I added a parameter in "addText" with which you can switch that automatic formatting on and off. Unfortunately I can't add it via elegant {{}}, because Visustella can only check the closing brackets if they are actually there. In case of fading in narrative text Visustella sees "{{123" partially, for example.
That is an unfortunate limitation between those two plugins.
For movies I got bad news. Both a movie and a narrative text try to block the game via the waitmode. A movie sets the wait mode to "video", which basically blocks everything until that waitmode is set to idle. Similarly, this plugin blocks everything by setting the waitmode to "narrative", so those two things can never work together.
There might be other plugins that let you arbitrarily play video files without setting a waitmode, but as it is, this unfortunately just doesn't work out.
