The reason that I got Xara in the first place was because of the ability to use it with Magix Movie Edit Pro (MEP) to create animated and static graphical overlays on a video clip, going from into Xara with the video as the background. I can rotoscope a mask (shape) the changes form over time. The result goes back to MEP as an overlay XAR object. It can be reopened from the XAR object in MEP. I am still amazed by this when it actually works properly, which is almost never. Between Xara and Magix, they have managed to break, fix, break, fix, make it unusable, partially fix... over the years. I complain each time. Right now it works, but only in the session as the XAR object gets emptied if the project is closed and reopened. I save the XAR file first or render out from MEP. Grrrr.
Still, it's a great feature.
