WMV → MKV

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi WMV okuqukethwe kuvame ukuxhunywa ngoba ifomu livela esikhathi sokusabalalisa ne-DVD. Amafreyimu axhunywe agcina ama-fields amabili aphakathi nendawo aphezulu athathwe ngengxenye yesihlanu yesibili; kufoni noma kumboniso oqhubekayo-oqhubekayo ofunda njenge-horizontal combing nganoma yini ehambayo. Vula ukhetho lokuxhunyaniswa futhi umbhalo-mqoka uxhuma ama-fields kuwo wonke ama-frames aqhubekayo ngaphambi kokubhala i-MKV. WMV Windows Media Video, Microsoft ASF-based format kusuka Windows XP isikhathi.

Yebo. WMV ayinaso isikhala esisetshenziswayo sesihloko esincane, ngakho isikhala sesihloko se WMV kufanele sifakwe kusithombe noma sithunyelwe njengefayela le-sidecar elilodwa. MKV sifaka isikhala sesihloko njenge-stream ekhethiwe, ngakho ngemuva kokuguqulwa ungafaka isikhala se-SRT okubonayo angashintsha, ashintshe noma aphinde ashintshe.

Yebo, futhi kuyithuthukiso eliyiqiniso ku WMV. 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.

Ikwenza. MKV igcina amasigaba njengedatha ye-meta eqoqayo, ngakho ukurekhodwa okude kungafinyelelwa ngengxenye endaweni yokuhlanza ibha yokuqhubekela phambili. WMV ayikho indawo yokubeka lo lwazi, ngakho uma umsuka uthunyelwe ngohlu lwesigaba, kwakuyihele le-sidecar — nikela ngalo ku-converter futhi libhalwe ku-MKV.

Kuyinto evamile kakhulu i-DRM. Ezinye WMV izithombe zibhalwe ngokufihlakele ku-bitstream level yisitolo noma isofthiwe eyenza, futhi isithombe esibhalwe ngokufihlakele asikwazi ukucinywa yithu noma yinoma yini ngaphandle kwesitshixo selayisense. Izithombe ongazirekhodile, ozenzayo noma ozibhumele ngaphandle azikhuselwanga ziguqulwa ngokuvamile; ukuthenga okusemthethweni akuzokwenza, futhi akukho oguqulelayo angaba nesiqiniseko sokuthi kungashintshwa. WMV ngokuphumelelayo iphele efile: macOS, iOS, Android kanye nesipiliyoni ngasinye idinga isithathu-party decoders, futhi ezinye WMV amafayela zithwala DRM ukuthi akufanele kushintshwe ngaso sonke isikhathi.

Noma yini ofuna ukuyigcina, yebo. WMV ihlobene nohlobo oludlule lwevidiyo nesoftware efunda ngayo ihlala ihamba ihamba isuka kumafoni, iziphequluli nezinhlelo zokusebenza. Ukusuka kwevidiyo ku MKV manje, uma umqokeli ohlanzekile ukhona, kuyinto ehlukile phakathi kwegobo lomlando ongavula ngawo iminyaka eyisithupha nenye ongayenza.

Yebo — wonke umculo ohambayo ku WMV (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku MKV lapho isiqoqi esizosiza umsindo ohambayo oningi. MKV ne MOV ziphatha umculo ohambayo ongenasiphelo; MP4 isekela abaningi kodwa abanye abadlali behardware babona umculo 1 kuphela; WebM iphele ku-Opus / Vorbis umculo owodwa. I-MKV yi-Matroska, ibhokisi elivulekile elihlolwe ngo-2002 ngaphandle kokwenqaba kwelayisense futhi akukho phezulu okwazi ukuwugcina.

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho MKV zingazithwala: MKV igcina i-SRT, ASS, SSA, PGS, VobSub ngokusemthethweni; MP4 igcina kuphela i-mov_text (ifomethi ephukile). Ukushintsha MKV nge-ASS styled subs ku-MP4 kuzozikhuphula zibe yi-mov_text noma zizicwebezele. Izihloko ezinzima (zicwebezelelwe kwividiyo) zithwale ngaphandle kokungabaza.

Isigaba se-metadata sidlulisa phakathi kuka WMV no MKV lapho izihlungi zombili zixhasa isiqephu se-atomi (MKV, MP4, MOV). I-WebM igcina iziqephu kwi-Matroska-compatible block, ngakho-ke i-MKV <-> isigaba se-WebM sihamba ngokuhlanzekile. I-AVI ayinasiqephu esicacisiwe, ngakho-ke ukushintsha i-AVI ibe yi-MKV kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

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

I-codec ejwayelekile ikhethiwe ukufana ne MKV isitoreji ngokuzithandela: MKV ikhetha i-H.265 (HEVC) ukucindezela okuhle; MP4 ikhetha i-H.264 ukuxhasa isisetshenziswa esibanzi; WebM ikhetha i-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ethuthukisiwe engezansi — AV1 itholakala ku-MKV / WebM lapho ufuna khona ukucindezela okuphezulu futhi ungalindela ukucindezela. MKV ayikho ngaphezu kwe-hardware yendawo yosizo — amafoni, iziphequluli ne TVs ngokuvamile udinga VLC noma remux ngaphambi kokuba badlala.
