Hoʻomaopopo i ka Mana Ma hope o Apple ProRes

ʻO ProRes kahi ʻenehana codec i hoʻomohala ʻia e Apple ma 2007 no kā lākou polokalamu Final Cut Pro.I ka wā mua, loaʻa wale ʻo ProRes no nā kamepiula Mac.Me ka ulu ʻana o ke kākoʻo e nā kiʻi wikiō a me nā mea hoʻopaʻa leo, ua hoʻokuʻu ʻo Apple i nā plug-in ProRes no Adobe Premiere Pro, After Effects, a me Media Encoder, e ʻae ana i nā mea hoʻohana Microsoft e hoʻoponopono i nā wikiō ma ProRes format pū kekahi.

ʻO nā mea maikaʻi o ka hoʻohana ʻana i ka codec Apple ProRes ma hope o ka hana ʻana:

Hoʻemi ʻia ka hana kamepiula, mahalo i ka hoʻoemi kiʻi

Hoʻopili iki ʻo ProRes i kēlā me kēia kiʻi o ka wikiō i hopu ʻia, e hōʻemi ana i ka ʻikepili wikiō.Ma ka huli ʻana, hiki i ke kamepiula ke hana wikiwiki i ka ʻikepili wikiō i ka wā decompression a me ka hoʻoponopono.

Nā kiʻi kūlana kiʻekiʻe

Hoʻohana ʻo ProRes i ka 10-bit encoding no ka loaʻa ʻana o ka ʻike kala ʻoi aku ka maikaʻi me ka helu hoʻopiʻi kūpono.Kākoʻo pū ʻo ProRes i ka pāʻani ʻana i nā wikiō kiʻekiʻe ma nā ʻano like ʻole.
Hōʻike ʻia nā ʻano like ʻole o nā ʻano Apple ProRes.No ka ʻike e pili ana i ka "hohonu kala" a me "ka hoʻohālike chroma", e ʻoluʻolu e nānā i kā mākou ʻatikala mua-He aha nā 8-bit, 10-bit, 12-bit, 4:4:4, 4:2:2 a me 4:2:0

Apple ProRes 4444 XQ: Kākoʻo ka mana ProRes kiʻekiʻe loa i nā kumu kiʻi kiʻi 4:4:4:4 (me nā ala alpha) me ka helu kiʻekiʻe loa e mālama i nā kikoʻī i nā kiʻi kiʻi kiʻekiʻe kiʻekiʻe i hana ʻia e nā kiʻi kiʻi kiʻekiʻe loa o kēia lā. nā mea ʻike kiʻi.Mālama ʻo Apple ProRes 4444 XQ i nā pae hoʻolalelale i ʻoi aku ka nui ma mua o ka laulā ikaika o Rec.709 kiʻi—ʻoiai e kūʻē i ka paʻakikī o ka hoʻoponopono ʻana i nā hopena hiʻohiʻona koʻikoʻi, kahi i hoʻonui nui ʻia ai nā ʻeleʻele a i ʻole nā ​​mea koʻikoʻi.E like me Apple ProRes 4444 maʻamau, kākoʻo kēia codec a hiki i ka 12 bits ma ke kahawai kiʻi a me 16 bits no ke kahawai alpha.Hōʻike ʻia ʻo Apple ProRes 4444 XQ i ka helu ʻikepili pahuhopu ma kahi o 500 Mbps no nā kumu 4:4:4 ma 1920 x 1080 a me 29.97 fps.

