If your doing an intro for the start of the gameplay, just say something you think is nice, greet the viewers, tell them what your doing in the video, then up to you after that. as for a visual intro with text and music, either learn to use some of the software, or get someone else if they know how to and have the spare time. If all else fails go to Flixpress, they have some templates you can use, but their not super duper. Mine is currently a flixpress one but i hate it But my viewers enjoy it so i keep it on.

Just be yourself.
