Make Video from Render Target

I have an Arch Viz scene and there are numbers of cameras around. Each one is a cinecamera component which is part of an Actor blueprint. I like to move them ahead slowly for 5 seconds and render a video file out of each without switch the camera.

As you know, we can take screenshot from different camera by using Render Target without switching view to them, now my question is, is there any method to record a video from Render Target`s image output?

You can try my plugin (runtime video recording) where I added experimental “record from render target” feature:
