How do I put an animated static overlay onto the camera?

I’m trying to make a title screen for my game but I’m stuck on adding an animated overlay onto the camera.
What I’m trying to do is a simple 3D title screen with 2D text and buttons but I want to add an animated static effect over the camera. Can anyone help me out here? I have all the textures needed for frames I’m just not sure how to go about making this.
