Hi there, I´ve got problem with splitting clips. I´ve added many clips on timeline and than split them to very small pieces. Everything seem to be okay. But, in preview and after export too, from unknow reason to me shows thumbnails of original clips. When player reach to split clip, always appear this frame and little lag is there too. Does anyone know how to fix it? I spend more than 6 hours of editing and have not power to do it again. Thank you
