Tau yim xyoo dhau los no, kuv tau tsiv lub thawv ntawm cov yeeb yaj kiab no mus rau plaub qhov sib txawv thiab ib lub tsev. Tsev neeg cov yeeb yaj kiab los ntawm kuv thaum yau.
Tom qab dhau 600 teev ntawm kev ua haujlwm, kuv thaum kawg tau muab lawv digitized thiab teeb tsa kom zoo kom cov kab xev pov tseg.
Ntawm no yog qhov footage zoo li tam sim no:
Tag nrho tsev neeg cov yeeb yaj duab yog digitized thiab muaj rau saib los ntawm ib tug private media server
Qhov no ua rau 513 tus kheej cov yeeb yaj kiab. Txhua tus muaj lub npe, lus piav qhia, hnub tim kaw, cim npe rau txhua tus neeg koom nrog qhia hnub nyoog thaum lub sijhawm kaw. Txhua yam yog hosted ntawm tus neeg siv xov xwm ntiag tug uas tsuas yog cov neeg hauv tsev neeg tau nkag mus, thiab hosting nqi tsawg dua $ 1 ib hlis.
Kab lus no qhia koj txhua yam uas kuv tau ua, vim li cas nws thiaj li siv yim xyoo kom mus txog qhov ntawd - thiab yuav ua li cas kom ua tiav qhov txiaj ntsig zoo sib xws yooj yim dua thiab sai dua.
Thawj qhov kev sim siab
Nyob ib ncig ntawm 2010, kuv niam yuav ib co VHS rau DVD converter thiab khiav tag nrho peb cov yeeb yaj duab hauv tsev los ntawm nws.
Original DVDs uas Niam sau tseg (tsis paub tias muaj dab tsi tshwm sim rau cov ntawv uas ploj lawm)
Qhov teeb meem yog tias niam tsuas yog ua ib daim DVD. Txhua tus txheeb ze nyob hauv ntau lub xeev, yog li nws tsis yooj yim kom dhau lub disks nyob ib puag ncig.
Xyoo 2012, kuv tus muam muab DVDs rau kuv. Kuv theej cov ntaub ntawv video thiab upload txhua yam rau huab cia. Teeb meem daws tau!
DVD rips ntawm tsev neeg cov yeeb yaj duab rau Google huab cia
Ob peb lub lis piam tom qab kuv nug seb puas muaj leej twg tau saib daim kab xev. Nws muab tawm tias tsis muaj leej twg saib. Txawm kuv tsis tau saib. Nyob rau hauv lub era ntawm YouTube, nws yog ruam mus download tau peb-teev cov ntaub ntawv ntawm tsis paub cov ntsiab lus nyob rau hauv kev tshawb fawb ntawm nthuav footage.
Tsuas yog kuv niam tau zoo siab: "Zoo heev," nws hais tias, "Tam sim no peb puas tuaj yeem muab tag nrho cov ntaub ntawv no pov tseg?"
Aw-oh. Qhov no yog ib lo lus nug txaus ntshai. Yuav ua li cas yog tias peb plam qee qhov kev nkag? Yuav ua li cas yog tias tapes yuav digitized ntawm zoo dua? Yuav ua li cas yog tias cov ntawv sau muaj cov ntaub ntawv tseem ceeb?
Kuv ib txwm tsis xis nyob muab pov tseg cov thawj coj mus txog thaum kuv paub tseeb tias cov yeeb yaj kiab tau theej nrog qhov ua tau zoo tshaj plaws. Yog li ntawd, kuv yuav tsum tau ua qhov teeb meem kuv tus kheej.
Kuv tsis paub dab tsi kuv tau txais kuv tus kheej rau hauv.
Tsis suab nyuaj
Yog tias koj tsis nkag siab tias vim li cas nws coj kuv yim xyoo thiab ntau pua teev, kuv tsis liam koj. Kuv kuj xav tias txhua yam yuav yooj yim.
Nov yog qhov txheej txheem digitization zoo li thaum pib mus rau qhov kawg:
Ntau precisely, qhov no yog li cas nws zoo li nyob rau hauv txoj kev xav. Nov yog li cas nws tau tshwm sim hauv kev xyaum:
Feem ntau ntawm lub sijhawm tau siv rov ua haujlwm dua yam uas twb tau ua lawm. Kuv yuav ua tiav ib theem, thiab tom qab ib lossis ob theem kuv yuav pom qee qhov tsis zoo hauv cov txheej txheem. Kuv yuav tsum rov qab ua dua. Piv txwv li, kuv coj 20 tapes ntawm video ua ntej kuv paub hais tias lub suab yog me ntsis tawm ntawm sync. Los yog, tom qab ob peb lub lis piam ntawm kev kho, kuv pom tias kuv tau exporting ib tug yees duab nyob rau hauv ib hom ntawv uas tsis txhawb streaming nyob rau hauv Internet.
