WMV → MKV

Yebo. i-WMV iqukethwe ngokuvamile i-interlaced, ngoba ifomu livela esikhathini sokusabalalisa ne-DVD, futhi lesi siguquli asinayo inketho yokususa ukuxhumana, ngakho-ke ukuxhuma ku-MKV. Uma kubaluleke, susa ukuxhumana kwe-WMV kuqala kwithuluzi ledesktop njenge HandBrake noma ffmpeg (isihlungi se-yadif). 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. i-MKV igcina amasigaba njenge-metadata yebhokisi, ngakho ukurekhoda okude kungafinyelelwa ngengxenye endaweni yokuhlanza ibha yokuqhubekela phambili. i-WMV ayinaso isikhala sokubeka le lwazi, ngakho i-MKV eguqulwe iqala ngaphandle kwamasigaba; yongeza izibonisi ngemuva ngethuluzi njenge-MKVToolNix noma i-ffmpeg.

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.

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-WMV 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.

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.

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.

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. MKV ayikho ngaphezu kwe-hardware yendawo yosizo — amafoni, iziphequluli ne TVs ngokuvamile udinga VLC noma remux ngaphambi kokuba badlala.
