Mumakore masere apfuura, ndakatamisa iri bhokisi rematepi evhidhiyo kudzimba ina dzakasiyana neimba imwe. Mavhidhiyo emhuri kubva paudiki hwangu.
Pashure pemaawa anopfuura 600 ebasa, pakupedzisira ndakaaisa pakombiyuta ndokuaronga zvakanaka kuitira kuti makaseti araswe.
Hezvino izvo mavhidhiyo anotaridzika zvino:
Mavhidhiyo ese emhuri akaiswa mudigito uye anowanikwa kuti atariswe kubva kune yakavanzika midhiya server
Izvi zvakakonzera 513 mavhidhiyo ega ega. Imwe neimwe ine zita, tsananguro, zuva rekurekodha, ma tag kune vese vatori vechikamu, zvichiratidza zera panguva yekurekodha. Zvese zviri pane yakavanzika midhiya server iyo chete nhengo dzemhuri inokwanisa kuwana, uye yekutambira inodhura isingasviki $1 pamwedzi.
Ichi chinyorwa chinotaura nezve zvese zvandakaita, nei zvakatora makore masere, uye maitiro ekuwana mhedzisiro iri nyore uye nekukurumidza.
Kuedza kwekutanga kusina maturo
Muna 2010, amai vangu vakatenga imwe mhando yeVHS kuDVD converter uye vakamhanyisa mavhidhiyo edu ese epamba kuburikidza nayo.
MaDVD ekutanga akarekodhwa naamai vangu (handizive zvakaitika kune mavara asipo)
Dambudziko nderekuti, Amai vakangoita seti imwe chete yemaDVD. Vese vehukama vanogara mumatunhu akasiyana, saka zvaive zvisingaite kupfuudza madhisiki.
Muna 2012, sisi vangu vakandipa maDVD aya. Ndakakopa mafaera evhidhiyo uye ndakaisa zvese kuchengetedzo yegore. Dambudziko ragadziriswa!
MaDVD anobvarura mavhidhiyo emhuri muGoogle Cloud kuchengetedza
Mavhiki mashoma gare gare ndakabvunza kana mumwe munhu akanga aona matepi. Zvakaratidza kuti hapana aizviona. Handina kana kutarisa. Munguva yeYouTube, kudhawunirodha mafaera emaawa matatu ezvisingazivikanwe zvirimo mukutsvaga inonakidza tsoka hupenzi.
Amai vangu bedzi ndivo vakafadzwa: βZvakanaka,β vakadaro, βzvino tingarasa here aya makaseti ose pakupedzisira?β
Oo-o. Uyu mubvunzo wakaipa. Zvakadini kana takapotsa mamwe manyoro? Ko kana matepi achikwanisa kuiswa padigital pamhando yepamusoro? Ko kana mavara acho aine ruzivo rwakakosha?
Ndagara ndichinzwa kusasununguka kurasa zvepakutanga kudzamara pave nechokwadi chakakwana chekuti vhidhiyo yacho yakakopwa kumhando yepamusoro inogoneka. Saka, ndaifanira kudzika kubhizinesi.
Ndakatoshaya kuti ndaipindwa nei.
Hazvina kunzwika zvakanyanya
Kana musinganzwisise kuti sei zvakanditorera makore masere nemazana emaawa, handikupei mhosva. Ndaifungawo kuti zvaizova nyore.
Hezvino izvo digitization maitiro anotaridzika kubva pakutanga kusvika pakupedzisira:
Kunyanya chaizvo, aya ndiwo maitiro azvinotaridzika mudzidziso. Heino maitiro azvakaita mukuita:
Nguva zhinji yaipedzwa kugadzirisa zvakanga zvatoitwa. Ndakapedza nhanho imwe, uye mushure mechikamu chimwe kana maviri ndakawana imwe mhando yekukanganisa muhunyanzvi. Ndaifanira kudzokera ndoitazve. Semuyenzaniso, ndakapfura vhidhiyo kubva pamatepi makumi maviri ndisati ndaona kuti odhiyo yacho yaive isiri kuenderana. Kana kuti mushure memavhiki ekugadzirisa, ndakazviona ndatumira vhidhiyo mune fomati isingatsigire kutenderera pawebhu.
