WebM kuya AV1 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi WebM ku AV1 ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Ukufaka ifayela lakho WebM futhi hlela Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The AV1 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. 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. i-AV1 igcina amasigaba njenge-metadata yebhokisi, ngakho ukurekhoda okude kungafinyelelwa ngengxenye endaweni yokuhlanza ibha yokuqhubekela phambili. i-WebM ayinaso isikhala sokubeka le lwazi, ngakho i-AV1 eguqulwe iqala ngaphandle kwamasigaba; yongeza izibonisi ngemuva ngethuluzi njenge-MKVToolNix noma i-ffmpeg.

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, MOV kanye MKV output ukusebenzisa H.264, okuyinto idlala ku ngempela wonke ifoni, ibrowser kanye TV. WebM output usebenzisa VP9. AVI, WMV kanye MPEG output ukusebenzisa codecs older labo amafomethi akhiwa. 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, umsindo omkhulu ohambayo udlula, uphinde ukhodwe ku-codec i-AV1 idlala, isibonelo, i-AAC ku-MP4 ne-MOV noma i-Opus ku-WebM. Ukuguqulwa okuningi kugcina kuphela umsindo owodwa (omunye onezintambo eziningi), ngakho-ke izilimi ezihlukile nezibuyekezo zilahlekile. MP4 kuya ku-MOV, ne-AVI, WMV, MPEG, FLV, VOB noma M4V kuya ku-MKV, gcina wonke umsindo ohambayo.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula WebM ku AV1?

Yebo. Izinga lefreyimu ligcinwa ngaphandle kokuthi ushintshe: i-24 fps WebM ihlala i-24 fps ku-AV1. Uhlelo lwezinga lefreyimu lingaguqulwa libe yi-60, 30 noma i-24 fps. Lishintsha kuphela inani; alisusanga ividiyo noma lisuse i-3:2 pulldown.

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

Kuxhomekeka kulokho okwenzekayo kuvidiyo. MKV MP4 noma MOV nge default izilungiselelo ikhophi ividiyo umfutho engashintshiwe, ngakho ubukhulu ihlala eduze komthombo. Ezinye izibini eziningi ziphinde zikhophi: a high-bitrate WebM ngokuvamile ephuma ncane, ngenkathi ekhona kakhulu ecindezelwe eyodwa ingakhula. Ifayela elincane ngaphansi Quality inikeza inzuzo encane, futhi H.265 ku Codec isilungiselelo (MP4, MOV ne MKV) ngokuvamile ncane kuna H.264 ku quality efana kodwa idlala ku amadivayisi ambalwa.

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

MP4 ne H.264 idlala kunoma iyiphi ifoni, i-browser kanye TV. MOV ne H.264 idlala kunoma iyiphi idivayisi Apple kanye TVs eziningi kodwa hhayi kunoma iyiphi ifoni Android edala.

Akukho isikhathi esiqinile: sixhomekeke kude, isixazululo kanye nefomethi efanelekayo. Ukuguquka kuqhutshwa kumaseva ethu we-CPUs ngesoftware encoders; akukho GPU ukukhawulelwa. MKV kuya MP4 noma MOV ngezinhlelo ezijwayelekile zikopishe umsinga wevidiyo futhi zisheshe. Ukuphinda-ukuguqula ku-H.264 kuthatha isikhathi eside, futhi WebM (VP9) yinjongo ehamba kancane, izikhathi eziningi ezihamba kancane kune-H.264 ezivivinyweni zethu.

Yini isixazululo esiphezulu esixhaswe yi WebM kuya ku AV1?

Umguquli awunakho ubukhulu obuphelele obuphelele; umkhawulo ubukhulu bokufaka obuvunyelwe kuhlelo lwakho, futhi ubukhulu buhlala bukhona uma ungakhethanga 1080p, 720p noma 480p. Akukho HDR ukucubungula noma ukumayelana nombala. Uma ividiyo ikhophiwe (MKV kuya MP4 noma MOV ngezinhlelo ezijwayelekile), HDR10 idlula ngaphandle kokuchofoza. Ukuphinde ubhale kabusha i-HDR10 mastering metadata, futhi ngekhwalithi, ubukhulu noma i-frame rate ilungiselelo ezinye izibini zikhuphula ividiyo kumbala we-8-bit, ngakho-ke i-HDR WebM ingabonakalisa i-washed out.

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.
