MKV ukuba AV1 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i MKV ibe yi AV1 ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho MKV kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless AV1 imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne AV1 isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines. I-MKV ayisebenzisi i-codec: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye. AV1 yi-codec, hayi isiqulathi-zifayili — i-bitstream ihamba ngaphakathi kwe-MP4 okanye i-WebM, idityaniswe ne-Opus okanye i-AAC yesandi.

Ingaba i AV1 iyadlala kwisikhangeli xa i MKV ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A MKV efakwe kwiphepha le web okanye ibonisa umdlali olahlwayo okanye iforce ulwaleko, kuba ibrowser ayithuthinga i decoder kuyo. AV1 idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. AV1 ibonelela nge-30% yoxinzelelo olungcono kune-H.264 kwinqanaba elifanayo lomgangatho kwaye ayikho iindleko zelayisensi, oko kukuthi, iYouTube ne-Netflix iqhuba.

Ingaba i AV1 iquka isiqulathi seefayili okanye i-codec, kwaye ngaba itshintsha into endiyifumanayo kwakhona?

Itshintsha into elindelekeyo kwifayile yemveliso. Icala elinye loguqulelo libiza ukukhowuda kunokuba ujikeleziso, ngoko oko kubuyela umva kukujikelezo lweebit ngaphakathi komgquba olungeleyo - ngokuqhelekileyo MP4 okanye MKV. Ulwandiso lubonisa umgquba; i codec yiyo eyaziyo ubungakanani befayile kwaye apho izakudlalwa khona.

Yeyiphi i-codec yevidiyo esetyenziswa yi-AV1 yemveliso?

Ixhomekeke kwi AV1 isiqulathi seefayili. I-MP4 imiselwe ukuba i-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, iibrowser, kunye neSmart TVs. I-MKV imiselwe ukuba i-H.265 / HEVC ukuze ijikeleze i-half of the file size at equivalent quality. I-WebM imiselwe ukuba i-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. AV1 yi-codec yevidiyo engenamda we-royalty i-Alliance for Open Media ekhutshwe ngo-2018 njengento elandelayo kwi-VP9.

Ingaba umculo wam wesandi uya kuqhubeka uguquka MKV ukuya AV1?

Yes. When MKV and AV1 share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the AV1 container supports. Multi-track audio (commentary, alternate languages) is preserved.

Ndingagcina i-framerate yokuqala xa ndiguqula i-MKV iye kwi-AV1?

Ngokungagqibekanga ewe — i-24fps MKV ihlala i-24fps kwi-AV1; i-60fps MKV ihlala i-60fps. Ukuba ufuna ukuguqula umyinge (umzekelo, i-interlaced 29.97 → i-progressive 30, okanye i-60 → 30 yokukhuphela umda), ukhetho lobungakanani be-frame luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokukopela.

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi MKV ukuya kwi AV1?

I-codec efanayo yoku-mux (MKV H.264 → AV1 H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayile kwinqanaba elifanayo lomgangatho obonakalayo; VP9 imalunga nokuthelekiswa; AV1 iquka enye i-20-30% kodwa ihamba phantsi ukukopela.

Ingaba ifayili AV1 iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo zeApple kunye neTV ezininzi kodwa hayi rhoqo kwi-Android edala. MKV ifuna i-VLC kwi-iOS. WebM ikwi-browser-first. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-AV1 codec / isiqulathi seefayili esikhuselekileyo so target yakho. Ukukhowuda kwe-AV1 kukhawuleza, kwaye izixhobo zokuqokelela ikhowudi zavela kuphela kwifowuni kunye neTV ukusukela ngo-2020 ukuya phambili - iizixhobo ezidala zibuyela kwisoftware efuna amandla yokuqokelela ikhowudi.

Ithatha ixesha elingakanani ukutshintsha i-MKV yevidiyo yeyure enye ibe yi AV1?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo iqhuba ngokuthe ngqo kwi-0.3-0.7x yobude bomthombo kwi-GPU yethu, ngoko ke i-1-hour MKV → AV1 igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bokubonisa obuxhaswa yi MKV ukuya kwi AV1?

Ukuya kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngobukhulu befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini MKV ne AV1 iziqulathi zixhasa khona.

Ingaba i-MKV yevidiyo yam ifihlakeleyo ngexesha lokuguqulwa kwi-AV1?

Ewe. Iifayili zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo, aziboniswanga ngumntu, azikho kwisicwangciso, zicinywa ngaphakathi kwemizuzu yokuphela. Ifestile yokugcina ibhalwe kwi /privacy/ kwaye asipapashi naziphi na iziqu zemfundo ezisuka kubasebenzisi abalayishwe phezulu.

Ndingayicima, ndiyibeke phantsi, okanye ndiyijikelezise ngexesha lokuguqulwa kwe MKV ukuya kwi AV1?

Ayikho kwinyathelo elifanayo — sebenzisa /video-trim/ okanye /video-cutter/ ukucima kuqala, emva koko qhuba u MKV → AV1 uguqulelo. Ukudibanisa ukusika nokuguqula kukhawulezayo kune-re-encoding yonke i MKV ukushiya kuphela imifanekiso engasebenziswanga.

MKV

I-MKV (Matroska) inokugcina iividiyo, iaudio, kunye neengoma ezingezantsi ezingenamda kwifayile enye, efanelekileyo kwiimuvi.

AV1

I-AV1 yifomathi yocinezelo yevidiyo evulekileyo, engenabukhosi eyenzelwe ukusasazwa kwevidiyo ngokufanelekileyo kwi-intanethi. Ibonelela ngokusebenza kakuhle koxinzelelo ngaphandle kokubeka esichengeni umgangatho wokubonwayo.
