M’zaka zisanu ndi zitatu zapitazi, ndasamutsa bokosi la matepi avidiyo ili m’zipinda zinayi zosiyanasiyana ndi nyumba imodzi. Makanema apabanja kuyambira ndili mwana.
Nditagwira ntchito kwa maola oposa 600, ndinawalemba pakompyuta n’kuwakonza bwinobwino kuti makasetiwo atayidwe.
Nazi momwe chithunzichi chikuwonekera:
Makanema onse am'banja amasungidwa pakompyuta ndipo amapezeka kuti awonedwe kuchokera pa seva yachinsinsi
Izi zidapangitsa kuti pakhale makanema okwana 513. Aliyense ali ndi mutu, kufotokozera, tsiku lojambulira, ma tag kwa onse omwe atenga nawo mbali, akuwonetsa zaka panthawi yojambulira. Chilichonse chili pa seva yachinsinsi yomwe ndi achibale okha omwe ali ndi mwayi wopeza, ndipo kuchititsa kumawononga ndalama zosakwana $ 1 pamwezi.
Nkhaniyi ikukamba za zonse zomwe ndachita, chifukwa chake zinatenga zaka zisanu ndi zitatu, komanso momwe mungakwaniritsire zotsatira zomwezo mosavuta komanso mofulumira.
Kuyesera koyamba kopanda nzeru
Cha m'ma 2010, amayi anga adagula mtundu wina wa VHS kupita ku DVD converter ndikuyendetsa makanema athu onse apanyumba.
Ma DVD oyambilira omwe amayi adajambulitsa (sindikudziwa zomwe zidachitika ndi zilembo zomwe zidasowa)
Vuto ndilakuti, Amayi adangopanga ma DVD amodzi okha. Achibale onse amakhala m'maboma osiyanasiyana, kotero zinali zovuta kudutsa ma disks mozungulira.
Mu 2012, mlongo wanga anandipatsa ma DVD amenewa. Ndidakopera mafayilo amakanema ndikuyika chilichonse kumalo osungira mitambo. Vuto lathetsedwa!
Ma DVD amang'amba mavidiyo abanja mu Google Cloud yosungirako
Masabata angapo pambuyo pake ndinafunsa ngati aliyense anali atawona matepiwo. Zinapezeka kuti palibe amene ankaona. Sindinayang'ane nkomwe. M'nthawi ya YouTube, kutsitsa mafayilo a maola atatu azinthu zosadziwika posaka zithunzi zosangalatsa ndizopusa.
Amayi okha ndiwo anakondwera: “Zabwino,” iye anatero, “tsopano kodi potsirizira pake tingataye makaseti onsewa?”
O-o. Ili ndi funso loyipa. Bwanji ngati taphonya zolemba zina? Nanga bwanji ngati matepi atha kusinthidwa kukhala apamwamba kwambiri? Nanga bwanji ngati zilembozo zili ndi mfundo zofunika?
Nthawi zonse ndimakhala womasuka kutaya zoyambira mpaka zitatsimikizika kuti vidiyoyo idakopedwa mwapamwamba kwambiri. Chifukwa chake, ndinayenera kupita ku bizinesi.
Sindinkadziwa n’komwe zimene ndinkalowera.
Sizikumveka zolimba
Ngati simukumvetsa chifukwa chake zinanditengera zaka zisanu ndi zitatu ndi maola mazana ambiri, sindikukuimbani mlandu. Ndinaganizanso kuti zingakhale zophweka.
Izi ndi zomwe ndondomeko ya digito imawonekera kuyambira koyambira mpaka kumapeto:
Kunena zowona, umu ndi momwe zimawonekera m'malingaliro. Umu ndi momwe zidakhalira pochita:
Nthawi zambiri ankathera kukonzanso zomwe zinali zitachitidwa kale. Ndinamaliza gawo limodzi, ndipo pambuyo pa gawo limodzi kapena awiri ndinapeza zolakwika zamtundu wina. Ndinayenera kubwerera ndi kukachitanso. Mwachitsanzo, ndidawombera kanema kuchokera pamatepi 20 ndisanazindikire kuti mawuwo anali osagwirizana pang'ono. Kapena patatha milungu ingapo ndikukonza, ndidapeza kuti ndikutumiza kanema mumtundu womwe sugwirizana ndikusakatula pa intaneti.
