How to add delay to Scene Capture Component 2D?

Hello! I am using a live camera feed into UE4 and overlaying it (chroma keyed) onto a spectator Scene Capture Component 2D. It looks great and the VR player is overlayed into the game, but there is a delay with the live camera feed into UE4, the camera footage of the player lags behind the game. I want to delay the Scene Capture Component 2D to match the camera delay so that everything is perfectly in sync.

How could I accomplish this?

Does anyone know how to do this?

any update? how to synch rendering with external camera / mediaplayer (at least delay a bit)?

BUMP! Would really appreciate a solution for this.