Txhawm rau khaws cov neeg nyeem kev huv, kuv tab tom nthuav tawm cov txheej txheem zoo li nws tau txav mus rau pem hauv ntej, kom tsis txhob yuam kom koj dhia rov qab thiab rov ua txhua yam, raws li kuv yuav tsum tau ua.
Kauj ruam 1: Nthuav Video
Zoo, cia peb rov qab mus rau xyoo 2012. Niam yeej xav muab daim kab xev uas nws tau khaws cia rau nees nkaum xyoo, yog li thaum peb xub ntsib, nws tam sim ntawd muab ib lub thawv loj loj rau kuv. Yog li pib kuv qhov kev tshawb nrhiav digitization.
Txoj kev daws teeb meem yog los tso siab rau txoj haujlwm rau cov kws tshaj lij. Ntau lub tuam txhab tau koom nrog digitization, thiab qee qhov tshwj xeeb hauv kev yees duab hauv tsev.
Tab sis kuv zoo nkauj tsis pub leej twg paub, thiab kuv tsis xav kom cov neeg txawv saib peb tsev neeg cov yeeb yaj kiab ntawm peb lub sijhawm sib raug zoo, suav nrog kuv qhov kev cob qhia potty (thaum muaj hnub nyoog tsim nyog; tsis muaj dab tsi txawv!). Thiab kuv kuj xav tias tsis muaj dab tsi nyuab txog digitization.
Spoiler: Nws hloov tawm los ua nyuaj heev.
Thawj zaug sim ntawm video capture
Kuv txiv tseem muaj cov qub tsev neeg VCR, kuv thiaj thov kom nws khawb nws hauv qab daus rau tsev neeg noj hmo tom ntej. kuv yuav ntawm Amazon thiab tau mus ua haujlwm.
, thawj zaug ntawm ntau yam khoom siv A / V kuv tau yuav thaum lub sijhawm tshawb nrhiav ntau xyoo
Txhawm rau ua cov yeeb yaj kiab los ntawm USB capture ntaus ntawv, kuv siv qhov kev pab cuam VirtualDub; lub 2012 version yog me ntsis outdated, tab sis tsis tseem ceeb.
Cov duab hauv VirtualDub qhov kev pab cuam ntawm kuv nyeem ib phau ntawv rau kuv txiv thaum muaj plaub xyoos
Tawm tsam nrog suab distortion
Thaum kuv pib cov txheej txheem editing, kuv pom me ntsis tawm ntawm sync ntawm lub suab thiab video. Okay, tsis muaj teeb meem. Kuv tuaj yeem txav lub suab me ntsis.
Kaum feeb tom qab nws tawm ntawm sync dua. Puas yog kuv tsis txav nws txaus thawj zaug?
Nws maj mam dawned rau kuv tias lub suab thiab yees duab tsis yog tawm ntawm sync, lawv tau raug kaw ntawm qhov sib txawv ceev. Nyob rau hauv tag nrho cov kab xev lawv diverge ntau thiab ntau. Txhawm rau sync, kuv yuav tsum tau kho lub suab manually txhua ob peb feeb.
Yog tias koj qhov teeb tsa captures suab thiab yees duab ntawm tus nqi sib txawv, ces qhov kev daws teeb meem nkaus xwb yog los kho lub suab txhua ob peb feeb.
Koj puas tuaj yeem xav tias nws nyuaj npaum li cas kom paub qhov txawv ntawm lub suab 10 milliseconds ua ntej lossis 10 milliseconds tom qab? Nws nyuaj heev! Txiav txim rau koj tus kheej.
Hauv daim vis dis aus no kuv tab tom ua si nrog kuv tus neeg pluag, tus neeg mob miv, uas nws lub npe hu ua Black Magic. Lub suab yog me ntsis tawm ntawm sync. Txiav txim siab seb nws puas yog ua ntej ntawm daim duab lossis tom qab scenes?
Piv txwv ntawm ib daim vis dis aus nrog cov suab tsis sib xws thiab cov duab
Lub sijhawm no Black Magic jumps, ib feem qeeb qeeb tsib zaug:
Tawm ntawm sync ntawm suab thiab duab, tsib zaug qeeb
Teb: Lub suab tuaj nrog ncua ntawm ob peb milliseconds.
