Papita nthawi yayitali kuchokera pomwe kamera yomaliza YOFIIRA idawonekera ku CineD HQ, koma nayinso, ndi RED V-RAPTOR 8K VV m'manja mwathu. Ndikufuna kuyesa m'mayeso athu a labotale. Komanso chidwi? Kenako werengani…
Owerenga ambiri atifunsa ngati tili ndi mwayi woyesa kamera ya RED V-RAPTOR 8K mu labu yathu, makamaka titayesa ARRI ALEXA 35 yatsopano (mayeso a labu apa).
RED V-RAPTOR ili ndi mawonekedwe odabwitsa okhala ndi 35.4MP (40.96 x 21.60mm) sensa yathunthu ya CMOS, 8K@120fps komanso malo oti 17+ oyimitsira osiyanasiyana.
Zikumveka zodabwitsa, koma monga momwe tonse tikudziwira, palibe muyezo wokhazikitsidwa woyesera mitundu yosunthika ya zithunzi zosuntha (onani nkhani yathu ndi momwe timachitira apa) - kotero tidapanga mayeso a labotale a CineD kuti tisadziwe zomwe wopanga akunena. !
Chifukwa chake, tiyeni tiganizire - ndizomveka kuwerenga nkhaniyi musanawone kanema, koma izi zili ndi inu.
.
Tisanayambe, timalola kamera kutentha kwa mphindi 20, kenako mthunzi (kuwongolera) kachipangizo ndi kapu ya lens yotsekedwa (kamera yamakono yamakono ndi 1.2.7). Monga mwachizolowezi, mnzanga wokondedwa Florian Milz adandithandizanso ndi mayeso a labu - zikomo!
Pogwiritsa ntchito njira yathu yoyezera zotsekera zotsekera ndi ma strobes, timapeza 8ms yolimba (yochepa ndi yabwino) muzithunzi zonse za 8K 17:9 DCI. Izi ziyenera kuyembekezera, apo ayi 120fps pa 8K sizikanatheka. Ichi ndi chimodzi mwazotsatira zabwino kwambiri zomwe taziyesa, ndi Sony VENICE 2 yokha yomwe ili ndi chotseka chotsika cha 3ms (mwachitsanzo, ARRI ALEXA Mini LF ili ndi 7.4ms, yoyesedwa apa).
Mu 6K Super 35 mode, nthawi yotseka yotsekera imachepetsedwa kufika 6ms, kukulolani kuwombera pa 160fps pa chisankho ichi. Izi ndizofunika kwambiri.
Monga mwachizolowezi, tidagwiritsa ntchito tchati cha DSC Labs Xyla 21 kuyesa kuchuluka kwamphamvu. RED V-RAPTOR ilibe ISO yodziwika bwino, REDCODE RAW ISO ikhoza kukhazikitsidwa.
Tsopano mwina mukudabwa kuti chikuchitika ndi chiyani apa? Bwanji sindinayambe kuwerengera masiteshoni monga mwanthawi zonse ndikunyalanyaza siteshoni yachiwiri kuchokera kumanzere? Chabwino, kuyimitsidwa kwachiwiri kuchokera kumanzere kumamangidwanso kuchokera kumayendedwe odulidwa a RGB, omwe ndi "Highlight Recovery" yomangidwa mupaipi ya RED IPP2 mwachisawawa.
Ngati mukulitsa njira za RGB za mawonekedwe ozungulira, mutha kuwona zomwe zimachitika - kuyimitsidwa kwachiwiri (kowonetsedwa ndi bwalo lofiira) sikuwonetsa zambiri zamtundu wa RGB.
Ndi siteshoni yachitatu yokha kuchokera kumanzere yomwe ili ndi mayendedwe onse a 3 RGB, koma njira yofiyira ili kale pachimake. Chifukwa chake, timawerengera maimidwe amitundu yosiyanasiyana kuchokera pagawo lachitatu.
Chifukwa chake ndi njira yathu yokhazikika (monga makamera onse) titha kupita ku malo pafupifupi 13 pamwamba pa phokoso. Izi ndi zotsatira zabwino kwambiri - poyerekeza ndi ARRI ALEXA Mini LF (mayeso a labu apa) ndi sitepe imodzi yokha (ALEXA 35 ndi masitepe 3 apamwamba). Makamera abwino kwambiri ogula zonse amakhala ndi malo pafupifupi 12 kuti awone chilichonse.
