ProRes tekinoroji yekodhi yakagadziriswa neApple muna 2007 kune yavo Final Cut Pro software.Pakutanga, ProRes yaingowanikwa kumakomputa eMac chete.Pamwe chete nekukura rutsigiro nemamwe makamera evhidhiyo uye marekodhi, Apple yakaburitsa ProRes plug-ins yeAdobe Premiere Pro, Mushure meMigumo, uye Media Encoder, ichibvumira vashandisi veMicrosoft kugadzirisa mavhidhiyo muProRes fomati zvakare.
Zvakanakira kushandisa Apple ProRes codec mune post-kugadzirwa ndeiyi:
Yakaderedzwa basa remakomputa, nekuda kwekumanikidza kwemufananidzo
ProRes inodzvanya zvishoma yega yega yevhidhiyo yakatorwa, ichidzikisa vhidhiyo data.Nekudaro, komputa inokwanisa kugadzirisa iyo data data nekukurumidza panguva yekudonha uye kugadzirisa.
Mifananidzo yepamusoro
ProRes inoshandisa 10-bit encoding kuti iwane zviri nani ruzivo rwemavara neyakagwinya yekumanikidza mwero.ProRes inotsigirawo kutamba mavhidhiyo emhando yepamusoro mumhando dzakasiyana siyana.
Izvi zvinotevera zvinounza marudzi akasiyana eApple ProRes mafomati.Kuti uwane ruzivo nezve "kudzika kwemavara" uye "chroma sampling", ndapota tarisa zvinyorwa zvedu zvakapfuura-Chii chinonzi 8-bit, 10-bit, 12-bit, 4:4:4, 4:2:2 uye 4:2:0
Apple ProRes 4444 XQ: Iyo yemhando yepamusoro-soro ProRes vhezheni inotsigira 4:4:4:4 mifananidzo masosi (kusanganisira alpha chiteshi) ine yakakwirira kwazvo data data kuchengetedza ruzivo mumhando yepamusoro-soro-emhando yemifananidzo inogadzirwa neanhasi-yemhando yepamusoro dhijitari. mifananidzo sensors.Apple ProRes 4444 XQ inochengetedza maseru ane simba akati wandei kupfuura simba reRec.709 mifananidzo-kunyangwe inopesana nekuomarara kweakanyanya kuona maitiro ekugadzirisa, umo matema-chiyero matema kana mapeji akatambanudzwa zvakanyanya.Seyakajairwa Apple ProRes 4444, iyi codec inotsigira anosvika gumi nemaviri mabhiti pachiteshi chemufananidzo uye gumi nematanhatu mabhiti ealpha chiteshi.Apple ProRes 4444 XQ inoratidzira chiyero che data chakanangana ne500 Mbps ye4:4:4 masosi pa1920 x 1080 uye 29.97 fps.

Apple ProRes 422 HQ: Iyo yepamusoro data-reti vhezheni yeApple ProRes 422 inochengetedza mhando yekuona padanho repamusoro seApple ProRes 4444, asi ye4: 2: 2 masosi emifananidzo.Nekugamuchirwa kwakapararira kwese kwevhidhiyo post-yekugadzira indasitiri, Apple ProRes 422 HQ inopa inooneka isingarasikirwe kuchengetedzwa kweyepamusoro-mhando nyanzvi HD vhidhiyo iyo imwe-link HD-SDI chiratidzo chinogona kutakura.Iyi kodeki inotsigira kuzara-hupamhi, 4:2:2 vhidhiyo masosi pa10-bit pixel kudzika uku ichiramba ichiona isingarasikike kuburikidza nezvizvarwa zvakawanda zvekudhirodha nekukodha zvakare.Apple ProRes 422 HQ's target data rate ingangoita 220 Mbps pa1920 x 1080 uye 29.97 fps.
Apple ProRes 422: Iyo yepamusoro-yemhando yakadzvanywa codec inopa zvingangoita zvese zvakanaka zveApple ProRes 422 HQ, asi pa66 muzana yeyero yedata kune zvirinani multistream uye chaiyo-nguva editing kuita.Apple ProRes 422's tarisiro yechiyero ingangoita 147 Mbps pa1920 x 1080 uye 29.97 fps.
Apple ProRes 422 LT: Iyo yakanyanya kudzvanywa codec kupfuura
Apple ProRes 422, ine ingangoita makumi manomwe muzana yehuwandu hwe data uye
30 muzana madiki mafaira saizi.Iyi codec yakanakira nharaunda uko kuchengetedza huwandu uye chiyero chedata zvakanyanya kukosha.Apple ProRes 422 LT's target data rate ingangoita 102 Mbps pa1920 x 1080 uye 29.97 fps.
Apple ProRes 422 Proxy: Iyo yakatonyanya kudzvanywa kodheki kupfuura Apple ProRes 422 LT, yakagadzirirwa kushandiswa mukufambiswa kwemhepo kunoda yakaderera data mareti asi Yakazara HD vhidhiyo.Apple ProRes 422 Proxy's target data rate ingangoita 45 Mbps pa1920 x 1080 uye 29.97 fps.
Chati iri pazasi inoratidza kuti Apple ProRes' data rate inofananidzwa sei neiyo uncompressed Full HD resolution (1920 x 1080) 4:4:4 12-bit uye 4:2:2 10-bit mifananidzo inoteedzana pa29.97 fps.Zvinoenderana nechati, kunyange kutora epamusoro-mhando ProRes mafomati- Apple ProRes 4444 XQ uye Apple ProRes 4444, inopa yakanyanya kuderera kushandiswa kwedata pane iyo yemifananidzo isina kuomeswa.
