Creating fading/blending-picture-background

Hey folks,

i am trying to create a onepager with a background that fades pictures one into another fullscreen,
a simple slideshow, which fades 4 pictures looped forever. Lets say background shows picture 1 for 4 seconds, then fades/blends for 1 second over to picture 2 and so on…
Is that possible to achieve in webflow in realtime? I can render a simple movieclip which will do the trick and use it as a background, but for quality reasons i would love to do this with webflow tools, but cant figure out how. Please, who can help?