Tej zaum siv ib puas duas las es tsis txhob ntau pua teev ntawm tus kheej lub sij hawm?
Kev kho lub suab ib leeg yuav tsum tau ntau teev ntawm tedious, maddening ua hauj lwm. Nws thiaj li tshwm sim rau kuv tias kuv tuaj yeem zam lub desync los ntawm kev siv cov cuab yeej zoo dua, kim dua video capture. Tom qab qee qhov kev tshawb fawb kuv yuav ib qho tshiab ntawm Amazon:
Kuv zaum ob sim yuav
Txawm nrog lub cuab yeej tshiab, qhov tawm ntawm sync tsis tau ploj mus.
VCR nrog "super" ua ntej
Tej zaum qhov teeb meem yog nrog VCR. Ntawm lawv tau hais tias yuav tsis muaj kev sib koom ua ke ntawm VCR nrog "lub sijhawm hloov kho" (TBC), txoj haujlwm no muaj nyob rau txhua tus Super VHS (S-VHS) VCRs.
Zoo, tau kawg! Vim li cas kuv thiaj thab nrog qhov ruam no? zoo tib yam VCR, thaum muaj ΡΡΠΏΠ΅Ρ-VCR uas daws qhov teeb meem?
Tsis muaj leej twg ua S-VHS VCRs ntxiv lawm, tab sis lawv tseem muaj nyob hauv eBay. Rau $179 Kuv yuav JVC SR-V10U, uas zoo li ua haujlwm zoo rau VHS digitization:
Vintage JVC SR-V10U VCR uas kuv yuav ntawm eBay rau $179
Tus "super" video recorder tuaj txog hauv kev xa ntawv. Tom qab ob peb lub hlis ntawm kev tawm tsam nrog lub suab tawm ntawm sync, kuv zoo siab heev uas muaj cov cuab yeej uas yuav daws tau tag nrho kuv cov teeb meem.
Kuv qhib lub thawv, txuas txhua yam, tab sis lub suab tseem kaw ntawm qhov sib txawv ceev. Eh.
Kev tshawb nrhiav nkees, kev daws teeb meem thiab ntau xyoo ntawm kev tawm tsam
Kuv pib kuv qhov kev sim tsis muaj zog ntawm kev daws teeb meem. Nws mob siab rau saib. Txhua zaus kuv rub tawm tag nrho cov cuab yeej los ntawm lub txee dai khaub ncaws, nkag rau hauv kuv lub hauv caug tom qab lub desktop txuas txhua yam, sim ntes cov yeeb yaj kiab - thiab rov saib dua tias tsis muaj dab tsi ua haujlwm.
Yog li kuv thiaj tuaj hla lub rooj sib tham random post los ntawm 2008, uas hais txog kev txhim kho qee tus neeg tsav tsheb txawv teb chaws Suav tsis muaj npe ... Qhov no yog lub tswv yim txaus ntshai, tab sis kuv xav tau. Txawm li cas los xij, nws tsis pab.
Kuv sim cov kev pab cuam digitizing sib txawv. Yuav los ntxuav lub taub hau sib nqus ntawm VCR. Yuav . Tsis muaj dab tsi pab.
Kuv tau tso tseg tsis tu ncua, muab txhua yam tawm thiab zais cov cuab yeej hauv lub txee rau ob peb hlis ntxiv.
Peb tso tseg thiab muab cov kab xev rau cov kws tshaj lij
Nws yog 2018. Kuv tau tsiv VHS tapes thiab tons ntawm cov cuab yeej mus rau plaub qhov sib txawv thiab tab tom yuav tsiv tawm ntawm New York mus rau Massachusetts. Kuv nrhiav tsis tau lub zog los nqa lawv dua vim kuv twb paub lawm tias kuv yuav tsis ua tiav qhov project no ntawm kuv tus kheej.
Kuv nug tsev neeg seb puas muaj peev xwm coj cov kab xev mus rau lub tuam txhab digitization. Hmoov zoo, tsis muaj leej twg tawm tsam - txhua tus xav pom cov ntawv kaw dua.
Π―: Tab sis qhov ntawd txhais tau tias qee lub tuam txhab yuav nkag mus rau tag nrho peb cov yeeb yaj kiab hauv tsev. Nws puas haum koj?
Muam: Kuv tsis muab damn. Koj tsuas yog ib leeg txhawj txog qhov no. Tos, yog li koj tuaj yeem them tus neeg ua ntej?
Π―: Aw-uh...
