Kule minyaka isibhozo idluleyo, ndiye ndafudusela le bhokisi yeekhasethi zevidiyo kumagumbi amane ahlukeneyo nakwindlu enye. Iividiyo zosapho kwasebuntwaneni bam.
Emva kweeyure ezingaphezulu kwama-600 zomsebenzi, ekugqibeleni ndiye ndazenza zifakwe ekhompyutheni kwaye zicwangciswe kakuhle ukuze iiteyiphu zilahlwe kude.
Nantsi indlela ekhangeleka ngayo ngoku le vidiyo:
Zonke iividiyo zosapho zenziwe ekhompyutheni kwaye ziyafumaneka ukuze zijongwe kwiseva yemidiya yabucala
Oku kubangele iiklip zevidiyo ezingama-513. Ngamnye unegama, inkcazo, umhla wokurekhoda, iithegi zabo bonke abathathi-nxaxheba ababonisa ubudala ngexesha lokurekhoda. Yonke into ibanjwe kwi-server ye-media yangasese kuphela amalungu osapho anokufikelela kuyo, kwaye ukusingatha iindleko ezingaphantsi kwe-$ 1 ngenyanga.
Eli nqaku likuxelela yonke into endiyenzileyo, kutheni kuthathe iminyaka esibhozo ukufika apho - kunye nendlela yokufumana iziphumo ezifanayo ngokulula nangokukhawuleza.
Umzamo wokuqala ongenangqondo
Malunga nowama-2010, umama wathenga iVHS kwisiguquli seDVD kwaye waqhuba zonke iividiyo zethu zasekhaya ngayo.
IiDVD zoqobo ezibhalwe nguMama (Andazi ukuba kwenzeke ntoni ngoonobumba abangekhoyo)
Ingxaki kukuba umama wenze iDVD enye kuphela. Zonke izalamane zihlala kumazwe ahlukeneyo, ngoko ke kwakungekho lula ukudlulisa iidiski.
Ngo-2012, usisi wam wandinika ezi DVD. Ndikhuphe iifayile zevidiyo kwaye ndalayisha yonke into kwisitoreji samafu. Ingxaki isonjululwe!
DVD rips iividiyo usapho kugcino Google Cloud
Kwiiveki ezimbalwa kamva ndabuza enoba kukho nabani na owakha wawabukela la khasethi. Kwathi kanti akukho mntu ujongileyo. Nam khange ndijonge. Ngexesha le-YouTube, kububudenge ukukhuphela iifayile zeeyure ezintathu zomxholo ongaziwayo ukukhangela imifanekiso enomdla.
Ngumama kuphela owavuyayo: βKulungile,β watsho, βngoku sinokuzilahla zonke ezi khasethi?β
Owu-oh. Lo ngumbuzo owoyikayo. Kuthekani ukuba siye siwaphosile amagama athile? Kuthekani ukuba iiteyiphu zinokufakwa ekhompyutheni kumgangatho ophezulu? Kuthekani ukuba iileyibhile ziqulethe ulwazi olubalulekileyo?
Bendisoloko ndiziva ndingakhululekanga ngokulahla ezoqobo de ndiqiniseke ngokupheleleyo ukuba ividiyo ikhutshelwe ngowona mgangatho uphakamileyo. Ngaloo ndlela, kwafuneka ndiwuthabathele ngokwam lo mbandela.
Ndandingazi ukuba ndizifaka entwenini.
Ayivakali inzima kangako
Ukuba awusiqondi isizathu sokuba ndithathe iminyaka esibhozo kunye namakhulu eeyure, andikusoli. Kwakhona ndandicinga ukuba yonke into yayiza kuba lula.
Nantsi indlela inkqubo yokwenza idijithali ijongeka ngayo ukusuka ekuqaleni ukuya ekugqibeleni:
Ngokuchanekileyo, le yindlela ekhangeleka ngayo kwithiyori. Nantsi indlela eyenzeka ngayo ekusebenzeni:
Ixesha elininzi lalichithwa kusenziwa ngokutsha oko kwakusele kwenziwe. Bendiya kugqiba inqanaba elinye, kwaye emva kwenqanaba elinye okanye ezibini ndiza kufumana isiphene kubuchule. Kwafuneka ndibuyele umva ndiyenze kwakhona. Umzekelo, ndithathe iiteyiphu zevidiyo ezingama-20 ngaphambi kokuba ndiqonde ukuba iaudio yayingaphandle kolungelelwaniso. Okanye, emva kweeveki ezininzi zokuhlela, ndiye ndafumanisa ukuba bendithumela ividiyo ngefomathi engaxhasi ukusasazwa kwe-Intanethi.
