AV1 kuya WebM Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani i-AV1 ku-WebM ngaphandle kokulahlekelwa yikhwalithi yevidiyo?

Layisha phezulu ihele lakho AV1 futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless WebM output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / ubunjani obuphezulu). I-codec ikhethiwe ukufana ne WebM container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. AV1 yi-codec, hhayi isiqoqi — i-bitstream ihamba ngaphakathi MP4 noma WebM, ixhunywe ne-Opus noma i-AAC umsindo. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi.

I AV1 yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe WebM?

Akunakuthembeka. AV1 igcina imisindo eminingi njengezingoma zohlobo lokuqala, kodwa WebM uxhaso lokudlala ngaphezu kwengoma yokuqala akulingani, ngakho abadlali abaningi bazoveza kuphela eyodwa. Khetha ingoma oyifunayo ngaphambi kokuguqula; abanye bakhishwa kahle kumafayela abo ngaphezu kokushiya emgodini ofihlayo. AV1 inikeza cishe 30% engcono ucindezelo kuna H.264 esezingeni elifanayo futhi ithatha akukho izinkokhelo izitifiketi, okuyinto kungani YouTube ne Netflix push it. WebM ilungile encane noma kuphi ngaphandle kwe-browser - ama-video editors, amafoni 'ama-galleries asekhaya nama-Smart TVs ahlala engaziboni.

Ingabe WebM 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 WebM isebenzisa?

Kuxhomekeka ku WebM isihlungi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhurawuza, nama-Smart TVs. MKV iphutha ku-H.265 / HEVC ukuze kube nengxenye yobukhulu befayela ngekhwalithi elinganayo. WebM iphutha ku-VP9. Izinketho eziphezulu zibonisa ngokucacile ukhetho lwe-codec uma ufuna ukucima. I-WebM iyingxenye eqinile ye-Matroska eshicilelwe yi-Google ngo-2010 ekhethekile ekubeni yividiyo ye-HTML5 equkethwe ngaphandle kwe-royalty.

Ingabe umsindo wami uzophila ukuguqulwa AV1 kuya ku WebM?

Yebo. Uma AV1 ne WebM zihlanganisa i-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka ikhowudi — okufanayo. Uma ama-codecs ahlukile, umsindo uguqulwa ube yi-AAC / Opus / Vorbis ngokuya ngomsebenzi oxhaswa yi-WebM. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula AV1 ku WebM?

Ngokungagqibekanga yebo — i-24fps AV1 ihlala i-24fps ku-WebM; i-60fps AV1 ihlala i-60fps. Uma ufuna ukuguqula isilinganiso (isibonelo, interlaced 29.97 → progressive 30, noma 60 → 30 ukulayisha amaphesenti), isinqumo se-framerate siphatha 3:2 ukukhishwa, ukususwa kwe-interlacing, kanye nokuhlanganisa ifreyimu ku-encoding pass.

Ingabe ubukhulu behele bushintsha kanjani kusuka ku AV1 kuya ku WebM?

Same-codec re-mux (AV1 H.264 → WebM H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 ngokuvamile uhlukanisa ihele ngengxenye ngekhwalithi efanayo yokubuka; VP9 ifana kakhulu; AV1 ihlukanisa ezinye i-20-30% kodwa ihamba kancane uku-encode.

Ingabe ihele WebM lidlalwa ku-iPhone, Android, ne-Smart TVs?

MP4 / H.264 idlala ngokusemthethweni kuwo wonke amadivayisi amanje. MOV / H.264 idlala kumadivayisi we-Apple nakwamanye ama-TV kodwa hhayi njalo kuma-Android adala. MKV idinga i-VLC ku-iOS. I-WebM iyisiphequluli-kuqala. Izinketho ezithuthukisiwe zifaka phakathi "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-WebM codec / ibhokisi eliphephile lenjongo yakho. I-WebM idlala ngokusemthethweni kuwo wonke umsakazi omusha ngaphandle kweplugin, ngaphandle kwelayisense yemali kanye nokungabonisi kwepatent, okuyenza ibe yiphutha levidiyo efakwe kwi-web.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-AV1 yevidiyo yehora elilodwa ibe yi-WebM?

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

Yini isixazululo esiphezulu esixhaswe yi AV1 kuya ku WebM?

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-AV1 ne-WebM amabhokisi axhasa khona.

Ingabe i-AV1 yami yevidiyo imfihlo ngesikhathi sokuguqulwa ku-WebM?

Yebo. Amafayela wevidiyo alayishwe phezulu aphathwa ngabasebenza ngokuzimela, angeke abone umuntu, angeke afakwe kwi-index, futhi asuswa ngaphakathi kwemizuzu yokuqedwa. Ifasitela lokugcinwa libhalwe ku /privacy/ futhi asishicileli lutho lokuqeqesha kusuka ku-uploads yomsebenzisi.

Ingabe ngingakwazi ukujika, ukucisha, noma ukujikelezisa ngesikhathi sokuguqulwa AV1 kuya ku WebM?

Akunakwesinye isikhashana — sebenzisa /video-trim/ noma /video-cutter/ ukucima kuqala, bese uqhuba ukuguqulwa AV1 → WebM. Ukuhlukanisa futhi ukuguqula kushesha kunakuphinde ukuguqula wonke ama-AV1 ukuze ushiye izithombe ezingasebenzi.

AV1

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