MP4 ukuba MKV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MP4 ibe yi-MKV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho ye MP4 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. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9. 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.

Ingaba i MKV igcina ngaphezulu kwengoma enye yesandi?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe MP4. MKV iphatha yonke imijelo yesandi njengento ephambili, ngoko udidi lwesivakalisi sokuqala, i-dub kunye nomlawuli wengxelo ingaphila kwifayile enye nomdlali otshintshela phakathi kwabo kwisicelo. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhoboshela kwifayili enye.

Ingaba i MKV inkxaso yamachaphaza ophawu anjengoko MP4 ayizange ikwenze?

Iyenza. MKV igcina izihloko njenge metadata yesiqulathi seefayili, ngoko ushicilelo olude lunokuqhubela phambili ngecandelo endaweni yokucoca ibar yokuqhubekeka. MP4 ayinanto yokubeka loo nkcukacha, ngoko ukuba umthombo uthunyelwe ngoluhlu lwesihloko yayikwifayile ye sidecar - inikezele kuguquleli kwaye ibhalwe kwi MKV.

Ndingayifaka njani ifayili kwiphepha le-web emva kokuguqula i-MP4 ibe yi-MKV?

Ayi ngqo. MP4 idlala umgca kwisixhobo sokukhangela yonke; MKV ayisebenzi, ngoko ke iphepha elidibanisa ibuyela umva kwikhonkco lokulayisha okanye isakhelo somdlali ongenanto. Ukuba ifayile icwangciswe kwiwebhusayithi, gcina i MP4 kwi-web kwaye uthathe i MKV njenge-archive okanye uhlela ikopi. MKV ayinaso nasiphi na isixhaso sehardware esisemthethweni - iifowuni, iziphene kunye neeTV zihlala zifuna i-VLC okanye i-remux phambi kokuba zidlale.

Ingaba i MKV iyaqhubeka idlala ngokulula kwifowuni okanye kwiTV?

Ingaba ayikwazi. MP4 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, MP4 yindawo ekhuselekileyo yokugcinwa ehlala kuyo.

Zonke ii MP4 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-MP4 yindawo ekhuselekileyo yokunikezelwa kweenkqubo ezifumanekayo - yonke ifowuni, ibrowser, i-console, umhleli kunye neSmart TV eyenziwe kwiminyaka elishumi edlulileyo idlala ngaphandle kwesoftware engaphezulu.

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 MP4 ukuya kwi MKV?

Ewe. Xa MP4 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-MP4 ibe yi-MKV?

Ngokungagqibekanga ewe — i-24fps MP4 ihlala i-24fps kwi-MKV; i-60fps MP4 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 MP4 ukuya kwi MKV?

I-codec efanayo yokuphinda-phinda (MP4 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-MP4 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 MP4 → MKV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.
