MKV kuya MP4 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-MKV ibe yi-MP4 ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Akukho sinqumo sokudlulisa-kopela kule khasi. Amaqembu ambalwa adlulisa umsindo wevidiyo ohambisanayo kwi-MP4 container ngaphandle kokuwuphindela, MKV kuya ku-MP4 phakathi kwazo, okusheshayo futhi akulahleki ubuhle. Amaqembu amaningi adlulisa ividiyo. MKV i codec-agnostic: H.264, HEVC, VP9 kanye AV1 ividiyo uhlala ejabulisayo eduze AAC, FLAC, Opus, DTS noma Dolby umsindo kwifayela efanayo. Kuyinto encane kakhulu ukuthi wonke ama-MP4 aphilayo ayizividiyo ze-H.264 ezinesandi se-AAC; isiqoqi sigcina ngokusemthethweni i-HEVC, AV1 ne-VP9.

I MKV yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe MP4?

Akunalutho. Umguquli ugcina umsindo owodwa, owenza ama-channels amaningi (okungukuthi, umsindo oyinhloko), futhi ususa okunye; akukho sinqumo sokukhetha okuhlukile. Ukugcina umsindo owodwa, shintsha i-MKV nge-track yokuqala (i-VLC noma i-ffmpeg ingakwenza lokhu), bese uyiguqula. I-MKV iyindawo yokugcina ekhethiwe ngoba igcina imisindo engaphelelanga, izihloko ezilula, izihloko eziphawulekayo kanye nezithombe zobuso kwifayela elilodwa. I-MP4 isekela kuphela ifomu elilodwa lesihloko esihlonishwa kakhulu (mov_text), futhi umsindo we-multi-track awuthembeki ngaphandle kwama-players wedesktop.

Ingabe i-MP4 izodlala kwi-browser uma i-MKV ingadlalanga?

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I MKV efakwe kwikhasi lewebhu ibonisa umdlali okhubazekile noma icindezela ukulayisha, ngoba iziphequluli azikho izikhombisi ezizo. MP4 idlala ngaphakathi ngengxenye yevidiyo ye-HTML5 engavamile ngaphandle kweplugin noma kusetshenziswa okungaphandle. MP4 yindawo ephephile yokufinyelela ekhona — yonke ifoni, i-browser, i-console, umhleli ne-Smart TV eyenziwe eminyakeni eyisithupha edlule idlala ngaphandle kwesoftware engeziwe.

Zonke MKV ne MP4 ziyizihlungi ezisha — yiziphi okufanele ngizigcine?

Gcina noma yikuphi okuhambisana lapho ihele lihamba khona, ngoba akukho okungcono ku-abstract. Enye yalezi ezimbili ifakwe ukuhambisana kokudlala futhi enye igcinwa konke ohele angaba nalo, futhi zihweba ngazo zonke ngaleyo ngxenye. Umbuzo ofanele kakhulu wezindawo zokubhukuda eziningi ukufaka ingobo yomlando kwibhokisi eligcwele izici futhi uveze kulowo ohambisanayo uma kudingeka.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa MKV kuya ku MP4?

Ngokuvamile akunjalo. Iningi lezinguquko ligcina umsindo owodwa, owenza ama-channels amaningi (okungukuthi, ukuhlanganisa okuyinhloko), kwenziwe kabusha ukukopela kwe-MP4 container, ngakho-ke umbono kanye ne-alternative-language tracks zilahlekile. AVI, WMV, MPEG, FLV, VOB ne M4V kuya ku-MKV zigcina wonke umsindo, futhi njalo i-MP4 iya MOV. Ukugcina umsindo ohlukile, yenza i-remux ye-MKV ngaleyo track kuqala (i-VLC noma i-ffmpeg ingakwenza lokhu), bese uyiguqula. MP4 yi ISO/IEC 14496-14, ejwayelekile ngo-2001 futhi ivela ku-QuickTime box layout MOV isebenzisa.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa MKV kuya ku MP4?

Kumanye amaqembu. MP4 kuya ku-MOV igcina wonke umbhalo wesihloko esingezansi. AVI, WMV, MPEG, FLV, VOB ne M4V kuya ku-MKV igcina wonke umbhalo wesihloko esingezansi: isihloko sokubhala sikhopiwe noma siguqulwe ku-SRT, futhi isihloko esisekelwe kusithombe njenge-DVD noma i-Blu-ray sikhopiwe njengoba zikhona. MP4, MOV ne WebM kuya ku-MKV igcina kuphela isihloko esingezansi esilandelayo (njengo-ASS), futhi MP4 kuya ku-WebM igcina esilandelayo njenge-WebVTT. Amanye amaqembu, kufaka phakathi i-MKV ukuya ku-MP4 noma i-MOV ne-WebM ukuya ku-MP4, isusa isihloko esingezansi, futhi umguquli awuwabhakisi kusithombe. Isihloko esingezansi esikhona esibhakiwe ehlala, ngoba siyingxenye yefreyimu yevidiyo.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku MKV usuka ku MP4?

MKV yindawo yokugcina eyinhloko kuphela egcina amafayela axhunywe ngokuzenzakalela (izifomethi ze-TTF ze-ASS subs, isithombe sokuzivikela se-JPG, izingeniso ze-PDF eziguqulwe nge-fan). Ukusuka ku-MKV kuya ku-MP4 ushiya lezi zifomethi lapho i-MP4 ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-MKV njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-MP4 ngokuzenzakalela?

Kuxhomekeka ku MP4 isiqoqi. MP4, MOV kanye MKV output ukusebenzisa H.264, okuyinto idlala ku ngempela wonke ifoni, ibrowser kanye TV. WebM output usebenzisa VP9. AVI, WMV kanye MPEG output ukusebenzisa codecs older labo amafomethi akhiwa.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside MKV kuya ku-MP4?

Akukho HDR ukucubungula noma tone mapping. Uma ividiyo ikhophiwe (MKV ku MP4 noma MOV nge default settings), HDR10 idlula njengoba injalo. Uma ividiyo iphinde ikhophiwe, i HDR10 mastering metadata ilahlekile futhi Dolby Vision noma HDR10 + data ayigcinwanga, futhi ngekhwalithi, ukuxazulula noma ifreyimu yesilinganiso sokumiswa ezinye izibini zikhuphula ividiyo kumbala we-8-bit, ngakho i HDR MKV ingabonakalisa i-MP4.

Kungani ihele lami MP4 lincane / likhulu kuna MKV ngemuva kokuguqulwa?

Kuxhomekeka kulokho okwenzekayo kuvidiyo. MKV MP4 noma MOV nge default izilungiselelo ikhophi ividiyo umfutho engashintshiwe, ngakho ubukhulu ihlala eduze komthombo. Ezinye izibini eziningi ziphinde zikhophi: a high-bitrate MKV ngokuvamile ephuma ncane, ngenkathi ekhona kakhulu ecindezelwe eyodwa ingakhula. Ifayela elincane ngaphansi Quality inikeza inzuzo encane, futhi H.265 ku Codec isilungiselelo (MP4, MOV ne MKV) ngokuvamile ncane kuna H.264 ku quality efana kodwa idlala ku amadivayisi ambalwa.