Ukugcina ingqondo yomfundi, ndibonisa inkqubo ngokungathi iqhubela phambili ngokucwangcisiweyo, ukuze ndinganyanzeli ukuba utsibe umva kwaye wenze yonke into kwakhona, njengoko bekufuneka ndenze.
Inyathelo 1: Thatha ividiyo
Kulungile, masibuyele ku-2012. UMama wayefuna ngokwenene ukulahla iikhasethi awayezigcine kangangeminyaka engamashumi amabini, ngoko xa sasiqala ukudibana, ngoko nangoko wandinika ikhadibhodi enkulu. Yaqala ke ngolo hlobo imfuno yam yokwenza idijithali.
Isisombululo esicacileyo yayikukuphathisa iingcali umsebenzi. Iinkampani ezininzi zibandakanyeka kwidijithali, kwaye ezinye zisebenza ngokukodwa kwividiyo yasekhaya.
Kodwa ndinobuntu obuyimfihlo, kwaye bendingafuni abantu endingabaziyo babukele ividiyo yosapho lwethu lwamaxesha ethu asondeleleneyo, kubandakanya noqeqesho lwam lwamanzi (kwiminyaka efanelekileyo; akukho nto ingaqhelekanga!). Kwaye ndaye ndacinga ukuba akukho nto inzima malunga nedijithali.
Spoiler: kwabonakala kunzima nyani.
Umzamo wokuqala wokuthatha ividiyo
Utata wayesenayo iVCR yentsapho endala, ngoko ndamcela ukuba ayigrumbe kwigumbi elingaphantsi kwesidlo sangokuhlwa sentsapho esilandelayo. Ndithenge eAmazon kwaye ndasebenza.
, Isixhobo sokuqala se-A/V endisithengileyo ngexesha lokufuna iminyaka emininzi
Ukucwangcisa ividiyo kwisixhobo sokubamba i-USB, ndisebenzise inkqubo yeVirtualDub; inguqulelo ka-2012 iphelelwe lixesha, kodwa ayibalulekanga.
Imifanekiso kwinkqubo yeVirtualDub yam ndifundela utata incwadi ndineminyaka emine
Ukuhlaselwa ngesandi esigqwethekileyo
Xa ndiqala inkqubo yokuhlela, ndiye ndaqaphela ukuphuma kongqamaniso phakathi kweaudio kunye nevidiyo. Kulungile, akukho ngxaki. Ndiyakwazi ukuhambisa isandi kancinci.
Kwimizuzu elishumi emva koko yaphinda yacinywa. Ngaba andizange ndiyishukumise ngokwaneleyo okokuqala?
Kuye kwavela kum ngokuthe ngcembe ukuba iaudio kunye nevidiyo ayiphelelanga nje ekungqinelanisweni, yayirekhodwa ngesantya esahlukileyo. Kuyo yonke iteyiphu ziyahlukana ngakumbi nangakumbi. Ukuvumelanisa, kuye kwafuneka ndilungelelanise isandi ngesandla rhoqo ngemizuzu embalwa.
Ukuba useto lwakho lubamba iaudio kunye nevidiyo ngamaxabiso ahlukeneyo, ke ekuphela kwesisombululo kukulungelelanisa iaudio rhoqo kwimizuzu embalwa.
Ngaba unokuyithelekelela indlela ekunzima ngayo ukwahlula phakathi kwesandi seemillisecond ezili-10 ngaphambili okanye i-milliseconds ezili-10 kamva? Kunzima ngenene! Zigwebe ngokwakho.
Kule vidiyo ndidlala nentshontsho lam lekati elihluphekayo, eligama linguBlack Magic. Isandi singaphandle kancinci. Qinisekisa ukuba uphambi komfanekiso okanye usemva kwemifanekiso?
Umzekelo wekliphu yevidiyo enesandi esingaphandle kwe-sync kunye nomfanekiso
Ngeli xesha ukutsiba kweBlack Magic, isiqwenga sehlise isantya kahlanu:
Akukho ngqamaniso phakathi kwesandi kunye nomfanekiso, ukucotha kahlanu
Phendula: Isandi siza kunye nokulibaziseka kweemillisecond ezimbalwa.
