Zokonda Zapamwamba Zokweza pa YouTube

Kumvetsetsa Zofunikira pakukweza makanema pa YouTube

YouTube amathandiza zosiyanasiyana kanema akamagwiritsa, koma si onse akamagwiritsa analengedwa ofanana pankhani kweza khalidwe ndi processing liwiro. nsanja mwalamulo amalangiza MP4 owona ndi H.264 kanema codec ndi AAC Audio codec kwa mulingo woyenera kwambiri zotsatira. Kuphatikiza uku kumapereka kusanja kwabwino kwambiri kwamafayilo, mtundu, komanso kufananiza pazida zonse ndi asakatuli. Ngakhale YouTube amavomereza akamagwiritsa ngati MOV, avi, Wmv, flv, ndi WebM, Tikukweza mu akamagwiritsa zambiri kumabweretsa yaitali processing nthawi ndi kuthekera khalidwe kudzitsitsa pa YouTube a kutembenuka ndondomeko. Pulatifomu imasinthitsanso mavidiyo onse omwe adakwezedwa kuti akhale ndi malingaliro angapo komanso mawonekedwe oti azitha kutsitsa, koma kuyambira ndi mawonekedwe ovomerezeka amatsimikizira zotsatira zabwino kwambiri. Kumvetsetsa zofunikira zaukadaulo izi ndikofunikira kwa opanga zomwe akufuna kuti makanema awo aziwoneka mwaukadaulo ndikutsegula mwachangu kwa owonera.

• MP4 yokhala ndi H.264 codec ndi mtundu womwe YouTube amakonda
• Kukula kwakukulu kwa fayilo ndi 256GB kapena maola 12 muutali
• Mitengo yothandizidwa imaphatikizapo 24, 25, 30, 48, 50, ndi 60 FPS.

Makanema Oyenera Kwambiri ndi Makonda a Bitrate

Kusintha kwamavidiyo ndi bitrate kumagwirira ntchito limodzi kuti muwone momwe mumawonera komanso kukula kwa fayilo. Pazokweza za 1080p, YouTube imalimbikitsa bitrate pakati pa 8-12 Mbps pamitengo yokhazikika ndi 12-18 Mbps pazambiri zamafelemu (50/60fps). Ma bitrate okwera amasunga zambiri ndikuchepetsa kuphatikizika, koma amakhalanso ndi kukula kwamafayilo akulu komanso nthawi yayitali yokweza. Posankha chosankha, ganizirani gwero lanu la nkhani ndi omvera. Ngakhale 4K (2160p) imapereka kumveka kodabwitsa, imafunikira ma bitrate apamwamba kwambiri (35-45 Mbps) komanso nthawi yayitali yokonza. Opanga ambiri amapeza kuti 1080p imapereka malo okoma pakati pa zabwino ndi zochitika. Ndikofunikiranso kuti mufanane ndi zomwe mwakweza ndi momwe mumajambulira – kukweza mavidiyo otsika sikumapangitsa kuti zinthu zikhale bwino ndipo nthawi zambiri zimatulutsa zinthu zosafunikira. Kuti mupeze zotsatira zabwino kwambiri, gwiritsani ntchito encoding ya variable bitrate (VBR) osati constant bitrate (CBR). VBR imagawira ma bits ambiri pazithunzi zovuta zoyenda kapena tsatanetsatane kwinaku akugwiritsa ntchito pang’ono pazithunzi zosavuta, zomwe zimapangitsa kuti pakhale mawonekedwe abwinoko pamafayilo ang’onoang’ono.

Kukonzekera Kwamawu kwa Zotsatira Zaukadaulo

Mtundu wamawu nthawi zambiri umanyalanyazidwa koma umakhala ndi gawo lofunikira pakuchitapo kanthu kwa owonera komanso kusunga. YouTube imalimbikitsa AAC audio codec yokhala ndi chitsanzo cha 48kHz ndi bitrate ya 384 kbps pamawu a stereo. Zokonda izi zimapereka kutulutsa kwamawu komveka bwino ndikusunga mafayilo amawu oyenera. Pewani kugwiritsa ntchito ma bitrate otsika ngati 128 kbps, chifukwa amatha kuwonetsa zinthu zakale zomwe zimalepheretsa kuwonera. Kwa opanga zinthu omwe amagwiritsa ntchito nyimbo zingapo zomvera, monga nyimbo zosiyana ndi zojambulira mawu, ndikofunikira kulinganiza milingoyo musanayike. Kusintha kwamawu pa YouTube nthawi zina kumatha kukulitsa kusalinganika komwe kulipo, kupangitsa kusakanizika koyipa kuwonekera kwambiri. Onetsetsani kuti ma audio anu afika pachimake -6dB mpaka -3dB, kuchoka pamutu kuti YouTube ikonzere ndikupewa kupotoza. Kusasinthika kwa mawu muvidiyo yanu kumapangitsanso kuti owonera azitha kuwonera komanso kuchepetsa mwayi woti owonerera azisintha mawu awo pafupipafupi.

