Txhais li cas "AI Green Screen" (thiab vim li cas nws tsis yog "kev tshem tawm keeb kwm yav dhau los") 🤖✨
Cov vijtsam ntsuab ib txwm siv lub keeb kwm yav dhau ntsuab khov kho + chroma keying.
AI ntsuab screen feem ntau yog kev faib ua feem (tus qauv kwv yees cov pixels twg yog "tus neeg" vs "tsis yog tus neeg"), thiab qee zaum matting (tus qauv kwv yees ib feem pob tshab nyob ib puag ncig cov ntsiab lus zoo li plaub hau, kev txav tsis meej, iav ntug, thiab lwm yam). Kev faib ua feem yog "kev txiav nyuaj." Matting yog qhov "qhov no zoo li lub neej tiag tiag". Hauv qab lub hood, ntau txoj hauv kev niaj hnub no tsim los ntawm cov tswv yim faib ua feem qhov twg lub kaw lus tsim lub ntsej muag pixel rau ib yam khoom / tus neeg [1].
Feem ntau koj yuav pom AI ntsuab screen tshwm sim li:

Teeb koj lub ntsej muag kom sib npaug (tsis txhob muaj duab ntxoov ntxoo uas faib koj lub qhov ntswg ua ob nrab)
-
Ntxiv lub teeb sib cais (lub teeb me me tom qab koj yog tus kws ua zaub mov hnia 👨🍳)
-
Tsis txhob muaj teeb pom kev sib xyaw (lub teeb ci ntsa iab ntawm qhov rais + lub teeb sov = kev tsis meej pem ntawm xim)
Cov kev xaiv tom qab uas tsis ua rau koj puas tsuaj
AI muaj teeb meem thaum koj keeb kwm yav dhau los yog:
-
tib xim li koj lub tsho

-
cov nto uas ci ntsa iab (iav, txee ci ntsa iab)
-
txav tej yam (kiv cua, cov ntxaij vab tshaus, cov tsiaj ua parkour 🐈)
Cov lus qhia txog khaub ncaws (yog tiag tiag)
-
Tsis txhob muaj cov kab txaij nyias nyias (lub nroog ci ntsa iab)
-
Tsis txhob muaj cov npoo uas tsis du (qee cov sweaters ua "kua zaub ntug")
-
Yog tias koj ua tau, xaiv ib lub sab saum toj uas muaj qhov sib txawv ntawm koj keeb kwm yav dhau los
Tsis muaj ib qho ntawm qhov no yog qhov yuav tsum tau ua, tab sis nws zoo li muab daim ntawv qhia rau AI es tsis txhob hais kom nws "nrhiav nws tawm."
Saib ze dua: plaub hau, tes, thiab lwm yam khoom AI nyiam ua kom puas tsuaj 🧑🦱✋
Yog tias AI ntsuab screen muaj tus neeg phem, nws yog cov plaub hau. Thiab cov ntiv tes. Thiab qee zaum lub mloog pob ntseg. Thiab qee zaum koj lub xub pwg tag nrho. Txias.
Cov lus qhia txog plaub hau
-
Ua kom cov ntug meej dua / cov ntug zoo dua yog tias muaj
-
Sim me ntsis ntawm cov plaub, tom qab ntawd rub rov qab lub ntsej muag nthuav dav (tsis sib xws, tab sis ua haujlwm)
-
Yog tias cov plaub hau hloov pob tshab, txo qhov mos mos thiab ua kom cov ntug sib txawv ntau dua
Tes + kev txav ceev
-
Yog tias koj lub cuab yeej txhawb nqa nws, ua kom lub sijhawm ruaj khov (txo qhov flicker)
-
Yog tias tes ploj mus, nthuav lub npog ntsej muag me ntsis thiab txo qhov ntsws
-
Rau kev co tes: tsis txhob ua kom pom kev tsis meej yog tias koj ua tau - zoo li cinematic, rhuav tshem cov ntaub thaiv qhov ncauj
Cov tsom iav thiab cov microphones
-
Cov tsom iav tuaj yeem ua rau muaj qhov txiav tsis zoo nyob ib puag ncig cov thav duab
-
Cov microphones thiab cov caj npab mic tuaj yeem ploj mus yog tias lawv nyias nyias
-
Kho: pleev xim rau cov chaw ntawd rov qab rau hauv lub npog ntsej muag (txhuam me me, them nyiaj ntau)
Qhov no zoo li siv txiab txiab los txiav cov ntoo cog ntoo. Tsis zoo nkauj heev. Tiam sis nws ua haujlwm tau zoo.
Saib ze dua: ua kom cov keeb kwm yav dhau zoo li ntuj - tsis zoo li koj tau muab lo rau ntawm daim ntawv xa ntawv 🖼️🧠
Qhov no yog ntu zais cia rau kev siv AI Green Screen yam tsis muaj qhov "floating cutout".
phim qhov kev xav ntawm lub koob yees duab
Yog koj lub koob yees duab ntse thiab koj keeb kwm yav dhau los yog daim duab qis-res, koj lub hlwb yuav pom tam sim ntawd.
Sim ua:
-
me ntsis blur rau ntawm keeb kwm yav dhau

