What I want to do is have my title fade in over a clip that's playing in the background and blur the clip. I have no idea how to do this.
Create your text. Open the layer controls and look for the Opacity control in the Transform group. Keyframing this from 100% to 0% is your fade out.
Add a blur effect and keyframe the radius an iterations for more or less blur.
If you are unfamiliar with keyframes, then here's a tutorial.
This tutorial might have something similar to what you are looking for. It's focus is about creating templates but one of the projects create a title and racks the focus of the video behind the text title. The TUT is done in Hitfilm2 but is completely applicable to current versions.
