This is a great PreViz tool, so that you can record in REALTIME, the FG, the BG, the Matte, and the Camera Track data (in FBX format, with zoom a focus), so that it can be finished in NUKE the final composition with the OTOY same ORBX file can be used for PreViz in UE4.
Hopefully this workflow will save a lot of work.
