MOV ukuba AV1 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MOV ibe yi-AV1 ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye MOV kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless AV1 imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne AV1 isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. I-MOV ihlala ihambisa i-H.264 okanye i-HEVC yokuhambisa, okanye i-ProRes xa i-editor master, ecaleni kwe-AAC okanye i-PCM engenakucothayo. 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 MOV ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A MOV 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 iyaqhubeka idlala ngokulula kwifowuni okanye kwiTV?

Ingaba ayikwazi. MOV ikhowudiwe yisilicon ekhethekileyo kwifowuni, iitablethi kunye neeTV, nto leyo eyenza ukuba idlala ngaphandle kokutyibilika kwebhetri. AV1 ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, MOV yindawo ekhuselekileyo yokugcinwa ehlala kuyo. 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.

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?

Ixhomekeke kwi AV1 isiqulathi seefayili. I-MP4 imiselwe ukuba ibe yi-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, ii-browser, kunye ne-Smart TVs. I-MKV imiselwe ukuba ibe yi-H.265 / HEVC ukuze ilinganise nengxenye yobungakanani befayili kwinqanaba elifanayo lomgangatho. I-WebM imiselwe ukuba ibe yi-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 ukusuka kwi MOV ukuya kwi AV1?

Ewe. Xa MOV ne AV1 zibelana nge-codec yesandi (umzekelo, zombini zithabatha i-AAC), isandi siphinda sixutywe ngaphandle kokubuyisela ukukhowuda - i-bit-identical. Xa ii-codecs zihlukile, isandi siguqulwa kwi-AAC / Opus / Vorbis kuxhomekeke ekubeni i-AV1 ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-MOV ibe yi-AV1?

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

Ubungakanani befayili butshintsha njani ukusuka kwi MOV ukuya kwi AV1?

I-codec efanayo yokuphinda-phinda (MOV H.264 → AV1 H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayili kwinqanaba elifanayo lomgangatho wokubona; VP9 imalunga nokuthelekiswa; AV1 icima 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 ze-Apple 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 esikhuselekileyo senjongo yakho.

Ithatha ixesha elingakanani ukutshintsha i-MOV 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 ephinda-ikhowudi iqhuba malunga nexesha lomthombo we-0.3-0.7x kwi-GPU yethu, ngoko ke i-1-iyure MOV → AV1 igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi MOV ukuya kwi AV1?

Ukuza kuthi ga kwi-8K (7680×4320) kwi-premium plans. Ukuguqulwa simahla kugqityiwe kwi-4K (3840×2160) ngumda wobungakanani befayili nganye. I-HDR metadata (HDR10, HDR10+, Dolby Vision xa ikhona) iqhutywa apho zombini i MOV ne AV1 iinqanawa zixhasa khona.

Ingaba i-MOV yevidiyo yam ifihlakeleyo ngexesha liguqulwa libe li AV1?

Ewe. Iifayili zevidiyo ezilayishwe phezulu ziqhubekekiswa kubasebenzi abakhethekileyo, azisoloko zijongwa ngumntu, azisoloko zidweliswe kwisikhombisi, kwaye zicinywa kwimizuzu embalwa emva kokuphela. Ifestile yokugcina ibhalwe kwi /privacy/ kwaye asipapashi naziphi na iziqu zesifundo ezivela kubasebenzisi abalayishwe phezulu.

MOV

I-MOV yifomathi ye-QuickTime ka-Apple, exhasa ividiyo kunye nesandi esikumgangatho ophezulu sokuhlela ngobuchwephesha.

AV1

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