ingabe ipayipi lerabha lisebenza ngama-alpha matte

Ingabe i-Rubber Hose Isebenza ne-Alpha Mattes?

Ama-Alpha matte asetshenziswa kabanzi embonini yezithombe ukuze kudalwe imiphumela ehlukahlukene yokubuka. Avumela ukuhlukaniswa kwezinto ezahlukene zokwakheka, okunikeza abaculi ithuba lokusebenza ezingxenyeni ngazinye ngokuzimela. Ipayipi lerabha, ngakolunye uhlangothi, liyindlela yezithombe ezibonisa ukunyakaza kwalo okulula nokuguquguqukayo. Kodwa ingabe lawa masu amabili angasebenza ndawonye? Kulesi sihloko, sizohlola ukuhambisana kwe-rubber hose animation nama-alpha matte futhi sixoxe ngokuthi angahlanganiswa kanjani ukuze kuthuthukiswe ikhwalithi yokubuka iyonke yephrojekthi yezithombe ezinyakazayo.

Ukuqonda i-Animation ye-Rubber Hose

I-animation yepayipi yerabha iyisitayela sendabuko se-animation esathola ukuthandwa ekuqaleni kwekhulu lama-20. Yaziwa ngokunyakaza kwayo okuhlekisayo nokugqamile, kanti izitho zabalingiswa zibonakala njengepayipi yerabha eguquguqukayo. Lesi sitayela sivame ukugcizelela ukunyakaza okugelezayo kunokusebenza komzimba okungokoqobo. UMickey Mouse, uBetty Boop, no-Oswald the Lucky Rabbit bangabanye babalingiswa abadumile abalingiswa ngesitayela sepayipi yerabha.

Izinzuzo ze-Rubber Hose Animation

I-animation yepayipi yerabha inikeza izinzuzo eziningana ezenza kube ukukhetha okukhangayo kwaba-animator. Okokuqala, kulula kakhulu ukuyenza ibe yi-animator uma kuqhathaniswa nezitayela eziyinkimbinkimbi kakhulu. Ukulula kokunyakaza kuvumela aba-animator ukuthi bagxile ekulandiseni izindaba kunezindlela eziyinkimbinkimbi zabalingiswa. Lokhu kungaba usizo ikakhulukazi ekudaleni izithombe ezihlekisayo nezilula, lapho kugxilwe khona ekunyakazeni okusheshayo nokusheshayo.

Okwesibili, isitayela sepayipi yerabha siyakhanga futhi siyakhumbula. Ababukeli abaningi bahlobanisa lesi sitayela sopopayi nama-cartoon akudala, okuvusa umuzwa wokukhumbula izinto zakudala kanye nokukhanga. Ukusebenzisa lobu buhle kungasiza ekudonseni ukunaka kanye nesithakazelo sezilaleli eziningi, ikakhulukazi labo abakhulele bebuka ama-cartoon kusukela enkathini yegolide yopopayi.

U-Alpha Mattes ku-Animation

Ama-matte e-Alpha, aziwa nangokuthi iziteshi ze-alpha, ayisici esibalulekile emhlabeni we-animation kanye nemiphumela yokubuka. Avumela abaculi ukuthi bahlukanise izakhi ngaphakathi kokwakheka, okwenza kube lula ukulawula nokuhlanganisa izendlalelo eziningi. I-matte ye-alpha empeleni iyisithombe esimpunga esinquma ukucaca kwesithombe esihambisanayo.

Uma i-alpha matte isetshenziswa kungqimba lwesithombe noma lwevidiyo, isebenza njengemaski, iveza kuphela izingxenye zengqimba ezichazwe yizindawo ezimhlophe ze-matte. Okwamanje, izindawo ezimnyama zihlala zicacile, futhi amanani ampunga anquma izinga lokucaca. Le ndlela ivame ukusetshenziswa ekudaleni imiphumela efana nokulungisa umbala okhethiwe, ukuhlanganisa, kanye nokwengeza ukuthungwa okuyinkimbinkimbi ezingxenyeni ezithile zesithombe.

Ukuhlanganisa i-Rubber Hose Animation ne-Alpha Mattes

Uma ubheka kuqala, ukugqwayiza kwepayipi lerabha kanye ne-alpha matte kungase kubonakale njengokubhanqa okungavamile. Kodwa-ke, isitayela esibonakalayo esihlukile sokugqwayiza kwepayipi lerabha singazuza ekuguquguqukeni nasekulawuleni okunikezwa yi-alpha mattes. Ngokusebenzisa i-alpha mattes ngempumelelo, ama-animator angathuthukisa ikhwalithi iyonke ye-animation yabo yepayipi lerabha.