Digitization ntawm tag nrho 45 tapes raug nqi $750. Nws zoo nkaus li kim, tab sis los ntawm qhov ntawd kuv yuav tau them ib yam dab tsi kom tsis txhob cuam tshuam nrog cov cuab yeej no ntxiv lawm.
Thaum lawv xa cov ntaub ntawv, video zoo yog twv yuav raug hu zoo dua. Hauv kuv cov thav ntawv, kev cuam tshuam ib txwm pom ntawm cov npoo ntawm tus ncej, tab sis cov kws tshaj lij digitized txhua yam yam tsis muaj kev cuam tshuam txhua. Qhov tseem ceeb tshaj plaws yog lub suab thiab video tau zoo kawg nkaus synchronized.
Nov yog ib daim vis dis aus sib piv cov kws tshaj lij digitization thiab kuv qhov kev sim hauv tsev:
Kev sib piv ntawm cov kws tshaj lij thiab hauv tsev digitization hauv video uas kuv niam ua yeeb yaj kiab kuv thawj zaug ntawm kev ua haujlwm
Kauj ruam 2: Kho kom raug
Thaum ua yeeb yaj kiab hauv tsev, kwv yees li 90% ntawm cov khoom siv tho txawv, 8% yog qhov nthuav, thiab 2% yog amazing. Tom qab digitization, koj tseem muaj ntau txoj haujlwm ua.
Hloov kho hauv Adobe Premiere
Ntawm VHS daim kab xev, cov kwj ntawm cov yeeb yaj kiab ntev yog sib cuam tshuam nrog cov seem dawb paug. Txhawm rau hloov daim kab xev, koj yuav tsum txiav txim siab qhov twg txhua qhov clip pib thiab xaus.
Rau kev kho, Kuv siv Adobe Premiere Elements, uas raug nqi tsawg dua $ 100 rau ib daim ntawv tso cai tas mus li. Nws qhov tseem ceeb tshaj plaws yog qhov scalable ncua sij hawm. Nws cia koj sai sai nrhiav cov ciam teb ntawm ib tug scene thiab ces zoom nyob rau hauv kom pom lub meej video ncej qhov twg clip pib los yog xaus.
Lub Sijhawm Tseem Ceeb nrog Zoom hauv Adobe Premiere Elements
Qhov teeb meem nrog Premiere yog tias cov txheej txheem yuav tsum tau siv zog tas li, tab sis digitization thiab xa tawm siv sijhawm ntev. Nov yog kuv qhov kev ua ntu zus:
- Qhib cov ntaub ntawv nyoos uas muaj 30-120 feeb ntawm video.
- Kos cov ciam teb ntawm ib tus kheej clip.
- Export clip.
- Tos 2-15 feeb rau kev xa tawm kom tiav.
- Rov ua cov kauj ruam 2-4 kom txog thaum koj khiav tawm ntawm daim kab xev.
Kev tos ntev txhais tau hais tias kuv tau hloov pauv ntawm kev kho video thiab lwm yam haujlwm, hloov kuv txoj kev xav rov qab mus rau ob peb teev.
Lwm drawback yog tsis-reproducibility. Kho qhov yuam kev me me yuav luag nyuaj li ua txhua yam los ntawm kos. Qhov no ua rau kuv nyuaj siab thaum nws los tshaj tawm cov yeeb yaj kiab. Tsuas yog tom qab ntawd kuv puas paub tias txhawm rau txhawm rau kwj hauv Is Taws Nem, nws yog qhov yuav tsum tau pib xa cov yees duab mus rau hom ntawv uas web browsers ib txwm txhawb nqa. Kuv tau ntsib nrog kev xaiv: rov pib dua cov txheej txheem tedious ntawm exporting pua pua ntawm clips, los yog rov encode cov yeeb yaj duab exported rau lwm hom ntawv nrog txo zoo.
Kho kom raug automation
Tom qab siv sijhawm ntau los ua haujlwm phau ntawv, kuv xav paub tias AI tuaj yeem siv rau ntawm no li cas. Kev txheeb xyuas cov ciam teb clip zoo li yog ib txoj haujlwm tsim nyog rau kev kawm tshuab. Kuv paub tias qhov tseeb yuav tsis zoo tag nrho, tab sis cia nws ua yam tsawg 80% ntawm txoj haujlwm thiab kuv yuav kho qhov kawg 20%.