Mhlawumbi uchithe ikhulu elongezelelweyo leedola endaweni yamakhulu eeyure zexesha lakho?
Ulungiso oluvakalayo lulodwa lwalufuna iiyure ezininzi zomsebenzi odinisayo, nophambanayo. Ekugqibeleni kuye kwafika kum ukuba ndingakuphepha ukuvumelanisa ngokusebenzisa isixhobo esingcono, esibiza kakhulu sokuthatha ividiyo. Emva kophando oluthile ndithenge entsha kwiAmazon:
Umzamo wam wesibini wokuthenga
Nokuba ngesixhobo esitsha, ukungabikho kongqamaniso akukhange kunyamalale.
I-VCR enesiqalo "esiphezulu".
Mhlawumbi ingxaki ikwiVCR. Vula bathi akuyi kubakho ngaphandle kokuvumelanisa kwi-VCR kunye "ne-corrector esekelwe kwixesha" (TBC), lo msebenzi ufumaneka kuzo zonke i-Super VHS (S-VHS) VCRs.
Ewe, kunjalo! Bekutheni ze ndizixakekise ngobubhanxa? eqhelekileyo VCR, xa ikhona ΡΡΠΏΠ΅Ρ-VCR esombulula ingxaki?
Akukho mntu wenza i-S-VHS VCRs kwakhona, kodwa zisafumaneka kwi-eBay. Nge-179 yeedola ndithenge i-JVC SR-V10U, ebonakala isebenza kakuhle kwi-VHS digitization:
IVintage JVC SR-V10U VCR endiyithenge kwi-eBay nge-179 yeedola
Isishicileli sevidiyo βesiphezuluβ safika ngeposi. Emva kweenyanga ezininzi zokuzabalaza nge-audio ngaphandle kokuvumelanisa, ndandivuya kakhulu kuba kukho izixhobo eziza kusombulula zonke iingxaki zam.
Ndavula ibhokisi, ndadibanisa yonke into, kodwa isandi sasirekhodwa ngesantya esahlukileyo. Eh.
Ukukhangela okudinwayo, ukulungisa iingxaki kunye neminyaka emininzi yomzabalazo
Ndaqalisa iinzame zam ezibuthathaka zokusombulula ingxaki. Kwakubuhlungu ukubukela. Ngalo lonke ixesha ndikhupha zonke izixhobo kwi-closet, ndakhasa ngamadolo emva kwedesktop ukuze ndidibanise yonke into, ndizama ukufota ividiyo-kwaye ndaphinda ndabukela ukuba akukho nto isebenzayo.
Ngoko ndadibana nesithuba seforum engahleliwe ukusuka kwi-2008, ethetha ngokufaka umqhubi othile waseTshayina ongaqhelekanga ngaphandle kokutyikitya ... Lo ngumbono ombi, kodwa ndinqwenela. Noko ke, akazange ancede.
Ndizame iinkqubo ezahlukeneyo zedijithali. Ithengiwe ukucoca iintloko zemagnethi zeVCR. Ithengiwe . Akukho nto yandincedayo.
Ndancama ndancama, ndacima yonke into ndaza ndafihla izixhobo kwigunjana kangangeenyanga ezimbalwa.
Sinikezela kwaye sinika iingcali iikhasethi
Ngu-2018. Ndandifuduse iikhasethi zeVHS neetoni zezixhobo kumagumbi amane ahlukeneyo yaye ndandisele ndiza kufuduka eNew York ndiye eMassachusetts. Andizange ndiwafumane amandla okuphinda ndiwathwale kuba ndandisele ndiqonda ukuba andisoze ndiwugqibe ngokwam lo msebenzi.
Ndabuza usapho ukuba ngaba kunokwenzeka ukuthatha iiteyipu kwinkampani yedijithali. Ngethamsanqa, akukho namnye owachasayo - wonke umntu wayefuna ukuphinda abone okurekhodiweyo.
Π―: Kodwa oko kuthetha ukuba inkampani ethile iya kuba nokufikelela kuzo zonke iividiyo zethu zasekhaya. Ngaba iyakufanela?
Dade: Andimhoyanga. Nguwe wedwa onexhala le nto. Yima, ngoko ubunokuhlawula umntu kwasekuqaleni?
Π―: Uh-uh...