Kuti ndipulumutse owerenga kukhala oganiza bwino, ndikuyika ndondomekoyi ngati ikupita patsogolo mwadongosolo kuti musamangodumphira mmbuyo ndikubwereza zonse, monga momwe ndimayenera kuchitira.
Gawo 1 Jambulani kanema
Chabwino, kubwerera ku 2012. Amayi ankafunadi kutaya makaseti omwe anasunga kwa zaka makumi awiri, kotero pamene tinakumana koyamba, nthawi yomweyo anandipatsa makatoni aakulu. Apa ndinayamba kufunafuna kwanga digito.
Chosankha chodziwikiratu chinali kupereka ntchitoyo kwa akatswiri. Makampani ambiri akupanga digito, ndipo ena amakhala makamaka pamavidiyo apanyumba.
Koma sindimakonda zachinsinsi ndipo sindinkafuna kuti anthu osawadziwa aziwonera kanema wabanja lathu ndi nthawi zapamtima pa moyo wanga, kuphatikiza kuphunzitsidwa kwanga (pazaka zoyenera; palibe chachilendo!). Ndipo ndinaganizanso kuti palibe zovuta mu digito.
Spoiler: zidakhala zovuta kwambiri.
Kuyesera koyamba kujambula kanema
Bambo anga anali adakali ndi VCR yakale ya banjalo, chotero ndinawapempha kuti aifukule m’chipinda chapansi kaamba ka chakudya chamadzulo chotsatira. Ndinagula pa Amazon ndikuyamba bizinesi.
, zida zoyamba mwa zida zambiri za A/V zomwe ndidagula pazaka zambiri
Pokonza kanema ku USB adani chipangizo, Ndinagwiritsa ntchito VirtualDub pulogalamu, ndi 2012 Baibulo ndi pang'ono akale, koma osati ovuta.
Mafelemu mu pulogalamu VirtualDub, pamene ndinawerenga buku kwa bambo anga ali ndi zaka zinayi
Kuukira ndi kusokoneza phokoso
Nditayamba kusintha, ndidawona kusalunzanitsa pang'ono pakati pa audio ndi kanema. Chabwino, palibe vuto. Ndikhoza kusuntha phokoso pang'ono.
Mphindi khumi pambuyo pake, adasiya kugwirizananso. Kodi ndinasuntha pang'ono koyamba?
Pang'onopang'ono ndinazindikira kuti zomvera ndi makanema sizingolumikizana, zimajambulidwa pa liwiro losiyana. Mu tepi yonse, iwo amasiyana mochulukira. Kuti ndilumikize, ndimayenera kusintha mawuwo mphindi zingapo zilizonse.
Ngati khwekhwe lanu lijambulitsa zomvera ndi makanema pamitengo yosiyana, ndiye kuti yankho lokha ndikuwongolera pamanja mphindi zochepa zilizonse.
Kodi mungaganizire momwe zimavutira kusiyanitsa mawu 10 milliseconds kale kapena 10 milliseconds pambuyo pake? Ndizovuta kwambiri! Weruzani nokha.
Muvidiyoyi, ndikusewera ndi mwana wanga wosauka, woleza mtima, yemwe dzina lake ndi Black Magic. Phokosoli silikulumikizana pang'ono. Dziwani ngati ili patsogolo pa chithunzi kapena kwachedwa?