Tsopano, mwina mukuganiza kuti chifukwa chiyani sindinawerenge izi "kuchira" kuyima? Yankho ndiloti ilibe chidziwitso cha mtundu wonse. Zomwe zili pano ndizodziwikiratu ngati mupita ku zotsatira za latitude.
Kuyang'ana mawerengedwe a IMATEST, kuchira kokhazikika kumeneku kumasokoneza zotsatira chifukwa IMATEST imawerengeranso zoyima zomwe sizinadulidwe koma zobwezeretsedwa. Chifukwa chake, IMATEST ikuwonetsa kuyima kwa 13.4 pa SNR = 2 ndi 14.9 kuyima pa SNR = 1.
Zomwezo zikugwiranso ntchito pazithunzi zonse za 4K ProRes 4444 XQ. Chochititsa chidwi kwambiri, zotsatira za IMATEST pa ISO800 ndizofanana kwambiri: 13.4 imayima pa SNR = 2 ndi 14.7 imayima pa SNR = 1. Ndinkayembekezera kutsika kwa kamera kupititsa patsogolo zotsatira zamitundu yosiyanasiyana.
Kuti nditsimikizire pamtanda, ndidatsitsanso 8K R3D mpaka 4K mu DaVinci Resolve 18, ndipo apa ndidapeza zabwino kwambiri: 13.7 imayima pa SNR = 2 ndi kuyima 15.1 pa SNR=1.
Chiyembekezo chathu chapano chamitundu yonse yosinthika ndi ARRI ALEXA Mini LF yokhala ndi maimidwe 13.5 pa SNR=2 ndi kuyima 14.7 pa SNR=1 popanda kuchira. ARRI ALEXA 35 (sensa ya Super 35) inapeza 15.1 ndi 16.3 kuyima pa SNR = 2 ndi 1 motsatira (kachiwiri popanda kuchira).
Kuyang'ana ma waveform ndi zotsatira za IMATEST, ndikuganiza kuti RED V-RAPTOR ili ndi 1 yoyimitsa kwambiri kuposa makamera abwino kwambiri ogula. ALEXA Mini LF ili ndi 1 yoyimitsa kwambiri kusiyana ndi RED V-RAPTOR, pamene ALEXA 35 ili ndi 3 maimidwe ambiri.
Cholemba chakumbali: Ndi makamera a Blackmagic mu BRAW, mutha kusankha njira ya "Highlight Recovery" positi (mu DaVinci Resolve). Posachedwapa ndidayesa mayeso ndi BMPCC 6K yanga ndipo apa njira ya "Highlight Recovery" idapangitsa kuti mupambane pa IMATEST pafupi ndi malo amodzi okwera ndi SNR=2 ndi SNR=1 kuposa opanda HLR.
Apanso, zonse zidawomberedwa mu REDCODE RAW HQ ku ISO 800 pogwiritsa ntchito zosintha za DaVinci Resolve (Full Res Premium) zomwe zawonetsedwa pamwambapa.
Latitude ndi kuthekera kwa kamera kusunga tsatanetsatane ndi mtundu ikakhala yowonekera kwambiri kapena yocheperako ndikubwerera kumalo oyambira. Nthawi ina m'mbuyomu, tidasankha kuwala kopitilira muyeso kwa 60% (mu mawonekedwe a mafunde) pankhope ya chinthu (kwenikweni, pamphumi) mu studio yokhazikika. Kuwonetsedwa kwa CineD kofunikira kumeneku kuyenera kuthandiza owerenga athu kuti azitha kudziwa makamera onse omwe ayesedwa, ziribe kanthu momwe amagawira ma code kapena momwe amagwiritsira ntchito LOG. Ndizosangalatsa kwambiri kuti ALEXA Mini LF ndi yofananira pazomwe zimayambira pamtengo wowala wa 60% (ndi latitude 5 kuyima pamwamba ndi kuyima 5 pansipa).
