Indlela yokusebenzisa i-AI Green Screen - uhlelo lokusebenza lwesinyathelo ngesinyathelo olugwema izinhlekelele eziningi 🧩🎬

Nansi indlela yokusebenza eyinhloko. Lena inguqulo "yemisebenzi empilweni yangempela".

Isinyathelo 1: Qala ngezithombe ezingcono kunalokho ocabanga ukuthi udinga 🎥

Ukuthanda ukufihla ubuso nge-AI:

• ukuhlukaniswa kwesihloko okucacile (wena vs isizinda)

• ukukhanya okuhle

• ukulungiswa okuphezulu

• ukufiphala kokunyakaza okuncane

Uma i-clip yakho imnyama futhi inobuhlalu, i-AI izoqagela imiphetho njengokungathi ibhekabheka phakathi kwemvula.

Isinyathelo 2: Khetha indlela yakho (ngesikhathi sangempela noma uhlele kamuva) ⏱️

• Isikhathi sangempela: sebenzisa ukushintshwa kwesizinda esibukhoma

• Hlela kamuva: sebenzisa i-AI masking kumugqa wesikhathi ukuze ukwazi ukulungisa amaphutha

Uma ikhwalithi ibalulekile, ukuhlela kuyaphumelela kamuva. Uma isivinini sibalulekile, kuyaphumelela ngesikhathi sangempela.

Isinyathelo 3: Sebenzisa ukuhlukaniswa / ukususwa kwesizinda 🟩

Amathuluzi amaningi ayibiza ngokuthi:

• ukususa ingemuva

• ukuhlukaniswa kwesihloko

• isikwele sesithombe

• "Imaski ye-AI" / "i-smart matte"

Yisebenzise kanye. Ungahluleli ngokushesha okukhulu. Yivumele icubungulwe ngokugcwele.

Isinyathelo 4: Hlanza imaski (yilapho ukubukeka "kobungcweti" kwenzeka khona) 🧼

Bheka izilawuli ezifana nalezi:

• umngcele woboya / ukuthambisa

• nciphisa / khulisa imaski

• umehluko womphetho

• susa ukungcola kwemibala / ukucindezela ukuchitheka

• imininingwane yezinwele / imiphetho emincane

• ukuphathwa kokufiphaza ukunyakaza / amathuluzi esikhashana

Isibonelo sokuthi izilawuli zokucwenga "zangempela" zibukeka kanjani: Ukuhamba komsebenzi kwe-After Effects' Roto Brush + Refine Matte kubiza ngokusobala ukucwenga imiphetho enemininingwane efana nezinwele, isinxephezelo sokufiphaza ukunyakaza, kanye nokususwa kombala onqenqemeni [2]. (Ukuhumusha: yebo, isofthiwe iyazi ukuthi izinwele ziyinhloko yokugcina.)

Isinyathelo 5: Engeza isizinda sakho esisha (bese usifanisa) 🌄

Lena yingxenye abantu abayigwemayo… bese bezibuza ukuthi kungani ibukeka njengeyamanga.

Ukufanisa:

• ukukhanya

• umehluko

• izinga lokushisa lombala (elifudumele vs elipholile)

• umbono (ungazifaki esithombeni sangemuva usuka ophahleni… ngaphandle kokuthi ufuna okungavamile)

Isinyathelo 6: Engeza isisekelo esincane 🧲

Ukuze uzizwe ungokoqobo, engeza:

• isithunzi esithambile ngaphansi/ngemuva kwakho

• ukufiphala okuncane kwangemuva uma ikhamera yakho ibukhali kuwe

• umsindo omncane/okusanhlamvu ukuhlanganisa izendlalelo

Ukuhlanzeka kakhulu kungabukeka njengestikha. Njengedekhali. Idekhali eqinisekile kakhulu.

Isinyathelo 7: Thumela ngendlela efanele (esobala noma ehlanganisiwe) 📦

Imiphumela evamile:

• Ividiyo yokugcina enesizinda esifakwe ngaphakathi

• Ividiyo yangemuva engabonakali (i-alpha) yokusetshenziswa kabusha

• I-matte yangaphambili (imaski emnyama/emhlophe) yokuhlanganisa

Uma uthumela ngaphandle nge-alpha ukuze uhlanganise ngokujulile, inketho ejwayelekile "ye-workhorse" yi- Apple ProRes 4444, esekela isiteshi se-alpha sekhwalithi ephezulu (iphepha elimhlophe le-ProRes lichaza isiteshi se-alpha esingenakulahlekelwa ngokwezibalo esifinyelela kuma-bits ayi-16) [4].

