MOV kuya AV1 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi MOV ku AV1 ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Layisha phezulu ifayela lakho MOV futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless AV1 output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / umgangatho ophezulu). I-codec ikhethiwe ukufana ne-AV1 container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. I-MOV ivame ukuthwala i-H.264 noma i-HEVC yokudlulisa, noma i-ProRes uma iyi-editor master, kanye ne-AAC noma umsindo we-PCM ongacindezelwa. AV1 yi-codec, hhayi isiqoqi — i-bitstream ihamba ngaphakathi MP4 noma WebM, ixhunywe ne-Opus noma i-AAC umsindo.

Ingabe i-AV1 izodlala kwi-browser uma i-MOV ingadlalanga?

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I MOV efakwe kwikhasi lewebhu ibonisa umdlali okhubazekile noma icindezela ukulayisha, ngoba iziphequluli azikho izikhombisi ezizo. AV1 idlala ngaphakathi ngengxenye yevidiyo ye-HTML5 engavamile ngaphandle kweplugin noma kusetshenziswa okungaphandle. AV1 inikeza cishe 30% engcono ucindezelo kuna H.264 esezingeni elifanayo futhi ithatha akukho izinkokhelo izitifiketi, okuyinto kungani YouTube ne Netflix push it.

Ingabe i-AV1 izodlala ngokulula ku-smartphone noma ku-TV?

Kungenzeka ukuthi ayisebenzi. MOV i-decoded yi-silicon ekhethekile kumafoni, ama-tablets nama-TV, ngakho-ke idlala ngaphandle kokucindezela ibhethri. AV1 ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, MOV luyi-container ephephile yokuhlala kuyo. AV1 encoding ihamba kancane, futhi amathuluzi decoders kuphela wavela kumafoni namahlaya kusukela mayelana 2020 kuqala - amadivayisi adala buyela amandla-ukudla isofthiwe decoding.

Ingabe AV1 iyibhokisi noma i-codec, futhi ngabe lokhu kushintsha lokho engikutholayo emuva?

Ishintsha ukuthi yini ongayilindele kuhele lwesingeniso. Ingxenye eyodwa yokuguqulwa ibizwa ngokuthi ukungenisa ngaphandle, hhayi ukupakisha, ngakho lokho okubuyayo ukuthi i-bitstream ngaphakathi kwebhokisi elifanele kakhulu — ngokuvamile MP4 noma MKV. Uhlelo lubonisa ibhokisi; i-codec yilokho okusho ubukhulu befayela futhi lapho izodlala khona.

Yini i-codec yevidiyo i AV1 isebenzisa?

Kuxhomekeka ku AV1 isiqoqi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhuleki, nama-Smart TVs. MKV iphutha ku-H.265 / HEVC ukuze kufinyelelwe isigamu sesayizi yefayela ngekhwalithi elinganayo. WebM iphutha ku-VP9. Izinketho ezithuthukisiwe zibonisa ukhetho lwe-codec olucacile uma ufuna ukucima. AV1 yi-video codec engekho emthethweni ye-Alliance for Open Media ekhishwa ngo-2018 njengengxenye yokulandela i-VP9.

Ingabe umsindo wami uzohlala ukhona MOV kuya ku AV1?

Yebo. Uma MOV ne AV1 bebelana nge-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka uphawu — okufanayo. Uma ama-codecs ahluka, umsindo uguqulwa ku-AAC / Opus / Vorbis ngokuya ngoAV1 ibhokisi lokusekela. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula MOV ku AV1?

Ngokungajwayelekile yebo — i-24fps MOV ihlala i-24fps ku-AV1; i-60fps MOV ihlala i-60fps. Uma ufuna ukuguqula isilinganiso (isibonelo, i-interlaced 29.97 → progressive 30, noma i-60 → 30 uku-upload amalimi), isinqumo se-framerate siphatha 3:2 uku-pulldown, deinterlacing, ne-frame-blending ku-code pass efanayo.

Ingabe ubukhulu befayela bushintsha kanjani kusuka ku MOV kuya ku AV1?

Same-codec re-mux (MOV H.264 → AV1 H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 kufaka ihele ngengxenye ngaleyo khwalithi yokubuka efanayo; VP9 ifana kakhulu; AV1 ihlukanisa ezinye 20-30% kodwa ihamba kancane ukukopela.

Ingabe ihele AV1 lizodlala ku-iPhone, Android, ne-Smart TVs?

MP4 / H.264 idlala ngokusemthethweni kuwo wonke amadivayisi amanje. MOV / H.264 idlala kumadivayisi we-Apple namanye ama-TV kodwa ahlala e-Android edlule. I-MKV idinga i-VLC ku-iOS. I-WebM iyisiphequluli sokuqala. Izinketho ezithuthukisiwe zifaka "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-AV1 codec / ibhokisi eliphephile kakhulu lenjongo yakho.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-MOV ividiyo yehora elilodwa ibe yi-AV1?

I-same-codec re-mux ifinyelela ngokushesha — 30 kuya ku-60 imizuzwana yefayela lehora elilodwa. I-codec ephelele iphinde ikhodeke isebenza ngokuyisisekelo 0.3-0.7x isikhathi somthombo ku-GPU yethu, ngakho-ke i-1-hour MOV → AV1 iphele ngemizuzu engu-18-40 ngokuya ngesinqumo ne-codec ethengiswayo.

Yini isixazululo esiphezulu esixhaswe yi MOV kuya ku AV1?

Kuze ku-8K (7680×4320) kuma-premium plans. Ukuguquka okumahhala kufinyelela ku-4K (3840×2160) ngobukhulu befayela ngalinye. I-HDR metadata (HDR10, HDR10+, Dolby Vision uma ikhona) idluliselwa lapho ama-MOV ne-AV1 amabhokisi axhasa khona.

Ingabe i-MOV yami yevidiyo ifihlakele ngesikhathi sokuguqulwa ku-AV1?

Yebo. Amafayela wevidiyo alayishwe phezulu aphathwa emisebenzini ehlukanisiwe, angeke abonelwe umuntu, angeke afakwe kwi-index, futhi asuswa ngaphakathi kwemizuzu yokuqedwa. Ifasitela lokugcinwa libhalwe ku /privacy/ futhi asishicileli lutho oluqeqeshiwe oluvela ku-uploads womsebenzisi.

MOV

I-MOV iyifomethi ye-QuickTime ye-Apple, esekela ividiyo nomsindo wekhwalithi ephezulu wokuhlela kobungcweti.

AV1

I-AV1 iyifomethi yokuminyanisa ividiyo evulekile, engenanzuzo eyenzelwe ukusakazwa kahle kwevidiyo nge-inthanethi. Inikeza ukusebenza kahle kokucindezela okuphezulu ngaphandle kokuyekethisa ikhwalithi yokubukwayo.
