Is it possible....Buffer Visualizer + Matinee

Is it possible to render out an image sequence from specific channels in the buffer visualizer while using a matinee to animate the camera?

For example if I wanted to just render out the diffuse channel but keep the animation, how would I go about doing so?

You could do this with a post-process material on your camera.

We used it to get out a depth pass from a Matinee.

can you explain how to do this? I am switching from unity to ue4 and honestly i am somewhat confused