Apple ProRes 4444: He mana ProRes kiʻekiʻe loa no nā kumu kiʻi 4:4:4:4 (me nā ala alpha).Hōʻike kēia codec i ka hoʻonā piha, mastering-quality 4: 4: 4: 4 RGBA waihoʻoluʻu a me ka hilinaʻi ʻike i ʻike ʻole ʻia mai ka mea kumu.ʻO Apple ProRes 4444 kahi hopena kiʻekiʻe no ka mālama ʻana a me ka hoʻololi ʻana i nā kiʻi neʻe a me nā composites, me ka hoʻokō maikaʻi loa a me kahi kahawai alpha nalowale makemakika a hiki i 16 mau bits.He haʻahaʻa haʻahaʻa loa kēia codec i hoʻohālikelike ʻia me ka 4:4:4 HD ʻole i hoʻopaʻa ʻia, me ka helu ʻikepili pahuhopu ma kahi o 330 Mbps no nā kumu 4:4:4 ma 1920 x 1080 a me 29.97 fps.Hāʻawi pū ia i ka hoʻopili pololei ʻana a me ka decoding o nā ʻano kikoʻī RGB a me Y'CBCR pixel.

ʻO Apple ProRes 422 HQ: ʻO kahi mana ʻikepili kiʻekiʻe o Apple ProRes 422 e mālama i ka maikaʻi ʻike ma ka pae kiʻekiʻe like me Apple ProRes 4444, akā no nā kumu kiʻi 4:2:2.Me ka hoʻohana nui ʻana ma waena o ka ʻoihana wikiō hope-production, hāʻawi ʻo Apple ProRes 422 HQ i ka mālama ʻana me ka ʻike ʻole ʻia o ka wikiō HD ʻoihana kiʻekiʻe loa i hiki i kahi hōʻailona HD-SDI loulou hoʻokahi ke lawe.Kākoʻo kēia codec i ka laulā piha, 4:2:2 kumu wikiō ma 10-bit pixel hohonu ʻoiai e waiho ana me ka ʻike ʻole ʻia ma o nā hanauna he nui o ka decoding a me ka hoʻopili hou ʻana.ʻO Apple ProRes 422 HQ ka helu helu ʻikepili ma kahi o 220 Mbps ma 1920 x 1080 a me 29.97 fps.

Apple ProRes 422: ʻO kahi codec hoʻopili kiʻekiʻe kiʻekiʻe e hāʻawi kokoke ana i nā pono āpau o Apple ProRes 422 HQ, akā ma ka 66 pakeneka o ka helu ʻikepili no ka hana hoʻoponopono multistream maikaʻi aʻe.ʻO Apple ProRes 422 ka helu kuhi ma kahi o 147 Mbps ma 1920 x 1080 a me 29.97 fps.

Apple ProRes 422 LT: ʻO kahi codec i hoʻopaʻa nui ʻia ma mua o

ʻO Apple ProRes 422, me ka 70 pakeneka o ka helu ʻikepili a

30 ka nui o ka waihona liʻiliʻi.He kūpono kēia codec no nā kaiapuni kahi i koʻikoʻi ai ka mana mālama a me ka helu ʻikepili.ʻO Apple ProRes 422 LT ka helu helu ʻikepili ma kahi o 102 Mbps ma 1920 x 1080 a me 29.97 fps.

ʻO Apple ProRes 422 Proxy: ʻO kahi codec i hoʻopaʻa ʻia ʻoi aku ka maikaʻi ma mua o Apple ProRes 422 LT, i manaʻo ʻia no ka hoʻohana ʻana i nā kahe hana waho e koi ana i nā helu ʻikepili haʻahaʻa akā ke wikiō Full HD.ʻO Apple ProRes 422 Proxy ka helu helu ʻikepili ma kahi o 45 Mbps ma 1920 x 1080 a me 29.97 fps.
Hōʻike ka pakuhi ma lalo i ke ʻano o ka helu ʻikepili Apple ProRes i hoʻohālikelike ʻia me ka hoʻonā piha HD piha ʻole (1920 x 1080) 4:4:4 12-bit a me 4:2:2 10-bit sequences kiʻi ma 29.97 fps.Wahi a ka pakuhi, ʻo ka hoʻohana ʻana i nā format ProRes kiʻekiʻe loa- ʻO Apple ProRes 4444 XQ a me Apple ProRes 4444, hāʻawi i ka hoʻohana haʻahaʻa haʻahaʻa ma mua o nā kiʻi i hoʻopaʻa ʻole ʻia.
