I made some close up pictures today from F1 once the camera was zoomed out which basically has the same effect as with soccer with small moving objects (not the best quality but you will get the point).

I have to add it is not always that bad as in the pictures when zoomed out. It seems to be depending on how the small objects and the camera is moving.
In movies I never get something like this. Also live TV without small moving objects looks great.
@QB Yes the stream compression might explain it. I think it can be somewhat mitigated but it will never look really good.