Chitsanzo cha kanema kanema wokhala ndi mawu ndi chithunzi chosalunzanitsidwa
Pakadali pano, Black Magic idalumpha, chidutswa chokhala ndi kutsika kasanu:
Phokoso ndi chithunzi sizikulumikizana, pang'onopang'ono kasanu
Yankhani: Phokoso limabwera ndi kuchedwa kwa ma milliseconds ochepa.
Mwina ndalama zowonjezera zana m'malo mwa maola mazana a nthawi yanu?
Kuwongolera mawu kokhako kunafuna maola ambiri a ntchito yotopetsa, yochititsa misala. Pambuyo pake zidandifikira kuti desync itha kupewedwa pogwiritsa ntchito chida chabwinoko komanso chokwera mtengo chojambulira makanema. Nditafufuza, ndidagula ina pa Amazon:
Kuyesera kwanga kwachiwiri kugula
Ngakhale ndi chipangizo chatsopano, desync sanazimiririke kulikonse.
VCR yokhala ndi mawu oyambira "wapamwamba"
Mwina vuto lili ndi VCR. Yambani zinanenedwa kuti sipadzakhala desynchronization pa VCR ndi "time-based corrector" (TBC), mbali iyi imapezeka pa ma VCR onse a Super VHS (S-VHS).
Chabwino, ndithudi! Bwanji ndasokoneza ndi opusa wamba VCR ikapezeka супер-VCR yomwe imathetsa vutoli?
Palibe amene amapanga S-VHS VCRs panonso, koma akupezekabe pa eBay. Kwa $ 179, ndidagula mtundu wa JVC SR-V10U, womwe ukuwoneka kuti ndi woyenera pa digito ya VHS:
Vintage JVC SR-V10U VCR Ndinagula pa eBay kwa $179
"Super" VCR idabwera pamakalata. Pambuyo pa miyezi ingapo ndikuvutika ndi mawu osalumikizana, ndinali wokondwa kuti panali zida zomwe zingathetse mavuto anga onse.
Ndinatsegula bokosilo, ndikugwirizanitsa chirichonse - koma phokoso linali lolembedwa pa liwiro losiyana. Eh.
Kusaka kotopetsa, kuthetsa mavuto ndi zaka zolimbana
Ndinayamba kuyesa kuthetsa mavuto. Zinali zowawa kupenyerera. Nthawi iliyonse ndikatulutsa zida zonse m'chipindamo, ndikukwawa pa mawondo anga kuseri kwa desktop kuti ndilumikizane ndi chilichonse, ndikuyesa kujambula kanema - ndikuwoneranso kuti palibe chomwe chikugwira ntchito.
Ndinakumana ndi positi yachisawawa kuchokera mu 2008 yokhudza kukhazikitsa dalaivala wina wachilendo wosasainidwa waku China... Ndi lingaliro loyipa, koma ndikusimidwa. Komabe, sanathandize.
Ndinayesa mapulogalamu osiyanasiyana a digito. Anagula kuyeretsa mitu ya maginito ya VCR. Anagula . Palibe chomwe chinathandiza.
Nthawi zonse ndinasiya, kumasula zonse, ndi kubisa zipangizozo m'chipinda chapansi kwa miyezi ingapo.
Perekani ndikupereka makaseti kwa akatswiri
Chaka cha 2018 chafika. Ndinasamutsa matepi a vidiyo ndi matani a zipangizo kuzungulira zipinda zinayi zosiyanasiyana ndipo ndinali pafupi kusamuka ku New York kupita ku Massachusetts. Sindinathe kupeza mphamvu zowatenganso, chifukwa ndinazindikira kale kuti sindidzamaliza ntchitoyi ndekha.
Ndidafunsa banjalo ngati angapereke makaseti ku kampani yopanga zida zamagetsi. Mwamwayi, palibe amene anatsutsa - aliyense ankafuna kuti awonenso zolembazo.
Я: Koma izi zikutanthauza kuti kampani ina ipeza makanema athu onse apanyumba. Kodi zikukuyenererani?
Mlongo: Inde, ndimasamala. Inu nokha muli ndi nkhawa. Dikirani, ndiye mukanangolipira munthu poyambirira?
