AVI kuya M4V Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-AVI ibe yi-M4V ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Uma ama-AVI ne-M4V amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-M4V ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB AVI ku-M4V ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. Amafayela we-AVI adlule ama-codecs amanje: cabanga i-MPEG-4 Part 2 (DivX/Xvid), Motion JPEG noma amafreyimu amnyama angacindezelwa ngaphandle kwe-H.264. Ukuthuthukiswa M4V MP4 - H.264 noma HEVC nge AAC - nge optional Apple FairPlay DRM ne iTunes isiqephu metadata.

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

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi AVI 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. AVI Microsoft Audio Video Interleave, isungulwe ngo-1992 phezu RIFF chunk format - eyodwa yezinto eziphilayo ezidala kakhulu okwamanje e circulation.

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

Hayi, futhi lokhu kuyisizathu esingcono sokushintsha. I AVI 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. I-AVI ayinaso isixhaso esisemthethweni se-codecs yamanje, isilinganiso sefreyimu esiguqukayo, izihloko ezithambile noma amafayela angaphezu kuka-4 GB ngaphandle kokuhlaselwa, futhi i-chunk ngayinye i-overhead ibhoboza ifayela.

Ingabe ngizongeza izihloko ezikhethiwe uma ifayela liyi M4V?

Yebo. AVI ayinaso isikhala esisetshenziswayo sesihloko esincane, ngakho isikhala sesihloko se AVI kufanele sifakwe kusithombe noma sithunyelwe njengefayela le-sidecar elilodwa. M4V sifaka isikhala sesihloko njenge-stream ekhethiwe, ngakho ngemuva kokuguqulwa ungafaka isikhala se-SRT okubonayo angashintsha, ashintshe noma aphinde ashintshe.

Ingabe M4V isekela izibonisi zesiqephu ezi AVI azisebenzisi?

Ikwenza. M4V igcina amasigaba njengedatha ye-meta eqoqayo, ngakho ukurekhodwa okude kungafinyelelwa ngengxenye endaweni yokuhlanza ibha yokuqhubekela phambili. AVI ayikho indawo yokubeka lo lwazi, ngakho uma umsuka uthunyelwe ngohlu lwesigaba, kwakuyihele le-sidecar — nikela ngalo ku-converter futhi libhalwe ku-M4V. I-M4V igcina izibonisi zesigaba, umsebenzi wobuciko kanye nezingcingo zesihloko esingezansi ngendlela i-Apple TV app elindele ngayo, okujwayelekile MP4 kuvame ukulahlekelwa.

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

Noma yini ofuna ukuyigcina, yebo. AVI 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.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa AVI kuya ku M4V?

Yebo — wonke umculo ohambayo ku AVI (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku M4V 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. M4V Apple's uhlobo MP4, esetshenziswa iTunes kanye Apple TV app for movies kanye TV iziqephu.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa AVI kuya ku M4V?

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho M4V 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.

Ingabe AVI kuya ku M4V igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka AVI no M4V 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-M4V kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku AVI usuka ku M4V?

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-AVI kuya ku-M4V ushiya lezi zifomethi lapho i-M4V ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-AVI njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-M4V ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne M4V 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. DRM-ikhuselwe M4V ukuthenga ngeke kushintshwe yinoma yini; kuphela M4V izithombe ezingakhuselwanga ziguqulwe, futhi abadlali Apple-ayikho njalo kufanele ubanzi kuthiwa.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside AVI kuya ku-M4V?

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-M4V uma izihlungi zombili ne-codec ekhethiwe ziyixhasa (HEVC, AV1 ku-MKV / MP4). I-Dolby Vision inamandla kakhulu — i-DV profile 5 / 7 / 8.1 ku-AVI ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-M4V isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.
