Lona ngokuvamile kuwumsebenzi onzima ngoba udinga ukulandelela wonke uhlaka lwezithombe ngesandla. Ngenhlanhla, enye isoftware yokukhiqiza ividiyo ethuthukisiwe inakho okuzenzakalelayo rotoscoping amakhono engasetshenziswa ukusheshisa le nqubo kakhulu.

Ukuze udale imiphumela ehlaba umxhwele ngempela usebenzisa izikrini eziluhlaza okwesibhakabhaka noma eziluhlaza, kubalulekile ukuthi ubeke isikhathi esanele kukho testing isibhamu sakho oyifunayo ezimeni ezahlukene zokubuka ngaphambi kokuqala kokudubula. Uma uqinisekisa ukuthi ukubukeka kokugcina okufunayo kufinyelelwa ngesikhathi sokukhiqizwa kwangaphambi kokukhiqiza khona-ke amathuba okuthi ukukhiqizwa kwangemuva kuzoba bushelelezi futhi kusebenze kahle!

Isiphetho

Ukusetshenziswa isikrini esiluhlaza sokukhiqiza ividiyo iyithuluzi eliwusizo kakhulu lokudala izithombe nezigcawu ezingokoqobo kuvidiyo. Ivumela abakhiqizi ukuthi bangeze imiphumela ekhethekile futhi wenze ividiyo ithandeke kakhulu. Isikrini esiluhlaza singakha umuzwa wochwepheshe kuvidiyo kuyilapho sivumela abakhiqizi ukuthi bengeze ukubukeka okuhlukile esigcawini.

Ngokusetshenziswa kahle nokuhlela, isikrini esiluhlaza singaba ithuluzi elizuzisa kakhulu ohlelweni lokukhiqiza ividiyo.

Isifinyezo

Ekuphetheni, isikrini esiluhlaza okwesibhakabhaka noma ubuchwepheshe besikrini esiluhlaza uvule amasango ezikhukhula ukuze kukhiqizwe amavidiyo. Ukusetshenziswa kwengemuva elilula kunganikeza ukuguquguquka okukhulu ekudaleni amashothi akholisayo nokubonwayo okumangalisayo. Nakuba ukusebenzisa ubuchwepheshe kungase kubonakale kunzima ekuqaleni, ngezinyathelo ezimbalwa nje ungakwazi ukudala imiphumela professional-level ezoletha amaphrojekthi akho ekuphileni.

Kubalulekile ukukhumbula ukuthi a indawo ekhanyiswe kahle ibalulekile ukuze wenze umphumela ube ngendlela efanele—kungenjalo uzobe ubona umsindo omkhulu kunesithombe. Ukulungiselela nakho kuyisihluthulelo, okusho ukuzilungiselela ngokomzimba nangokwengqondo. Qiniseka ukuthi khanyisa ingemuva lakho ngokulinganayo futhi uqonde ukuthi isebenza nini kangcono kumashothi wemiphumela ekhethekile. Uma sisetshenziswa kahle, isikrini esiluhlaza (noma isikrini esiluhlaza) sizoveza ubuhlakani bakho obuhle kakhulu futhi senze isitatimende kunoma iyiphi iphrojekthi yokukhiqiza amavidiyo - kungakhathaliseki ukuthi inkulu noma incane.
