DivX kuya MP4 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi DivX ku MP4 ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Layisha phezulu ifayela lakho DivX futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless MP4 output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / umgangatho ophezulu). I-codec ikhethiwe ukufana ne-MP4 container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. Isihloko seDivX yi-MPEG-4 Part 2 video, sivame ukuboshwa ku-AVI, nge-MP3 noma AC-3 umsindo ohambisana nayo. Kuyinto encane kakhulu ukuthi wonke ama-MP4 aphilayo ayizividiyo ze-H.264 ezinesandi se-AAC; isiqukathi sigcina ngokusemthethweni i-HEVC, AV1 ne-VP9.

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

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi DivX 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. I-DivX ibiza i-codec hhayi ibhokisi — i-MPEG-4 Part 2 isebenzisa i-DVD eyisikhashana ku-CD eyodwa ekhona ngo-1999.

I-DivX yami yokurekhoda ihlukaniswe ibe yizingxenye ezinomkhawulo - ngabe i-MP4 inesimo esifanayo?

Hayi, futhi lokhu kuyisizathu esingcono sokushintsha. I DivX 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-DivX idinga i-bitrate ephindwe kabili kune-H.264 ukuze ikwazi ukukhiqiza ngekhwalithi efanayo futhi ayinakho indlela ye-HDR, 10-bit umbala noma izixazululo ezingaphezu kwe-1080p.

Ingabe ngizongeza izihloko ezikhethiwe uma ifayela liyi MP4?

Yebo. DivX ayinaso isikhala esisetshenziswayo sesihloko esilula, ngakho isikhala sesihloko se DivX 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 DivX yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe MP4?

Akunakuthembeka. DivX 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. Ama-DVD aqinisekisiwe yi-DivX adlalayo ahlala ejwayelekile, futhi i-codec ihlala i-floor ehambisanayo yohlobo oluphelele lwe-set-top hardware. 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-DivX ingadlalanga?

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I DivX 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 iyinjongo ephephile yokulethwa - yonke ifoni, i-browser, i-console, umhleli ne-Smart TV eyenziwe eminyakeni eyisithupha edlule idlala ngaphandle kwesoftware engeziwe.

Ingabe MP4 iyibhokisi noma i-codec, futhi ngabe lokhu kushintsha lokho engikutholayo emuva?

Ishintsha ukuthi yini ongayilindele kuhele lwesingeniso. Ingxenye eyodwa yokuguqulwa ibizwa ngokuthi ukungenisa ngaphandle, hhayi ukupakisha, ngakho lokho okubuyayo ukuthi i-bitstream ngaphakathi kwebhokisi elifanele kakhulu — ngokuvamile MP4 noma MKV. Uhlelo lubonisa ibhokisi; i-codec yilokho okusho ubukhulu befayela futhi lapho izodlala khona.

Yini i-codec yevidiyo i MP4 isebenzisa?

Kuxhomekeka ku MP4 isiqoqi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhuleki, nama-Smart TVs. MKV iphutha ku-H.265 / HEVC ukuze kufinyelelwe isigamu sesayizi yefayela ngekhwalithi elinganayo. WebM iphutha ku-VP9. Izinketho ezithuthukisiwe zibonisa ukhetho lwe-codec olucacile uma ufuna ukucima. MP4 yi ISO/IEC 14496-14, ejwayelekile ngo-2001 futhi ivela ku-QuickTime box layout MOV isebenzisa.

Ingabe umsindo wami uzohlala ukhona DivX kuya ku MP4?

Yebo. Uma DivX ne MP4 bebelana nge-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka uphawu — okufanayo. Uma ama-codecs ahluka, umsindo uguqulwa ku-AAC / Opus / Vorbis ngokuya ngoMP4 ibhokisi lokusekela. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula DivX ku MP4?

Ngokungajwayelekile yebo — i-24fps DivX ihlala i-24fps ku-MP4; i-60fps DivX ihlala i-60fps. Uma ufuna ukuguqula isilinganiso (isibonelo, i-interlaced 29.97 → progressive 30, noma i-60 → 30 uku-upload amalimi), isinqumo se-framerate siphatha 3:2 uku-pulldown, deinterlacing, ne-frame-blending ku-code pass efanayo.

Ingabe ubukhulu befayela bushintsha kanjani kusuka ku DivX kuya ku MP4?

Same-codec re-mux (DivX H.264 → MP4 H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 kufaka ihele ngengxenye ngaleyo khwalithi yokubuka efanayo; VP9 ifana kakhulu; AV1 ihlukanisa ezinye 20-30% kodwa ihamba kancane ukukopela.

Ingabe ihele MP4 lizodlala ku-iPhone, Android, ne-Smart TVs?

MP4 / H.264 idlala ngokusemthethweni kuwo wonke amadivayisi amanje. MOV / H.264 idlala kumadivayisi we-Apple namanye ama-TV kodwa ahlala e-Android edlule. I-MKV idinga i-VLC ku-iOS. I-WebM iyisiphequluli sokuqala. Izinketho ezithuthukisiwe zifaka "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-MP4 codec / ibhokisi eliphephile kakhulu lenjongo yakho.
