VOB → MKV

Yebo. i-VOB 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-VOB kuqala kwithuluzi ledesktop njenge HandBrake noma ffmpeg (isihlungi se-yadif). VOB yividiyo equkethwe okutholakalayo kwifolda VIDEO_TS ngayinye ye-DVD — i-MPEG-2 izinhlelo ezihambayo ne-DVD-ekhethekile yokubuka idatha engeziwe.

Hayi, futhi lokhu kuyisizathu esingcono sokushintsha. I VOB iqukethe i-file eyodwa esebenza kahle eyenza ukurekhodwa okude noma okuphezulu kwe-bitrate kuhambe ngokuqondile, okuyinto ebangela ukuthi ukurekhodwa okudala kufike njengengxenye1, ingxenye2, ingxenye3. MKV ayinaso isibopho esifanayo, ngakho ama-pieces angaxhunywa kabusha kwifayela elilodwa eliqhubekayo. VOB ihlukaniswe phakathi kwefayela, ingase ibe CSS-encrypted, futhi ithwale ukuzula iphakethe elikhohlisa abadlali abadingayo.

Kuyinto evamile kakhulu i-DRM. Ezinye VOB 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.

Kungenzeka ukuthi ayisebenzi. VOB 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, VOB luyi-container ephephile yokuhlala kuyo. MKV ayikho ngaphezu kwe-hardware yendawo yosizo — amafoni, iziphequluli ne TVs ngokuvamile udinga VLC noma remux ngaphambi kokuba badlala.

Noma yini ofuna ukuyigcina, yebo. VOB 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. I-MKV iyindawo yokugcina ekhethiwe ngoba igcina imisindo engaphelelanga, izihloko ezilula, izihloko eziphawulekayo kanye nezithombe zobuso kwifayela elilodwa.

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-VOB 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-VOB kuya ku-MKV ushiya lezi zifomethi lapho i-MKV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-VOB 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.

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 VOB ingabonakalisa i-MKV.