Kuchengetedza hutsanana hwemuverengi, ndiri kuisa maitiro sekunge ari kufambira mberi nenzira yakarongeka kuti usarambe uchisvetuka kumashure nekuitazve zvese, sezvandaifanira kuita.
Danho 1 Bata vhidhiyo
Zvakanaka, kudzokera ku2012. Amai vaida chaizvo kurasa makaseti avakanga vachengeta kwemakore makumi maviri, saka patakatanga kuonana, vakabva vangonditambidza kadhibhokisi hombe. Ndokutanga kuda kwangu kuita digitalize.
Sarudzo iri pachena yaive yekupa basa kune nyanzvi. Makambani mazhinji ari kuita digitization, uye mamwe anonyanya hunyanzvi muvhidhiyo yemumba.
Asi ndine hanya nezvekuvanzika uye ndaisada kuti vasingazivi vaone vhidhiyo yemhuri yedu nenguva dzepedyo dzehupenyu hwangu, kusanganisira kudzidziswa kwangu kwepoto (pazera rakakodzera; hapana chinoshamisa!). Uye ini zvakare ndakafunga kuti hapana chakaoma mukuita digitization.
Spoiler: zvaita kunge zvakaoma.
Kuedza kwekutanga kutora vhidhiyo
Baba vangu vakanga vachine VCR yekare yemhuri, naizvozvo ndakavakumbira kuichera kunze kwekamuri repasi nokuda kwechisvusvuro chemhuri chaitevera. Ndakatenga paAmazon ndokudzika kubhizinesi.
, yekutanga yezvishandiso zvakawanda zveA/V zvandakatenga panguva yekuda kwemakore akawanda
Kuti ndigadzirise vhidhiyo kubva ku USB yekutora mudziyo, ndakashandisa chirongwa cheVirtualDub, iyo 2012 vhezheni ishoma, asi haina kutsoropodza.
Mafuremu muchirongwa cheVirtualDub, pandakaverenga bhuku kuna baba vangu pazera ramakore mana
Kurwisa nekukanganiswa kwenzwi
Pandakatanga maitiro ekugadzirisa, ndakaona zvishoma kunze kwekuenderana pakati pekuteerera nevhidhiyo. Zvakanaka, hapana dambudziko. Ndinogona kufambisa inzwi zvishoma.
Maminitsi gumi gare gare, akange asisawirirani zvakare. Handina here kuifambisa zvishoma kekutanga?
Zvakazobuda pandiri zvishoma nezvishoma kuti odhiyo nevhidhiyo hazvisi zvekungoenderana, zvinorekodhwa nekumhanya kwakasiyana. Mutepi yese, ivo vanosiyana zvakanyanya uye zvakanyanya. Kuti ndiwirirane, ndaifanira kugadzirisa ruzha pamaminetsi mashoma ega ega.
Kana setup yako ichitora odhiyo nevhidhiyo pamitengo yakasiyana, saka mhinduro chete ndeyekugadzirisa manzwi maminetsi ega ega.
Unogona here kufungidzira kuti zvakaoma sei kusiyanisa inzwi 10 milliseconds kare kana gumi milliseconds gare gare? Zvakaoma hazvo! Zvitongere wega.
Muvhidhiyo iyi, ndiri kutamba nekatsi yangu inotambura, ine murwere, ane zita rinonzi Black Magic. Inzwi racho harina kuwiriraniswa zvishoma. Ona kuti iri kumberi kwemufananidzo here kana kuti kwadoka?
Muenzaniso wevhidhiyo klipu ine ruzha uye mufananidzo usingawirirane
Panguva ino, Black Magic inosvetuka, chidimbu chine kudzika-kashanu kuderera:
Ruzha uye mufananidzo kunze kwekuenderana, zvishoma zvishoma kashanu
Reply: Inzwi rinouya nekunonoka kwemamilliseconds mashoma.
