How to create a video for a map?

I understand. This program allows you to create sequential screenshots and automatically combines them into a video. That's why I'm asking you to open the editor, start the program, and in the editor, create some dialogue. After that, stop the program and upload the video somewhere (on the internet) with instructions recorded in the video. Is that clear?

This video tutorial should cover everything from the beginning (entering the editor) to the end (adding the dialogue to the mission). Thanks in advance!
