A user on the forum had a blur effect in a video with an embedded logo and wanted to copy and paste the same effect in the same video without the embedded logo. 
This Part 1 tutorial shows how to create the blur effect, like masking a face, the mask, tracking the face with the blur mask, and copying the effects onto a similar video in a second movie.
You will see:

• Splitting a video clip
• Multiple movies
• Applying a mask to a video clip
• Applying an effect to a video clip
• Automatic object tracking
• Copying effects from one object to another

I used Video Pro X11, but the same thing can be done in Movie Edit Pro Plus/Premium the same way. Note that Video Pro X has a Source Window and a Project Temp Folder Window that Movie Edit Pro does not.

Part 2 of this tutorial shows a different way to use masks and effects, and how to put two masks on a video, as well as copying and pasting objects and effects between two movies.
