360 Panoramic Export Pipeline

Here is one of the videos i made to test full vr on amongst other things: Epic UE4 Matinee Demo in Full VR (3D / 360 / Cardboard) - YouTube
The Showdown Demo will follow the next days.

But what I did not figured out so far but I want to know. Is there a way to save the frames in another format than hdr? I think a max quality jpg is sufficent for me.
But like I said, so far I can’t figure out how to safe another format. Anyone else did?
