I-Chromakey: Ukususa Imvelaphi kunye neSkrini esiGreen vs iSkrini esiBlue
Iziphumo ezikhethekileyo ziya zisetyenziselwa ngakumbi kwiifilimu, uchungechunge kunye neemveliso ezimfutshane. Ukongeza kwiziphumo ezimangalisayo zedijithali, ngokuchanekileyo zizicelo ezifihlakeleyo ezisetyenziswa kakhulu, njengeChromakey.
Le yindlela yokutshintsha imvelaphi (kwaye ngamanye amaxesha nezinye iindawo) zomfanekiso ngomnye umfanekiso.
Oku kunokusukela kumntu osestudio ngequbuliso emi phambi kwephiramidi eYiputa, ukuya kumlo omkhulu wendawo kwiplanethi ekude.
Kule posi siza kugubungela:
Yintoni iChromakey?
Ukuqulunqa isitshixo seChroma, okanye i-chroma keying, ziziphumo ezikhethekileyo / ubuchule bokuvelisa emva kokuhlanganisa (ukwaleka) imifanekiso emibini okanye imijelo yevidiyo kunye ngokusekwe kumbala wemibala (uluhlu lwechroma).
Ubuchwephesha busetyenziswe kakhulu kumacandelo amaninzi ukususa imvelaphi kumxholo wefoto okanye ividiyo- ngakumbi ukusasazwa kweendaba, umfanekiso oshukumayo kunye nomdlalo wevidiyo.
Uluhlu lwemibala kuluhlu oluphezulu lwenziwa lukhanye, luveze omnye umfanekiso ngasemva. Ubuchwephesha be-chroma keying buqhele ukusetyenziswa kwimveliso yevidiyo kunye nokuveliswa kwasemva.
Obu buchule bukwabizwa ngokuba kukutshixa umbala, ukwahlula-hlula ukwaleka kombala (CSO; ikakhulu yi-BBC), okanye ngamagama ahlukeneyo okuhlukahlukana okunxulumene nombala okufana nescreen esiluhlaza, kunye isikrini esiblowu.
I-Chroma keying inokwenziwa ngemvelaphi yawo nawuphi na umbala olinganayo kwaye owahlukileyo, kodwa imvelaphi eluhlaza kunye noluhlaza okwesibhakabhaka isetyenziswa ngokuqhelekileyo kuba yahluke kakhulu kwi-hue kwimibala emininzi yesikhumba somntu.
Akukho nxalenye yombandela ofotwayo okanye ofotwayo inokuphinda ikhuphele umbala osetyenziswe ngasemva.
Ukhetho lokuqala omele ulwenze njengomenzi wefilimu IWindows Screen okanye Blue Screen.
Ukuqalisa ngezakho iibhodi zamabali ezishukumayo
Bhalisa kwincwadana yethu kwaye ufumane ukhuphelo lwakho lwasimahla ngeebhodi zamabali amathathu. Qalisa ngokuzisa amabali akho ephila!
Siza kuyisebenzisa kuphela idilesi yemeyile yethu kwincwadana yethu kwaye siyihloniphe eyakho wabucala
Ngawaphi amandla ombala ngamnye, kwaye yeyiphi indlela efanele imveliso yakho?
Zombini eziluhlaza okwesibhakabhaka kunye nohlaza yimibala engenzekiyo eluswini, ngoko ke ifanelekele abantu.
Xa ukhetha iimpahla kunye nezinye izinto ezisemfanekisweni, kufuneka ubeke ingqalelo ukuba umbala ongundoqo we-chroma awusetyenziswanga.

Lo ngumbala wesitshixo sechroma. Umbala awubonakali esikhumbeni kwaye unika "ukuchitheka kombala" okuncinci onokuthi wenze isitshixo esicocekileyo nesiqinile.
Kwimiboniso ngokuhlwa, naziphi na iimpazamo zihlala zinyamalala ngokuchasene nemvelaphi eluhlaza okwesibhakabhaka, enokuba luncedo.

Imvelaphi eluhlaza iye yanda ngakumbi kwaye ithandwa kakhulu kwiminyaka, ngokuyinxenye ngenxa yokunyuka kwevidiyo. Ukukhanya okumhlophe kuqulethe i-2/3 yokukhanya okuluhlaza kwaye ke ngoko kunokuqwalaselwa kakuhle kakhulu ngeechips zomfanekiso kwiikhamera zedijithali.
Ngenxa yokukhanya, kukho ithuba elikhulu "lokuchitheka kombala", oku kuthintelwe ngokufanelekileyo ngokugcina izifundo kude nesikrini esiluhlaza kangangoko kunokwenzeka.
Kwaye ukuba isamente yakho inxiba ijean eluhlaza, ukhetho lwenziwa ngokukhawuleza…
Nokuba yeyiphi na indlela oyisebenzisayo, ukukhanyisa ngaphandle kwethunzi kubaluleke kakhulu. Umbala kufuneka ube ngokulinganayo, kwaye izinto eziphathekayo akufanele zikhanye okanye zishwabene kakhulu.
Umgama omkhulu onobunzulu obulinganiselweyo bentsimi uya kunyibilikisa imibimbi ebonakalayo kunye ne-fluff.
Sebenzisa isoftware yechromakey elungileyo njengePrimatte okanye iKeylight, izitshixo ngaphakathi isoftware yokuhlela ividiyo (jonga olu khetho) ngokufuthi ukushiya into oyifunayo.
Nokuba awuzenzi iimuvi ezinkulu, unokuqalisa ngechromakey. Isenokuba bubuchule obungabizi kakhulu, ngaphandle kokuba isetyenziswe ngobuchule kwaye ayiphazamisi umbukeli.

Molo, ndinguKim, umama kunye nomthandi we-stop-motion onemvelaphi kwindalo yemidiya kunye nophuhliso lwewebhu. Ndinothando olukhulu lokuzoba kunye noopopayi, kwaye ngoku ndintywila kuqala kwihlabathi le-stop-motion. Ngebhlog yam, ndabelana nawe ngokufunda kwam.
