Blender video edit > unreal engine 5 how?

I have a Mac mini 24GB RAM, Sonoma 14.1, Blender 3.3.1, video clips captured on iPhone 12 mini.

I take the video clips into Blender, make cuts and transitions, have all the settings needed in Blender to “render animation”.

I cannot see how this gets imported into Unreal Engine 5 once it is launched. All I see is something that looks like a chessboard. I do not see how I take that video edit into unreal engine.

Do I close Blender and import tha Blender file? I am baffled.

Thanks in advance.
