Ii-conduit okanye iitreyi ezikhuselayo zikhusela iintambo ekutyunyuzweni okanye ekukrwitshwe ziimpuku. Ukungahoywa kwezi ndlela kubiza iindawo ezibuthathaka kwigridi, nto leyo ekhokelela ekulahlekelweni kwesignali okanye ixesha elingakumbi lokungasebenzi.

IiNuances zoFakelo

Ukufakela izikhonkwane kubaluleke kakhulu njengentambo. Ukudibanisa? Kufuneka kucoceke kwaye kube ngokuchanekileyo. I-splice embi inokuthintela okanye isasaze ukukhanya, yonakalise amazinga edatha. Iifayibha zemowudi enye, ezinee-cores zazo ezincinci, zifuna ingqwalasela ekhethekileyo ukugcina ukusasazeka kwe-modal kwinqanaba elincinci.

Izikhokelo zoshishino zichaza imigangatho ye-gog radius kunye nomthwalo. Ukunamathela kwezi zinto kuthintela iintambo ukuba zingagugi ngaphambi kwexesha okanye zingaphulukani ne-bandwidth. Neempazamo ezincinci—ezifana nokujika okanye i-grimy splice—zinokunciphisa iminyaka yokusebenza kwenkqubo. Ukuhlolwa rhoqo kunye nabafaki abanamava kuyanceda kakhulu.