Zvichida shandisa imwe zana remadhora panzvimbo yemazana emaawa enguva yako pachako?
Kururamisa kwoga kwoga kwaida maawa akawanda ebasa rinonetesa, rinopengesa. Pakupedzisira zvakazoitika kwandiri kuti desync inogona kudzivirirwa nekushandisa iri nani uye inodhura zvakanyanya vhidhiyo yekutora mudziyo. Mushure mekutsvagisa, ndakatenga imwe paAmazon:
Kuedza kwangu kwechipiri kutenga
Kunyangwe nemudziyo mutsva, desync haina kunyangarika chero kupi.
VCR ine prefix "super"
Pamwe dambudziko riri paVCR. On zvakataurwa kuti hapazove ne desynchronization paVCR ine "time-based corrector" (TBC), chimiro ichi chinowanikwa pane zvose Super VHS (S-VHS) VCRs.
Zvakanaka, zvirokwazvo! Ko ndaimhanyirei nebenzi zvakajairika VCR kana iripo ΡΡΠΏΠ΅Ρ-VCR inogadzirisa dambudziko?
Hapana anoita S-VHS VCRs zvakare, asi achiri kuwanikwa pa eBay. Nemadhora zana nemakumi manomwe nepfumbamwe, ndakatenga modhi yeJVC SR-V179U, inoita seyakanyatsokodzera VHS digitization:
Vintage JVC SR-V10U VCR Ndakatenga pa eBay nemadhora zana nemakumi manomwe nepfumbamwe
"Super" VCR yakauya mutsamba. Mushure memwedzi yakati wandei ndichinetsekana neaudio kunze kwekuenderana, ndakafara kuti pakanga paine michina yaizogadzirisa matambudziko angu ese.
Ndakavhura bhokisi, ndakabatanidza zvese - asi ruzha rwakanga rwuchiri kurekodhwa nekumhanya kwakasiyana. Eh.
Kutsvaga kunonetesa, kugadzirisa matambudziko uye makore ekutambura
Ndakatanga kuyedza kugadzirisa dambudziko. Zvairwadza kutarisa. Pese pandaidhonza midziyo yese kubva muwadhiropu, ndichikambaira nemabvi angu kuseri kwedesktop kuti ndibatanidze zvese, kuyedza kutora vhidhiyo - uye zvakare ndakatarisa kuti hapana chakashanda.
Ndakasangana nechimbichimbi forum post kubva muna 2008 pamusoro pekuisa mumwe mutyairi wechiChinese asina kusaina⦠Ipfungwa inotyisa, asi ndapererwa. Zvisinei, haana kubatsira.
Ndakaedza zvirongwa zvakasiyana zvedigitizing. Yakatengwa kuchenesa misoro yemagineti yeVCR. Yakatengwa . Hapana chakabatsira.
Nguva dzose ndaikanda mapfumo pasi, ndikasunungura zvinhu zvose, uye ndakaviga midziyo yacho muwadhiropu kweimwe mwedzi mishomanana.
Renda uye upe makaseti kune nyanzvi
Gore ra2018 rasvika. Ndakatamisa matepi evhidhiyo nematani emidziyo kumativi mana edzimba uye ndakanga ndava kuda kutama kubva kuNew York kuenda kuMassachusetts. Ndakashaya simba rekuvatora zvakare, nekuti ndakatoona kuti basa iri handaizopedza ndiri ndega.
Ndakabvunza mhuri yacho kana vaigona kupa makaseti kufemu yedigitization. Sezvineiwo, hapana aipikisa - munhu wese aida kuona marekodhi zvakare.
Π―: Asi zvinoreva kuti imwe kambani ichawana mavhidhiyo edu ese epamba. Zvinokufanira here?