Я: U-uh…
Kuyika pa digito makaseti onse 45 kumawononga $750. Zikuwoneka zodula, koma panthawiyo ndikadalipira chilichonse kuti ndisakhalenso ndi zida izi.
Pamene anapereka owona, kanema khalidwe ndithudi bwino. Pamafelemu anga, zosokoneza zinkawoneka nthawi zonse m'mphepete mwa chimango, koma akatswiri amajambula chilichonse popanda kusokoneza. Chofunika kwambiri, zomvera ndi makanema zimagwirizana bwino.
Nayi kanema wofanizira akatswiri a digito ndi zoyesayesa zanga zakunyumba:
Kuyerekeza kwaukadaulo komanso kopanga pakompyuta mu kanema komwe amayi amajambula kuyesa kwanga koyamba pakupanga mapulogalamu
Gawo 2. Kusintha
Mphukira zapakhomo, pafupifupi 90% yazinthu ndizotopetsa, 8% ndizosangalatsa, ndipo 2% ndizodabwitsa. Pambuyo pa digito, mudakali ndi ntchito yambiri yoti muchite.
Kusintha mu Adobe Premiere
Pakaseti ya VHS, mavidiyo amtundu wautali amalowetsedwa ndi zigawo zopanda kanthu. Kusintha tepi, muyenera kudziwa kumene kopanira aliyense akuyamba ndi kutha.
Pakusintha, ndidagwiritsa ntchito Adobe Premiere Elements, yomwe imawononga ndalama zosakwana $100 pachiphaso cha moyo wonse. Mbali yake yofunika kwambiri ndi nthawi yowonjezereka. Iwo amalola mwamsanga kupeza m'mphepete mwa zochitika ndiyeno mawonedwe mu kupeza yeniyeni kanema chimango kumene kopanira akuyamba kapena kutha.
Zofunikira zowonera nthawi mu Adobe Premiere Elements
Vuto loyamba ndi loti ndondomekoyi imafuna masitepe okhazikika, koma digitizing ndi kutumiza kunja kumatenga nthawi yaitali. Nayi mndandanda wanga wamachitidwe:
- Tsegulani fayilo yaiwisi yomwe ili ndi kanema wa mphindi 30-120.
- Chongani malire a munthu kopanira.
- Tumizani kopanira.
- Dikirani kwa mphindi 2-15 kuti kutumiza kumalize.
- Bwerezani masitepe 2-4 mpaka tepiyo itatha.
Kudikirira kwanthawi yayitali kumatanthauza kuti ndimasinthasintha nthawi zonse pakati pa kusintha kwamavidiyo ndi ntchito ina, ndikusintha chidwi changa mmbuyo ndi mtsogolo kwa maola ambiri.
Vuto lina linali kusabereka. Kukonza cholakwika chaching'ono kunali kovuta ngati kuyambira pachiyambi. Zinandikhudza kwambiri ndikayika vidiyo. Apa ndipamene ndinazindikira kuti kuti ndizitha kusuntha pa intaneti, kunali koyenera kutumiza kanemayo ku mtundu womwe asakatuli amathandizira. Ndinayang'anizana ndi kusankha: kuyambitsanso njira yotopetsa yotumizira mazana azithunzi, kapena sinthaninso makanema omwe adatumizidwa kumtundu wina wokhala ndi khalidwe lonyozeka.
Kusintha makina
Nditakhala nthawi yayitali pantchito yamanja, ndidadzifunsa ngati AI ingagwiritsidwe ntchito pano mwanjira ina. Kuzindikira malire a tatifupi kumawoneka ngati ntchito yoyenera yophunzirira makina. Ndinadziwa kuti kulondola sikungakhale kwangwiro, koma achite osachepera 80% ya ntchitoyo, ndipo ndidzakonza 20% yomaliza.