Kuv twb tau sim nrog ib lub cuab yeej hu ua , uas txheeb xyuas cov ntaub ntawv video thiab muab sijhawm teem sijhawm qhov chaw hloov pauv tshwm sim:

...Cov cuab yeej tau qhia qhov tseeb txog li 80%, tab sis kev sim nws ua haujlwm tau siv sijhawm ntau dua li nws tau cawm. Txawm li cas los xij, pyscenedetect tau ua ib qho kev tshawb pom tseem ceeb tshaj plaws rau tag nrho qhov project: nrhiav pom thaj tsam thaj tsam thiab xa tawm cov clips yog cov haujlwm tshwj xeeb.
Kuv nco qab tias kuv yog ib tug programmer
Txog tam sim no, kuv xav tias txhua yam kuv tau ua hauv Adobe Premiere yog "kev hloov kho." Txiav cov clips los ntawm cov duab nyoos zoo li inextricably txuas mus nrhiav clip ciam teb, vim hais tias yog li cas Premiere nthuav qhia txoj hauj lwm. Thaum pyscenedetect luam tawm lub rooj metadata, nws ua rau kuv paub tias kuv tuaj yeem cais qhov kev tshawb fawb los ntawm cov video export. Nws yog ib qho kev tawg.
Yog vim li cas kho tau tedious thiab siv sij hawm yog vim kuv yuav tsum tau tos rau Premiere export txhua clip. Yog tias kuv tau kaw cov metadata hauv daim ntawv nthuav qhia thiab sau ib tsab ntawv uas tau xa tawm cov yeeb yaj kiab, cov txheej txheem kho yuav tau ya los ntawm.
Tsis tas li ntawd, cov ntawv nthuav qhia tau nthuav dav heev ntawm cov metadata. Thaum pib, kuv crammed metadata rau hauv cov ntaub ntawv npe, tab sis qhov no txwv nws. Muaj ib daim ntawv nthuav qhia tag nrho tso cai rau kuv sau cov ntaub ntawv ntau ntxiv txog qhov clip, xws li leej twg nyob hauv nws, thaum nws raug kaw, thiab lwm yam ntaub ntawv kuv xav qhia thaum lub sijhawm yees duab.
Ib daim ntawv loj loj nrog cov metadata txog kuv cov yeeb yaj kiab hauv tsev
Tom qab ntawd kuv tuaj yeem siv cov metadata no ntxiv cov ntaub ntawv rau cov clips, xws li hnub nyoog pes tsawg peb txhua tus thiab cov lus piav qhia ntxaws txog dab tsi tshwm sim hauv clip.
Spreadsheet functionality tso cai rau koj sau cov ntaub ntawv metadata, uas muab cov ntaub ntawv ntau ntxiv txog koj cov clips thiab ua rau lawv yooj yim mus saib
Kev vam meej ntawm kev daws teeb meem
Muaj cov ntawv sau, kuv sau , uas txiav cov yeeb yaj kiab nyoos rau hauv cov yeeb yaj kiab raws li cov ntaub ntawv CSV.
Ntawm no yog ib daim ntawv teev nws zoo li hauv kev nqis tes ua:
Los ntawm qhov no kuv tau siv pua pua teev, tediously xaiv clip ciam teb nyob rau hauv Premiere, nias export, tos ob peb feeb kom tiav, thiab ces pib dua tag nrho. Tsis tas li ntawd xwb, tab sis cov txheej txheem tau rov ua dua ob peb zaug ntawm tib lub clips thaum muaj teeb meem zoo tom qab pom.
Thaum kuv automated qhov txiav mus rau hauv clips, ib tug loj loj luj tau nqa tawm ntawm kuv lub xub pwg nyom. Tsis yog kuv yuav tsum txhawj xeeb txog kev tsis nco qab metadata lossis xaiv cov ntawv tso zis tsis raug. Yog tias qhov yuam kev tshwm sim tom qab, koj tuaj yeem kho cov ntawv thiab rov ua txhua yam.
Digitizing thiab kho cov ntaub ntawv video tsuas yog ib nrab ntawm kev sib ntaus sib tua. Peb tseem yuav tau nrhiav txoj hauv kev yooj yim rau kev tshaj tawm hauv Is Taws Nem kom txhua tus txheeb ze tuaj yeem saib tsev neeg cov yeeb yaj kiab hauv hom ntawv yooj yim nrog streaming zoo li hauv YouTube.
Nyob rau hauv qhov thib ob ntawm tsab xov xwm, kuv yuav qhia rau koj nyob rau hauv kom meej yuav ua li cas los tsim ib tug qhib qhov chaw tawm neeg rau zaub mov nrog tag nrho cov video clips, uas tus nqi kuv tsuas yog 77 xees ib hlis.
