Image Trailing/After Image from Live Video

I am trying to create an afterimage of a video. Currently, I have a video playing on a Quad that can move around in 3D space. But I want to have an afterimage of the video trail behind it as it's moving. Essentially, as the "video" moves around, it leaves a static frame of the video behind it. I like to think of it as a flipbook that leaves behind a page when it moves. I've looked into a ton of Sprite after image posts but have not come across one that uses a video to create the Sprite images.

Any help you could provide would be fantastic, thank you so much!
