I think Motion Monitor does filter it using a Butterworth Double Pass Filter at 10 Hz cutoff (whatever that means). But I don't know how that would smooth the data and get such a different result than Vizard got. Then again, I know nothing about the filter in Motion Monitor, so I don't know.

Is it even possible for the raw data to look so different from the "filtered" data from motion monitor? And is there any way to apply some sort of filter or smoother to Vizard so I can get a similar result?

You could average the data over a certain number of frames. Vizard 3.0 includes the ability to filter tracking data. In Vizard 2.5 you will have to implement it yourself, but it is not very difficult. Just have a list that stores the previous X number of samples and average the data every frame.
