Compositing (transparent BG) video or image sequences in Unreal

Here is my results so far. It does yield great chromakey. Only thing I need now is to somehow be able to bring in and use the audio. There was some old videos that show how UE used to bring in a separate audio file that you can re-sync, but apparently that was several versions ago. Also i can’t seem to be able to figure out how to have by object cast a shadow. It works fine with image sequences, cause i guess they have some sort of UV thing but there’s gotta be a way to do it with video as well.
