Tell me that you need to relieve Machinima. (The Elder Scrolls 5: Skyrim)

Seen on the Internet these videos. The best one is Dragonborn act 1-3, team some people created this film in 2013. Then I saw many cars 2014-2016. They were not such amazing quality as the above-mentioned dragonborn. I imagine about the process of creation. You need to create a plot, choose a suitable place(be it a house or a large field, and maybe a forest?), then you need to put your heroes, ask them the steps to choose the view, then to put sound cues in video editor.
And now to the point, I know all about the story, more or less clear with the voice acting and characters. I wonder how to set the necessary actions and make any angle. May have for this program or modification. You can try with the in-game camera, but how to get say gg to go on the road, and shoot it at the same time, or lose him and the second Persian two animations next to each other and catch the view. Help if my Machinima will be filmed, you'd love it.