1. Ukuhlukaniswa Kwezinhlamvu Nokuthuthukiswa Kokwakheka

Enye indlela yokusebenzisa ama-alpha matte ku-animation yepayipi yerabha ukuhlukanisa izingxenye zomzimba ezithile zomlingiswa. Isibonelo, uma umlingiswa enezici zobuso noma izingubo ezihlukile, ukusebenzisa ama-alpha matte kungahlukanisa lezi zinto emzimbeni wonke. Lokhu kuvumela ukugqwayiza okuqondiwe futhi kuthuthukisa ukubukeka komlingiswa jikelele.

Ngaphezu kwalokho, ama-alpha matte angasetshenziswa ukwethula ukuthungwa okuyinkimbinkimbi namaphethini ezingxenyeni ngazinye zomlingiswa. Ngokusebenzisa ukuthungwa noma amaphethini ngokusebenzisa ama-alpha matte, abalingiswa bangaba nokujula okwengeziwe kanye nemininingwane, okwenza bakhange ngokubonakalayo.

2. Imiphumela Yokuhlela Nezizinda

Ama-matte e-Alpha angasetshenziswa ukudala imiphumela enezingqimba kanye nezizinda ku-animation yepayipi yerabha. Ngokuhlukanisa izinto nokwabela ama-matte e-alpha ahlukene, ama-animator angabeka izendlalelo eziningi, ngayinye inokunyakaza kwayo okuhlukile kanye nomklamo. Lokhu kunezela ukujula ku-animation futhi kuyenze ithakazelise ngokubonakalayo.

Ngaphezu kwalokho, ama-animator angadala ukwahlukana phakathi kwabalingiswa nesizinda besebenzisa ama-alpha matte. Ngokuhlukanisa abalingiswa nokusebenzisa i-alpha matte ecacile kungqimba yangemuva, abalingiswa bangabekwa kalula ezindaweni noma ezindaweni ezahlukene, okuthuthukisa amathuba okuxoxa izindaba.

3. Ukuguqulwa Kwesimo Esiguqukayo

Isici esihlukile se-animation yepayipi lerabha yikhono layo lokuguqula izimo nezilinganiso zabalingiswa ekunyakazeni koketshezi. Ama-matte e-Alpha angasetshenziswa ukuthuthukisa lezi zinguquko ngokuvumela izinguquko zesimo eziqondile nezilawulwayo. Ngokusebenzisa ama-matte e-alpha ukuchaza izindawo ezithile zokuguquka, ama-animator angadala izinguquko ezibushelelezi nezingenamthungo ngaphandle kokuthinta wonke umlingiswa.

4. Ukuhlanganisa Imiphumela Ebonakalayo

Ama-Alpha matte angasetshenziswa futhi ukufaka imiphumela ebonakalayo ku-animation yepayipi lerabha. Kungakhathaliseki ukuthi ukwengeza imiphumela yentuthu, umlilo, noma yezinhlayiya, ama-alpha matte ahlinzeka ngezindlela zokuhlanganisa le miphumela nabalingiswa futhi abaphile ngaphandle kokuphazamiseka. Lokhu kunezela ubunzima kanye nesithakazelo esibonakalayo ku-animation yepayipi lerabha, okwenza kube kuhle kakhulu futhi kuhehe.

5. Ukujula kanye nemiphumela ye-Parallax

Ukudala imiphumela yokujula kanye ne-parallax kungenye indlela yokuthuthukisa ukugqwayiza kwepayipi lerabha usebenzisa ama-alpha matte. Ngokubeka ama-alpha matte ahlukene ezingqimbeni ezimele izinto ezahlukahlukene ekwakhiweni, ama-animator angalingisa inkohliso yokujula futhi enze ukugqwayiza kugxile kakhulu. Le ndlela iwusizo kakhulu ekudaleni izigcawu ezishintshashintshayo noma ekumiseni izindiza ezahlukene ngaphakathi kokugqwayiza.

Isiphetho

Ekuphetheni, ukugqwayiza kwepayipi lerabha kanye nama-alpha matte kungasebenza ndawonye ngempumelelo, kunikeze ama-animator ukulawula okukhulu kanye nokuguquguquka kumaphrojekthi abo. Ngenkathi lawa masu amabili engase abonakale ephikisana, angahlanganiswa ukuze akhiqize ukugqwayiza okukhangayo nokuguquguqukayo. Ngokusebenzisa ama-alpha matte, ama-animator angaphakamisa ikhwalithi ebonakalayo yokugqwayiza kwepayipi lerabha, athuthukise imiklamo yabalingiswa, adale imiphumela yokuthungwa okuyinkimbinkimbi, futhi afake imiphumela ehlukahlukene ebonakalayo ngaphandle kokuphazamiseka. Ngakho-ke, uma ucabanga ukuzama ukugqwayiza kwepayipi lerabha, unganqikazi ukuhlola amathuba anikezwa yi-alpha mattes.
