Peb tsuas xav tau lub teeb tawg tuaj thaum twg muaj cov highlights, nrog rau cov txheej duplicate tseem xaiv, mus rau Duab → Cov Kev Kho → Qhov Nres. Peb xav thawb cov qib kom txog rau thaum tag nrho cov duab yog xim dub tshwj xeeb tshaj yog qhov tseem ceeb (rub ob leeg rau qhov chaw kom ua tau qhov no).
Hloov txheej txheej rov qab rau overlay. Cov nyhuv tseem yuav ua kom zoo tshaj qhov peb nyob tom qab, tab sis tam sim no peb tuaj yeem tswj tau qhov uas peb xav tau.
Mus rau Lim → Plooj → Gaussian, thiab ntxiv ib co plooj rau txheej. Koj siv ntau npaum li cas rau koj, thiab yeej tawm los saj.