Kwa V-RAPTOR, mawonekedwe owoneka bwino a 60% ndiwotentha kale, ndipo pali kuyimitsidwa kowonjezera 2 pazowunikira kwambiri njira yofiyira pamphumi ya mnzanga Nino ikuyamba kudumpha:
Ngati tiwonjezera kuwonekera kupitirira mulingo uwu, tidzagunda ndendende malo oyimitsiranso (omwe ndi kuyimitsidwa kwachiwiri kuchokera kumanzere kwa mawonekedwe apamwamba pamwambapa):
Mutha kuwona pachithunzi pamwambapa kuti zidziwitso zonse zamitundu pamphumi ya Nino (ndi nkhope) zatayika, koma tsatanetsatane wazithunzi zikuwonekerabe - ndizomwe zimawonetsa kuchira.
Izi ndizabwino chifukwa zimasunga zambiri pazithunzi zowoneka bwino kwambiri. Mutha kuzizindikira mosavuta ndi zida zowunikira za RED traffic pomwe zimawonetsa RAW sensor values.
Muchitsanzo chomwe chili pamwambapa, ngati chiwonetserochi chikuwonjezedwa ndi maimidwe opitilira 2 a chithunzi chowonekera kwambiri, magetsi amtundu wa RED awonetsa kuti njira yofiyira ikuyamba kudulidwa (monga chizindikiro cha RGB).
Tsopano tiyeni tione underexposure. Pogwetsa kabowo mpaka f/8 kenako ndikutsitsa chotsekera mpaka 90, 45, 22.5 madigiri (ndi zina) timapeza chithunzi chabwino kwambiri komanso choyera chokhala ndi kuyimitsidwa 6 kokha (pansipa gawo lathu) phokoso lalikulu:
Tidagunda ma stop 8 a exposure latitude, zambiri zomwe titha kuzipeza kuchokera ku kamera yamtundu wathunthu. Chabwino, ngakhale Sony VENICE 2 idagunda malire a 8.6K (pogwiritsa ntchito X-OCN XT codec). Mwa njira, mpaka pano kamera yokhayo yogula yomwe ingabwere pafupi ndi 9 maimidwe ndi FUJIFILM X-H2S.
Kuchepetsa phokoso kumasungabe chithunzichi, ngakhale timakhala ndi utoto wolimba kwambiri wabulauni-pinki (omwe siwosavuta kuchotsa):
Tili kale pamiyezo 9 ya exposure latitude! Kamera yabwino kwambiri yonse mpaka pano, ALEXA Mini LF imagunda maimidwe 10 olimba. Chifukwa chake tiwone ngati tingakwaniritse izi ndi RED V-RAPTOR:
Tsopano, ndi kuchepetsa phokoso lamphamvu, tikhoza kuona kuti chithunzicho chikuyamba kugwa - timapeza mtundu wamphamvu kwambiri, ndipo m'madera amdima a chithunzicho, zonse zawonongeka:
Komabe, zikuwonekabe zabwino modabwitsa, makamaka popeza phokoso limagawidwa mochepa kwambiri - koma dziweruzire nokha.
Izi zikutifikitsa kumapeto: mawonekedwe olimba a 9-stop exposure latitude yokhala ndi chipinda chogwedezeka kupita ku malo 10.
Ponena za kalozera wamakono, ARRI ALEXA 35 ikuwonetsa kuyimitsidwa kwa 12 kwa mawonekedwe owonekera mumsewu wathu wamba wa CineD studio - 3 imayima zambiri, zomwe zitha kuwonekanso pamawonekedwe a kamera ndi zotsatira za IMATEST (awa ndi mayeso a labu).
Sikuti RED V-RAPTOR imangopereka magwiridwe antchito, yawonetsanso magwiridwe antchito apamwamba mu labu yathu. Miyezo yotsekera ndi yabwino kwambiri (otetezeka kwa mtsogoleri wa gulu Sony VENICE 2), mawonekedwe osinthika komanso mawonekedwe owoneka bwino ndi amphamvu, kuyimitsidwa kamodzi kokha kuchokera ku ARRI Alexa Mini LF - kamera yathu yamakanema yamawonekedwe athunthu mpaka pano.
Kodi mudawomberapo ndi RED V-RAPTOR? Kodi mwakumana ndi zotani? Tiuzeni malingaliro anu mu gawo la ndemanga pansipa!