Ukubheka eduze: amathiphu okuqopha enza isikrini esiluhlaza se-AI sibukeke sisihle ngendlela engafanele 💡😎

Masibe neqiniso - i-AI akuyona yodwa into eyenza umsebenzi. Ukusetha kwakho kubalulekile.

Ukukhanyisa okusiza imodeli

• Khanyisa ubuso bakho ngokulinganayo (akukho sithunzi esinzima esihlukanisa ikhala lakho phakathi)

• Engeza isibani sokuhlukanisa (isibani esincane esingemuva kwakho siwukuqabula kompheki 👨🍳)

• Gwema ukukhanya okuxubile (ukukhanya kwelanga kwefasitela + isibani esifudumele = ukudideka kombala)

Ukukhetha kwangemuva okungakukhinyabezi

I-AI iyahlupheka lapho isizinda sakho si:

• umbala ofanayo nehembe lakho

• amaphethini amatasa (amashalofu ezincwadi angaba yingozi)

• izindawo ezikhanyayo (izibuko, amakhabethe acwebezelayo)

• izinto ezihambayo (abalandeli, izikrini, izilwane ezifuywayo zenza i-parkour 🐈)

Amathiphu ezingubo zokugqoka (yebo ngempela)

• Gwema imivimbo emincane kakhulu (idolobha elikhazimulayo)

• Gwema imiphetho ethambile (amanye amajezi aba “isobho elinomphetho”)

• Uma ukwazi, khetha ingaphezulu elinomehluko osuka ngemuva kwakho

Akukho kulokhu okudingekayo, kodwa kufana nokunikeza i-AI imephu esikhundleni sokuyitshela ukuthi “ithole.”

Ukubheka eduze: izinwele, izandla, nezinye izinto i-AI ithanda ukungcolisa 🧑🦱✋

Uma isikrini esiluhlaza se-AI sinobubi, izinwele. Neminwe. Futhi ngezinye izikhathi ama-headphone. Futhi ngezinye izikhathi lonke ihlombe lakho. Kuhle.

Amathiphu ezinwele

• Khulisa imininingwane yomphetho / imiphetho emincane uma ikhona

• Zama inani elincane lokufutha, bese udonsa imaski yokukhulisa (iphikisana nokuqonda, kodwa iyasebenza)

• Uma izinwele ziphenduka zikhanye, yehlisa ukuthamba futhi wandise umehluko womphetho

Izandla + ukunyakaza okusheshayo

• Uma ithuluzi lakho lisekela, yandisa ukuzinza kwesikhashana (kunciphisa ukufiphala)

• Uma izandla zinyamalala, yandisa imaski kancane bese unciphisa ukushwabana

• Ukuze uphakamise isandla: gwema ukufiphala kokunyakaza okunzima uma ungakwazi - kubukeka sengathi kufana ne-cinema, kuphula imaski

Izibuko namamakrofoni

• Izibuko zingabangela ukusika okungajwayelekile eduze kohlaka

• Ama-mics kanye nezingalo ze-mic zinganyamalala uma zincane

• Lungisa: penda lezo zindawo ngesandla uzibuyisele emaskini (umsebenzi omncane wokuxubha, inzuzo enkulu)

Le ngxenye ifana nokulungisa uthango ngesikele sokuphepha. Ayikhazimuli. Kodwa iyasebenza.

Ukubheka eduze: ukwenza izizinda zibukeke zemvelo - hhayi njengokungathi unamathiselwe ekhadini leposi 🖼️🧠

Lesi yisigaba esiyimfihlo sendlela yokusebenzisa i-AI Green Screen ngaphandle kwe-"floating cutout".

Qondanisa umuzwa wekhamera

Uma ikhamera yakho ibukhali futhi ingemuva lakho linesithombe esiphansi, ubuchopho bakho bubona ngokushesha.

Zama:

• Gcina ingemuva liyimfihlo

• Gwema ukuhlala eduze kakhulu nodonga (kwenza kube nokuhlukana)

• Ungagqoki imibala ehlangana nodonga

• Nciphisa ukuzingela ukuchayeka ngokuzenzakalela kwekhamera (uma ukusetha kwakho kukuvumela)

Futhi: amathuluzi abukhoma anganqunyelwa yidivayisi yakho. Isibonelo, i-Zoom ishicilela izidingo ezithile zesistimu zezizinda ezingokoqobo (futhi iphawula ukuthi izizinda ezingokoqobo ezingenayo isikrini esiluhlaza zingavala isinqumo esiphumayo ngaphandle kokuthi uhlangabezana nezidingo ezithile) [3].

Nasi icebiso elincane:
Uma imaski ikhanya, ngezinye izikhathi ukwehlisa ukucija kwekhamera kuyasiza. Ama-webcam abukhali kakhulu adala imiphetho elukhuni edida ukuhlukaniswa. Kufana nokuthi i-AI ibona uhlaka lwakho bese iqala ukuphikisana ngokuthi ungumuntu noma uyi-potato chip 🥔

Uhlu lokuhlola izinkinga - ukulungisa okusheshayo uma kubukeka kubi 😬🛠️

Uma umphumela wakho wesikrini esiluhlaza se-AI ubonakala ungafanele, zama lokhu ngokulandelana:

Umphumela obonisayo, osekelwe ekubekeni isikhathi ukuhlela kwesampula ezintathu ngaphambi nangemva kokusebenzisa lo msebenzi wokusebenza:

Ukushintsha ingemuva ngokuchofoza kanye kwathatha cishe imizuzu eyi-18 ukuze kukhiywe i-clip yemizuzu emi-3, kodwa kusadingeka kulungiswe kabusha ngenxa yokucwazimula kwamahlombe kanye neminwe enyamalalayo.

Ukuhamba komsebenzi okuhleliwe kuthathe cishe imizuzu engama-26 ngesiqephu esifanayo semizuzu emi-3, okuhlanganisa nokudlula kokuhlolwa kanye nokuhluzwa. Kodwa-ke, kunciphise amaphutha okumboza abonakalayo kusuka ezinkingeni eziyi-14 kuya ezinkingeni ezi-3 uma kuqhathaniswa nohlu olulula lokubuyekezwa lwamaphuzu ayi-10.

Kuvidiyo yesifundo yemizuzu eyi-12, lokho kusho ukuthi umhleli uchitha isikhathi eside ngaphambi kwesikhathi, kodwa ugwema umjikelezo wesibili ogcwele wokubuyekeza. Kulesi sibonelo, isikhathi sokuhlela nokubuyekeza sincipha sisuka cishe emahoreni ama-2 nemizuzu eyi-10 siye cishe ehoreni eli-1 nemizuzu engama-25 ngoba izinkinga ezimbalwa zibuya ngemva kokubuyekeza.

Ungakuhlola lokhu ngokwakho ngokubeka isikhathi sokuhlela kokuqala, ukubala amaphutha emaski abonakalayo, nokulandelela ukuthi zingaki izilungiso eziceliwe ngemva kokubuyekezwa.

Yini engase ihambe kabi

Ingozi enkulu ukwethemba ngokweqile i-AI cutout. Imaski ingabukeka ilungile ngobukhulu obujwayelekile, bese iwa lapho umethuli ehamba ngokushesha noma ephakamisa isandla eduze kobuso bakhe.

Amanye amaphutha avamile:

Ukusebenzisa isizinda esikhanya kakhulu kunesihloko

Ukwengeza izinwele eziningi kakhulu, okwenza izinwele zibukeke zinomusi

Ukukhohlwa ukugcina izinto ezincane njengezintambo zemakrofoni noma izingalo zezibuko

Ukuthumela ividiyo yokugcina ebhakiwe kuphela uma kudingeka inguqulo ecacile kamuva

Ukusebenzisa indawo esunguliwe eshintsha incazelo yevidiyo, njengokwenza ukuqoshwa kwasekhaya kubukeke sengathi kuqoshwe ehhovisi elingokoqobo, esitudiyo, noma endaweni yomcimbi

Iphasi lokubuyekezwa komuntu lisabalulekile. I-AI ingasusa ingemuva, kodwa ayikwazi njalo ukwahlulela ukuthi isigcawu sokugcina sizwakala siyiqiniso, sikholeka, noma sifanele izilaleli.

