MKV ukuba M4V Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye-MKV kwaye umisele Umgangatho kwiNtlonipho eNkulu kwizinto ezikhethwayo zokuguqula. Oku kuphinda kuqulethe ividiyo kwisicwangciso esiphezulu somgangatho (CRF 18 ye-H.264 ne-VP9 output), egcina inkcukacha ezininzi kwixabiso lefayili enkulu. Okumiselweyo, Okuthe nkqo, sebenzisa isicwangciso esiqhelekileyo. I-M4V output ifumana i-codec exhasa isiqulathi seefayili: H.264 ye-MP4, MOV ne-MKV, VP9 ye-WebM. 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. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata.

Zonke ii MKV ne M4V 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-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhoboshela kwifayili enye. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo.

Yeyiphi i-codec yevidiyo esetyenziswa yi-M4V?

Oku kuxhomekeke kwi-M4V container. I-MP4, MOV ne-MKV output isebenzisa i-H.264, edlala kwifowuni yonke, umkhangeli zincwadi neTV. I-WebM output isebenzisa i-VP9. I-AVI, WMV ne-MPEG output isebenzisa ii-codecs ezidala ezo fomati zaphuhliswa kuzo. M4V yi-Apple's MP4, esetyenziswa yi-iTunes ne-Apple TV app yefilimu kunye ne-TV.

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

Ewe, umculo ophambili wesandi udlula, uphinde ukhowudiwe kwi-codec i-M4V idlala, umzekelo i-AAC kwi-MP4 ne-MOV okanye i-Opus kwi-WebM. Iindawo ezininzi zokuguqulela zigcina kuphela umculo omnye (onye oneendawo ezininzi), ngoko ke iilwimi ezitshintshiweyo kunye nolwazi olusisiseko lulahliwe. I-MP4 ukuya kwi-MOV, ne-AVI, WMV, MPEG, FLV, VOB okanye M4V ukuya kwi-MKV, gcina wonke umculo wesandi.

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

Ewe. Umyinge we-frame igcinwa ngaphandle kokuba uyitshintshe: i-24 fps MKV ihlala i-24 fps kwi-M4V. Ummiselo we-Frame Rate unokuguqula ibe yi-60, 30 okanye i-24 fps. Itshintsha kuphela umyinge; ayitshintshi i-interlace yevidiyo okanye isuse i-3:2 pulldown.

Ubungakanani befayili butshintsha njani ukusuka kwi MKV ukuya kwi M4V?

Oku kuxhomekeke ekubeni kwenzeka ntoni kwividiyo. I-MKV ukuya kwi-MP4 okanye i-MOV ngemimiselo emiselweyo ikopa umsinga wevidiyo ungatshintshwanga, ngoko ubungakanani buhlala bufutshane nomcebo. Ezinye iipere ziphinda ziyikhowudi: i-MKV ene-bitrate ephezulu ihlala iphuma incinci, ngelixa enye ekhoyo icinezelwe kakhulu ikhula. Ifayile encinci phantsi koBunjani inika imveliso encinci, kwaye i-H.265 kuMmiselo weCodec (MP4, MOV ne-MKV) ihlala incinci kune-H.264 kwi-quality efana nayo kodwa idlala kwizixhobo ezincinci.

Ingaba ifayili M4V iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 kunye H.264 idlala kwi-smartphone, i-browser kunye ne-TV. MOV kunye ne-H.264 idlala kwi-Apple kunye ne-TV ezininzi kodwa hayi kwi-smartphone ye-Android edala. MKV ifuna i-app efana ne-VLC kwi-iOS, kwaye i-WebM ihlala ekhaya kwii-browser. Akukho sixhobo esimiselweyo kule phepha, ngoko khetha ifomati efanelekileyo yesixhobo sakho esixhasayo. I-DRM-ikhuselwe i-M4V ithengiso ayikwazi ukutshintshwa yinto; kuphela iifayili ezikhuselweyo ze-M4V ziyatshintshwa, kwaye abadlali abangama-Apple bafuna uluhlu olubizwa kwakhona.

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

Akukho xesha elimiselweyo: lixhomekeke kubungakanani, ubungakanani obucacileyo kunye nohlobo lwenjongo. Uguqulelo luyasebenza kwiseva yethu ye-CPUs kunye nesoftware encoders; akukho GPU ekhawulezayo. MKV ukuya MP4 okanye MOV ngemimiselo emiselweyo ikopa umsinga wevidiyo kwaye ikhawuleza kakhulu. Ukuphinda uguqulele kwi-H.264 kuthatha ixesha elide, kwaye i-WebM (VP9) yinjongo ekhawulezayo, iphinda ikhawuleze kakhulu kune-H.264 kwiimvavanyo zethu.

Yintoni ubukhulu bomfanekiso oxhaswayo kwi MKV ukuya kwi M4V?

Umguquli awunaso isiphelo somfanekiso ocacileyo; umda ubungakanani bokukhuphela obuvunyelweyo kwinkqubo yakho, kwaye umfanekiso ocacileyo uhlala njengonjalo ngaphandle kokuba ukhetha i-1080p, 720p okanye 480p. Akukho HDR uqhubekeko okanye umbala wokumaphu. Xa umsinga wevidiyo ukopiwe (MKV ukuya kwi MP4 okanye MOV ngemimiselo emiselweyo), i-HDR10 idlula ngaphandle kokuxhathisa. Ukuphinda ukhowudi ukhupha i-HDR10 ulawulo lwemetadata, kunye noBunjani, Ubunjani okanye i-Frame Rate ucwangciso ezinye iipere zikhupha ividiyo kumbala we-8-bit, ngoko i-HDR MKV ingabonakalisa i-washed out.

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

Ewe. Iifayile ezilayishwe phezulu ze MKV ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe M4V kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Ndingatywina, ndiyimise, okanye ndiyijikelezise ngexesha lokuguqulwa kwe MKV ukuya kwi M4V?

Ayikho kwinyathelo elifanayo. Sebenzisa /trim-video/ okanye /video-cutter/ ukucima i-MKV kuqala, okanye /rotate-video/ ukujika, emva koko qhuba i-MKV ukuya kwi-M4V uguqulelo. Ukucima kuqala kukhawulezayo kune-re-encoding ye-MKV yonke ukushiya imifanekiso engasebenziswanga.

Kutheni le nto ifayili M4V imnyama xa ithelekiswa nomboneleli MKV?

Imveliso iqhutywa ngokuqhelekileyo iqhutywe ngokunzima kunendawo yokungena. Vula uguqulelo lwezinto ezikhethwayo, khetha Ubunjani Obuphezulu phantsi koBunjani, gcina Ugqibo kuBunjineli kwaye uguqule kwakhona. Akukho CRF okanye ilizwe le bitrate kule phepha; Ubunjani Obuphezulu yinkqubo egcina inkcukacha ezininzi.
