I am writing this topic in regard to a very interesting effect I've observed while watching tennis games. An example can be found on the Facebook page called "Tennis Channel", e.g. the last posted video there with the shots of Grigor Dimitrov.
In the video, one can see that there is an effect of a "moving camera" that moves to the left/right when the footage is paused on a particular frame.
During this simulated movement of the camera the audience gets slightly blurred so this appears to be some video simulation or similar? I am pretty sure that there is no hawk-eye involved here. In addition to that there are other effects of zooming in and some "paint" alike effects on the relevant parts of the court.
How can I create such an effect?
