Freie Universität’s official font is “Source Sans.” Freie Universität Berlin’s corporate design does however permit the use of other non-serif (system) fonts such as Arial in your videos.

The color of the text in text overlays or intertitles may be white or black. Make sure that there is always sufficient contrast when using text in your videos.
Use the PowerPoint template on the  downloads page where the settings are already preset.

Do not use drop shadows or outlines to design your text.