Ukufakwa kwedijithali kuzo zonke iiteyiphu ezingama-45 kubiza i-750 yeedola. Kubonakala ngathi kuyabiza, kodwa ngelo xesha ngendihlawule nantoni na ukuba ndingaphinde ndijongane nesi sixhobo.
Xa behambisa iifayile, umgangatho wevidiyo wawungcono ngokuqinisekileyo. Kwizakhelo zam, ukugqwetheka kwakusoloko kubonakala emaphethelweni esakhelo, kodwa iingcali zenza yonke into kwidijithali ngaphandle kokuphazamiseka konke konke. Eyona nto ibalulekileyo kukuba iaudio kunye nevidiyo zilungelelaniswe ngokugqibeleleyo.
Nantsi ividiyo ethelekisa ukwenziwa kwedijithali kunye neenzame zam zokukhulisa ikhaya:
Uthelekiso lobuchwephesha kunye nokwenziwa kwedijithali kwividiyo apho umama wam enza ifilimu ilinge lam lokuqala lokucwangcisa
Inyathelo 2: Hlela
Xa ufota ekhaya, malunga ne-90% yezinto eziphathekayo, i-8% inomdla, kwaye i-2% iyamangalisa. Emva kokwenziwa kwedijithali, usenomsebenzi omninzi ekufuneka wenziwe.
Ukuhlela kwiAdobe Premiere
Kwiteyiphu yeVHS, umjelo omde weekliphu zevidiyo udityaniswe ngamacandelo angenanto. Ukuhlela iteyiphu, kufuneka umisele ukuba ikliphu nganye iqala kwaye iphelela phi.
Ukuhlela, ndasebenzisa i-Adobe Premiere Elements, ebiza ngaphantsi kwe-$ 100 yelayisensi yobomi. Olona phawu lwayo lubaluleke kakhulu luluhlu lwexesha elinokwehla. Ikuvumela ukuba ufumane ngokukhawuleza imida yomboniso kwaye emva koko usondeze ukuze ufumane eyona isakhelo sevidiyo apho ikliphu iqala okanye iphela khona.
Ixesha eliBalulekileyo ngoSondezo kwi-Adobe Premiere Elements
Ingxaki nge-Premiere kukuba inkqubo ifuna umzamo oqhubekayo wezandla, kodwa i-digitization kunye nokuthumela ngaphandle kuthatha ixesha elide. Nalu ulandelelwano lwam lwemisebenzi:
- Vula ifayile ekrwada equlathe 30-120 imizuzu yevidiyo.
- Phawula imida yekliphu nganye.
- Thumela ikliphu.
- Linda imizuzu emi-2 ukuya kweli-15 ukuze ukuthunyelwa ngaphandle kugqitywe.
- Phinda amanyathelo 2-4 de uphelelwe tape.
Ukulinda ixesha elide kwakuthetha ukuba ndandisoloko nditshintsha phakathi kokuhlelwa kwevidiyo kunye nomnye umsebenzi, ndisusa ingqalelo yam emva nangaphambili iiyure ezininzi.
Enye intsilelo yayikungaphinda-phinde kuveliswe. Ukulungisa impazamo encinci kwakuphantse kube nzima njengokwenza yonke into ukusuka ekuqaleni. Oku kwandibetha kakhulu xa kuziwa ekuthumeleni iividiyo. Kulapho ndiye ndafumanisa ukuba ukuze usasazeke kwi-Intanethi, bekufuneka ukuba uqale uthumele ividiyo kwifomati exhaswa ngabakhangeli bewebhu. Bendijongene nokukhetha: ndiqale ngokutsha inkqubo edinayo yokuthumela ngaphandle amakhulukhulu eekliphu, okanye ndiphinde ndifake iikhowudi kwiividiyo ezithunyelwe kwenye indawo enomgangatho othotyiweyo.
Ukuhlela okuzenzekelayo
Emva kokuchitha ixesha elininzi ndisenza umsebenzi wezandla, ndiye ndazibuza ukuba i-AI ingasetyenziswa na apha ngandlela thile. Ukubona imida yekliphu kubonakala kungumsebenzi ofanelekileyo wokufunda ngomatshini. Ndandisazi ukuba ukuchaneka akuyi kuphelela, kodwa makenze ubuncinane i-80% yomsebenzi kwaye ndiya kulungisa i-20 yokugqibela.
