AVI kuya MP4 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-AVI ibe yi-MP4 ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Uma ama-AVI ne-MP4 amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-MP4 ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB AVI ku-MP4 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. Kuyinto encane kakhulu ukuthi wonke ama-MP4 aphilayo ayizividiyo ze-H.264 ezinesandi se-AAC; isiqoqi sigcina ngokusemthethweni i-HEVC, AV1 ne-VP9.

I-AVI yami ibonisa ama-comb lines ekuhambeni - ngabe lokhu kuzodluliselwa ku-MP4?

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-MP4. 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 MP4 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. MP4 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 MP4?

Yebo. AVI ayinaso isikhala esisetshenziswayo sesihloko esincane, ngakho isikhala sesihloko se AVI kufanele sifakwe kusithombe noma sithunyelwe njengefayela le-sidecar elilodwa. MP4 sifaka isikhala sesihloko njenge-stream ekhethiwe, ngakho ngemuva kokuguqulwa ungafaka isikhala se-SRT okubonayo angashintsha, ashintshe noma aphinde ashintshe.

I AVI yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe MP4?

Akunakuthembeka. AVI igcina imisindo eminingi njengezingoma zohlobo lokuqala, kodwa MP4 uxhaso lokudlala ngaphezu kwengoma yokuqala akulingani, ngakho abadlali abaningi bazoveza kuphela eyodwa. Khetha ingoma oyifunayo ngaphambi kokuguqula; abanye bakhishwa kahle kumafayela abo ngaphezu kokushiya emgodini ofihlayo. AVI ilula kakhulu, okuyinto ngokucacile kungani ama-camcorders akudala, amakhadi okuqoqa, DVD amathuluzi okukhishwayo kanye Windows-era software wonke akhona akhipha. I-MP4 isekela kuphela ifomu elilodwa lesihloko esihlonishwa kakhulu (mov_text), futhi umsindo we-multi-track awuthembeki ngaphandle kwama-players wedesktop.

Ingabe i-MP4 izodlala kwi-browser uma i-AVI ingadlalanga?

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I AVI efakwe kwikhasi lewebhu ibonisa umdlali okhubazekile noma icindezela ukulayisha, ngoba iziphequluli azikho izikhombisi ezizo. MP4 idlala ngaphakathi ngengxenye yevidiyo ye-HTML5 engavamile ngaphandle kweplugin noma kusetshenziswa okungaphandle. MP4 yindawo ephephile yokufinyelela ekhona — yonke ifoni, i-browser, i-console, umhleli ne-Smart TV eyenziwe eminyakeni eyisithupha edlule idlala ngaphandle kwesoftware engeziwe.

Ingabe kufanelekile ukushintsha ama-AVI ama-records adala ku-MP4?

Noma yini ofuna ukuyigcina, yebo. AVI ihlobene nohlobo oludlule lwevidiyo nesoftware efunda ngayo ihlala ihamba ihamba isuka kumafoni, iziphequluli nezinhlelo zokusebenza. Ukusuka kwevidiyo ku MP4 manje, uma umqokeli ohlanzekile ukhona, kuyinto ehlukile phakathi kwegobo lomlando ongavula ngawo iminyaka eyisithupha nenye ongayenza.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa AVI kuya ku MP4?

Yebo — wonke umculo ohambayo ku AVI (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku MP4 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. MP4 yi ISO/IEC 14496-14, ejwayelekile ngo-2001 futhi ivela ku-QuickTime box layout MOV isebenzisa.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa AVI kuya ku MP4?

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho MP4 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 MP4 igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka AVI no MP4 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-MP4 kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku AVI usuka ku MP4?

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-MP4 ushiya lezi zifomethi lapho i-MP4 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-MP4 ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne MP4 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.
