MP4 Amathuluzi

Guqula MP4 kuya futhi kusuka kumafomethi ahlukahlukene

Mayelana MP4

Ifomethi yesitsha se-MP4 ingagcina ividiyo, umsindo, imibhalo engezansi, nezithombe kufayela elilodwa ngokucindezela okuhle kakhulu.

MP4 Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele MP4?

I-MP4 (i-MPEG-4 Ingxenye 14) iyifomethi yesitsha semidiya yedijithali yokugcina ividiyo, umsindo, kanye nemibhalo engezansi.

Kungani wonke amasayithi nesistimu ecela i-MP4 ngokukhethekile?

MP4 yi ISO standard hhayi i-format ye-vendor, hardware decoders for its usual payload ship in every phone, console, browser and television sold in the last decade, and every editor and upload form accepts it. Nothing else has that reach, which is why MP4 is the sensible default output for anything that has to simply work. MP4 yindawo ephephile yokufinyelela ekhona — yonke ifoni, i-browser, i-console, umhleli ne-Smart TV eyenziwe eminyakeni eyisithupha edlule idlala ngaphandle kwesoftware engeziwe.

Kungani ifoni yami igcina konke njenge MP4?

Ngenxa yokuthi i-handset ikhonjiswa kunoma yini i-chip yayo eyenza kwi-hardware, futhi MP4 yilokho okuhlelwe i-silicon. Ikhamera i-app ayibuzanga — ibhala ifomu elisetshenziswa lingakhiqiza ngaphandle kokulahleka noma ukufudumeza, okungaba yifomethi edinga ukukhishwa noma yini. Ukushintsha ngemuva kujwayelekile futhi akudingi lutho kukhwalithi uma okuhloswe ngalo kugcina i-payload efanayo. MP4 yi ISO/IEC 14496-14, ejwayelekile ngo-2001 futhi ivela ku-QuickTime box layout MOV isebenzisa.

Ingabe ngidlala MP4 ku-tab yesiphequluli ngaphandle kokufaka noma yini?

Yebo — MP4 yisinye sezifomethi zevidiyo ezincane ezixhunywe ku-browser, ngakho-ke ukushaya ifayela kwi-tab noma ukulifaka kukhasi kusebenza kuphela kudesktop neselula. Lokhu kwenza kube yisinqumo esifanele sokudlalwa okuzenzakalelayo kwekhasi lewebhu, futhi yisizathu sokuguqulwa kulolu hlobo lwefayela kuvame ukuxazululwa ngokushesha "ividiyo ayizodlala kuwebhusayithi yami".

Ingabe izihloko ezingezansi ngaphakathi kwe MP4 zingakhethwa, noma ziboshwe ngaphakathi kwesithombe?

Kukhethwa, uma kufakwe kahle. MP4 ifaka izihloko ezingezansi njengemithombo yabo ehlukile engezansi kwevidiyo, ngakho-ke umbukeli angashintsha ulwimi, azicishe, noma aphinde aphinde asebenzise izihloko ezingezansi kumdlali oxhasa lokhu. Izihloko ezingezansi ezibomvu zingasetshenziswa — ziyi-pixels kuphela kwifreyimu — kodwa zihlala njalo, futhi kungekho sizathu sokukhetha uma isiqukathi sixhasa into engokoqobo.

Kungani i-audio track eyodwa kuphela ehlala e MP4 yami?

Ngenxa yokuthi lokhu konke ifomu liyithatha ngokunethezeka. Izinhlamvu zomsindo ezingeziwe zingabhalwa ku MP4, kodwa ukuxhaswa kokudlala ngemuva kokuqala akulingani kahle kakhulu ukuthi amathuluzi amaningi agcina kuphela elinye futhi asuse ezinye. Uma umsuka unesihloko noma ulwimi lwesibili, khipha lezi ukuze uhlukanise amafayela omsindo ngaphandle kokuthembela kuwo kubhokisi elifihlayo. I-MP4 isekela kuphela ifomu elilodwa lesihloko esihlonishwa kakhulu (mov_text), futhi umsindo we-multi-track awuthembeki ngaphandle kwama-players wedesktop.

