If you set your Gutenslider settings like in this example, you can achieve a continuously sliding banner effect. (Pro Version)
animation: slide
slides to show: 4
animation speed: 10 sec
autoplay: yes
autoplay -> slide duration: 0
autoplay -> pause on hover: no
Additionaly you want to set the animation function to linear with the css rule (replace with your slider id):
#gutenslider-gkej6bkl3 .swiper-wrapper {
transition-timing-function: linear;
}