Hanzvadzi: Hongu, ndine hanya. Iwe wega uri kunetseka. Mirira, saka ungadai wangobhadhara mumwe munhu pakutanga?
Π―: Uh-uhβ¦
Digitization yemakaseti ese makumi mana nemashanu inodhura $45. Zvinoita sekunge zvinodhura, asi panguva iyoyo ndingadai ndabhadhara chero chinhu kuti ndisaite nemidziyo iyi zvakare.
Pavakapa mafaera, mhando yevhidhiyo yaive nani. Pamafuremu angu, kumonyaniswa kwaigara kuchionekwa kumacheto kwefuremu, asi nyanzvi dzakaisa zvese pasina kukanganisa zvachose. Kunyanya kukosha, iyo odhiyo nevhidhiyo zvakanyatsoenderana.
Heino vhidhiyo inofananidza digitizing nyanzvi uye kuyedza kwangu kumba:
Kuenzanisa kwehunyanzvi uye hwekuita digitization muvhidhiyo umo amai vangu mafirimu kuedza kwangu kwekutanga kuronga
Danho 2. Kugadzirisa
Mumapfuti epamba, inenge 90% yezvinhu zvinofinha, 8% inofadza, uye 2% inoshamisa. Mushure mekuita digitizing, uchine basa rakawanda rekuita.
Kugadzirisa muAdobe Premiere
Pakaseti yeVHS, rwizi rurefu rwemavhidhiyo akapindirwa nezvikamu zvisina chinhu. Kugadzirisa tepi, unofanirwa kuona kuti clip yega yega inotangira uye inogumira kupi.
Kugadzirisa, ndakashandisa Adobe Premiere Elements, iyo inodhura isingasviki $100 yerezinesi rehupenyu hwese. Chinhu chayo chinonyanya kukosha ndeye scalable timeline. Iyo inoita kuti iwe nekukurumidza uwane mipendero yechiitiko uye wozoswedera mukati kuti uwane iyo chaiyo vhidhiyo furemu panotangira clip kana kupera.
Yakakosha zoom yenguva muAdobe Premiere Elements
Dambudziko nePremiere nderekuti maitirwo acho anoda nguva dzose nhanho dzemanyorero, asi zvinotorawo nguva yakareba kugadzira uye kutumira kunze kwenyika. Heino kutevedzana kwangu kwemaitiro:
- Vhura faira mbishi rine 30-120 maminetsi evhidhiyo.
- Maka miganhu yechikamu chega chega.
- Export clip.
- Mirira 2-15 maminetsi kuti kutumira kunze kupedze.
- Dzokorora matanho 2-4 kusvikira tepi yapera.
Kumirira kwenguva refu kwaireva kuti ndaigara ndichichinja nekudzoka pakati pekugadzirisa vhidhiyo uye rimwe basa, kushandura pfungwa dzangu kumashure nekudzoka kwemaawa.
Kumwe kutadza kwaive kusaberekana. Kugadzirisa kakanganiso kadiki kwakange kwakaoma sekutanga kubva pakutanga. Zvakandirovesa nehana kana zvasvika pakuisa vhidhiyo. Ipapo ndipo pandakaona kuti kuitira kuti ufambe paInternet, zvaive zvakafanira kutanga kutumira iyo vhidhiyo kune fomati inotsigirwa newebhu browser. Ndanga ndatarisana nesarudzo: tangazve maitiro anonetesa ekutumira kunze mazana ezvimedu, kana kuti-encode zvakare mavhidhiyo atumirwa kune imwe fomati ine yakaderedzwa mhando.
Kugadzirisa otomatiki
Mushure menguva yakawanda yakashandiswa pabasa remaoko, ndakashamisika kana AI yaigona kushandiswa pano neimwe nzira. Kusarudza miganhu yezvimedu zvinoita kunge ibasa rakakodzera rekudzidza muchina. Ndaiziva kuti kurongeka kwaisazove kwakakwana, asi ngaaite kanenge 80% yebasa uye ini ndichagadzirisa yekupedzisira 20%.
