08- Change video style
Yes! In the editor, find your selected style next to the "Project Settings", it will open a menu to change the style while editing the video.
Some options, like custom intros on Comics or Party do not exist on every style, so your timeline will adapt itself to the new style. If you switch back to the initial style, you'll find everything the same way you left it.
If you've already produced your video, you need to first choose "Edit as a new project", change the style in the editor, and produce the video again.
