MOV Ukushintsha

Yini ihele MOV?

I-MOV iyifomethi yesitsha se-multimedia esakhiwe yi-Apple ye-QuickTime.

Ingabe ihele MOV lifana ne MP4 ngaphansi?

Isakhiwo sabo sifana kakhulu. MOV ikhiwa kusuka ku-ISO Base Media File Format box layout isebenzisa i-MP4 — umhlahlandlela we-atoms ogcina idatha yemidiya kanye ne-index echaza lapho ifreyimu ngayinye iqala khona. Lokhu kusho ukuthi ukushintsha phakathi kwabo kuvame ukuba yi-rewrap ngaphezu kokuphinda-code: ama-streams akopiwe ngaphandle kokuchofoza futhi i-wrapper kuphela ibhalwe kabusha, okuthatha amasekondi ngisho kwifayela le-feature-length. MOV Apple's QuickTime isitsha, ethunyelwe ngo-1991 futhi akazange ashintshe ifomu iPhone, iPad noma Final Cut Pro timeline ubhala ngokuzenzakalela.

Kungani amathuluzi amasha abuyela emuva MOV?

Ngenxa yokuthi ifakwe ukwenziwa umsebenzi kuyo kunesihlukaniso. Ifomethi igcina ubuhle nesakhiwo ngokuvula okuphindiwe, ukuhlela nokulondoloza kabusha, okuwukuthi okudingayo ukukhishwa kwepayipi kanye nohlobo lokudlulisa olucacile lokuhweba. Imiphumela iyizici: gcina MOV njenge master futhi uguqule ikhophi kunoma ubani odinga ukubheka. MOV yifomethi abashicileli abaqeqeshiwe bacela, ngoba ihlala iphinda i-round-trips nge Final Cut Pro, Premiere ne DaVinci Resolve ngaphandle kokulahlekelwa kohlobo.

Kungani isiphequluli sami singadlala ihele MOV?

Amabhuleki athumela ama-decoders kuluhlu oluncane lwefomethi, futhi MOV ayikho kulo — ilayisense, i-codec ehlukene evumela, noma nje ubudala bayo bugcina bungaphandle. Ihele alilahlekile futhi umdlali wedesktop uzovula, kodwa akukho okwenziwayo kukhasi kuzokwenza ibhuleki liyibonise. Ukushintsha ukuguqula kube nendawo yokugcinwa ye-web-native kuyindlela ethembekile kuphela yokudlala ngaphakathi. Amafayela MOV akhulu, futhi ngaphandle kwe-Apple ecosystem ukusakazwa kosizo kuncane kuna-MP4 - ama-Android adala futhi amanye ama-Smart TVs azowayeka.

Ingabe MOV izodlala kufoni noma TV ngaphandle kokushaya ibhayisikili?

Ngokuvamile, yebo, ngoba ama-chips efonini, ama-tablets nama-televisions afaka ikhophi le-payload e-silicon ekhethekile, hhayi kwi-processor eyinhloko. Lokhu kuyinto ehlukile phakathi kwevidiyo edlala i-cool ngehora elilodwa nelinye elifaka i-heat device futhi liyihlanze imizuzu emashumi amane. lapho ifomu lihla khona, i-app ixhasa i-app, hhayi uku-decode — i-codec iyilungile, i-wrapper yilokho i-gallery app ingakanani. I-MOV ivame ukuthwala i-H.264 noma i-HEVC yokudlulisa, noma i-ProRes uma iyi-editor master, kanye ne-AAC noma umsindo we-PCM ongacindezelwa.

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

Kukhethwa, uma kufakwe kahle. MOV 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 akuyona isizathu sokukhetha uma isiqulatho sixhasa into engokoqobo.

Ingabe kubaluleke ukuthi MOV ingaphezu kweminyaka engu-30?

Ubudala bukhona akuyona inkinga - amafomethi amaningi onyaka akhona alungile, ngokucacile ngoba konke kudlule iminyaka eminingi ukuwafaka. Okubalulekile ukuthi unyaka uthathe isinqumo: amafayela amancane, amaprosesa aphansi, akukho nethiwekhi, futhi amakhono angeke afune umuntu. lapho amanani ahlala khona, ifomu lilungile. lapho ayikho, lena yisizathu sokushintsha.

Ingabe ihele MOV ligcina ama-tracks omsindo amaningi?

Yebo - imixholo yesiNgisi, i-dub ne-comment ingahlala yonke kwifayela elilodwa ne-player eshintsha phakathi kwazo. Izinqumo ezimbili: amafoni amaningi nama-television adlalayo abonisa kuphela umculo wokuqala kodwa amanye akhona, futhi ukuguqulwa kufomethi ngaphandle kosizo olukhulu lwe-tracks agcina umculo owodwa futhi akhuphula okunye. Khetha umculo ofuna ukuwuguqula, hhayi ukucabanga ukuthi iyiphi ehlala.

Ingabe ngidinga iMac ukusebenza namafayela MOV?

Akuna. Ifomethi yavela Apple futhi yilokho izinhlelo zayo nesoftware kukhiqiza ngokuzenzakalela, kodwa amafayela ngokwawo zivamile futhi ukufunda kahle kwezinye izindawo ngethuluzi elifanele. Ukushintsha lapha kwenzeka kuseva, ngakho akukho QuickTime ukufakela, akukho Apple hardware futhi akukho platform-specific codec pack ihlobene nanoma kuphi kwinqubo.

Ingabe MOV igcina izibonisi zesigaba?

Ikwenza — amasigaba ahlala kwi-metadata yebhokisi, ngakho ukurekhodwa okude kungafinyelelwa ngengxenye endaweni yokudonsa ibha yokuqhubekela phambili. Baphila ngokucindezela kabusha kufomethi ehlukile yesigaba esizizwayo futhi bakhuphuka, ngokuzizwayo, ngenye engakholeki. Uma amasigaba abalulekile, lokhu kufanelekile ukubheka ngaphambi kokukhetha ifomethi yesingeniso endaweni yokuqhubeka.

Ingabe ukusebenzisa MOV kuthatha ilayisense lepatenti?

Akunakho okukudingayo. Ama-codecs ahlobene ahlobene ne-patent pools, futhi ilayisense ibekwe 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 MOV?

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 ubhale kahle kuphephile kunalokho ukushintsha igama.
