Rendering Movie While Game is Running
I'm trying to use Unreal Engine to produce a large number of short procedurally generated movies for a computer vision project. Is there a way to call the movie renderer from within a game with a C++ or a blueprint and save the output?

I did not find a solution that would build movie making directly into the project. I'm using a Matinee actor and using the record button. It's not built into the project but since I just need the images, it works fine from within the Unreal Editor.
Another way I found (again, without copying the engine video capture code) was to add a blueprint function call to the screen capture console command after the "Event Tick" node on my camera actor. This works, but it was rather clunky. It runs slowly and if you're tracking the frame time of each image, it will be the actual render time of the capture. The method using the matinee actor worked better the image times would line up with the frame capture rate you set.
