My renders from sequencer are blank / black

Hi everyone, I am stuck when trying to render out a Niagara particle system. I see my Camera Cuts track as thumbnails with my content, i see the cameras little window full with content in the viewport when i have my CameraActor selected in World Outliner, but when i hit Capture Movie in Render Settings nothing is shown as output in the preview window. It is just black.

Any help would be much appreciated.
