MP4 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili MP4?

I-MP4 (i-MPEG-4 Icandelo 14) yifomathi yesikhongozeli semidiya yedijithali yokugcina ividiyo, iaudio, kunye nemibhalo engezantsi.

Kutheni iwebhusayithi nganye nesixhobo sicela i-MP4 ngokukodwa?

Kuba yifomati enye ethe yavuma kuyo yonke ishishini. MP4 yi ISO eqhelekileyo kunokuba yifomati yomthengisi, i-hardware i-decoders ye-payload yayo eqhelekileyo ehamba nganye ifowuni, console, umkhangeli zincwadi kunye netelevisi ethengisiweyo kwiminyaka elishumi edlulileyo, kwaye wonke umhleli kunye nokukhuphela ifomu iyamkela. Akukho nto enye ekhoyo, nto leyo ibangela i MP4 ibe yimveliso emiselweyo efanelekileyo yento efuna ukuba isebenze ngokulula. I-MP4 yindawo ekhuselekileyo yokunikezelwa kweenkqubo ezifumanekayo - yonke ifowuni, ibrowser, i-console, umhleli kunye neSmart TV eyenziwe kwiminyaka elishumi edlulileyo idlala ngaphandle kwesoftware engaphezulu.

Kutheni le nto ifowuni yam igcina konke njenge MP4?

Kuba isixhobo sefowuni sikhowudisa nantoni na ichip yayo eyenza kwihardware, kwaye MP4 yiyo loo silicon yakhiwa kuyo. Inkqubo yekhamera ayifuni umbuzo - ibhala ifomati yesixhobo esikwaziyo ukuvelisa ngaphandle kokucinezela okanye ukufudumeza, ekufunekanga ifomati nantoni na enye efuna ukufumana. Ukutshintsha emva koko kuqhelekileyo kwaye akubiza nto kwixabiso xa injongo igcina umthwalo ofanayo. I-MP4 yi-ISO/IEC 14496-14, imiselwe ngo-2001 kwaye ivela kwibhokisi yobeko lwe-QuickTime efanayo ne-MOV esetyenziswa.

Ndingadlala i MP4 kwi-tab yesikhangeli ngaphandle kokufakela nantoni na?

Ewe - MP4 yenye yezona zininzi zefomati zevidiyo ezisebenzisa ikhowudi yendawo, ngoko ukurhoxisa ifayile kwi tab okanye ukudibanisa kwiphepha lisebenza kwi desktop kunye nefowuni ephathekayo. Oku kwenza ukuba kube lukhetho olufanelekileyo lwento ekufuneka idlala kwilayini kwiphepha le web, kwaye yisizathu sokuguqula kolu hlobo luyakuba lugqibo olukhawulezayo lwe "ividiyo ayizukudlala kwiwebhusayithi yam".

Ingaba izihloko ezingaphantsi ngaphakathi kwe MP4 zikhethwa, okanye zitshiswe kumfanekiso?

Iyakhethwa, ukuba yafakwa kakuhle. MP4 ithatha izihloko zesiphelo njengemijelo yabo ekhethekileyo ecaleni kwevidiyo, ngoko umbukeli angatshintsha ulwimi, aziqhele, okanye aphinde asebenzise isimbo sazo kumdlali oxhasayo. Izihloko zesiphelo ezitywiniweyo zikhona — zii-pixels kuphela kwisakhelo — kodwa zihlala zikhona, kwaye akukho nto ibangela ukuba ukhethe xa isiqulatho sixhasa into eyiyo.

Kutheni le nto i-audio track enye kuphela ephila kwi MP4 yam?

Kuba loo nto yonke ifomati ihambisa ngokunyanisekileyo. Iindlela zesandi ezingaphezulu zingabhalwa kwi MP4, kodwa uxhaso lokudlala emva kwesinye esikuqala asihambelani ngokwaneleyo ukuba izixhobo ezininzi zigcine enye kwaye zisuse ezinye. Ukuba umcebo unegqabaza okanye iilwimi ezimbini, khupha ezi zifayili zesandi ezihlukileyo kunokuba uthembele kuzo kwisiqulathi seefayili esifihlayo. I-MP4 ixhasa kuphela ifomati enye ethandwayo yesihloko esingaphantsi (mov_text), kwaye i-multi-track audio ayithembeki ngaphandle kwee-desktop players.

