M4V ukuba MKV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4V ibe yi-MKV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye M4V kwaye umguquli uqhube i-CRF-esekelwe kwi-encoding ephindayo ebhekisa kwi-visually-lossless MKV imveliso (i-CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne MKV isiqulathi-zifayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 yee-pipelines ezintsha. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata. MKV yi-codec-agnostic: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye.

Kutheni le nto ifayili yam M4V ayiphumelelanga ukutshintshela kwi MKV?

Iifayile ze M4V zifihliweyo kwinqanaba le bitstream yindawo yokurhweba okanye isoftware ekhupha ifayile, kwaye umjelo ofihliweyo awunakucodwe sisi okanye ngantoni na ngaphandle kwesitshixo selayisensi. Iifayile ozirekhode, ozirhwebe ngaphandle okanye ozikhuphele ezantsi azikhuselwanga ziguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo, kwaye akukho mguquli uthembekileyo okwaziyo ukuthembisa okuthile. I-DRM-ikhuselwe i-M4V ithengiso ayikwazi ukutshintshwa yinto; kuphela iifayili ezikhuselweyo ze-M4V ziyatshintshwa, kwaye abadlali abangama-Apple bafuna uluhlu olubizwa kwakhona.

Ingaba i MKV iyaqhubeka idlala ngokulula kwifowuni okanye kwiTV?

Ingaba ayikwazi. M4V ikhowudiwe yisilicon ekhethekileyo kwifowuni, iitablethi kunye neeTV, nto leyo eyenza ukuba idlala ngaphandle kokutyibilika kwebhetri. MKV ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, M4V yindawo ekhuselekileyo yokugcinwa ehlala kuyo. MKV ayinaso nasiphi na isixhaso sehardware esisemthethweni - iifowuni, iziphene kunye neeTV zihlala zifuna i-VLC okanye i-remux phambi kokuba zidlale.

Zonke ii M4V ne MKV ziibhokisi ezitsha — yeyiphi endingayenza?

Gcina naziphi na izilinganiso apho ifayile isiya khona, kuba akukho nto ingcono kwingcambu. Enye yazo ezimbini iyenziwe ukudlala uhambelana kunye nenye yokugcina konke ifayile ingaquka, kwaye barhweba nganye nganye ngokuchanekileyo ngaphaya komgca. Impendulo esebenzayo yeelayibrari ezininzi kukugcina kwibhokisi enamandla yomsebenzi kwaye urhwebe ngaphandle kwinye ehambelanayo kwisicelo. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhoboshela kwifayili enye.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MKV?

Ixhomekeke kwi MKV 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. MKV yi Matroska, ibhokisi evulekileyo eyenziwe ngo 2002 ngaphandle kweengxaki zonikezelo lwelayisensi kunye nokungaphelelanga kwinto engayigcinayo.

Ingaba umculo wam wesandi uya kuqhubeka uguquka ukusuka kwi M4V ukuya kwi MKV?

Ewe. Xa M4V ne MKV 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-MKV ixhasa ntoni. I-audio enezithotho ezininzi (iingxelo, iilwimi ezitshintshiweyo) igcinwa.

Ndingagcina i-framerate yokuqala xa ndiguqula i-M4V ibe yi-MKV?

Ngokungagqibekanga ewe — i-24fps M4V ihlala i-24fps kwi-MKV; i-60fps M4V 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 M4V ukuya kwi MKV?

I-codec efanayo yokuphinda-phinda (M4V H.264 → MKV 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 MKV 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-MKV codec / isiqulathi esikhuselekileyo senjongo yakho.

Ithatha ixesha elingakanani ukutshintsha i-M4V yevidiyo yeyure enye ibe yi-MKV?

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 M4V → MKV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi M4V ukuya kwi MKV?

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 M4V ne MKV iinqanawa zixhasa khona.

Ingaba i-M4V yevidiyo yam ifihlakeleyo ngexesha liguqulwa libe li MKV?

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.
