Capture/Save/Load/Playback In-game Video In Game...

Hello UnrealEngine Developers, My online searches are not effective in finding information that will show me how to Capture/Save/Load/Playback In-game Video In Game. The goal is to use short vid captures for animated icons in place of the standard static images. Ideas include taking several snapshots and flipbooking thru them on a rendertarget. I’m open to any and all recommendations to achieve this. Thanks in Advance.