Ingaba ukusebenzisa i MP4 kudinga ilayisenisi yepateni?

Ayikuko kuwe. Ii codecs ezibandakanyiweyo ziquka iindidi zepateni, kwaye ilayisensi ibekwe ngabantu abathutha ii decoders - ifowuni, umkhangeli zincwadi, indlela yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke ihardware kwaye kutheni i royalty- free efana nayo ikhona, kwaye ayitshintshanga nto malunga nokuguqula ifayile oyinayo.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i MP4?

Akukho nanye, kwaye ifanele ukuqonda kutheni: unikezelo luphawu, ngelixa i bytes ngaphakathi zidityaniswe kwifomati ekhethekileyo. Ukuphinda ubize ifayile ivelisa ifayile igama layo lithembisa into imixholo yayo ayinikezeli, kwaye nantoni na evula ifayile okanye ilahlekile ifayile okanye ifunda ngokungachanekanga. Ukuphela kwendlela efutshane kuhlobo olubini oluyinyani ibhokisi efanayo phantsi kwegama elahlukileyo - kwaye nalapho ukuphinda ubhale ngokuchanekileyo kukhuselekile kunegama elahlukileyo.

Ndingaguqula isiqulathi seefayili esipheleleyo se MP4 iifayili ngenye indlela?

Nge akhawunti, ewe - shiya ngaphaya kunye kwaye zifolwa njengemisebenzi enye endaweni yokuphathwa enye ngexesha, ngemimiselo efanayo esetyenziswa kwiqela kunye neziphumo ezibuyiselweyo kunye. Uguqulelo oluzenzekelayo luqhuba ifayile enye ngexesha (izixhobo zokudibanisa zithatha ezimbini); inkqubo ehlawulweyo ivula uqhubekeko lweqela kunye nobukhulu befayile nganye umda, owenza uguqulelo lwefayile yonke yovimba isebenziseke.

Yintoni eyenza i-MP4 yam ifile emva kokuguqula?

Icinywa. Ulayisho phezulu kunye nempumelelo eguqulweyo zombini zihlala kumncedisi kuphela kude kube umsebenzi ufuna ukuba zigcinwe kwaye zisuswa ngokuzenzekelayo; unikezelo luya phezulu kwi HTTPS kumgca ngamnye. Akukho mntu ufunda imixholo, akukho nto iqulathe isiqulathi seefayili, kwaye akukho nto igqityiwe komnye umntu. Ukuba awufuni ukulindela ucoci oluzenzekelayo, ukuvala umsebenzi ususa iifayile ngokuzenzekelayo.

Ithatha ixesha elingakanani ukutshintsha i-MP4?

Iiyure. Iifayile ezincinci zisebenza ngokukhawuleza, kwaye iimeko ezithatha ixesha elibonakalayo zizo ezizenza umsebenzi obonakalayo: ushicilelo olude olufuna ukuphinde kwenziwe ukukhowuda iframe nge frame, uxwebhu olushayiniweyo oluya kukwazisa uphawu, okanye iqela elikhulu kakhulu. apho uguqulelo luphinda lujikeleze okanye luphinde lupakishe i data ekhoyo ihlala ikhawuleza nokuba ifayile incinci kangakanani na, kuba akukho nto iguqulelwe kwikhowudi.

Ndifuna i-akhawunti yokutshintsha i-MP4?

Akukho nanye. Nciphisa ifayile, khetha ifomati yemveliso, kwaye ulayishe impumelelo - akukho ubhaliso, akukho email, akukho phawu lwamanzi kwinto ebuyayo. I akhawunti ikhona kwizinto ezifuna enye: umda omkhulu kwifayile nganye, uguqulelo lwefayile ezininzi ngexesha elinye endaweni yenye ngexesha elinye, nembali yemisebenzi yakho yangoku.
