WebM kuya AV1 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi WebM ku AV1 ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Layisha phezulu ifayela lakho WebM 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. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi. AV1 yi-codec, hhayi isiqoqi — i-bitstream ihamba ngaphakathi MP4 noma WebM, ixhunywe ne-Opus noma i-AAC umsindo.

Ingabe i-AV1 ingagcina ama-tracks omsindo angaphezu kwesinye?

Yebo, futhi kuyithuthukiso eliyiqiniso ku WebM. AV1 iphatha wonke umsindo njengohlelo oluhle, ngakho-ke umsindo ovela ku-language, i-dub kanye nombhali we-comment ungahlala kuhele olulodwa nomdlalo oshintsha phakathi kwazo uma kudingeka. AV1 inikeza cishe 30% engcono ucindezelo kuna H.264 esezingeni elifanayo futhi ithatha akukho izinkokhelo izitifiketi, okuyinto kungani YouTube ne Netflix push it.

Ingabe AV1 isekela izibonisi zesiqephu ezi WebM azisebenzisi?

Ikwenza. AV1 igcina amasigaba njengedatha ye-meta eqoqayo, ngakho ukurekhodwa okude kungafinyelelwa ngengxenye endaweni yokuhlanza ibha yokuqhubekela phambili. WebM ayikho indawo yokubeka lo lwazi, ngakho uma umsuka uthunyelwe ngohlu lwesigaba, kwakuyihele le-sidecar — nikela ngalo ku-converter futhi libhalwe ku-AV1.

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

Kungenzeka ukuthi ayisebenzi. WebM 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, WebM 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 WebM kuya ku AV1?

Yebo. Uma WebM 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 WebM ku AV1?

Ngokungajwayelekile yebo — i-24fps WebM ihlala i-24fps ku-AV1; i-60fps WebM 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 WebM kuya ku AV1?

Same-codec re-mux (WebM 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-WebM 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 WebM → AV1 iphele ngemizuzu engu-18-40 ngokuya ngesinqumo ne-codec ethengiswayo.

Yini isixazululo esiphezulu esixhaswe yi WebM 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-WebM ne-AV1 amabhokisi axhasa khona.

WebM

I-WebM yenzelwe iwebhu, inikeza ukusakaza ividiyo ngaphandle kwemali yokukhokha ngama-codec e-VP8/VP9.

AV1

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