Sengiphetha, ukushintsha ifomethi yevidiyo kungaba umsebenzi wobuchwepheshe kodwa ongenzeka kunoma yimuphi umsebenzisi. Ngalesi sihloko, sihlole izindlela namathuluzi ahlukene akuvumela ukuthi uguqule ifomethi yevidiyo ngempumelelo nangempumelelo.

Kusukela ekusetshenzisweni kwesofthiwe eyisipesheli njengeziguquli zevidiyo kuya ekuhlelweni kwemibhalo yangokwezifiso, kunezinye izindlela eziguqulelwe ezidingweni namakhono omuntu ngamunye.

Kubalulekile ukuqaphela ukuthi ukushintsha ifomethi yevidiyo kungathinta ikhwalithi nosayizi wefayela eliwumphumela. Ngakho-ke, kuhle ukukhetha ifomethi efanele, ucabangela izici ezifana nesinqumo, i-codec, i-aspect ratio kanye namadivayisi lapho ividiyo izodlalwa khona.

Ukwengeza, kubalulekile ukuqinisekisa ukuthi unendawo yokugcina eyanele futhi ucabangele izidingo zokuhambisana zamadivayisi okuzodlalwa kuwo ividiyo yokugcina.

Ngamafuphi, ukwazi ukuthi ungayishintsha kanjani ifomethi yevidiyo kuyikhono elibalulekile kulabo abafuna ukulungisa amafayela abo emidiya kumapulatifomu nezidingo ezahlukene. Ngokusetshenziswa okufanele kwezindlela namathuluzi afanelekile, sonke singaguqula amavidiyo ngempumelelo nangaphandle kwezinkinga. Ngakho-ke, sizobe sisebenzisa wonke amandla esinikezwa yifomethi yevidiyo.
