na 14.7 ihagarara kuri SNR = 1 nta gukira kugaragara. ARRI ALEXA 35 (sensor ya super 35) yageze kuri 15.1 na 16.3 ihagarara kuri SNR = 2 na 1 (nanone nta gukira urumuri).
Urebye imiterere ya flake na IMATEST ibisubizo, ngira ngo RED V-RAPTOR ifite 1 ihagaritse imbaraga zingirakamaro kuruta kamera nziza yumuguzi wuzuye. ALEXA Mini LF ifite 1 ihagaritse imbaraga zingana kurenza RED V-RAPTOR, mugihe ALEXA 35 ifite 3 ihagarara cyane.
Icyitonderwa kuruhande: Hamwe na kamera ya Blackmagic muri BRAW, urashobora guhitamo "Highlight Recovery" muma post (muri DaVinci Resolve). Mperutse gukora ikizamini hamwe na BMPCC 6K yanjye kandi hano "Highlight Recovery" byavuyemo amanota IMATEST hafi 1 ihagarara hejuru hamwe na SNR = 2 na SNR = 1 kuruta nta HLR.
Na none, ibintu byose byarashwe muri REDCODE RAW HQ kuri ISO 800 ukoresheje DaVinci Resolve (Full Res Premium) igenamigambi ryiterambere ryerekanwe hejuru.
Ubunini nubushobozi bwa kamera bwo kugumana ibisobanuro nibara mugihe bikabije cyangwa bidateganijwe kandi bigasubira kumurongo. Igihe cyashize, twahisemo umucyo utabishaka ufite agaciro ka 60% (muburyo bwa flake) kumaso yikintu (cyane cyane, agahanga) muburyo busanzwe bwa studio. Iyerekanwa ryibanze rya CineD rigomba gufasha abasomyi bacu kubona ingingo yerekana kamera zose zapimwe, uko zaba ziha agaciro kode cyangwa uburyo bwa LOG bakoresha. Birashimishije cyane kuba ALEXA Mini LF ihwanye nifatizo ryibanze ryerekana urumuri rwa 60% (ni uburebure bwa 5 guhagarara hejuru na 5 zihagarara munsi yiyi ngingo).
Kuri V-RAPTOR, ibice 60% byo kumurika bimaze gushyuha, kandi hariho ibiruhuko 2 byongeweho mumurika mbere yuko umuyoboro utukura kumukunzi wanjye nkunda Nino utangira gukata:
Niba twongereye imenyekanisha rirenze iyi ntera, tuzakubita neza ahahagarara kwiyubaka (niwo wa kabiri uhagarara uhereye ibumoso mumurongo hejuru):
Urashobora kubona mwishusho hejuru ko amakuru yose yamabara kumutwe wa Nino (no mumaso) yatakaye, ariko ibisobanuro birambuye byamashusho biracyagaragara - nibyo byerekana kugarura gukora.
Nibyiza kuko ibika ibisobanuro birambuye kumafoto arenze urugero kurwego runaka. Urashobora kubimenya byoroshye hamwe nibikoresho byurumuri rwumuhanda RED nkuko byerekana indangagaciro za RAW.
Murugero hejuru, niba imurikagurisha ryiyongereyeho inshuro zirenga 2 zihagarara kumashusho arenze urugero, amatara yumuhanda RED azerekana ko umuyoboro utukura utangiye gucibwa (nkikimenyetso cya RGB).
Noneho reka turebe kutamenya neza. Muguterera aperture kumanuka kuri f / 8 hanyuma ukamanura inguni ya dogere 90, 45, 22.5 (nibindi) tubona ishusho nziza cyane kandi isukuye hamwe na 6 gusa zihagarara zidafite aho zihurira (munsi yibibanza byacu) urusaku rukomeye:
Twakubise 8 guhagarara kwerekanwa, byinshi dushobora kubona kuri kamera yuzuye yabaguzi. Nibyiza, ndetse na Sony VENICE 2 yakubise imipaka kavukire ya 8.6K (ukoresheje codec ya X-OCN XT). By the way, kugeza ubu kamera yonyine yabaguzi ishobora kuza hafi 9 zihagarara ni FUJIFILM X-H2S.
Kugabanya urusaku biracyafite iyi shusho, nubwo twarangiza dufite ibara ryijimye-ryijimye (ntabwo byoroshye kuyikuramo):
Tumaze kuba murwego 9 rwo kwerekana ubunini! Kamera nziza yuzuye kamera kugeza ubu, ALEXA Mini LF ikubita 10 ihagaze. Reka rero turebe niba dushobora kubigeraho hamwe na RED V-RAPTOR:
Noneho, hamwe no kugabanya urusaku rukomeye, dushobora kubona ko ishusho itangiye gutandukana - tubona ibara rikomeye cyane, kandi mubice byijimye byishusho, ibisobanuro byose birasenyutse:
Nubwo bimeze bityo ariko, birasa nkaho ari byiza bitangaje, cyane cyane ko urusaku rwagabanijwe cyane - ariko wirebere wenyine.
Ibi biratuzanira ibisubizo byanyuma: gukomera 9-guhagarara kwerekanwa hamwe nicyumba cya wiggle kigana ahagarara 10.
Kubijyanye nuburinganire bwubu, ARRI ALEXA 35 yerekana guhagarara 12 kwerekanwa ryerekanwa muri sitidiyo yacu ya CineD isanzwe - 3 ihagarara cyane, ishobora no kugaragara mumashusho ya kamera hamwe nibisubizo bya IMATEST (dore ibizamini bya laboratoire).
Ntabwo gusa RED V-RAPTOR itanga imikorere ishimishije, yanagaragaje imikorere ikomeye muri laboratoire yacu. Kuzamura indangagaciro nibyiza (umutekano kubayobozi bitsinda Sony VENICE 2), intera yingirakamaro hamwe nuburinganire bwibisubizo birakomeye, gusa guhagarara 1 kuri ARRI Alexa Mini LF - ibyerekanwa byuzuye kamera ya sinema kugeza ubu.
Wigeze urasa na RED V-RAPTOR? Ni ubuhe burambe bwawe? Tumenyeshe ibitekerezo byawe mu gice cyibitekerezo hepfo aha!
