How to create a video for a map?

Ment, thank you! I'll create the next scene and try it out. But here's another problem: how do I place initially dead units on the map for the cutscene (like in the final cutscene of the first mission, "Dragon Wisdom")? Also, I'm making my third attempt at creating my own campaign. I've already created the first mission, written a couple of scripts (thanks to Ser9K's maps), and today I'll be working on the cutscenes (if you can give me some advice on the units). But objectively, I can't do it alone. If cutscenes can be checked as they are being created, scripts can only be reviewed after completing the mission. And that takes time. And some scripts can't be found anywhere... Although I've seen them in campaigns (both original and fan-made). Who can (and wants to) help me with this difficult task?
