MP4 kuya MKV Imibuzo Evame Ukubuzwa Yokuguqulwa

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

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

Ingabe i-MKV ingagcina ama-tracks omsindo angaphezu kwesinye?

Yebo, futhi kuyithuthukiso eliyiqiniso ku MP4. MKV iphatha wonke umsindo njengohlelo oluhle, ngakho-ke umsindo ovela ku-language, i-dub kanye nombhali we-comment ungahlala kuhele olulodwa nomdlalo oshintsha phakathi kwazo uma kudingeka. I-MKV iyindawo yokugcina ekhethiwe ngoba igcina imisindo engaphelelanga, izihloko ezilula, izihloko eziphawulekayo kanye nezithombe zobuso kwifayela elilodwa.

Ingabe MKV isekela izibonisi zesiqephu ezi MP4 azisebenzisi?

Ikwenza. i-MKV igcina amasigaba njenge-metadata yebhokisi, ngakho ukurekhoda okude kungafinyelelwa ngengxenye endaweni yokuhlanza ibha yokuqhubekela phambili. i-MP4 ayinaso isikhala sokubeka le lwazi, ngakho i-MKV eguqulwe iqala ngaphandle kwamasigaba; yongeza izibonisi ngemuva ngethuluzi njenge-MKVToolNix noma i-ffmpeg.

Ingabe ngingakwazi ukuxhuma ihele kwikhasi le-web ngemuva kokushintsha MP4 kuya ku MKV?

Akunakuqondile. MP4 idlala ngaphakathi kwelayini ngayinye yesiphequluli; MKV ayisebenzi, ngakho ikhasi elifakazelayo libuyela emuva ku-download link noma ku-player frame engenanto. Uma ihele lizosetshenziswa kwi-website, gcina i-MP4 kwi-web futhi uthathe i-MKV njenge-archive noma uhlela ikhophi. MKV ayikho ngaphezu kwe-hardware yendawo yosizo — amafoni, iziphequluli ne TVs ngokuvamile udinga VLC noma remux ngaphambi kokuba badlala.

Ingabe i-MKV izodlala ngokulula ku-smartphone noma ku-TV?

Kungenzeka ukuthi ayisebenzi. MP4 i-decoded yi-silicon ekhethekile kumafoni, ama-tablets nama-TV, ngakho-ke idlala ngaphandle kokucindezela ibhethri. MKV ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, MP4 luyi-container ephephile yokuhlala kuyo.

Zonke MP4 ne MKV 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. MP4 yindawo ephephile yokufinyelela ekhona — yonke ifoni, i-browser, i-console, umhleli ne-Smart TV eyenziwe eminyakeni eyisithupha edlule idlala ngaphandle kwesoftware engeziwe.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa MP4 kuya ku MKV?

Ngokuvamile akunjalo. Iningi lezinguquko ligcina umsindo owodwa, owenza ama-channels amaningi (okungukuthi, ukuhlanganisa okuyinhloko), kwenziwe kabusha ukukopela kwe-MKV 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-MP4 ngaleyo track kuqala (i-VLC noma i-ffmpeg ingakwenza lokhu), bese uyiguqula. I-MKV yi-Matroska, ibhokisi elivulekile elihlolwe ngo-2002 ngaphandle kokwenqaba kwelayisense futhi akukho phezulu okwazi ukuwugcina.

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

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 MP4 usuka ku MKV?

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-MP4 kuya ku-MKV ushiya lezi zifomethi lapho i-MKV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-MP4 njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-MKV ngokuzenzakalela?

Kuxhomekeka ku MKV 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 MP4 kuya ku-MKV?

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 MP4 ingabonakalisa i-MKV.
