It is more simple that it seems, first I do the research of the historical event that i pretend to portray, second i play a custom battle with the game "Medieval 2 Total War" with the faccions and units that fit more with that historical event, and then save the replay. And finally i use an application called "cinematic editor for medieval 2 total war" and with that i make the scenes with the replay that i saved previously. That's how i did it.