Ukudla okuwusizo

Kumavidiyo angathi sína, isikrini esiluhlaza se-AI sisebenza kahle kakhulu njengomsebenzi olawulwayo: hlola kuqala, vala imaski okwesibili, lungisa okwesithathu, bese uhlanganisa isihloko nesizinda esisha. Ukuhlolwa okwengeziwe kwemizuzu eyi-10 kuvame ukushibhile kunokulungisa ividiyo yonke egcwele izinwele ezikhazimulayo, izandla ezinyamalalayo, kanye nomphumela othi “kungani ngibukeka njengesitika?”.

Imibuzo Evame Ukubuzwa

Iyini isikrini esiluhlaza se-AI, futhi sihluke kanjani ekususweni kwesizinda okuvamile?

Isikrini esiluhlaza se-AI sivame ukusho ukuthi ithuluzi lenza ukuhlukaniswa (linquma ukuthi yimaphi amaphikseli “anguwe” uma kuqhathaniswa “akusikho wena”) futhi, ezimweni eziningi, ukugoqa (ukusingatha ukucaca okuyingxenye ezungeze izinwele, ukufiphaza kokunyakaza, kanye nemiphetho emincane). Ukususa ingemuva okulula kuvame ukuguquka kube ukugoqa okunzima, okungafundeka njengokufana nesitika. Ukugoqa kanye nokulungiswa kwemiphetho yikona okulisunduzela “kulokhu kungaba ngokoqobo.”

Ungayisebenzisa kanjani i-AI Green Screen ngaphandle kokuthola imiphetho ekhanyayo noma uhlaka olukhanyayo?

Qala ngezithombe ezenza umsebenzi womodeli ube lula: ukukhanya okuqinile ebusweni bakho, ukuhlukana okucacile nesizinda, kanye nokufiphala okuncane kokunyakaza. Ngemva kokusika kokuqala, ncika ezilawulini zokulungisa ezifana nokunciphisa/ukuthambisa, ukunciphisa/ukwandisa, ukuqhathanisa umkhawulo, kanye nanoma yiziphi izinketho zokuqina kwesikhathi. Qedela ngokufanisa umbala wangemuva kanye nokucija ukuze imiphetho yakho ingakhali ngokuthi “ukusikwa.”

Iyiphi indlela esheshayo yokuhlola ukuthi ukusethwa kwesikrini esiluhlaza se-AI kuzosebenza yini ngaphambi kokuqopha ividiyo ephelele?

Qopha isiqeshana sokuhlola esisheshayo semizuzwana eyi-10: khuluma nekhamera, uphakamise izandla zakho, bese ujika ikhanda ngokushesha. Sebenzisa isiqeshana, bese uhlola ku-zoom engu-200% ukuthi izinwele ziqhekekile, izandla ziyaqhekeka yini ngesikhathi sokunyakaza, ukucwazimula kwamahlombe, nokuthi izibuko noma imakrofoni kuyasinda yini. Uma yehluleka esivivinyweni, izohluleka kakhulu ekucabangeni kwakho "okubalulekile".

Ingabe kufanele ngisebenzise isikrini esiluhlaza se-AI sesikhathi sangempela noma umsebenzi wokuhlela kamuva?

Isikhathi sangempela sihle kakhulu uma udinga imiphumela esheshayo yezingcingo nokusakaza, kodwa asixoleli kangako ngoba akukho ukudlula kwesibili. Imisebenzi yokuhlela kamuva iyaphumelela uma ikhwalithi ibalulekile, njengoba ungalungisa imiphetho, ulungise ozimele bezinkinga, futhi ulungise ukucindezelwa nokuxutshwa kokuchitheka. Iphethini evamile yile: isikhathi sangempela sesivinini, ukuhlela kamuva kunoma yini ebhekene neklayenti.

Ngingenza kanjani izinwele zibukeke zemvelo ngesikrini esiluhlaza se-AI (hhayi njengokungathi ziyancibilika)?

Izinwele yilapho imaski ivame ukuphuka khona kuqala, ngakho-ke hlela ukucwenga. Funa "imiphetho emincane" noma izilawuli zemininingwane yezinwele, bese usebenzisa inani elincane loboya obuhambisana nokwandiswa/ukuncipha kwemaski ngokucophelela ukuze izinwele ezithambile zingaphenduki zibonakale. Uma ithuluzi linikeza ukususwa kombala onqenqemeni, lisebenzise ukuze izinwele zingatholi umbala wangemuva.

Kungani izandla, ukunyakaza okusheshayo, nezinto ezincane ziqhubeka zinyamalala ezinqumweni ze-AI?

Ukuhlukaniswa kwezingxenye kunzima ngokufiphala kokunyakaza kanye nemininingwane emincane njengeminwe, izingalo zemakrofoni, kanye nozimele bezibuko, ngakho imodeli ingazilahla noma ikhanye. Ukwandisa ukuzinza kwesikhashana noma izilungiselelo zokuvumelana kunganciphisa umsindo wohlaka olulodwa kuya kolubili, futhi ukunwetshwa okuncane kwemaski kungasiza ukugcina izandla ziqinile. Uma kusahluleka, ukupenda/ukuthinta ngesandla amabhulashi kulezo zindawo kuvame ukuba yindlela esheshayo yokulungisa.

Ngingenza kanjani ukuthi ingemuva elishintshiwe libukeke likholeka esikhundleni sokuthi “linamathiselwe”?

Imiphumela eminingi "engamanga" ivela ezinkingeni zokungahambelani, hhayi ezinkingeni zokufihla. Qondanisa ukukhanya, ukugqama, kanye nokushisa kombala phakathi kwakho nesizinda, futhi ugweme izizinda ezinemibono ehluke kakhulu. Engeza isisekelo esithambile njengesithunzi esithambile, ukuthinta kokufiphala kwesizinda, noma umsindo oqhubekayo kuzo zonke izendlalelo ukuze isihloko sakho nesizinda sakho kuzizwe sengathi babelana ngekhamera efanayo.

Ungayisebenzisa kanjani i-AI Green Screen kumakholi e-Zoom noma ekusakazeni ngaphandle kwama-halo e-glitch?

Ukukhanya kubaluleke kakhulu kunalokho abantu abakucabangayo: ukukhanya okuqinile, ngisho nangaphambili kanye nesizinda esilula kunciphisa ukudideka kwemaski. Zinike ibanga ukusuka odongeni ukuze uhlukanise, futhi ugweme imibala yezingubo ehlangana nesizinda sakho. Uma ikhamera yakho yewebhu ibukeka “ilukhuni,” ukwehlisa ukucija kungasiza, ngoba imiphetho ecijile ngokweqile ingabangela ukufiphaza kanye nama-halo ekuhlukaniseni ngesikhathi sangempela.

Iyiphi ifomethi yokuthumela ngaphandle engcono kakhulu yamavidiyo esikrini esiluhlaza se-AI ngokusobala?

Uma udinga isizinda esibonakalayo ukuze uyisebenzise kabusha noma uyihlanganise, uzodinga ukuthunyelwa okusekela isiteshi se-alpha. Ama-workflow amaningi asebenzisa i-Apple ProRes 4444 ukuthola i-alpha esezingeni eliphezulu, ikakhulukazi uma uhlela ukwenza ukuhlanganiswa okwengeziwe kamuva. Uma ungadingi ukubonakaliswa, ukuthumela ividiyo yokugcina enesizinda esisha kulula futhi kugwema izinkinga zokuhambisana.

Iyiphi indlela "yokuxuba" uma isikrini esiluhlaza se-AI sokuchofoza kanye singahlanzekile ngokwanele?

Sebenzisa i-AI cutout njengesisekelo sakho, bese ubeka izilungiso ezisebenzayo esikhundleni sokuqala kabusha kusukela ekuqaleni. Engeza i-drag matte esheshayo ukuze ususe izindawo ezisobala zenkinga, upende izinto ezincane ezinyamalalayo, bese usebenzisa amathuluzi esikhashana/ahambisanayo ukuze ubushelelezi ukhanyise ozimele. Amathuluzi afana ne-After Effects (Roto Brush/Refine Matte) noma i-DaVinci Resolve (Magic Mask) avame ukuba ngcono lapha ngoba ahlanganisa i-AI nezilawuli zangempela.