-
Yog tias keeb kwm yav dhau kaj, tsa qhov kev pom ntawm tus neeg ib qho me me
Tsis txhob ua ntau dhau. Kho ntau dhau zoo li muab tshuaj pleev ntau dhau - tib neeg pom qhov laj thawj tsis raug 😵💫
Ntxiv ib qho duab ntxoov ntxoo me me
Ib daim duab ntxoov ntxoo mos mos tom qab/hauv qab koj pab lub hlwb lees txais qhov xwm txheej. Txawm tias yog ib qho cuav los xij.
Siv AI ntsuab screen nyob rau kev hu xov tooj thiab streaming (tsis muaj glitch halos) 🎙️📹
Cov duab ntsuab AI nyob xaiv dua li cov txheej txheem kho tom qab. Koj tsis tau txais daim ntawv hla thib ob.
Cov kev coj ua zoo tshaj plaws:
-
Siv lub teeb pem hauv ntej muaj zog (lub teeb ci ntsa iab pab tau)
-
Ua kom koj lub background zoo li qub
-
Tsis txhob zaum ze ntawm phab ntsa (muab kev sib cais)
-
Tsis txhob hnav cov xim uas sib xyaw rau ntawm phab ntsa
-
Txo qhov kev nrhiav pom lub koob yees duab tsis siv neeg (yog tias koj qhov kev teeb tsa tso cai)
Tsis tas li ntawd: cov cuab yeej siv tau tuaj yeem raug txwv los ntawm koj lub cuab yeej. Piv txwv li, Zoom tshaj tawm cov kev cai tshwj xeeb rau cov keeb kwm yav dhau virtual (thiab sau tseg tias keeb kwm yav dhau virtual tsis muaj lub vijtsam ntsuab tuaj yeem txwv qhov kev daws teeb meem tawm tshwj tsis yog tias koj ua tau raws li qee qhov kev cai) [3].
Thiab ntawm no yog ib qho lus qhia me me:
Yog tias lub ntsej muag ci ntsa iab, qee zaum kev txo qhov ntse ntawm lub koob yees duab yuav pab tau. Cov webcams uas ntse dhau lawm tsim cov npoo uas ua rau tsis meej pem txog kev faib ua ntu. Nws zoo li AI pom koj cov qauv thiab pib sib cav seb koj puas yog neeg lossis qos yaj ywm kib 🥔
Daim Ntawv Teev Cov Kev Teeb Meem - Kho sai thaum nws zoo li tsis zoo 😬🛠️
Yog tias koj qhov tshwm sim ntawm AI green screen zoo li tsis zoo, sim ua cov no raws li kev txiav txim:
-
Cov npoo ci ntsa iab

sib phim qhov kaj + sov so
-
ntxiv cov duab ntxoov ntxoo mos mos
-
ntxiv qhov tsis meej lossis cov noob sib xws
-
Qee zaum koj yuav kho nws thiab tseem xav tias nws "tsis tau tiav." Qhov ntawd yog ib txwm muaj. Koj lub qhov muag yuav xaiv sai sai - zoo li saj kua zaub thiab mam li hloov los ua tus neeg thuam zaub mov.
Ntxiv: txoj hauv kev "hybrid" thaum AI tsis txaus (aka qhov kev txav mus los ntawm cov neeg laus) 🧠🧩
Yog tias qhov AI txiav tawm yog 90% yog lawm , tsis txhob rov pib dua txhua yam. Muab cov kev kho sib dhos ua ke:
-
Siv lub ntsej muag AI ua lub hauv paus
-
Ntxiv ib daim ntaub nplaum uas yooj yim tshem tawm cov teeb meem
-
Pleev xim rau cov khoom nyias nyias (xws li caj npab mic, ntug tsom iav)
-
Ua kom lub flicker ruaj khov nrog cov cuab yeej temporal/consistency thaum muaj (piv txwv li, DaVinci Resolve's Magic Mask tooling siv "Consistency" los txo qhov suab nrov ntawm lub ntsej muag ib mus rau ob lub thav duab) [5]
Qhov no yog li cas "ib qho nias" dhau los ua "kev npaj txhij rau cov neeg siv khoom."
Kev ceev ntiag tug, kev coj ncaj ncees, thiab "kuv puas yuav tsum ua qhov no" (ua sai tab sis tseem ceeb) 🔐🧠
AI ntsuab screen tuaj yeem ua kev lom zem tsis muaj teeb meem ... lossis nws tuaj yeem tsis meej.
Ob peb cov lus qhia:
-
Tsis txhob hais tias koj nyob rau qhov chaw tiag tiag yog tias nws hloov lub ntsiab lus ntawm koj cov lus (kev ntseeg siab tseem ceeb)
-
Yog koj siv cov yeeb yaj kiab ntawm tus neeg siv khoom, khaws cov kev tso cai kom meej
-
Rau kev hu xov tooj ua pab pawg, ceev faj - qee qhov keeb kwm yav dhau los tuaj yeem cuam tshuam lossis ua yuam kev
-
Yog tias koj cov txheej txheem ua haujlwm upload cov yeeb yaj kiab mus rau lub tshuab ua haujlwm huab, kho nws zoo li cov ntaub ntawv rhiab heev (vim tias nws yuav yog)
Kuv tsis tau hais tias "tsis txhob ua li ntawd." Kuv hais tias ua li ib tug neeg laus uas xauv lawv lub qhov rooj pem hauv ntej. Qhov ntawd feem ntau yuav laus zuj zus.
Cov ntsiab lus tseem ceeb ntawm kev siv AI Green Screen 🟩✅
