Ingabe ukuguqula i-WebM kuzothatha isikhathi esingakanani?

Ngokuvamile amasekondi. Amafayela amancane asebenza ngokushesha, futhi izimo ezithatha isikhathi esingokoqobo ziyizinto ezisebenza umsebenzi ongokoqobo: ukurekhodwa okude okudinga ukuphinde kwenziwe ukukopela ifreyimu ngefreyimu, idokhumende elihlolwe lihamba nge-character recognition, noma iqembu elikhulu kakhulu. lapho ukuguqulwa kuphinde kuhlanganise idatha ekhona ihlala ngokushesha kungakhathaliseki ukuthi ihele likhulu kangakanani, ngoba akukho okuzosuswa.