Ingabe ukusebenzisa MP4 kuthatha ilayisense lepatenti?

Akunakho okukudingayo. Ama-codecs ahlobene ahlobene ne-patent pools, futhi ilayisense libekwe ngabantu abathumela ama-decoders — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ihele lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware futhi kungani ama-royalty-free alternatives akhona, futhi ashintshanga noma yini mayelana nokushintsha ifayela oline.

Ingabe ngingenza ngiphinde ngibize isiqephu endaweni yokushintsha MP4?

Kunzima kakhulu, futhi kufanelekile ukuqonda ukuthi kungani: isithonjana siyisihloko, ngenkathi ama-bytes ngaphakathi kufakwe ngefomethi eyodwa ekhethekile. Ukushintsha igama kwenza ihele igama lakhe lithembisa okuthile okuqukethwe kwayo akusho ukunikela, futhi noma yini evula ihele noma liyiphoqa noma liyifunda kabi. Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda uphinde

Ingabe ngiguqula isibaya esigcwele se MP4 amafayela ngasikhathi sinye?

Nge-akhawunti, yebo — khiphana ndawonye futhi zibekwe njengemisebenzi eyodwa endaweni yokuphathwa ngayinye ngasikhathi sinye, ngezinhlelo ezifanayo ezisetshenziswa ngaphesheya kweqembu futhi izimpendulo zibuyiselwe ndawonye. Ukuguquka okumahhala kusebenza ihele elilodwa ngasikhathi sinye (amathuluzi okuxhuma athatha amabini); i-plan ekhokhelwa yilokho okuvulela ukuqhubekela phambili kweqembu kanye nobukhulu bomgwaqo wefayela ngalinye, okukwenza ukuguquka kwehele lonke le-archive kube lula.

Yini ezoba nehele lami MP4 ngemuva kokuguqulwa?

Kususwa. Ukulayisha kanye nemiphumela eguqulwe zombili zihlala kumhlinzeki kuphela uma umsebenzi ufuna futhi zisuswa ngokuzenzakalela; ukudluliswa kuhamba nge HTTPS emigwaqweni emibini. Akukho muntu ofunda okuqukethwe, akukho okuhlobene, futhi akukho okudluliswa kunoma ubani. Uma ufuna ukuyeka ukulindela ukuhlanzwa okuzenzakalelayo, ukuvala umsebenzi kuzosusa amafayela ngokushesha.

Ingabe ukuguqula i-MP4 kuzothatha isikhathi esingakanani?

Ngokuvamile amasekondi. Amafayela amancane asebenza ngokushesha, futhi izimo ezithatha isikhathi esingokoqobo ziyizinto ezisebenza umsebenzi ongokoqobo: ukurekhodwa okude okudinga ukuphinde kubhalwe ifreyimu ngefreyimu, idokhumende elixhunywe lihamba nge-character recognition, noma iqembu elikhulu kakhulu. lapho ukuguqulwa kuphinde kuphinde kuhlanganise noma kuphinde kuhlanganise idatha ekhona ihlala ngokushesha kungakhathaliseki ukuthi ifile ikhulu kangakanani, ngoba akukho okuzokhishwa.

Ingabe ngidinga i-akhawunti ukuguqula i-MP4?

Akuna. Thola ifayela ngaphakathi, khetha ifomu lokuphuma, futhi ulayishe imiphumela — akukho ukubhalisa, akukho i-imeyili, akukho uphawu lwamanzi kulokho okubuyayo. I-akhawunti ikhona ngezinsiza ezidinga enye: umkhawulo omkhulu wefayela ngalinye, ukuguqula amafayela amaningi ngasikhathi sinye endaweni yesinye ngesikhathi, kanye nembali yemisebenzi yakho yamanje.