Ndakaedza mudziyo unonzi , iyo inodhinda mafaera evhidhiyo uye inoburitsa timestamps apo shanduko yechiitiko inoitika:

...Chishandiso chacho chakaratidza huchokwadi hunosvika 80%, asi kutarisa basa racho kwakatora nguva yakawanda kupfuura yayakachengeta. Nekudaro, pyscenedetect yakaita chimwe chezvakakosha zvakawanikwa zvepurojekiti yese: kutsanangura miganhu yezviitiko uye kutumira kunze kwenyika mabasa akasiyana.
Ndakarangarira kuti ndiri programmer
Kusvika panguva ino, ndaifunga zvese zvandakaita muAdobe Premiere se "kugadzirisa". Kucheka zvimedu kubva kumafuremu akaomeswa zvaiita sezviri kufambidzana nekutsvaga miganhu yeklip, nekuti ndiwo maonerwo akaitwa basa nePremiere. Apo pyscenedetect yakadhinda tafura yemetadata, yakaita kuti ndione kuti ndaigona kuparadzanisa kutsvaga kwechiitiko kubva kuvhidhiyo kunze. Yakanga iri budiriro.
Chikonzero kugadzirisa kwainetesa uye kuchitora nguva nekuti ndaifanira kumirira apo Premiere yaiburitsa imwe clip. Dai ndaizonyora metadata muspredishiti ndonyora script inotumira vhidhiyo kunze, maitiro ekugadzirisa aizopfuura.
Uyezve, maspredishiti akawedzera zvakanyanya kuwanda kwemetadata. Pakutanga, ini ndinorovera metadata muzita refaira, asi izvi zvinovamisa. Kuve nespredishiti rese kwakanditendera kuti nditore ruzivo rwakawanda nezve clip, sekuti ndiani aivemo, payakarekodhwa, uye chero imwe data yandinoda kuratidza kana vhidhiyo yaratidzwa.
Giant spreadsheet ine metadata nezvemavhidhiyo angu ekumba
Gare gare, ndakakwanisa kushandisa iyi metadata kuwedzera ruzivo kune zvimedu, senge taive nemakore mangani tese uye tsananguro yakadzama yezviri kuitika mu clip.
Kushanda kweSpreadsheet kunokutendera kurekodha metadata inopa rumwe ruzivo nezve zvimedu uye zvinoita kuti zvive nyore kuona
Kubudirira kweiyo automated solution
Ndiine maspredishiti, ndakanyora , iyo yakacheka vhidhiyo mbishi kuita zvimedu zvinoenderana neCSV data.
Hezvino zvinoita sekunge mukuita:
Parizvino ndapedza mazana maawa, kusarudza zvine mutsindo miganho yeklipu muPremiere, kurova kunze, kumirira maminetsi mashoma kuti ipedze, uyezve kutangazve. Kwete izvozvo chete, maitiro akadzokororwa kakawanda pazvikamu zvakafanana apo nyaya dzemhando dzakazowanikwa.
Pandakangocheka chikamu chezvikamu zvemavhidhiyo, huremu hombe hwakadonha kubva pamafudzi angu. Ini ndakanga ndisingachafaniri kunetseka kuti ndaizokanganwa metadata kana kusarudza iyo isiriyo yekubuda fomati. Kana kukanganisa kukauya gare gare, unogona kungogadzirisa script uye kudzokorora zvese.
Digitizing uye kugadzirisa vhidhiyo footage inongova hafu yehondo. Tichiri kuda kutsvaga sarudzo yakanakira kushambadza paInternet kuitira kuti hama dzese dzione vhidhiyo yemhuri iri mufomati iri nyore nekutenderera senge paYouTube.
Muchikamu chechipiri chechinyorwa, ini ndichatsanangura nzira yekumisikidza yakavhurika sosi midhiya server nemavhidhiyo ese emavhidhiyo, ayo anonditengera chete 77 cents pamwedzi.