Ndiye ndazama isixhobo esibizwa , ehlalutya iifayile zevidiyo kwaye ibonelele ngezitampu zamaxesha apho utshintsho lwendawo lwenzeka khona:

...Isixhobo siye sabonisa ukuchaneka okumalunga nama-80%, kodwa ukusivavanya ukuba sisebenze kuthathe ixesha elingaphezulu kunokuba besiligcinile. Nangona kunjalo, i-pyscenedetect yenza enye yezona zinto zibalulekileyo ezifunyenweyo kuyo yonke iprojekthi: ukufumanisa imida yendawo kunye neziqeshana zokuthumela ngaphandle yimisebenzi eyahlukileyo.
Ndakhumbula ukuba ndingumprogramu
Ukuza kuthi ga ngoku, ndithathe yonke into endiyenzileyo kwi-Adobe Premiere βnjengokuhlela.β Ukusika iziqeshana ezisuka kwimifanekiso ekrwada kwakubonakala kuqhagamshelwe ngokungenakuthelekiswa nanto ekufumaneni imida yekliphu, kuba yindlela iPremiere ewubonise ngayo umsebenzi. Xa i-pyscenedetect iprinte itafile yemethadatha, indenze ndaqonda ukuba ndinokwahlula ukukhangela indawo kwividiyo ethunyelwa ngaphandle. Yaba yinkqubela phambili.
Isizathu sokuhlela bekuyindinisa kwaye kuthatha ixesha kungenxa yokuba kuye kwafuneka ndilinde iPremiere ukuthumela ngaphandle kwekliphu nganye. Ukuba bendirekhode imetadata kwi-spreadsheet kwaye ndibhale iskripthi esithumela ngaphandle ividiyo ngokuzenzekelayo, inkqubo yokuhlela ngeyidlule.
Ngaphezu koko, i-spreadsheets zandise kakhulu umda we-metadata. Ekuqaleni, ndifake imetadata kwigama lefayile, kodwa oku kuyayinqanda. Ukuba ne-spreadsheet siphelele kundivumele ukuba ndibeke ikhathalogu yolwazi oluninzi malunga nekliphu, njengokuthi ngubani okuyo, xa yayirekhodwa, kunye nayo nayiphi na enye idatha endifuna ukuyibonisa ngexesha levidiyo.
Ispredishithi esikhulu esinemethadatha malunga neevidiyo zam zasekhaya
Ndiye ndakwazi kamva ukusebenzisa le metadata ukongeza ulwazi kwiziqeshana, ezinje ngokuba sibadala kangakanani sonke kunye nenkcazo eneenkcukacha yokwenzekayo kwikliphu.
Ukusebenza kwespreadsheet kukuvumela ukuba urekhode imetadata, ekunika ulwazi oluninzi malunga neziqeshana zakho kwaye zizenze zibe lula ukuzijonga.
Impumelelo yesisombululo esizenzekelayo
Ukuba ne-spreadsheets, ndabhala , esike ividiyo ekrwada ibe yikliphu esekwe kwidatha ye-CSV.
Naku ushicilelo lwendlela ekhangeleka ngayo xa isenziwa:
Ngeli xesha ndichithe amakhulu iiyure, ukhetha ngokudinayo imida yekliphu kwiPremiere, ucinezela ukuthumela ngaphandle, ulinde imizuzu embalwa ukuba igqibe, kwaye emva koko uqale kwakhona. Ayisiyiyo loo nto kuphela, kodwa inkqubo yaphindwa kaninzi kwiziqeshana ezifanayo xa iingxaki zomgangatho zafunyanwa kamva.
Emva kokuba ndizenzele iziqendwana, kwasuswa umthwalo omkhulu emagxeni am. Ndandingasenaxhala lokulibala imetadata okanye ukukhetha ifomati yemveliso engalunganga. Ukuba impazamo yenzeka kamva, ungalungisa ngokulula iskripthi kwaye uphinde yonke into.
Ukwenza idijithali kunye nokuhlela izixhobo zevidiyo sisiqingatha kuphela sedabi. Kusafuneka sifumane inketho efanelekileyo yokupapasha kwi-Intanethi ukuze zonke izalamane zibukele ividiyo yosapho ngendlela efanelekileyo ngokusasaza njengakwiYouTube.
Kwinxalenye yesibini yenqaku, ndiya kukuxelela ngokweenkcukacha indlela yokuseta iseva yemithombo yeendaba evulekileyo kunye nazo zonke iikliphu zevidiyo, ezindibiza kuphela i-77 cents ngenyanga.
Ukuqhubekeka,