Frame Rate ndi Zosintha Zoyenda

Mtengo wamafelemu umakhudza kwambiri momwe mumawonera komanso kukula kwamafayilo omwe mumayika pa YouTube. Zinthu zokhazikika nthawi zambiri zimagwiritsa ntchito 24fps (cinematic), 25fps (PAL zigawo), kapena 30fps (muyezo wowulutsa), pomwe masewera ndi zoyenda kwambiri nthawi zambiri zimapindula ndi 60fps pakusewerera kosavuta. Mfundo yofunika kwambiri ndikufananiza kuchuluka kwa chimango chomwe mumayika ndi zomwe mumayambira – pewani kutembenuka kwamitengo ngati kuli kotheka chifukwa zitha kuyambitsa chibwibwi kapena kusayenda bwino. Kuti mudziwe zambiri, onetsetsani kuti bitrate yanu ndi yokwera mokwanira kuti muthe kudziwa zambiri zanthawi yayitali. Kanema wa 60fps amafunikira pafupifupi 1.5x the bitrate ya 30fps yofananira kuti asunge mulingo womwewo. Kuwonjezera apo, ganizirani mmene omvera anu amaonera komanso zipangizo zake. Ngakhale 60fps imapereka kuyenda kosalala, imafunikira bandwidth yochulukirapo komanso mphamvu yosinthira, zomwe sizingakhale zabwino kwa owonera pamalumikizidwe ocheperako kapena zida zakale. Mukasindikiza zinthu zolemetsa monga mavidiyo amasewera kapena masewera, gwiritsani ntchito zochunira zoyezera zoyenda mu encoder yanu. Ma aligorivimu apamwamba kwambiri oyerekeza zoyenda amatha kusintha kwambiri mawonekedwe a zinthu zomwe zikuyenda mwachangu komanso kuchepetsa zinthu zakale, ngakhale amawonjezera nthawi yosungira.

Kuganizira za Space Space ndi Dynamic Range

Malo amitundu ndi masinthidwe osinthika amakhudza momwe makanema anu amawonekera pazida ndi zowonera zosiyanasiyana. YouTube imathandizira ma standard dynamic range (SDR) ndi high dynamic range (HDR), koma owonera ambiri amawonerabe zowonetsera za SDR. Pazinthu za SDR, gwiritsani ntchito Rec. Malo amitundu 709 (omwe amadziwikanso kuti sRGB) okhala ndi malire (16-235) amitundu yotetezedwa pawayilesi yomwe imawonekera mosasinthasintha pazida zonse. Zomwe zili mu HDR zimapereka mtundu wokulirapo wa gamut ndi mtundu wowala koma zimafunikira magawo apadera a encoding ndi zida zowonera. Ngati mukukweza zomwe zili mu HDR, gwiritsani ntchito Rec. Malo amtundu wa 2020 okhala ndi PQ (Perceptual Quantizer) kapena HLG (Hybrid Log-Gamma) ntchito zosinthira. Komabe, onetsetsani kuti zomwe mwalemba zidajambulidwa kapena zidapangidwa mu HDR – kungolemba zomwe zili mu SDR chifukwa HDR kumapangitsa kuti mitundu ikhale yosasunthika komanso osawonera bwino. Kuti utoto ukhale wolondola, nthawi zonse gwirani ntchito m’malo oyenera ndikutumiza kunja pogwiritsa ntchito malo amtundu womwewo monga polojekiti yanu. Pewani kutembenuka kwa danga kodziwikiratu, chifukwa kumatha kusintha mitundu mosayembekezereka. Ngati simukutsimikiza za makonda amtundu, khalani ndi Rec. 709/sRGB, yomwe imatsimikizira kuseweredwa kosasintha pazida zambiri komanso momwe amawonera.

Kukonzekera Kwafayilo ndi Kukhathamiritsa Kwamafayilo

Kukonzekera koyenera kwa fayilo kumatha kuchepetsa kwambiri nthawi zotsitsa komanso kuchedwa kwa kukonza. Musanayambe kukweza, onetsetsani kuti fayilo yanu ya kanema imakonzedwa bwino komanso yokonzedwa bwino. Gwiritsani ntchito sikani yapang’onopang’ono m’malo mwa kanema womangika, chifukwa zolumikizira zimatha kuphatikizira zinthu zakale pamawonekedwe amakono. Kuphatikiza apo, ikani atomu ya moov kumayambiriro kwa mafayilo a MP4 (omwe amatchedwanso ‘web optimization’ kapena ‘kuyambira mwachangu’) kuti athe kutsitsa pang’onopang’ono komanso kusewera koyambirira mwachangu. Ganizirani za kulumikizidwa kwanu pa intaneti ndikuyika ndandanda pokonza mafayilo. Mafayilo akulu akulu a 4K amatha kutenga maola kuti akweze pamalumikizidwe ocheperako, ndipo mizere yokonza pa YouTube imatha kuchedwetsa nthawi yayitali kwambiri. Pazinthu zomwe sizingatenge nthawi, kutsitsa nthawi yomwe simunapiteko kwambiri (nthawi zambiri usiku kwambiri kapena m’mawa kwambiri m’dera lanu) nthawi zambiri kumabweretsa kukonza mwachangu. Muthanso kukweza makanema osatchulidwa kapena achinsinsi kuti mumalize kukonza musanawawonetse poyera. Kutchula mafayilo ndi ma metadata metadata nthawi zambiri samanyalanyazidwa koma mbali zofunika kwambiri pakukweza. Gwiritsani ntchito mayina ofotokozera ndikuwonetsetsa kuti mkonzi wanu wamakanema akutumiza metadata yoyera. Mapulogalamu ena osintha amaphatikiza ma metadata osafunikira omwe amatha kukulitsa kukula kwa mafayilo kapena kuyambitsa zovuta. Kukhala ndi chithunzithunzi chanu, mutu, mafotokozedwe, ndi ma tag okonzeka musanalowetse kumathandizanso kufalitsa.