Ndinayesa chida chotchedwa , yomwe imagawa mafayilo amakanema ndikutulutsa zowonetsa nthawi pomwe kusintha kumachitika:

...Chidacho chidawonetsa kulondola pafupifupi 80%, koma kuyang'ana ntchito yake kunatenga nthawi yochulukirapo kuposa momwe idasungira. Komabe, pyscenedetect idapeza chimodzi mwazinthu zofunika kwambiri pantchito yonseyi: kutanthauzira malire azithunzi ndi zotumiza kunja ndi ntchito zosiyana.
Ndinakumbukira kuti ndine wopanga mapulogalamu
Mpaka pano, ndimaona zonse zomwe ndidachita mu Adobe Premiere kukhala "zosintha". Kudula tatifupi kuchokera ku mafelemu aiwisi kumawoneka kuti kumagwirizana ndikupeza malire a kanema, chifukwa ndi momwe Premiere adawonera ntchitoyi. Pamene pyscenedetect idasindikiza tebulo la metadata, idandipangitsa kuzindikira kuti nditha kulekanitsa kusaka kwazithunzi ndi kutumiza mavidiyo. Zinali zopambana.
Chifukwa chake kusintha kunali kotopetsa komanso kumatenga nthawi chifukwa ndimayenera kudikirira pomwe Premiere imatumiza kanema iliyonse. Ndikadati ndilembe metadata mu spreadsheet ndikulemba script yomwe imatumiza vidiyoyo yokha, njira yosinthira ingadutse.
Kuphatikiza apo, ma spreadsheets akulitsa kwambiri kuchuluka kwa metadata. Poyamba, ndimalowetsa metadata mu dzina la fayilo, koma izi zimawalepheretsa. Kukhala ndi spreadsheet yonse kunandilola kuti ndisanthule zambiri za clip, monga yemwe anali mmenemo, pamene idajambulidwa, ndi zina zilizonse zomwe ndikufuna kuwonetsa kanemayo ikawonetsedwa.
Chitsamba chachikulu chokhala ndi metadata yokhudza makanema akunyumba kwanga
Pambuyo pake, ndidatha kugwiritsa ntchito metadata iyi kuti ndiwonjezere zambiri pazithunzi, monga zaka zomwe tonse tinali nazo komanso kufotokozera mwatsatanetsatane zomwe zikuchitika pagawoli.
Magwiridwe a Spreadsheet amakulolani kuti mujambule metadata yomwe imapereka zambiri zokhudzana ndi tatifupi ndikupangitsa kuti muwone mosavuta
Kupambana kwa njira yodzichitira yokha
Pokhala ndi spreadsheets, ndinalemba , yomwe idadula vidiyo yaiwisi m'zigawo kutengera data ya CSV.
Izi ndi momwe zimawonekera pochita:
Panopa ndawononga mazana maola, kusankha movutikira malire azithunzi mu Premiere, kugunda kutumiza, kudikirira mphindi zingapo kuti ithe, kenako ndikuyambiranso. Osati zokhazo, ndondomekoyi idabwerezedwa kangapo pazigawo zomwezo pamene nkhani zabwino zidadziwika.
Nditangopanga gawo lodulirapo, chinthu chachikulu chinagwa paphewa langa. Sindinakhalenso ndi nkhawa kuti ndingayiwala metadata kapena kusankha mtundu wolakwika. Ngati cholakwika chikabwera pambuyo pake, mutha kungosintha script ndikubwereza chilichonse.
Digitizing ndi kusintha kanema kanema ndi theka la nkhondo. Tikufunikabe kupeza njira yabwino yosindikizira pa intaneti kuti achibale onse athe kuwonera kanema wabanja m'njira yabwino ndikukhamukira ngati pa YouTube.
Mu gawo lachiwiri la nkhaniyi, ndifotokoza mwatsatanetsatane momwe mungakhazikitsire seva yotsegulira media ndi makanema onse, zomwe zimanditengera masenti 77 okha pamwezi.
