MKV ukuba MP4 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i MKV ibe yi MP4 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-MP4 output ifumana i-codec exhasa isiqulathi seefayili: H.264 ye-MP4, MOV ne-MKV, VP9 ye-WebM. 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. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi seefayili sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9.

I MKV yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi MP4?

Hayi. Umguquli ugcina umculo omnye wesandi, owona mculo unamandla kakhulu (oqhelekileyo uthelekiso oluphambili), kwaye ukhupha onke; akukho mmiselo wokukhetha omnye ohlukileyo. Ukugcina omnye umculo, yenza kwakhona i-MKV ngomsebenzi wokuqala (i-VLC okanye i-ffmpeg ingakwenza oku), emva koko uyiguqule. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhobosha kwifayili enye. I-MP4 ixhasa kuphela ifomati enye ethandwayo yesihloko esingaphantsi (mov_text), nesandi esininzi esingenakuthembeka ngaphandle kwabadlali be-desktop.

Ingaba i MP4 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. MP4 idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. I-MP4 yindawo ekhuselekileyo yokunikezelwa kweenkqubo ezifumanekayo - yonke ifowuni, ibrowser, i-console, umhleli kunye neSmart TV eyenziwe kwiminyaka elishumi edlulileyo idlala ngaphandle kwesoftware engaphezulu.

Zonke ii MKV ne MP4 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.

Yeyiphi i-codec yevidiyo esetyenziswa yi-MP4 yemveliso?

Oku kuxhomekeke kwi-MP4 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. I-MP4 yi-ISO/IEC 14496-14, imiselwe ngo-2001 kwaye ivela kwibhokisi yobeko lwe-QuickTime efanayo ne-MOV esetyenziswa.

Ingaba umculo wam wesandi uya kuqhubeka uguquka MKV ukuya MP4?

Ewe, umculo ophambili wesandi udlula, uphinde ukhowudiwe kwi-codec i-MP4 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 iye kwi-MP4?

Ewe. Umyinge we-frame igcinwa ngaphandle kokuba uyitshintshe: i-24 fps MKV ihlala i-24 fps kwi-MP4. 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.

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi MKV ukuya kwi MP4?

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.

Ithatha ixesha elingakanani ukutshintsha i-MKV yevidiyo yeyure enye ibe yi MP4?

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 bokubonisa obuxhaswa yi MKV ukuya kwi MP4?

Umguquli awunaso isiphelo somfanekiso ocacileyo; umda ubungakanani bokukhuphela obuvunyelweyo kwinkqubo yakho, kwaye umfanekiso ocacileyo uhlala njengonjalo ngaphandle kokuba ukhetha i-1080p, 720p okanye 480p.

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 lokuguqulwa kwi-MP4?

Ewe. Iifayile ezilayishwe phezulu ze MKV ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe MP4 kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.
