VOB kuya M4V Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani i-VOB ku-M4V ngaphandle kokulahlekelwa yikhwalithi yevidiyo?

Layisha phezulu ihele lakho VOB futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless M4V output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / ubunjani obuphezulu). I-codec ikhethiwe ukufana ne M4V container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. I-VOB iqukethe i-MPEG-2 video, AC-3 noma umsindo we-PCM, kanye ne-DVD subpicture subtitle streams, ihlukaniswe ibe yi-1 GB segments yi-DVD spec. Ukuthuthukiswa M4V MP4 - H.264 noma HEVC nge AAC - nge optional Apple FairPlay DRM ne iTunes isiqephu metadata.

I-VOB yami ibonisa ama-comb lines ekuhambeni - ngabe lokhu kuzodluliselwa ku-M4V?

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi VOB 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-M4V. VOB yividiyo equkethwe okutholakalayo kwifolda VIDEO_TS ngayinye ye-DVD — i-MPEG-2 izinhlelo ezihambayo ne-DVD-ekhethekile yokubuka idatha engeziwe.

I-VOB yami yokurekhoda ihlukaniswe ibe yizingxenye ezinombhalo - i M4V inezinga elifanayo?

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. M4V 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.

Kungani ihele lami VOB lingakwazi ukushintsha ku M4V?

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.

Ingabe kufanelekile ukushintsha ama-VOB ama-records adala ku-M4V?

Noma yini ofuna ukuyigcina, yebo. VOB ihlobene nohlobo oludlule lwevidiyo nesoftware efunda ngayo ihlala ihamba ihamba isuka kumafoni, iziphequluli nezinhlelo zokusebenza. Ukusuka kwevidiyo ku M4V manje, uma umqokeli ohlanzekile ukhona, kuyinto ehlukile phakathi kwegobo lomlando ongavula ngawo iminyaka eyisithupha nenye ongayenza. I-M4V igcina izibonisi zesigaba, umsebenzi wobuciko kanye nezingcingo zesihloko esingezansi ngendlela i-Apple TV app elindele ngayo, okujwayelekile MP4 kuvame ukulahlekelwa.

Yini i-codec yevidiyo i M4V isebenzisa?

Kuxhomekeka ku M4V isihlungi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhurawuza, nama-Smart TVs. MKV iphutha ku-H.265 / HEVC ukuze kube nengxenye yobukhulu befayela ngekhwalithi elinganayo. WebM iphutha ku-VP9. Izinketho eziphezulu zibonisa ngokucacile ukhetho lwe-codec uma ufuna ukucima. M4V Apple's uhlobo MP4, esetshenziswa iTunes kanye Apple TV app for movies kanye TV iziqephu.

Ingabe umsindo wami uzophila ukuguqulwa VOB kuya ku M4V?

Yebo. Uma VOB ne M4V zihlanganisa i-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka ikhowudi — okufanayo. Uma ama-codecs ahlukile, umsindo uguqulwa ube yi-AAC / Opus / Vorbis ngokuya ngomsebenzi oxhaswa yi-M4V. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula VOB ku M4V?

Ngokungagqibekanga yebo — i-24fps VOB ihlala i-24fps ku-M4V; i-60fps VOB ihlala i-60fps. Uma ufuna ukuguqula isilinganiso (isibonelo, interlaced 29.97 → progressive 30, noma 60 → 30 ukulayisha amaphesenti), isinqumo se-framerate siphatha 3:2 ukukhishwa, ukususwa kwe-interlacing, kanye nokuhlanganisa ifreyimu ku-encoding pass.

Ingabe ubukhulu behele bushintsha kanjani kusuka ku VOB kuya ku M4V?

Same-codec re-mux (VOB H.264 → M4V H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 ngokuvamile uhlukanisa ihele ngengxenye ngekhwalithi efanayo yokubuka; VP9 ifana kakhulu; AV1 ihlukanisa ezinye i-20-30% kodwa ihamba kancane uku-encode.

Ingabe ihele M4V lidlalwa ku-iPhone, Android, ne-Smart TVs?

MP4 / H.264 idlala ngokusemthethweni kuwo wonke amadivayisi amanje. MOV / H.264 idlala kumadivayisi we-Apple nakwamanye ama-TV kodwa hhayi njalo kuma-Android adala. MKV idinga i-VLC ku-iOS. I-WebM iyisiphequluli-kuqala. Izinketho ezithuthukisiwe zifaka phakathi "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-M4V codec / ibhokisi eliphephile lenjongo yakho. DRM-ikhuselwe M4V ukuthenga ngeke kushintshwe yinoma yini; kuphela M4V izithombe ezingakhuselwanga ziguqulwe, futhi abadlali Apple-ayikho njalo kufanele ubanzi kuthiwa.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-VOB yevidiyo yehora elilodwa ibe yi-M4V?

I-same-codec re-mux ifinyelela ngokushesha — imizuzwana engu-30 kuya ku-60 yehele lehora elilodwa. I-codec egcwele isebenza ngokuyisisekelo 0.3-0.7x isikhathi somthombo ku-GPU pipeline yethu, ngakho-ke i-1-hour VOB → M4V iphele ngemizuzu engu-18-40 ngokuya ngesinqumo ne-codec ethengiswayo.

Yini isixazululo esiphezulu esixhaswe yi VOB kuya ku M4V?

Kuze ku-8K (7680×4320) kuma-premium plans. Ukuguquka okumahhala kufinyelela ku-4K (3840×2160) ngobukhulu befayela ngalinye. I-HDR metadata (HDR10, HDR10+, Dolby Vision uma ikhona) idluliselwa lapho ama-VOB ne-M4V amabhokisi axhasa khona.
